OPERATION
INSTALLING/REMOVING BELT HOOK (NOT
INCLUDED)
See Figure 1, page 9.
Look for the belt hook (AC10BC1) where you purchased this
product or call 1-866-539-1710.
 Align hole in belt hook with hole in the housing.
 Install screw to secure belt hook in place.
 To uninstall, remove screw then remove belt hook.
INSTALLING RUBBER BOOT (NOT
INCLUDED)
See Figure 2, page 9.
A rubber boot (AC13B06) may be installed to protect the tool
head and work surface. Look for the rubber boot where you
purchased this product or call 1-866-539-1710.
NOTE: For ease of installation, apply a dry lubricant, such
as talcum powder, to the inside of the boot before fitting
over tool.
 Stretch the rubber boot over the head of the wrench,
aligning tool chuck with chuck opening in boot.
 Pull the boot down fully until no space remains between
the tool head and boot.
INSTALLING/REMOVING BATTERY PACK
See Figure 3, page 9.
 Lock the switch trigger by placing the direction of rotation
selector in center position.
 Insert the battery pack into the product as shown.
 Make sure the latches on each side of the battery pack
snap into place and that battery pack is secured in the
product before beginning operation.
 Depress the latches to remove the battery pack.
For complete charging instructions, see the operator's
manuals for your battery pack and charger.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 4, page 10.
Set the direction of rotation selector in the OFF (center lock)
position to lock the switch trigger and help prevent accidental
starting when not in use.
Position the direction of rotation selector to the left of the
switch trigger for forward operation. Position the selector to
the right of the switch trigger to reverse the direction.
NOTE: The tool will not run unless the direction of rotation
selector is pushed fully to the left or right.
NOTICE:
To prevent gear damage, always allow the anvil
to come to a complete stop before changing the
direction of rotation.
WARNING:
Battery tools are always in operating condition.
Lock the switch when not in use or carrying at your
side, when installing or removing the battery pack,
and when installing or removing sockets.
VARIABLE SPEED SWITCH TRIGGER
See Figure 4, page 10.
The variable speed switch trigger delivers higher speed with
increased trigger pressure and lower speed with decreased
trigger pressure.
To turn the tool ON, depress the switch trigger. To turn it
OFF, release the switch trigger and allow the anvil to come
to a complete stop.
NOTE: A whistling or ringing noise coming from the switch
during use is a normal part of the switch function.
NOTE: Running at low speeds under constant usage may
cause the tool to become overheated. If this occurs, cool the
tool by running it without a load and at full speed.
INSTALLING AND REMOVING SOCKETS
See Figure 5, page 10.
Use only sockets designed for impact wrenches. Always
select the correct size impact socket for nuts and bolts.
CAUTION:
Using the wrong size socket may damage the
nut or bolt and cause the fastening torque to be
inaccurate or inconsistent.
 Remove the battery pack.
 Push the socket onto the anvil until the friction ring locks
it into place.
 To remove the socket, pull it away from the anvil.
MODE SELECTOR
See Figure 6, page 10.
Press the mode selector to cycle between Low (1) speed,
Medium (2) speed, High (3) speed, and Auto Mode (A).
Auto Mode offers protection from over-tightening fasteners.
It allows for greater control, reducing damage to fasteners
and work surfaces. If the tool is in Auto Mode and running
in the forward direction, it will automatically shut down once
it starts impacting. If the tool is in Auto Mode and running
in the reverse direction, it will automatically shut down after
impacting has completed.
