Remove exhausted batteries from the hook
immediately.
Do not discard batteries together with normal trash
and do not throw batteries into fire.

2. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the push button.
The L-side of the push button is pushed to turn the bit
counterclockwise. (See Fig. 12) (The
are provided on the body.)

Push
CAUTION:
The push button cannot be switched while the impact
driver is turning. To switch the push button, stop the
impact driver, then set the push button.
3. Switch operation
When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
The rotational speed can be controlled by varying the
amount that the trigger switch is pulled. Speed is low
when the trigger switch is pulled slightly and increases
as the trigger switch is pulled more.
4. Tightening and loosening screws
Install the bit that matches the screw, line up the bit
in the grooves of the head of the screw, then tighten
it.
Push the impact driver just enough to keep the bit
fitting the head of the screw.
CAUTION:
Applying the impact driver for too long tightens the
screw too much and can break it.
Tightening a screw with the impact driver at an angle
to that screw can damage the head of the screw and
the proper force will not be transmitted to the screw.
Tighten with this impact driver lined up straight with
the screw.
5. Number of screws tightenings possible
