ENGLISH
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.
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.
Worklight (Fig. A, D)
The worklight
6
is activated when the variable
speed trigger
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.
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.
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.
Proper Hand Position (Fig. G)
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
.
Installing and Removing the Battery Pack
(Fig. F)
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.
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 as described in the charger
section of thismanual.
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.
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.
