3. Change rotation speed
Operate the shift knob to change the rotational speed.
Move the shift knob in the direction of the arrow (see
Figs. 7 and 8).
When the shift knob is set to "LOW", the drill rotates at a
low speed.!»en set to "HIGH", the drill rotates at a high speed.
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.

CAUTION:
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.
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 BSL1430/BSL1415 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.
The use of the battery BSL1415 is recommended for
light work.

Use for drilling purpose.
Use the bit or socket matching the screw diameter.
Use after drilling a pilot hole.
Table 5
Rotating speed selection (Position of the shift knob)
Clutch Position
LOW (Low speed)
For 6 mm or smaller diameter
1 – 22
screws.
For 6.8 mm or smaller nominal
1 –
diameter screws.
For 36 mm or smaller
diameters.
For drilling with a metal
working drill bit.
When setting the shift knob to "HIGH" (high speed)
and the position of the clutch dial is "17" or "22", it
may happen that the clutch is not engaged and that
the motor is locked. In such a case, please set the
shift knob to "LOW" (low speed).
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.
Be sure to turn the shift knob.

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.
(1) Removing the hook.
Remove the screws fixing the hook with Philips screw
driver. (Fig. 9)
(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. 10)
HIGH (High speed)
For 4 mm or smaller
diameter screws.
For 3.8 mm or smaller
nominal diameter screws.
For 18 mm or smaller
diameters.
