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
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.
