4. Charger will not charge a faulty battery pack, which may be indicated by the charging light(s) staying OFF. Take charger and battery pack to an authorized service center if light(s) stay(s) OFF. NOTE: Refer to label near charging light(s) on charger for blink patterns. Older chargers may have additional information and/or may not have a yellow indicator light. NOTE: To remove the battery pack, some chargers require the battery pack release button 11 to be pressed. Hot/Cold Pack Delay When the charger detects a battery pack that is too hot or too cold, it automatically starts a Hot/Cold Pack Delay, suspending charging until the battery pack has reached an appropriate temperature. The charger then automatically switches to the pack charging mode. This feature ensures maximum battery pack life. A cold battery pack may charge at a slower rate than a warm battery pack. The hot/cold pack delay will be indicated by the red light(s) continuing to blink but with the yellow light continuously ON. Once the battery pack has reached an appropriate temperature, the yellow light will turn OFF and the charger will resume the charging procedure. DCB118 and DCB1112 Chargers The DCB118 and DCB1112 chargers are equipped with an internal fan designed to cool the battery pack. The fan will turn on automatically when the battery pack needs to be cooled. Never operate the charger if the fan does not operate properly or if ventilation slots are blocked. Do not permit foreign objects to enter the interior of the charger. Electronic Protection System Li‑ion tools are designed with an Electronic Protection System that will protect the battery pack against overloading, overheating or deep discharge. The tool will automatically turn off and the battery pack will need to be recharged. 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 - 75° F (18° C- 24° C). DO NOT charge when the battery pack is below 40° F (4.5° C), or above 104° F (40° C). This is important and will prevent serious damage to the battery pack. 2. The charger and battery pack may become warm to the 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; English c. If charging problems persist, take the tool, battery pack and charger to your local service center. 4. You may charge a partially used pack whenever you desire with no adverse effect on the battery pack. Charger Cleaning Instructions  WARNING: Shock hazard. Disconnect the charger from the AC outlet before cleaning. Dirt and grease may be removed from the exterior of the charger using a cloth or soft non‑metallic brush. Do not use water or any cleaning solutions. Wall Mounting Some DeWALT 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, and away from a corner or other obstructions which may impede air flow. Use the back of the charger as a template for the location of the mounting screws on the wall. Mount the charger securely using drywall screws (purchased separately) at least 1" (25.4 mm) long, with a screw head diameter of 0.28-0.35" (7-9 mm), screwed into wood to an optimal depth leaving approximately 7/32" (5.5 mm) of the screw exposed. Align the slots on the back of the charger with the exposed screws and fully engage them in the slots. SAVE THESE INSTRUCTIONS FOR FUTURE USE The label on your tool may include the following symbols.
