12. 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.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.

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.
13. 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. 13)
To prevent the battery power consumption, turn off
the LED light frequently.

Light switch
CAUTION
Do not expose directly your eye to the light by
looking into the light.
If your eye is continuously exposed to the light,
your eye will be hurt.
NOTE:
To prevent the battery power consumption caused
by forgetting to turn off the LED light, the light goes
off automatically in about 15 minutes.

OPERATIONAL CAUTIONS

1. Resting the unit after continuous work
After use for continuous bolt-tightening work, rest
the unit for 15 minutes or so when replacing the
battery. The temperature of the motor, switch, etc.,
will rise if the work is started again immediately after
battery replacement, eventually resulting in burnout.
CAUTION
Do not touch the metal parts, as it gets very hot
during continuous work.
2. Cautions on use of the speed control switch
This switch has a built-in, electronic circuit which
steplessly varies the 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. Use a tightening time suitable for the screw
The appropriate torque for a screw differs according
to the material and size of the screw, and the material
being screwed etc., so please use a tightening time
suitable for the screw. In particular, if a long
tightening time is used in the case of screws smaller
than 5/16" (8 mm), there is a danger of the screw
breaking, so please confirm the tightening time and
the tightening torque beforehand.
