Always follow the following procedure to
install driver bit. (Fig. 5)
(1) Pull the guide sleeve back.
(2) Insert the bit into the hexagonal hole in the
anvil.
(3) Release the guide sleeve and it returns to
its origianl position.
CAUTION
If the guide sleeve does not return to its original position, then the bit is not installed
properly.
2. Removing the bit
Please do the opposite point on the method of installing bit.
3. Confirm that the battery is mounted correctly.
4. 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. 6).
(The
L
and
R

body.)
CAUTION
The push button can not be switched while the impact driver is turning. To switch the
push button, stop the impact driver, then set the push button.
5. Switch operation
䡬
When the trigger switch is depressed, the tool rotates. When the trigger is released, the
tool stops.
䡬
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.
NOTE
A buzzing noise is produced when the motor is about to rotate; this is only a noise, not
a machine failure.
