Variable Speed Trigger and Forward/Reverse
Control Button (Fig. E)
The tool is turned on and off by pulling and releasing the
variable speed trigger 3 . The farther the trigger is depressed,
the higher the speed of the tool. Your tool is equipped with
a brake. The anvil will stop as soon as the trigger switch is
fully released.
A forward/reverse control button
direction of the tool and also serves as a lock‑off button.
• To select forward rotation (clockwise), release the trigger
and depress the forward/reverse control button on the right
side of the tool.
• To select reverse (counterclockwise), depress the forward/
reverse control button on the left side of the tool.
nOtE: The centre 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: Continuous use in variable speed range is not
recommended. It may damage the switch and should
be avoided.
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.
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
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.
