ments. 1-8 RMAX.book Page 9 Tuesday, January 17, 2012 3:06 PM Safety Precautions WARNING The unmanned helicopter for industrial appli-

cations is operated by way of radio signals. To prevent the helicopter from going out of control due to unexpected radio signal inter-

ference, pay careful attention to any radio signal interference before and during a flight. WARNING Select areas that are appropriate for takeoffs and landings, as described below. Failure to select an appropriate area could lead to an accident. G Select flat farm roads or vacant lots with minimal foot or vehicle traffic. G Check that there are no obstacles in the vicinity. G Check that there are no objects that could be picked up by the wind (such as mowed grass, plastic tape, plastic bags, etc.). WARNING Abort the flight or aerial application if poor weather conditions exist as described below. Failure to do so could pose operation diffi-

culties, which could lead to an accident. In addition, it could adversely affect the applica-

tion and the effectiveness of the sprayed chemicals. G Wind velocity in excess of 3 m/s at a height of 1.5 m above the ground. G Rain, fog, or lightning in the close vicinity. WARNING the maximum horizontal distance Keep between the operator and the helicopter within 150 m, and the flight altitude at 3 - 4 m

(from the ground or from the crop). If the dis-

tance is any greater, it will prevent the opera-

tor from monitoring the posture of the helicopter and adversely affect the signal reception conditions. For safety, further shorten the distance if there are any obstacles in the area. Failure to fly the helicopter within the maxi-

mum distance limit could lead to an accident. 1-9 within 150m 3-4m RMAX.book Page 10 Tuesday, January 17, 2012 3:06 PM Safety Precautions WARNING Adjust the load to leave some margin in the payload. A takeoff with a full payload requires maximum horsepower and careful flying technique. An excess payload at this point could lead to a serious accident. There-

fore, hover the helicopter to check that there is an ample margin in payload before con-

tinuing with the flight. (See page 4-10.) WARNING the helicopter exhibits If the YACS warning light illuminates, the GPS indicator light shows an abnormal con-

dition, irregular behavior, or an unusual symptom occurs

In case of radio signal interference, the system has a safety feature that alternately flashes the inner and outer lights of the red YACS warning lights and auto-

matically effects the flight control described on the following pages. Thoroughly familiarize yourself with this feature to take the appropriate actions. DANGER During signal interference, never approach the helicopter until the main rotor has come to a complete stop and the engine has stopped. If there are any people in the area, instruct them to leave the area immediately. WARNING G Do not fly any higher than 3 to 4 m (above the ground or crops). When radio signal interference occurs (i.e. when failsafe mode is engaged), the engine speed is automatically brought to idling state after 40 seconds. Flying at a higher altitude will cause the helicopter to descend abruptly. G Make sure to follow the Actions instructed in the manual. Failure to do so could cause the helicopter to move unex-

pectedly or descend suddenly once it recovers from the radio signal interfer-

RMAX.book Page 13 Tuesday, January 17, 2012 3:06 PM Pre-Flight Inspection Items G Poor GPS Reception (Outer Lights of GPS Indicator Light Are OFF) 1 In the event of radio signal interference, the inner and outer lights of the red YACS warning lights will flash alternately and the system will force the helicopter to descend quickly regardless of the flight mode. If the control radio signals recover while the helicopter is descending, the flight mode will switch automatically to operator con-

trol. For this reason, calmly move all the sticks on the transmitter to the neutral (center) position, and wait for the signals to recover. 2 If the helicopter is forced to land because the radio signals have not recovered, the engine is brought to idle. Depending on the terrain, weather, and flight conditions, the helicopter could overturn. If the helicopter overturns, never approach the heli-

copter, as the engine speed might not decrease. 3 After a forced landing, turn the throttle to the slowest position and wait for the radio signals to recover or the engine to stop. 4 If the radio signals do not recover after 1 minute from the time the radio signal interference occurred, the engine will stop automatically. After the rotor has come to a complete stop, approach the helicopter and turn OFF its main switch. 3-13 Pre-Flight Inspection Items Descends slowly after hovering Brake control Radio signal interference!

(Inner and outer YACS warning lights flash alternately.) RMAX.book Page 14 Tuesday, January 17, 2012 3:06 PM G Good GPS Reception (Outer Lights of GPS Indicator Light Are ON) 1 When radio signal interference occurs, the inner and outer lights of the red YACS warning lights will flash alternately, and the system will apply the brake and force the helicopter to hover regardless of the flight mode. Then, the helicop-

ter will automatically start descending slowly. If the control radio signals recover while the heli-

copter is descending, the flight mode will switch automatically to operator control. For this rea-

son, calmly move all the sticks on the transmitter to the neutral (center) position, and wait for the signals to recover. 2 If the helicopter is forced to land because the radio signals have not recovered, the engine is brought to idle.

