Proper Hand Position (Fig. D)

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

Variable Speed Trigger and Forward/
Reverse Control Button (Fig. A)
The tool is turned ON and OFF by pulling and releasing the
variable speed trigger 1 . The farther the trigger is pulled,
the higher the speed of the tool.
A forward/reverse control button
direction of the tool and also serves as a lock-off button.
• To select forward rotation, release the trigger and
depress the forward/reverse control button on the right
side of the tool.
• To select reverse, depress the forward/reverse control
button on the left side of the tool.
nOTE: 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: 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.

the trigger switch is squeezed.
nOTE: The worklight is for lighting the immediate work
surface and is not intended to be used as a flashlight.

Usage (Fig. A)

WARNING: Use only impact accessories. Non-impact
accessories may break and cause a hazardous
condition. Inspect accessory prior to use to ensure that
it con tains no cracks.

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.
