12.About RemainingBatteryIndicator
When pressing the remaining battery indicator
switch, the remaining battery indicator lamp lights
and the battery remaining power can be checked.
(Fig.12) When releasing your finger from the
remaining battery indicator switch, the remaining
battery indicator lamp goes off. The table 5 shows
the state of remaining battery indicator lamp and
the battery remaining power.

NOTE:
O Do not give a strong shock to the switch panel or
break it.It may lead to atrouble.
O To save the battery power consumption, the
remaining battery indicator lamp lights while
pressingthe remaining battery indicator switch.
13. How to use the LEDlight
Everytime you pressthe light switch on the switch
panel,the LEDlight lights or goes off. (Fig. 13)
To preventthe batterypower consumption, turn off
the LEDlight frequently.

CAUTION
Do not expose directlyyour eye to the light by
lookingintothe light.
If youreye is continuously exposedto the light,
youreyewill be hurt.
NOTE:
To preventthe battery power consumption caused
byforgetting to turn off the LEDlight, the light goes
off automatically in about 15 minutes.
OPERATIONAL CAUTIONS
1. Restingthe unit after continuouswork
After use for continuous bolt-tightening work, rest
the unit for 15 minutes or so when replacing the
battery. Thetemperature of the motor, switch, etc.,
will rise if the work isstartedagainimmediatelyafter
batteryreplacement, e ventually resultingin burnout.
Ak CAUTION
Do not touchthe metal parts,as it getsvery hot
duringcontinuous work.
2. Cautionson useof the speedcontrol switch
This switch has a built-in, electronic circuit which
steplesslyvariesthe rotation speed. Consequently,
when the switch trigger is pulled only slightly (low
speed rotation) and the motor is stopped while
continuously driving in screws,the components of
the electronic circuit parts may overheat and be
damaged.
3. Usea tightening time suitablefor the screw
The appropriatetorque for a screwdiffers according
to the materialandsizeof the screw,andthe material
being screwedetc., so pleaseuse atightening time
suitable for the screw. In particular, if a long
tightening time is usedinthe caseof screwssmaller
than 5/16" (8 mm), there is a danger of the screw
breaking,so pleaseconfirm the tightening time and
the tightening torque beforehand.
