6. How to select tightening torque and rotational speed
Use Cap Position
Rotating speed selection (Position of the shift knob)
LOW (Low speed) HIGH (High speed)
Machine screw 1 – 22
For 4 mm or smaller
diameter screws.
Driving
Wood screw 1 –
For 6.8 mm or smaller
nominal diameter screws.
Brick
For 13 mm or smaller
diameters.
Drilling
Wood
For 36 mm or smaller
diameters.
Metal
For drilling with a metal
working drill bit.
Table 5
For 6 mm or smaller
diameter screws.
For 3.8 mm or smaller
nominal diameter screws.
For 10 mm or smaller
diameters.
For 18 mm or smaller
diameters.
CAUTION
⅜ The selection examples shown in Table 5 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.
⅜ 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 Li-ion 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.
7. Using the hook
The hook is used to hang up the power tool to your
waist belt while working.
CAUTION:
⅜ 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.
⅜ 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.
⅜ Install securely the hook. Unless the hook is securely
installed, it may cause an injury while using.

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.
(1) Removing the hook.
Remove the screws fixing the hook with Philips screw
driver. (Fig. 9)
(2)
Replacing the hook and tightening the screws.

and tighten the screws to fix the hook firmly. (Fig. 10)
8. 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.11)
When releasing your finger from the remaining battery
indicator switch, the remaining battery indicator lamp
goes off. The table 6 shows the state of remaining
battery indicator lamp and the battery remaining
power.
⅜ If the motor is locked, immediately turn the power
off. If the motor is locked for a while, the motor or
battery may be burnt.
