One-Shot Impact Function
This function helps adjust the screw head
flush to the material surface.
The driver rotates half round
∗
and auto-
matically stops each time the trigger switch
is depressed while tightening a screw.
The driver will give impact about 5 times
and automatically stop while tightening
a bolt even though the trigger switch is
depressed. The one-shot impact function
is also available in reverse rotation. The
impact force is set by the impact power
mode select and digital clutch settings.
NOTE:
∗ The one-shot impact function operates
after impact. Over-tightening may occur
when tightening screws into soft materi-
als as the tool does not impact.
