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 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.
Check the remaining battery power by pressing the
remaining battery indicator switch at times.
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. 6) (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 hook
The hook is used to hang up the power tool to your
waist belt while working.

CAUTION:
When using the hook, hang up the power tool firmly
not to drop accidentally.
If the power tool is dropped, it may lead to an accident.
When carrying the power tool hooked to your waist
belt, do not fit any bit to the tip of power tool. If the
sharp bit such as drill is fitted to the power tool when
carrying it hooked to your waist belt, you will be
injured.
Install securely the hook. Unless the hook is securely
installed, it may cause an injury while being used.
(1) Removing the hook.
Remove the screws fixing the hook with Philips screw
driver. (Fig. 7)
(2) Replacing the hook and tightening the screws.
Install securely the hook in the groove of power tool
and tighten the screws to fix the hook firmly. (Fig. 8)
6. About Remaining Battery Indicator
When pressing the remaining battery indicator switch,
the remaining battery indicator lamp lights and the
battery remaining power can be checked. (Fig. 9)
When releasing your finger from the remaining
battery indicator switch, the remaining battery
indicator lamp goes off. The Table 4 shows the state
of remaining battery indicator lamp and the battery
remaining power.
Table 4
State of lamp Battery Remaining Power
The battery remaining power
is enough.
The battery remaining power
is a half.
The battery remaining power
is nearly empty.
Re-charge the battery soonest
possible.
As the remaining battery indicator shows somewhat
differently depending on ambient temperature and
battery characteristics, read it as a reference.
NOTE:
Do not give a strong shock to the switch panel or
break it. It may lead to a trouble.
To save the battery power consumption, the
remaining battery indicator lamp lights while pressing
the remaining battery indicator switch.
7. How to use the LED light
Every time you press the light switch on the switch
panel, the LED light lights or goes off. (Fig. 10)
To prevent the battery power consumption, turn off
the LED light frequently.
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.
