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 CRAFTSMAN 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.
nOTE: Do not attempt to mount CMCB101 charger under a
bench or table.
nOTE: Only mount CMCB101 charger with the charging
lights pointed upward toward the ceiling.
VersaTrack™

CRAFTSMAN chargers, except the CMCB101, can
be stored on CRAFTSMAN VersaTrack™ Trackwall.
Hooks and accessories are sold separately. Please
refer to the VersaTrack™ Trackwall accessory sheet for
further information.
