Remove exhausted batteries from the hook
immediately.
● Do not discard batteries together with normal
trash and do not throw batteries into fire.
● Store batteries out of the reach of children.
● Use batteries correctly in accordance with the
battery specifications and indications.
2. Installing the bit
Always follow the following procedure to install
driver bit. (Fig. 13)
(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.
3. Removing the bit
Please do the opposite point on the method of installing bit.
4. Confirm that the battery is mounted correctly.
5. 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. 14).
(The
L and R marks are engraved on the 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.
6. Switch operation
⅜ When the trigger switch is depressed, the tool rotates. When the trigger is released, the
tool stops.
⅜ 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.
7. 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.