(Warning pattern on GPS indicator light) The GPS control operates by receiving radio sig-

nals from 4 or more satellites. It may become inop-

erable depending on the surroundings, terrain, weather conditions, time zone, and other reasons. If the reception of GPS signals becomes poor while operating in a GPS control flight mode (SG, CG, or AG), a safety feature will cause the outer and inner lights of the orange GPS indicator lights to flash alternately. Then, the system will automatically effect flight control or switch the flight mode as described below. Thoroughly familiarize yourself with this feature to take the appropriate actions. G Operating in SG mode As the GPS signal reception worsens, the orange GPS indicator lights will cycle through outer lights ON > inner lights ON > OFF, and the brake control will be applied only in the longitudinal direction of the helicopter. At this point, quickly turn OFF the GPS control switch. Because GPS control cannot be used even before the GPS control switch is turned OFF, the helicopter will operate in the slow flight mode. This flight mode is not suitable for aerial application. In addition, GPS control will not resume even if the GPS signal reception improves. When the GPS control switch is turned OFF, the GPS indicator light will turn OFF and control will switch to S mode. Therefore, operate carefully. NOTICE If the stick on the transmitter is moved past the neutral (center) position to stop the heli-

copter when it is flying forward or backward in SG mode, the automatic brake control will be applied together with the operators brake control if the GPS control is canceled. As a result, the nose of the helicopter will tilt up to an excessive angle. G Operating in CG mode As the GPS signal reception worsens, the orange GPS indicator lights will cycle through outer lights ON > inner lights ON > OFF. Control will switch automatically to C mode. At this point, quickly turn OFF the GPS control switch and operate carefully. When the GPS control switch is turned OFF, the GPS indicator light will turn OFF. G Operating in AG mode As the GPS signal reception worsens, the orange GPS indicator lights will cycle through outer lights ON > inner lights ON > OFF. Control will switch automatically to A mode. At this point, quickly turn OFF the GPS control switch and operate carefully. When the GPS control switch is turned OFF, the GPS indicator light will turn OFF. 3-15 Pre-Flight Inspection Items RMAX.book Page 16 Tuesday, January 17, 2012 3:06 PM The reception of GPS radio signals can be adversely affected by conditions indicated below or due to other reasons. 1 Flying near obstacles such as mountains, trees, or buildings. 2 The antenna is surrounded by people. 3 Fewer satellites are available during certain time slots. 3-16 RMAX.book Page 17 Tuesday, January 17, 2012 3:06 PM Pre-Flight Inspection Items 3-17 RMAX.book Page 1 Tuesday, January 17, 2012 3:06 PM Pre-Flight Preparation and Inspection Preparation Up to the Day Before ............................................ 4-1 Recharging and Replacing Flight Transmitter Battery ...................4-1 Selecting and Setting the Sprayer ....................................................4-3 Preparing Fuel and Refueling ............................................................4-4 Preparation on the Day of Flight .............................................. 4-6 Transporting Procedure .....................................................................4-6 Radio Signal Interference Inspection ...............................................4-9 Payload Inspection ...........................................................................4-10 Selecting the Flight Mode ................................................................4-13 Displaying and Recording Flight Hours .........................................4-14 Installing and Removing Main Rotor Blades .................................4-15 Installing and Removing Side Covers ............................................4-16 4 Pre-flight Inspection ................................................................ 4-17 Transmitter Inspection .....................................................................4-18 Fuel Inspection .................................................................................4-19 Coolant and Oil Inspections ............................................................4-20 Rotor Blade Inspection ....................................................................4-22 Servo and Linkage Inspection .........................................................4-23 Self Monitor Inspection ....................................................................4-24 Radio Signal Distance Test .............................................................4-25 Tail Rotor Drive Belt Inspection ......................................................4-25 GPS System Inspection ...................................................................4-26 RMAX.book Page 1 Tuesday, January 17, 2012 3:06 PM Pre-Flight Preparation and Inspection Preparation Up to the Day Before Recharging and Replacing Flight Transmitter Battery WARNING Make sure to use a fully charged battery for the flight.

NOTICE Make sure to remove the main rotor blades before transporting the helicopter. 1 Use a truck to transport the helicopter. 4-8 RMAX.book Page 9 Tuesday, January 17, 2012 3:06 PM Pre-Flight Preparation and Inspection Radio Signal Interference Inspection Because this product is operated by wireless radio signals, the presence of radio signals with the same or neighboring frequency in the vicinity will cause the signals to cross, which will adversely affect the control of the flight. Before a flight, use the supplied radio signal monitor to check the radio frequencies that are being transmitted in the area. (See the operation manual of the radio signal monitor for its operation procedure.) During monitoring, make sure the power switch for the flight transmitter is turned OFF. WARNING G The unmanned helicopter for industrial applications is operated by way of radio signals. To prevent the helicopter from going out of control due to unexpected radio signal interference, pay careful attention to any radio signal interference before and during a flight. G Cancel the flight if you detect the same fre-

