Cluttered or dark areas invite accidents. 2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes. ELECTRICAL SAFETY 1. A battery operated product with integral batteries or a separate battery pack must be recharged only with the specified charger for the battery. A charger that may be suitable for one type of battery may create a risk of fire when used with another battery. 2. Use battery operated product only with specifically designated battery pack. Use of any other batteries may create a risk of fire. 3. Use only with charger listed. PERSONAL SAFETY 1. Do not overreach. Keep proper footing and balance at all times.

Any power tool that cannot be controlled with the switch is dangerous and must be repaired. 2. Disconnect battery pack from product or place the switch in the locked or off position before making any adjustments, changing accessories, or storing the product. Such preventive safety measures reduce the risk of starting the product accidentally. 3. When battery pack is not in use, keep it away from other metal objects like:

paper clips, coins, keys, nails, screws, or other small metal objects that can make a connection from one terminal to another. Shorting the battery terminals together may cause sparks, burns, or a fire. 4. Keep the radio and its handle dry, clean and free from oil and grease. Always use a clean cloth when cleaning.
