When the shift knob is set to "LOW", the drill rotates
at a low speed. When 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 3 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 tightening torque is too strong. Use
the driver drill at LOW (low speed) when using a
machine screw.
NOTE:
The use of the battery BCL1015 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. Mounting and dismounting of the bit
(1) Mounting the bit
After inserting a driver bit, etc. into the keyless drill
chuck, firmly grasp the ring and tighten the sleeve by
turning it toward the right (in the clockwise direction
as viewed from the front) (See Fig. 10).

Use for drilling purpose.
Use the bit or socket matching the screw diameter.
Use after drilling a pilot hole.

For 4 mm or smaller diameter

screws.
For 5.8 mm or smaller nominal
1 –
diameter screws.
For 21 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 "21", 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).
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.
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 2.
Suggestions
For 6 mm or smaller
diameter screws.
For 3.8 mm or smaller
nominal diameter screws.
For 12 mm or smaller
diameters.
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
Firmly grasp the ring and loosen the sleeve by turning
it toward the left (in the counter-clockwise direction
as viewed from the front) (See Fig. 10).
CAUTION
When it is no longer possible to loosen the sleeve, use a
vise or similar instrument to secure the bit. Set the
clutch mode between 1 and 13, and then turn the
sleeve to the loose side (left side) while operating the
clutch. It should be easy now to loosen the sleeve.
7. Confirm that the battery is mounted correctly
8. Check the rotational direction
The bit rotates clockwise (viewed from the rear side)
by pushing the R-side of the selector button.
The L-side of the selector button is pushed to turn the
bit counterclockwise (See Fig. 6) (The
marks are provided on the body).
9. Switch operation
When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
