Installing and Removing the Battery Pack (Fig.D)
NOTE: For best results, make sure your battery pack is
fullycharged.
To install the battery pack
5
into the tool handle, align the
battery pack with the rails inside the tool’s handle and slide
it into the handle until the battery pack is firmly seated in
the tool and ensure that it does notdisengage.
OPERATION

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.
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.
Anvil With Hog Ring (Fig.C)
DCF921, DCF923
To install an accessory on the hog ring anvil, firmly push
accessory onto the anvil
3
. The hog ring
12
compresses
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.
Mode Selector (Fig.A, B)
Your tool is equipped with a mode selector
7
which allows
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
1
.
Timber Screw™ Mode (Fig.B)
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.B)
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.

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 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
9
that holds it
in place then reassemble on the opposite side. Be sure to
securely tighten thescrew.