quency that you will be using in the vicin-

ity. Otherwise, the radio signal interference could render the helicopter out of control, and could lead to serious accidents. G Check for radio signal interference regu-

larly, including during breaks between flights. G Check for radio signal interference each time you move to another area. 4-9 RMAX.book Page 10 Tuesday, January 17, 2012 3:06 PM Pre-Flight Preparation and Inspection Payload Inspection The actual payload of this helicopter varies consid-

erably according its operating conditions

(weather, temperature, humidity, terrain, obstacles, etc.) and flying methods, as well as the helicopters individual differences. to Use the graph on the following page as a rule of thumb for adjusting the payload with some margin to ensure a safe aerial application flight. WARNING Adjust the load to leave some margin in the payload. A takeoff with the maximum payload requires maximum horsepower and careful flying technique. An excess payload at this point could lead to a serious accident. Make sure to observe the following:

G Refer to the payload graph and check the payload that meets your requirements. G Check the payload margin by hovering. G If the low speed warning flashes on the YACS warning light, this means there is not enough payload margin. Remove the chemical tank on the right side before per-

forming the flight. G If the position of the throttle stick immedi-

ately after takeoff is clearly high, this means that there is not enough payload margin. Remove the chemical tank on the right side before performing the flight. NOTICE G If the engine is cold or when flying for the first time after a periodic inspection, as a guide, adjust the payload to about half of the capacity. G Contamination of the main rotor blades by pollen, etc., will cause the payload capac-

ity to decrease. Clean it during breaks. G If the cushion tape has a peel or a damage, it can cause the payload capacity to decrease. Cancel the flight and request a repair by your dealer.

(2 times) Beep

(1 time) Fully charged Requires charging. Inoperable unless charged. G Check that the battery monitor light is not illu-

minated. This light operates in unison with the number of beeps of the buzzer. It flashes when the battery level is low. Afterwards, it will illumi-

nate to warn the operator. This condition indi-

cates that the battery level is almost empty, and it should be replaced with a fully charged battery. 2 Transmitter Operation Inspection When the power of the transmitter is turned ON, apart from the buzzer sounding to indicate the battery level, if the buzzer beeps in a 3-3-7 pat-

tern or the output light does not illuminate, the transmitter may be malfunctioning. If this occurs, cancel the flight and request a repair by your dealer. 3 Antenna Inspection Inspect the antenna to make sure it is not loose in the area where it is mounted to the transmitter. Extend the antenna and inspect it for looseness or rust. If the antenna is loose in the area where it is mounted, tighten the antenna. If the antenna is loose or rusted, replace the antenna.

During the initial stage of helicopter operation, the water pump may leak a small amount of coolant (10 to 20cc could leak from the drain hole at the bottom of the water pump, onto the absorbent pad provided on the frame). This nor-

mal condition occurs while the internal seal is being broken in. It will eventually stop with con-

tinued operation of the helicopter. 3 Radiator Inspect the radiator cap and the rubber hose connections for any coolant leakage. WARNING When necessary, remove the radiator cap only after the engine has cooled down. If the radiator cap is removed immediately after the engine has been stopped, when the coolant is extremely hot, the scalding liquid could shoot out and cause burns. 4 Engine Inspect the mating surface of the cylinder body and the oil seal for any oil leakage, and the cylin-

der head for any coolant leakage. 5 Transmission and Intermediate Transmission Inspect the mating surface of the transmission case and the oil seal for any oil leakage. A slight stain of coolant or oil does not indicate an abnormal condition. However, if the coolant or oil is leaking in a dripping manner, cancel the flight and request a repair by your dealer. NOTICE G Coolant leakage will adversely affect the cooling performance of the helicopter and cause it to overheat. G Oil leakage will reduce the internal lubrica-

tion of the transmission and damage the gears and bearings. 4-21 Radiator Cap Water Pump Cylinder Head Hose Radiator Transmission Case Intermediate Transmission RMAX.book Page 22 Tuesday, January 17, 2012 3:06 PM Rotor Blade Inspection Inspect the rotor blades for damage, dirtiness, and movement.

ages wobble, cancel the flight and request a repair by your dealer. WARNING G If the servos operate abnormally or the linkages wobble, they could adversely affect the control of the helicopter. G If the throttle operates abnormally, it could adversely affect engine control, which could cause the helicopter to go out of control. Self Monitor Inspection Inspect the illumination of the indicator lights on the self monitor for proper operation. 1 With the power for the transmitter turned ON, turn the main switch on the helicopter to START, and check that all lights illuminate for 2 seconds. 2 After the YACS control has completed configura-

tion, check the illumination of the indicator lights. flight indicator light illu-

Check that the minates.

Check that the check point indicator lights do not illuminate.

