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 D WALT chargers are designed to be wall mountable
e
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.
