English LEAVING THE BATTERY PACK IN THE CHARGER The charger and battery pack can be left connected with the charge indicator showing Pack Charged. WEAK BATTERY PACKS: Weak batteries will continue to function but should not be expected to perform as much work. FAULTY BATTERY PACKS: This charger will not charge a faulty battery pack. The charger will indicate faulty battery pack by refusing to light or by displaying problem pack or charger. NOTE: This could also mean a problem with a charger. Wall Mounting DCB107, DCB112 These chargers are designed to be wall mountable or to sit upright on a table or work surface. If wall mounting, locate the charger within reach of an electrical outlet. Mount the charger securely using drywall screws at least 1" (25.4 mm) long, screwed into wood to an optimal depth leaving approximately 7/32" (5.5 mm) of the screw exposed. Important Charging Notes 1. Longest life and best performance can be obtained if the battery pack is charged when the air temperature is between 65 °F and 75 °F (18-24 °C). DO NOT charge the battery pack in an air temperature below +40 °F (+4.5 °C), or above +105 °F (+40.5 °C). This is important and will prevent serious damage to the battery pack. 2. The charger and battery pack may become warm to touch while charging. This is a normal condition, and does not indicate a problem. To facilitate the cooling of the battery pack after use, avoid placing the charger or battery pack in a warm environment such as in a metal shed, or an uninsulated trailer. 3. 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 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. 4. 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 affect on the battery pack. 5. 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 charger before attempting to clean. 6. Do not freeze or immerse charger in water or any other liquid. WARNING: Shock hazard. Don't allow any liquid to get inside charger. Electric shock may result. CAUTION: 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. 8