Check that the malfunction area indicator lights do not illuminate. If there is a problem with the illumination of the flight indicators or check point indicators, take the appropriate actions in accordance with the table on page 3-5. If a malfunction area indicator light illuminates, can-

cel the flight and request a repair by your dealer. WARNING Take the appropriate actions in accordance with the indicator lights. By ignoring the lights and continuing to fly, you will lose con-

trol of the helicopter and cause a serious accident. 4-24 RMAX.book Page 25 Tuesday, January 17, 2012 3:06 PM Pre-Flight Preparation and Inspection Radio Signal Distance Test Conduct a radio signal distance test to inspect that the system is operating normally. Before performing this inspection, turn the power switch for the transmitter to ON and the main switch for the helicopter to START. 1 Retract the antenna of the transmitter to its shortest length. 2 Have one person operate the transmitter while another person checks the helicopter, with an approximate distance of 50 m between the two. 3 Operate the transmitter and check that the ser-

vos operate accordingly. Make sure the light of the check point indicator is not lit. If the reach of the radio signals is less than 50 m, cancel the flight and request your dealer for repair. WARNING If the reach of the radio signals is too short, radio signal interference could render the helicopter out of control during flight. Tail Rotor Drive Belt Inspection Inspect the condition of the tail rotor drive belt and apply lubricant to the belt. Before performing this inspection, turn OFF both the main switch for the helicopter and the power switch for the transmitter. 1 Inspect for looseness in the tension of the belt. 2 Check that the belt is free of damage, abnormal wear, and noise during operation. 3 Apply a sufficient amount of the dealer-specified lubricant to the belt. If there is a problem with the belt, cancel the flight and request your dealer for repair. WARNING If there is a problem with the tail rotor belt, it could adversely affect the actuation of the tail rotor, which could cause the helicopter to go out of control. 4-25 50m Tail Rotor Drive Belt RMAX.book Page 26 Tuesday, January 17, 2012 3:06 PM GPS System Inspection Inspect to make sure the GPS system is operating normally. Before performing this inspection, turn the power switch for the transmitter to ON and the main switch for the helicopter to START. Inspect the illumination of the GPS indicator light by referring to the table on 3-9 - 3-10. If the light flashes for 3 minutes or more after the YACS control has completed configuration, this means the reception of the GPS signals may be poor. In this case, operate the flight only under YACS control. If the GPS indicator light does nei-

ther illuminate nor flash, the GPS system may have failed. In this case, request your dealer for repair. If the power for the flight transmitter is OFF, the light will stop illuminating in 1 minute, but this condition is normal. Turn the power for the flight transmitter ON.

dling the helicopter. Some of the contents may overlap the instructions given at the Academy. Never approach (or allow others to approach) within 20 m of the helicopter until the main rotor has come to a complete stop and the engine has stopped. Entering within 20 m of the helicopter could cause a serious accident. DANGER Preparation - Takeoff WARNING G Do not take off or land on sloping terrain, as this could cause the helicopter to overturn, or adversely affect its control. As a rule, the helicopter should take off and land on a level surface. Make sure to select an appropriate location before commencing a flight. G Select areas that are appropriate for takeoffs and landings, as described below. Failure to select an appropriate area could lead to an accident. Select flat farm roads or vacant lots with minimal foot or vehicle traffic.

Check that there are no obstacles in the vicinity.

Check that there are no objects that could get picked up by the wind (such as mowed grass, plastic tape, plastic bags, etc.). TIP G Do not operate the throttle stick while the outer YACS warning light is flashing. The engine will stop if the throttle stick is moved far up. G Do not operate the rudder excessively right before a takeoff, as this will cause the helicopter to move abruptly in the direction of the rudder after the takeoff. G During takeoff, do not turn ON the GPS control switch, as this could cause the helicopter to not ascend straight up. Takeoff - Hovering WARNING G Do not operate the sticks abruptly as this could cause the helicopter to lose balance and lead to an accident. G For the first flight of the day, allow the helicopter to hover for 1 or 2 minutes while the engine warms up, and check that the helicopter operates normally. Failure to do so will prevent the engine from attaining the proper power, which could lead to an accident. After takeoff, turn the GPS control switch ON while hovering. If this switch was ON during takeoff, turn it OFF while hovering, and turn it back ON. TIP 5-1 Chap5.fm Page 2 Wednesday, January 18, 2012 10:17 AM Flying Procedure Hovering - Flying WARNING G Adjust the load to leave some margin in the payload. A takeoff with the maximum payload requires maximum horsepower and careful flying technique. An excess payload at this point could lead to a serious accident. Therefore, hover the helicopter to check that there is an ample margin in payload before continuing with the flight. G Keep the distance between the operator and the helicopter within 150 m, and the flight altitude at 3 - 4 m (from the ground or from the crop). If the distance is any greater, it will prevent the opera-

tor from monitoring the posture of the helicopter and adversely affect the signal reception condi-

