CAUTION
●
The selection examples shown in Table 6 should
be considered as general standard. As different
types of tightening screws and different materials
to be tightened are used in actual works proper
adjustments are naturally necessary.
●
When using the hammer drill with a machine
screw at HIGH (high speed), a screw may damage
or a bit may loose due to the tightning torque is
too strong. Use the hammer drill at LOW (low
speed) when using a machine screw.
NOTE:
The use of the battery in a cold condition (below 0
degree Centigrade) can sometimes result in the
weakened tightening torque and reduced amount
of work. This, however, is a temporary
phenomenon, and returns to normal when the
battery warms up.
14. 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. 13) When releasing your finger from the
remaining battery indicator switch, the remaining
battery indicator lamp goes off. The Table 7 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.
15. 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. 14)
To prevent the battery power consumption, turn
off the LED light frequently.
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.
