‑ Bolt: Ensure that all threads are free of rust and other
debris to allow proper fasteningtorque.
‑ Material: The type of material and surface finish of the
material will affect fasteningtorque.
‑ Fastening time: Longer fasten ing time results in
increased fastening torque. Using a longer fastening
time than recommended could cause the fasteners to be
overstressed, stripped ordamaged.
Proper Hand Position (Fig.E)

WARNING: To reduce the risk of serious personal injury,
ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal injury,
ALWAYS hold securely in anticipation of a suddenreaction.
Proper hand position requires one hand on the main
handle
10
.
To remove the battery pack from the tool, press the release
button
4
and firmly pull the battery pack out of the tool
handle. Insert it into the charger.
Variable Speed Trigger Switch (Fig.A)
To turn the tool on, squeeze the trigger switch
1
. To turn
the tool off, release the trigger switch. Your tool is equipped
with a brake. The anvil will stop when the trigger switch
is fully released. The variable speed switch enables you to
select the best speed for a particular application. The more
you squeeze the trigger, the faster the tool will operate. For
maximum tool life, use variable speed only for starting holes
orfasteners.
NOTE: Continuous use in variable speed range is not
recommended. It may damage the switch and should
beavoided.
Forward/Reverse Control Button (Fig.A)
A forward/reverse control button
2
determines the
direction of the tool and also serves as a lock‑offbutton.
To select forward rotation, release the trigger switch and
depress the forward/reverse control button on the right side
of thetool.
To select reverse, release the trigger switch and depress the
forward/reverse control button on the left side of thetool.
The center position of the control button locks the tool in
the off position. When changing the position of the control
button, be sure the trigger isreleased.
NOTE: The first time the tool is run after changing the
direction of rotation, you may hear a click on start up. This is
normal and does not indicate aproblem.
Worklight (Fig.A, B)
The worklight
6
is activated when the variable speed
trigger switch
1
is depressed. Pressing the worklight
switch
11
repeatedly will cycle through low illumination,
high illumination, andoff.
NOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as aflashlight.
Usage (Fig.A)

CAUTION: Ensure fastener and/or system will withstand
the level of torque generated by the tool. Excessive torque may
cause breakage and possible personalinjury.
1. Place the accessory on the fastener head. Keep the tool
pointed straight at thefastener.
2. Press variable speed trigger switch
1
to start operation.
Release variable speed trigger switch to stop operation.
Always check torque with a torque wrench, as the fastening
torque is affected by many factors including the following:
‑ Voltage: Low voltage, due to a nearly discharged battery,
will reduce fasteningtorque.
‑ Accessory size: Failure to use the correct accessory size
will cause a reduction in fasteningtorque.
‑ Bolt size: Larger bolt diameters generally require higher
fastening torque. Fastening torque will also vary according
to length, grade, and torquecoefficient.