tions. For safety, further shorten the distance if there are any obstacles in the area. Failure to fly the helicopter within the maximum distance limit could lead to an accident. G Do not turn continuously while banking in one direction for more than 10 seconds, as this will cause the helicopter to drift as if the trim has shifted. G Do not turn in the SG mode. Because the operation method for this mode is different from other modes, the helicopter could make an unexpected movement. TIP Flying - Landing WARNING G Do not lower the throttle stick to the slowest position during a flight, as this could disrupt the engine speed control and cause the helicopter to descend abruptly. G If the YACS warning light or the GPS indicator light shows an abnormal condition, the helicopter exhibits irregular behavior, or an unusual symptom occurs (such as vibration, sound, coolant leakage, or foul odor), immediately land the helicopter in a safe area. Continuing with the flight in this state could lead to an accident. G Do not press the Engine Stop switch during a flight, as this will stop the engine and cause the helicopter to descend abruptly. However, to force the helicopter to land in case of an emergency, press the switch after making sure that it is safe to do so. G Abort the flight or aerial application if poor weather conditions exist as described below. Failure to do so could pose operation difficulties, which could lead to an accident. In addition, it could adversely affect the application and the effectiveness of the sprayed chemicals. Wind velocity in excess of 3 m per second at a height of 1.5 m above the ground.

Rain, fog, or lightning in the close vicinity. G Observe the following until the engine has come to a complete stop after landing:

Do not turn OFF the power of the flight transmitter.

Do not take remove or replace the battery in the transmitter. Failure to observe these precautions will trip the failsafe device (speed control turns ON auto-

matically), which will cause the engine to accelerate suddenly. During a takeoff or landing, if the engine speed does not decrease even if the throttle stick is low-

ered to the slowest position, calmly turn the YACS control switch OFF. This symptom could occur if a takeoff operation is aborted or if there are a considerable number of landing shocks when the helicopter lands. TIP 5-2 4 1 2 RMAX.book Page 3 Tuesday, January 17, 2012 3:06 PM Flying Procedure Engine Starting Pre-start Checks 1 Check that the flight mode selector switch on the helicopter is set to the position that you have selected.

To use the A or AG mode, turn the switch to A.

To use the C or CG mode, turn the switch to C.

To use the S or SG mode, turn the switch to S. See page 4-13 for a detailed description of the flight modes. 2 Check that the sprayer selector switch is set to the position of the sprayer that you will be using.

When using the liquid sprayer, turn the switch to or

Check the battery level (the buzzer should beep a minimum of 3 times).

Check that the YACS control switch is ON and the GPS control switch is OFF. 4 Turn the main switch on the helicopter to START.

Check that all the lights on the self monitor illu-

minate for 2 seconds.

Check all of the lights of the temperature sen-

sor monitoring LED. TIP Currently, exported. the granular sprayer is not 5-3 RMAX.book Page 4 Tuesday, January 17, 2012 3:06 PM 5 The SETTING light on the check point indicator flashes approximately 3 times (for 10 seconds), and the system performs YACS control configu-

ration and self checks. Check that all the red YACS warning lights on the back of the helicopter illuminate during configuration. TIP G Do not move the helicopter while the light is flashing. G Configuring the YACS control with the heli-

copter tilted could cause errors. Therefore, it is recommended to select a flat area for this purpose. G If the light illuminates on the flight indicator, first turn the main switch OFF;

light then, turn it to START. If the illuminates again or if the light continues to flash, contact your dealer for repair. If there are no problems, the light of the flight indicator will illuminate, indicating that the YACS control configuration has completed. 6 After the YACS control configuration has com-

pleted and the YACS warning light has turned OFF, the outer lights of the GPS indicator will flash and the GPS control configuration will start.

The outer GPS indicator lights will flash while GPS control is being configured.

The outer GPS indicator lights will change from flashing to constant illumination when the GPS control configuration has completed (which take about 3 minutes).

After the lights illuminate, turn ON the GPS control switch on the transmitter. Then, check that all the GPS indicator lights illuminate.

After checking that all lights illuminate, turn OFF the GPS control switch. TIP G Step 5 completes the pre-start checks if you will not be using GPS control or if you will be using it later during the flight. G The length of time it takes to complete the GPS control configuration varies accord-

ing to GPS signal reception. If it takes too long (the lights do not illuminate after 3 minutes), you will not be able to use GPS control in the AG, CG, or SG mode. Oper-

ate the helicopter under YACS control until the signal reception improves, which will be indicated by the illumination of the outer lights. Flying Procedure 5 Outer lights flashing

trol panel. TIP Attempting to start the engine without oper-

ating the decompression lever could cause the engine not to start or accelerate the wear of the battery and the starter motor. 2 Pull and raise the starter lever on the side cover as needed. TIP G Use the starter lever if the engine is cold. G Do not use the starter lever if the engine is warm, such as restarting after a flight. 3 Check that the elevator trim lever, rudder trim lever, and aileron trim lever are in center posi-

