䡬

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.

䡬

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 efficiently until
the battery runs down. However, it is difficult to
know the remaining battery power from the rotation
speed and the tool may stop suddenly during work.

䡬

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

and

marks

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

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.

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 fitting the
head of the screw.

CAUTION:

䡬

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.

䡬

Use the bit that fits 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 differ slightly according to the hardness
of wood or metal, the ambient temperature, the
charger properties, etc.)
