English 3. A cold battery pack will charge at about half the rate of a warm battery pack. The battery pack will charge at that slower rate throughout the entire charging cycle and will not return to maximum charge rate even if the battery pack warms. 4. If the battery pack does not charge properly: a. Check operation of receptacle by plugging in a lamp or other appliance; b. Check to see if receptacle is connected to a light switch which turns power off when you turn out the lights; c. Move the charger and battery pack to a location where the surrounding air temperature is approximately 65 °F - 75 °F (18 ° - 24 °C); d. If charging problems persist, take the tool, battery pack and charger to your local service center. 5. The battery pack should be recharged when it fails to produce sufficient power on jobs which were easily done previously. DO NOT CONTINUE to use under these conditions. Follow the charging procedure. You may also charge a partially used pack whenever you desire with no adverse effect on the battery pack. 6. Foreign materials of a conductive nature such as, but not limited to, grinding dust, metal chips, steel wool, aluminum foil, or any buildup of metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the cavity. Unplug the charger before attempting to clean. 7. Do not freeze or immerse the charger in water or any other liquid. WARNING: Shock hazard. Don't allow any liquid to get inside the charger. Electric shock may result. WARNING: Burn hazard. Do not submerge the battery pack in any liquid or allow any liquid to enter the battery pack. Never attempt to open the battery pack for any reason. If the plastic housing of the battery pack breaks or cracks, return to a service center for recycling. Storage Recommendations 1. The best storage place is one that is cool and dry, away from direct sunlight and excess heat or cold. 2. For long storage, it is recommended to store a fully charged battery pack in a cool dry place out of the charger for optimal results. NOTE: Battery packs should not be stored completely depleted of charge. The battery pack will need to be recharged before use.