tion. WARNING If the elevator trim lever, rudder trim lever, and aileron trim lever are not in center posi-

tion, the helicopter might not ascend straight up at takeoff. 4 Make sure the throttle stick on the transmitter is in its slowest position. TIP At this time, keep the throttle trim lever set to the lowest position. 5-5 Decompression Lever Starter Lever Elevator Trim Lever Rudder Trim Lever Throttle Trim Lever Aileron Trim Lever Throttle Stick RMAX.book Page 6 Tuesday, January 17, 2012 3:06 PM Flying Procedure 5 Stand on the left side of the helicopter, and while securely supporting the main rotor, keep the throttle stick at the slowest position with your right thumb, and press the starter switch with your left hand. WARNING Support the main rotor with your body as shown in the illustration. Otherwise, the rotor could strike and injure you if the helicopter is improperly adjusted (such as the idle speed being too high or the clutch being engaged). TIP G If the engine does not start within 5 sec-

onds after pressing the starter switch, wait about 10 seconds to allow the battery volt-

age to recover. Then, press the starter switch again. G The safety device will trip and prevent the starter motor from operating if any of the following conditions have not been met:

Main switch is in the START position.

The power switch of transmitter is ON.

The throttle stick of the transmitter is in the slowest position. 6 After the engine has started, return the decom-

pression lever and the starter lever to their origi-

nal position. WARNING G Failure to return the decompression lever to its original position will decrease engine performance, which could lead to an acci-

dent. G Failure to return the starter lever will pre-

vent the engine speed from increasing, cause the spark plugs to become fouled, the engine to stop during flight, and lead to an accident. 5-6 RMAX.book Page 7 Tuesday, January 17, 2012 3:06 PM Flying Procedure 7 After the engine speed has stabilized, turn the main switch to the FLIGHT position. DANGER G Before turning the main switch to FLIGHT, check again that the throttle stick on the transmitter is in its slowest position. If the throttle stick is raised, the main rotor or the tail rotor could spin and cause a serious accident. G The safety device will trip when the main switch is in the START position, prevent-

ing the engine speed from increasing above a predetermined value. If you hear an abnormal sound from the engine, do not turn the main switch to the FLIGHT position. Instead, turn it OFF and check the areas that are possibly affected. NOTICE Leaving the engine idling for more than 1 minute could stain the spark plug, or decrease the cooling performance of the engine. 8 While making sure that the throttle stick does not rise, quickly walk away from the helicopter, to a minimum distance of 20 m. DANGER Never turn your gaze away from the helicop-

ter when walking away from it. Main switch 20m or more 5-7 RMAX.book Page 8 Tuesday, January 17, 2012 3:06 PM Takeoff Precautions and Checks Flying Procedure Takeoff Procedure 1 Start the takeoff operation after the outer YACS warning lights have finished flashing, and all lights are OFF. 2 Gradually raise the throttle stick to enable the control to automatically increase the engine speed. 3 Slowly move the throttle stick up to take off. WARNING Do not operate the sticks abruptly as this could cause the helicopter to lose balance and lead to an accident. TIP G If the throttle stick is moved far up while the outer YACS warning lights are flashing, the engine will stop. G Do not operate the rudder excessively right before a takeoff, as this will cause the tail to move abruptly in the direction of the rudder during a takeoff. G During takeoff, do not turn ON the GPS control switch, as this could cause the helicopter to not ascend straight up. Throttle Stick 5-8 RMAX.book Page 9 Tuesday, January 17, 2012 3:06 PM Flying Procedure Post-Takeoff Checks Perform the following checks:

1 While the helicopter is hovering, make sure the helicopter behaves normally in response to the operations of the sticks. 2 When the sticks are kept still in their neutral posi-

tion while the helicopter is hovering, the helicop-

ter will drift front-and-back and side-to-side, depending on wind conditions. If the helicopter drifts constantly in one direction, land it in a safe area to make fine adjustments at the trim lever of the transmitter. WARNING For the first flight of the day, allow the heli-

copter to hover for 1 or 2 minutes while the engine warms up, and check that the helicop-

ter operates normally. Failure to do so will prevent the engine from attaining the proper power, which could lead to an accident. TIP After takeoff, turn the GPS control switch ON while hovering. If this switch was ON during takeoff, turn it OFF while hovering, and turn it back ON.

Flying Procedure Main switch 5 Turn OFF the power switch on the transmitter. WARNING Observe the following until the engine has come to a complete stop:

Do not turn OFF the power of the flight transmitter.

