LED LIGHT (FIG. 7)
Your tool is equipped with the LED work light.
This provides additional light on the surface of
the workpiece for operation in lower-light areas.
The LED work light will automatically turn on
with a slight squeeze on the trigger switch
before the tool starts running. It will turn off
approximately 10 seconds after the trigger
switch is released.
a. 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.
b. The LED light will flash more slowly to indicate
that the battery pack charge is at low capacity.
Recharge the battery pack.
c. If the LED does not turn on when you start the
tool, or it turns off suddenly during operation,
please contact customer service or an
authorized service center for assistance.
MODE SELECTION (FIG. 8)
Your tool is equipped with a speed control
panel, located on the foot of the tool. It consists
of the drive-control button, the "A" button, and
LED indicators for working modes.
The drive-control button is used to select among
three modes with preset torque, rotation-speed
(RPM), and impact-speed (IPM) for intended
application. The modes 1, 2, and 3 are the only
modes where the speed is controlled by the
variable-speed trigger switch.
To select the drive control mode:
a. First, check the active mode. Either depress
and release the trigger switch or press the
drive control button (or the "A" button) directly
without touching the trigger switch. The
LED indicator below the mode number will
illuminate to indicate the active mode.
b. Press the drive-control button briefly (less
than 0.5 second) to cycle through three
modes. Each press changes one torque level.
See more details in the chart below.
"A" is a special mode, that is designed to be
used with reverse rotation for loosening the
bolts or nuts. Once the bolt or nut becomes
loose, the impact wrench will stop running
automatically to prevent bolt or nut from

falling away. The variable-speed trigger switch
functions only as an on/off switch.
NOTE:With the "A" mode selected and the
direction-of-rotation selector positioned to
FORWARD rotation, the tool functions as if the
mode 3 is active.
