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
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;
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
