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.

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.
Anvil (Fig. E)

WARNING: Use only impact accessories. Non‑impact
accessories may break and cause a hazardous
condition. Inspect accessory prior to use to ensure that
it contains no cracks.

CAUTION: Inspect anvils, detent pins, and hog rings
prior to use. Missing or damaged items should be
replaced before use.
Place the switch in the locked off (center) position or remove
battery pack before changing accessories.

to allow the accessory to slide on. After accessory is
installed, the hog ring applies pressure to help provide
accessory retention.
To remove an accessory, grasp the accessory and firmly pull
it off.
Belt Hook (Fig. A)
Included with Some Models

WARNING: To reduce the risk of serious personal
injury, ONLY use the tool's belt hook to hang the
tool from a work belt. DO NOT use the belt hook
for tethering or securing the tool to a person or object
during use. DO NOT suspend tool overhead or suspend
objects from the belt hook.

WARNING: To reduce the risk of serious personal
injury, ensure the screw holding the belt hook
is secure.
iMPORTAnT: When attaching or replacing a belt hook, use
only the screw that is provided. Be sure to securely tighten
the screw.
A belt hook 8 can be be attached to either side of the tool
using only the screw 9 provided, to accommodate left‑ or
right‑handed users. If the belt hook is not desired at all, it can
be removed from the tool.
To move the belt hook, remove the screw
in place then reassemble on the opposite side. Be sure to
securely tighten the screw.
Mode Selector (Fig. A, D)
Your tool is equipped with a mode selector
you to select one of two speeds, Timber Screw™ mode, or
Precision Wrench™ mode. Select the mode based on the
maximum speed/torque needed and control the speed of
the tool using the variable speed trigger switch
Timber Screw™ Mode (Fig. D)
Timber Screw™ mode optimizes tool performance to help
increase the speed of wood driving applications such as with
lag bolts, lag screws and structural wood screws.
Precision Wrench™ Mode (Fig. D)
In addition to normal impacting modes, this tool features
the Precision Wrench™ mode which grants the user greater
control in both fastening and loosening applications.
When set in forward, the tool will fasten at 2500 RPM until
impact begins. The tool will then pause for 0.5 seconds
before continuing to impact at a rate of 3550 IPM, providing
the user with greater control and reducing the chance of
overtightening or damaging material.
When set in reverse, the tool will impact at a normal speed
and rate of 3550 IPM. Upon sensing that the fastener has
broken free, the tool will cease to impact and will reduce
speed to help prevent "run‑off" of loose hardware.
