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 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 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.
6. 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.

Suggestions
(1) Removing the hook.
Remove the screws fixing the hook with screw driver.
(Fig. 11)
(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. 12)
7. How to use the LED light
Pull the trigger switch to light up the light. The light
keeps on lighting while the trigger switch is being
pulled. The light goes out after releasing the trigger
switch. (Fig. 13)
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.
8. 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. 14)
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 ect. (See Fig. 14)
HIGH (High speed)
For 6 mm or smaller
diameter screws.
For 4.8 mm or smaller
nominal diameter screws.
For 24 mm or smaller
diameters. (DS18DSAL)
For 18 mm or smaller
diameters. (DS14DSAL)
