• Do not place any object on top of the charger or place the charger on a soft surface that might block the ventilation slots and result in excessive internal heat. Place the charger in a position away from any heat source. The charger is ventilated through slots in the top and the bottom of the housing. • Do not operate the charger with a damaged cord or plug. Have them replaced immediately. • Do not operate the charger if it has received a sharp blow, been dropped or otherwise damaged in any way. Take it to an authorized service center. • Do not disassemble the charger; take it to an authorized service center when service or repair is required. Incorrect reassembly may result in a risk of electric shock, electrocution or fire. • The charger is designed to operate on standard 120V household electrical power. Do not attempt to use it on any other voltage. This does not apply to the vehicular charger. • 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 the charger cavities and ventilation slots. • Always unplug the charger from the power supply when there is no battery pack in the cavity. Charging a Battery (Fig. C) 1. Plug the charger into an appropriate outlet. 2. Insert and fully seat battery pack. The red charging light will continuously blink while charging. 3. Charging is complete when the red charging light remains continuously ON. Battery pack can be left in charger or removed. Some chargers require the battery pack release button to be pressed for removal.  WARNING: Only charge batteries in air temperature over 40 ° F (4.5 ° C) and below 105 ° F (+40.5 ° C). 4. Charger will not charge a faulty battery pack, which may be indicated by the light staying OFF. Take charger and battery pack to an authorized service center if light stays OFF. NOTE: Refer to label near charging light on charger for blink patterns. Older chargers may have additional information and/or may not have a yellow indicator light. 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 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. English 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. 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. 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. 2. 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. If charging problems persist, take the tool, battery pack and charger to your local service center. 3. 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 ASSEMBLY AND ADJUSTMENTS  WARNING: To reduce the risk of serious personal injury, turn unit off and remove the battery pack before making any adjustments or removing/ installing attachments or accessories. An accidental start‑up can cause injury. 7
