Variable Speed Trigger Switch (Fig. 1)
To turn the tool on, squeeze the trigger switch (A).
To turn the tool off, release the trigger switch. Your
tool is equipped with a brake. The tool 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. 1)
A forward/reverse control button (B) determines the
direction of the tool and also serves as a lock-off
button.
To select forward rotation, release the trigger switch
(A) and depress the forward/reverse control button
(B) on the right side of the tool.
To select reverse, release the trigger switch (A) and
depress the forward/reverse control button (B) on
the left side of the tool. The centre position of the
control button locks the trigger switch 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. 1)
There are three worklights (G) located around the
6.35 mm (1/4") hex chuck (D). 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.
NOTE: The worklights are for lighting the immediate
work surface and are not intended to be used as a
flashlight.
Mode Selector (Fig. 1, 4)
Your tool is equipped with a mode selector (K)
which allows you to select one of three modes.
Select the mode based on the application and
control the speed of the tool using the variable
speed trigger switch (A).
Precision Drive (Fig. 4)
In addition to normal impacting modes, this tool
features the Precision Drive mode which enables
greater control in lighter applications to avoid
damage to materials or fasteners. It is ideal for
light applications such as cabinet hinge screws or
machine screws. Precision Drive mode will work as
a screwdriver in light applications, before hesitating
as the screw head reaches the work piece, and
then (if required) start a slow controlled impact to
ensure the head ends perfectly flush.
NOTE: This mode is for light duty screwdriving
applications. If the tool will not drive a fastener in
Precision Mode, please select mode 2 which will
give the additional power required.
Mode 1 Precision Drive
Mode 2 Normal Impacting
Mode 3 High Speed Impacting rpm
Quick-Release Chuck (Fig. 2, 5, 6)
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 1/4" (6.35 mm) hex
accessories only.
