E. Safety information Never use this battery charger to charge other electrical appliances. Do not use any other charger or charging method to recharge the special batter-

ies. Using any other charger could result in fire, explosion, or damage the batter-

ies. This battery charger can be used by children aged from 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experi-

ence and knowledge if they have been given supervision or instruction concern-

ing use of the battery charger in a safe way and understand the hazards in-

volved. Children shall not play with the battery charger. Cleaning and user maintenance shall not be made by children without supervision. Although the battery charger is waterproof, never allow it to become immersed in water or other fluids. In addition, never use the battery charger if the terminals are wet. Never handle the power plug, charging plug or touch the charger contacts with wet hands. This could result in electric shock. Do not touch charger contacts with metallic objects. Do not allow foreign materi-

al to cause short circuit of the contacts. This could result in electric shock, fire, or damage the battery charger. Periodically remove dust from the power plug. Dampness or other issues could reduce the effectiveness of the insulation, resulting in fire. Never disassemble or modify the battery charger. This could result in fire or elec-

tric shock. Do not use with a power strip or extension cord. Using a power strip or similar methods may exceed rated current and can result in fire. Do not use with the cable tied or rolled up, and do not store with the cable wrapped around the charger main body. Cable damage can result in fire or elec-

tric shock. Firmly insert the power plug and the charging plug into the socket. Failure to in-

sert the power plug and the charging plug completely can result in fire caused by electric shock or overheating. Do not use the battery charger near flammable material or gas. This could result in fire or explosion. Never cover the battery charger or place other objects on top of it while charg-

ing. This could result in internal overheating leading to fire. Do not drop the battery charger or expose it to strong impacts. Otherwise, it could cause a fire or electric shock. Store the battery pack and battery charger out of reach of children. 7

Do not touch the battery pack or battery charger while it is charging. As the bat-

tery pack or battery charger reaches 104158 F (4070 C) during charging, touching it could result in burns. Do not use if the battery pack case is damaged, cracked, or if you smell any unu-

sual odors. Leaking battery fluid can cause serious injury. Do not short the contacts of the battery pack. Doing so could cause the battery pack to become hot or catch fire, resulting in serious injury or property damage. Do not disassemble or modify the battery pack. Doing so could cause the battery pack to become hot or catch fire, resulting in serious injury or property damage. If the power cable is damaged, stop using the battery charger and have it in-

spected at an authorized dealer. Do not turn the pedals or move the bicycle while the battery charger is connect-

ed. Doing so could cause the power cable to become tangled in the pedals, re-

sulting in damage to the battery charger, power cable, and/or plug. Handle the power cable with care. Connecting the battery charger from indoors while the bicycle is outdoors could result in the power cable becoming pinched and damaged in a doorway or window. Do not run over the power cable or plug with the wheels of the bicycle. Doing so could result in damage to the power cable or plug. Do not drop the battery pack or subject it to impact. Doing so could cause the battery pack to become hot or catch fire, resulting in serious injury or property damage. Do not dispose of the battery pack in a fire or expose it to a heat source. Doing so could cause fire, or explosion, resulting in serious injury or property damage. Do not modify or disassemble the e-Bike Systems. Do not install anything other than genuine parts and accessories. Doing so could result in product damage, malfunction, or increase your risk of injury. When stopped, be sure to apply the front and rear brakes and keep both feet on the ground. Placing ones foot on the pedal when stopped may unintentionally engage the power assist function, which could result in loss of control and seri-

ous injury. Do not ride the bicycle if there is any irregularity with the battery pack or e-Bike Systems. Doing so could lead to loss of control and serious injury. Be sure to check the residual battery capacity before riding at night. The head-

light powered by the battery pack will turn off soon after the residual battery ca-

pacity has decreased to where power assisted riding is no longer possible. Rid-

ing without an operating headlight can increase your risk of injury. Do not start off by running with one foot on a pedal and one foot on the ground and then mounting the bicycle after it has reached a certain speed. Doing so could result in loss of control or serious injury. Be sure to start riding only after you are seated properly on the bicycle seat. Do not press the pushing assist switch if the rear tire is off the ground. Other-

wise, the tire will turn at high speed in the air and you could be injured. 8

Do not use the wireless function with Bluetooth low energy technology in areas such as hospitals or medical institutions where use of electronic equipment or wireless equipment is prohibited. Otherwise, this could affect the medical equip-

ment, etc. and cause an accident. When using the wireless function with Bluetooth low energy technology, keep the display at a safe distance from heart pacemakers in use. Otherwise, the radio waves could affect the heart pacemaker function. Do not use the wireless function with Bluetooth low energy technology near au-

tomatic control equipment such as automatic doors, fire alarms, etc. Otherwise, the radio waves could affect the equipment and cause an accident through pos-

sible malfunction or unintentional operation. 9
