How to switch over the Power mode (P) or Save
mode (S)
To set to the Power mode (P), slide the lever on the
side of handle to the lower side, and to set to the
Save mode (S), slide the lever to the upper side.
(Fig. 9)
CAUTION:
When changing the rotational speed with the shift
knob, confirm that the switch is off.
Changing the speed while the motor is rotating will
damage the gears.
When setting the shift knob to "HIGH" (high speed)
and the position of the cap is bitween "16" and "22",
it may happen that the clutch does not engaged and
that the motor is locked. In such a case, please set the
shift knob to "LOW" (low speed).
4. The scope and suggestions for uses
The usable scope for various types of work based on the mechanical structure of this unit is shown in Table 7.

CAUTION:
The selection examples shown in Table 8 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 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 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.

For drilling with a metal
working drill bit
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.
In the work of the save mode (S), avoid the continuous
screw-tightening as temperature of electronic
components of the converter switch increases.
To extend the lifetime, the lithium-ion battery equips
with the protection function to stop the output.
Therefore, if the tool is overloaded, the motor may
stop. However, this is not the trouble but the result of
protection function. In this case, release the switch of
tool and eliminate the causes of overloading.
Suggestions
For 6 mm or smaller
diameter screws
For 4.8 mm or smaller
nominal diameter screws
For 24 mm or smaller
diameters
6. Mounting and dismounting of the bit
(1) Mounting the bit
Loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front)
to open the clip on the keyless chuck. After inserting
a driver bit, etc., into the keyless drill chuck, and
tighten the sleeve by turning it toward the right (in
the clockwise direction as viewed from the front).
(See Fig. 10)
If the sleeve becomes loose during operation, tighten
it further.
The tightening force becomes stronger when the
sleeve is tightened additionally.
(2) Dismounting the bit
Loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front),
and then take out the bit, etc. (See Fig. 10)
