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.

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. A, D)
Your tool is equipped with a mode selector
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 1 .
Precision Drive (Fig. D)
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

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.
- socket size: Failure to use the correct socket 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.
