● 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)
Guide sleeve
Driver bit
Hexagonal hole
in the socket
(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. Confi rm 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
and
marks are provided on the body.)

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.
○ 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
fi tting 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 fi rst 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 fi tted 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)
