WARNING!
Do not change the working mode while the
tool is running. Sudden change of torque
may cause the loss of control causing possible
injury or damage to the tool or workpiece.
NOTE
The variety of wood density and metal
material may affect the final outcome. The
user should select appropriate mode based
on the application.
NOTE
The LED indicator will turn off approximately
1min after the trigger switch is released.
NOTE
When the tool is next turned on, the working
mode will revert to the previous setting.
Switching on the power tool (see
figure I)
■ To switch the power tool on:
Press the trigger switch 2.
The variable-speed trigger switch delivers
higher speed with increased trigger pressure
and lower speed with decreased trigger
pressure.
■ To switch the power tool off:
Release the trigger switch.
LED light (see figure J)
■ The LED light will automatically turn on
with a slight squeeze on the variable-
speed trigger switch before the tool starts
running and will turn off approximately 10
seconds after the variable speed trigger
switch is released.
■ The LED light will rapidly flash when
the tool and/or battery pack becomes
overloaded or too hot, and the internal
sensors will turn the tool off. Rest the tool
for a while or place the tool and battery
pack separately under air flow to cool
them.
■ The LED light will flash more slowly to
indicate that the battery is at low-battery
capacity. Recharge the battery pack.
■ If the LED fails to light up when you switch
on the tool, or it turns off suddenly during
your operation, it may be caused by the
internal communication error. Please
contact customer service or an authorized
service center for assistance.

Tighten and loosen nuts and
bolts (see figure K)
To tighten nuts and bolts
Use the hex socket that matches the nut or
bolt. Select a proper working mode or "A"
mode depending on the type or size of the
bolt and nut. Before starting your job, always
perform a test operation to determine the
proper fastening time for your bolt or nut.
It is advisable to perform a trial run on a
scrap material to determine the best mode
selection.
■ Set the direction preselector switch to
forward setting.
■ Hold the tool firmly and place the socket
over the bolt or nut. Ensure that full length
of the bolt head or nut is fully engaged
into socket.
■ Depress the variable-speed trigger switch
to turn the impact wrench on. Start slowly,
increasing the speed as the nut or bolt
runs downs. Set the nut or bolt snugly by
slowing the tool to a stop. If this procedure
is not followed, the tool will have a
tendency to torque or twist in your hand
when the nut or bolt seats.
■ Fasten the bolt or nut to the proper torque.
■ After fastening, always check the torque
with a torque wrench. If the fasteners are
too tight, reduce the impacting time. If
they are not tight enough, increase the
impacting time.
NOTICE:
■ Hold the tool straight along the axis of the
bolt or nut.
■ Excessive fastening torque may damage
the bolt/nut or socket.
To loosen nuts and bolts
Use either mode 1, 2, 3 or "A" mode to loosen
nuts and bolts depending on the application.
When working overhead or working on car
tires, to prevent the loosened fasteners from
falling to the ground or into a tight space, it is
recommended to use the "A" mode to do this
job.
■ Set the direction preselector switch to
reverse setting.
■ Hold the tool firmly and place the socket
over the bolt or nut. Ensure that full length
