7. How to select tightening torque and rotational speed
Use
Machine screw
Driving
Wood screw
Brick
Drilling
Wood
Metal
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 impact driver 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 impact driver 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.
8. 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 with 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 with 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 using.
(1) Removing the hook.
Remove the screws fixing the hook with screw driver.
(Fig. 10)
(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. 11)
9. 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 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.
10. 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.
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.
