the bolt/nut is sufficiently tight, the tool stops
the impact and rotation after approximately
one second.
4. To turn off the auto-stop function, press and
hold the mode-selector button for three sec-
onds: the auto-stop will turn off.
ELECTRIC BRAKE
The Impact Wrench is equipped with an electric
brake. When the trigger switch is released, the
electric brake engages automatically to quickly
stop the rotation.
LED WORKLIGHT (FIG. 5)
The LED worklight,
located on the
base of the Impact
Wrench, will il-
luminate when
the trigger switch
is depressed. This
provides additional
light on the surface
of the workpiece for
operation in lower-
light areas.
The light will automatically turn off within 10
seconds after releasing the trigger.
INSTALLING THE BELT CLIP (FIG. 6)
1. Align the rib of
the belt clip with
the hole on the base
of the wrench.
2. Insert the screw
and tighten the
screw securely with
a screwdriver (avail-
able separately).
REMOVING THE BELT CLIP
1. Use a screwdriver (available separately) to
loosen the screw that attaches the belt clip to
the wrench.
2. Remove the screw and the belt clip.
INSTALLING AND REMOVING THE SOCKET (FIG.
7)
NOTICE: The friction ring, with certain plasticity
and strength, helps to prevent the socket from
disengaging from the output drive of the im-
pact wrench during the operation.
Always use the correct size socket for bolts and
nuts. An incorrect socket will result in inaccurate
and inconsistent fastening torque and/or dam-
age to the bolt or
nut.
1. Lock the trigger
switch by placing
the direction-of-
rotation selector
in the OFF (center)
position.
2. To install the
socket, push it onto
the output drive of the tool until it locks into
place.
3. To remove the socket, simply pull it off.
INSTALLING FASTENERS
NOTICE: Always keep the Impact Wrench at a
right angle to the fastener to avoid damaging
the fastener head.
To fasten:
1. Start threading the fastener by hand onto
or into its threaded counterpart (e.g. nut onto
bolt, or bolt into nut or threaded hole).
2. With the proper impact socket securely
mounted to the Impact Wrench, slide the impact
socket onto the nut or bolt head.
3. Place the direction-of-rotation selector in the
FORWARD position, and select
a suitable speed or the auto-stop function. Hold
the tool firmly while depressing the trigger
switch. The impact socket will turn the fastener
and the impacting action will begin when the
fastener encounters resistance.
To loosen:
1. With the proper impact socket securely
mounted to the wrench, slide the impact socket
onto the bolt head.
2. Place the direction-of-rotation selector in the
REVERSE position. Hold the tool firmly while
depressing the trigger switch. The tool will start
to impact immediately.
3. Once the fastener has “broken loose,” it will
start to unthread. Be careful that you do not al-
low a fastener to spin freely once it is no longer
engaged with its threaded counterpart, as it
may be thrown out of the socket.
IMPACTING TIPS
The proper fastening torque may differ depend-
ing on the type or size of the bolt, the material
of the workpiece to be fastened, etc.
NOTICE: Hold the tool straight along the axis of
the bolt or nut.
NOTICE: Excessive fastening torque may damage
the bolt/nut or socket. Before starting your job,
always perform a test operation to determine