Do not take the battery out of the transmit-

ter. Failure to observe these precautions will trip the failsafe device (speed control turns ON automatically), which will cause the engine to accelerate suddenly. 5-12 RMAX.book Page 13 Tuesday, January 17, 2012 3:06 PM Flying Procedure Precautions for First Flight After Periodic Inspection Fuel After your dealer performs the complete inspection flight for the periodic inspection, the fuels are drained from the fuel tank and the carburetor, to prevent the fuel from becoming old during your storage. When flying for the first time, create a mixed fuel with fresh gasoline purchased at a gasoline station shortly before flying (within 1 week), and refuel to maximum capacity. Never use leftover fuel as it could cause the engine to stop or operate poorly. NOTICE Onboard Battery Since the fuel has been drained, it will take a while before the fuel circulates into the carburetor. If the engine does not start within 5 seconds after pressing the starter switch, wait about 10 seconds to allow the battery voltage to recover and the starter motor to cool down. Then, press the starter switch again. If the rotation of the starter motor is weak, replace the onboard battery, or have your dealer recharge it with the dedicated recharger. Never charge with a recharger for car batteries, or connect to a car battery using a jumper cable. The electronics (computers) in the helicopter could malfunction. NOTICE First Flight Procedure In the periodic inspection, various parts of the helicopter are inspected, and a complete inspection flight is per-

formed. However, when flying for the first time after a periodic inspection, at a practice session, for example, fly the helicopter gently as a means for the operator to familiarize himself with the various areas of the helicop-

ter as well as its maneuverability. 1 Fill up the tank with fresh fuel. Keep the chemical and water load to one half of the normal load. 2 Perform pre-flight inspection. 3 After the engine starts, take off and hover no higher than 1 m above the ground for 2 minutes or longer. 4 Next, while hovering 2 to 3 m above the ground, fly gently with flare angle of 10 degrees or less, at a flight velocity of 10 km/h or less, for 10 minutes or longer. During this time, make sure that there is no vibration in the helicopter, abnormal sound, or other abnormal behavior in response to the various stick operations. 5 When landing for tasks such as refueling, always wait until the engine has stopped, and the main rotor has stopped rotating, then open the side cover to visually check the coolant and oil leakage. 6 After the flight, perform post-flight inspection, cleaning and servicing tasks. 5-13

ter to go out of control. Antenna Inspection Inspect the antenna to make sure it is not loose or rusted at the area where it is mounted to the heli-

copter. Before performing this inspection, turn OFF both the main switch for the helicopter and the power switch for the transmitter. Peel the dust cover from the base of each antenna pole and make sure the antenna poles are not loose or rusted. If they are loose or rusted, request a repair by your dealer before the next flight. WARNING If the antenna is loose or rusted, it will affect the reception of control signals, which could cause the helicopter to go out of control dur-

ing flight. Dust Covers 6-4 RMAX.book Page 5 Tuesday, January 17, 2012 3:06 PM Post-Flight Inspection and Cleaning Post-Flight Cleaning and Servicing Agricultural chemicals, dust, dead bugs, and pollen could adhere to the helicopter after an aerial appli-

cation. If they remain stuck to the helicopter, they will cause a chemical reaction, which will lead to rust, insufficient lubrication, sealant deterioration, and discoloring. To prevent these problems, use the methods described below to clean and service the helicopter after a flight, in preparation for the next flight. While cleaning, check all areas of the helicopter for any damage, abnormal wear, loose fasteners, etc. WARNING The helicopter is very hot immediately after a flight. Therefore, to prevent burns, clean it only after its temperature has lowered suffi-

ciently. NOTICE Washing the helicopter with water will cause a sudden change in temperature, which could create problems in electrical parts. Therefore, clean it only after its temperature has lowered sufficiently. 6-5 Post-Flight Inspection and Cleaning RMAX.book Page 6 Tuesday, January 17, 2012 3:06 PM Washable Areas 1 Side covers They may be washed only after they have been removed from the helicopter. Do not wash them in the installed state because the water could splash on other parts. 2 Tail body Clean it carefully while making sure to prevent the GPS system and the gyro sensor from direct contact with water. 3 Leaves and runners 4 Radiator Clean it by using caution not to damage the fins. NOTICE Do not use a high-temperature, high-pres-

sure cleaner to clean areas 1 to 4 above, as it could damage the film and paint on the sur-

face. After cleaning the washable areas of the heli-

copter with water, ensure to wring out your cloth before you wipe the moisture off the surface. 6-6 RMAX.book Page 7 Tuesday, January 17, 2012 3:06 PM Post-Flight Inspection and Cleaning Non-Washable Areas WARNING The helicopter and the transmitter have a drip-proof construction and not a water-proof construction. Therefore, do not use water directly on areas other than those indicated in the previous section. Failure to observe this precaution could cause the electric parts or the sliding areas to malfunction, which could lead to a serious accident. 1 GPS System and Azimuth sensor Washing these areas with water will cause them to malfunction as a result of exposure of the internal components to water. Therefore, use a soft, moist cloth that has been wrung out to wipe the dirty areas. 2 Control Panel Washing these areas with water will cause the hour meter, GPS antenna, switches, and the monitor lights to malfunction as a result of expo-

