Elapsed time after switching on
○ The tool may not return to the initial status from the
striking operation.
When the bit or socket is removed from the screw or bolt
while the switch is being pulled, the tool may continue the
striking operation.
To return to the initial status, turn off the switch and then
start the next operation.
○ Motor rotation speed does not decrease even when the
remaining battery power becomes low.
Since this tool adopts the constant-speed control, the
rotation speed is almost unchanged even when the
remaining amount of the battery becomes low. This
allows users to operate the tool effi ciently until the battery
runs down. However, it is diffi cult to know the remaining
battery power from the rotation speed and the tool may
stop suddenly during work.
○ The tool stops automatically when the electronic clutch is
actuated.
Quiet screw tightening can be performed without clutch
sound generated by the mechanical type.
The tool stops automatically when the clutch is actuated.
If you continue to use the tool, turn off the switch once
and turn it on again. When the tool does not operate even
without load, the remaining amount of the battery is low.
In this case, recharge the battery immediately.
3. 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. 7) (The
are provided on the body.)

CAUTION:
The push button can not be switched while the tool is
turning. To switch the push button, stop the tool, then set
the push button.
4. 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.
5. 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. 8)
CAUTION:
Do not expose directly your eyes to the light by looking
into the light.
If your eyes are continuously exposed to the light, your
eyes will be hurt.
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 tool just enough to keep the bit fi tting the head
of the screw.
CAUTION:
○ Applying the tool for too long tightens the screw too much
and can break it.
Tightening a screw with the tool 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 tool lined up straight with the screw.
○ Use the bit that fi ts the cross recess on the screw head.
Make sure to use an appropriate bit especially when
tightening self drilling screws since using an inappropriate
bit can topple the screws.
7. Work amount possible with one charging
The following table shows the approximate amount of
work to be carried out by the tool with one charging.
(The number of screws tightened and that of boring
operations diff er slightly according to the hardness of
wood or metal, the ambient temperature, the charger
properties, etc.)
