●
If the battery charger does not work while the
battery is mounted correctly, it is probable that the
battery or charger is malfunctioning. Take it to your
authorized Service Center.
BEFORE USE
Check the work area to make sure that it is clear of debris
and clutter.
Clear the area of unnecessary personnel. Ensure that
lighting and ventilation is adequate.
OPERATION
1. Installing the bit
Always follow the following procedure to install
driver bit. (Fig. 5)
(1) Pull the guide sleeve forward.
(2) Insert the bit into the hexagonal hole in the socket.
(3) Release the guide sleeve and it returns to its original
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 selector button.
The L-side of the selector button is pushed to turn
the bit counterclockwise (See Fig. 6).
(The
L
and
R
marks are provided on the body.)

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.
䡬
When releasing the trigger of the switch, the brake
will be applied for immediate stopping.
NOTE
A buzzing noise is produced when the motor is about
to rotate. This is only a noise, not a machine failure.
6. 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.
7. Tightening and loosening bolts
A hex. socket matching the bolt or nut must first be
selected. Then mount the socket on the anvil, and
grip the nut to be tightened with the hex. socket.
Holding the wrench in line with the bolt, press the
power switch to impact the nut for several seconds.
If the nut is only loosely fitted to the bolt, the bolt
may turn with the nut, therefore mistaking proper
tightening. In this case, stop impact on the nut and
hold the bolt head with a wrench before restarting
impact, or manually tighten the bolt and nut to
prevent them slipping.
8. Using the light
Pull the trigger switch to light up the light. The light
keeps on lighting while the trigger switch is being
pulled. The light goes out after releasing the trigger
switch. (Fig. 7)
