OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicable regulations.

WARNING: To reduce the risk of serious personal injury,
turn tool off and disconnect battery pack before making
any adjustments or removing/installing attachments or
accessories. An accidental start-up can cause injury.
Proper Hand Position (Fig. C)

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 Switch (Fig. A, D)
To turn the tool on, squeeze the trigger switch
the tool off, release the trigger switch. Your tool is equipped
with a brake. The chuck will stop when the trigger switch is
fully released.
The variable speed switch enables you to start the application at
a slow speed. The further 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, D)
A forward/reverse control button
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, depress the forward/reverse control button on
the left side of the tool. 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: 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.

Worklights (Fig. A)
There are three worklights
chuck 6 . The worklights are activated when the trigger switch
is depressed.
When the trigger is released, the worklight will stay illuminated
for up to 20 seconds. If the trigger switch remains depressed,
the worklights will remain on.
nOTE: The worklights are for lighting the immediate work
surface and are not intended to be used as a flashlight.
Quick-Release Chuck (Fig. A, E, F)

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.
nOTE: The chuck accepts 6.35 mm hex bit tips only. Using
25 mm bits allows better access in tight spaces.
Place the forward/reverse button
position or remove battery pack before changing accessories.
To install an accessory (Fig. E), push accessory to fully insert
into chuck . The chuck collar

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.

pointed straight at the fastener.
2. Press switch to start operation. Release the 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 recom-
mended could cause the fasteners to be overstressed, stripped
or damaged.