sure of the internal components to water. Therefore, use a soft, moist cloth that has been wrung to wipe the dirty areas. 3 Main and Tail Rotor Blades Washing these areas with water will cause the rotors to lose their balance and create vibrations as a result of exposure of the internal compo-

nents to water. If the rotor surface is dirty, use household deter-

dent. 1-5 R-max.book Page 6 Tuesday, January 17, 2012 3:08 PM Safety Precautions Using Registered Agricultural Chemicals Use nationally registered agricultural chemicals, and use them properly by reading the usage instructions and precautions included in the manual for each respective chemical. WARNING Do not use agricultural chemicals other than those registered. Failure to do so could expose animals, plants, or people to agricul-

tural chemicals for which the operator will be held socially responsible. WARNING Control and handle agricultural chemicals strictly in accordance with their manuals. Negligent control and improper handling of agricultural chemicals could lead to chemical pollution or health hazards. 1-6 R-max.book Page 7 Tuesday, January 17, 2012 3:08 PM Safety Precautions Spray Chemical Since the agricultural chemical is diluted at a low dilution rate, make sure to observe the following:

(1) Agricultural Chemical G Use nationally registered agricultural chemicals. G In low-volume liquid spraying, the characteristics of the agricultural chemical can easily change when mixed with other agricultural chemicals, and may produce solids or turn to a gum-like state. When mixing, use agricultural chemicals that have been checked in advance for physio-

chemical change, compatibility with the sprayer, mixture toxicity, etc. G Spreading agents (surface active agents) cannot be added.

(2) Dilution Water For dilution water, make sure to use tap water. Do not use agricultural water, as this could lead to debris clogging or characteristic change in the agri-

cultural chemical. Tap Water Label Agricultural Water

(3) Dilution Rate For example, to make 8 agricultural chemical diluted to 8x, dilute 1 agricultural chemical with 7 water). This will make 8 of spray solution of an of of tap water (dilution of spray solution. Agricultural chemical: 8 Tap water:

8 chemical) = 7 1/8 = 1

- 1

(agricultural Since flowable and water-dispersible chemicals can easily precipitate, combine and mix them well just before aerial application flight. 1-7 Chemical Tap Water Spray Solution R-max.book Page 8 Tuesday, January 17, 2012 3:08 PM Pouring the Spray Solution G Check the inside of the chemical tank (into which the solution will be poured), the check valve, the strainer section, and the filter for any debris or sediments. If you find any debris or sediments, make sure to remove them before pouring the solution. G Keep the chemical tank load to 8 or less per side (16 combined for left and right tanks). TIP G For higher altitudes and temperatures, decrease the load. G For information on load capacity, see the operation manual for the helicopter. Safety Precautions Check Valve Strainer Chemical Tank Filter in the Chemical Tank 1-8 R-max.book Page 9 Tuesday, January 17, 2012 3:08 PM Safety Precautions Usage Precautions Stop the engine when replenishing the chemical.

Low-volume liquid spraying at 7.5m spray width, 8L/ha

Left and right nozzles are selected

The GPS signal reception is good (i.e. the outer GPS indicator lights are ON) The state of the flight mode selector switch on the helicopter and the GPS control switch on the flight transmitter are irrelevant. G When the center nozzle is used, the speed-dependent function does not work, and discharging is done in proportion to a constant volume set by the spray volume adjuster on the flight transmit-

ter. 1 Switch the sprayer selector switch on the flight control panel to

. 2 Set the spray volume adjuster and the spray noz-

zle settings according to Spray Specifications Settings on page 4-7. TIP If the flight velocity exceeds 20km/h, only the outer lights of the YACS warning lights illumi-

nate. If this happens, drop the flight velocity to 20km/h or less. Sprayer Selector Switch YACS Warning Light GPS Indicator Light Only the outer lights of the YACS warning lights illuminate If the GPS signal reception is poor (the outer GPS indicator lights are ON), the speed-dependent function does not work, and the chemical is discharged at a constant rate set by the spray volume adjuster on the flight transmitter. During a GPS-controlled flight, if the GPS signal reception worsens (GPS indicator lights cycles a pattern outer lights ON > inner lights ON > OFF), the speed-dependent function does not work, and the chemical is discharged at a constant rate set by the spray volume adjuster on the flight transmitter. In this case, immediately turn OFF the GPS control switch according to the operation manual for the helicop-

ter. 4-6 R-max_4.fm Page 7 Wednesday, January 18, 2012 10:16 AM Spraying Method Spray Specifications Settings Set the spray volume adjuster and spray nozzles according to the chemical to be used. Spray Specifications Low-Volume Liquid Spraying Right and Left Nozzles Center Nozzle Spray Volume
