(2) When using this unit as a drill, align the clutch dial drill
mark "
" with the triangle mark on the outer body.
CAUTION
○ The clutch dial cannot be set between the numerals "1, 5,
9 ... 21" or the black dots.
○ Do not use with the clutch dial numeral between "21" and
the black line at the middle of the drill mark. Doing so may
cause damage (See Fig. 6).
6. Tightening torque adjustment
(1) Tightening torque
Tightening torque should correspond in its intensity to
the screw diameter. When too strong torque is used,
the screw head may be broken or be injured. Be sure
to adjust the clutch dial position according to the screw
diameter.
(2) Tightening torque indication (See Fig. 5)
The tightening torque diff ers depending on the type of
screw and the material being tightened.
The unit indicates the tightening torque with the numbers
"1, 5, 9 ... 21" on the clutch dial, and a black dots. The
tightening toque at position "1" is the weakest and the
torque is strongest at the highest number.
(3) Adjusting the tightening torque (See Fig. 5)
Rotate the clutch dial and line up the numbers "1, 5, 9 ...
21" on the clutch dial, or the dots, with the triangle mark
on the outer body. Adjust the clutch dial in the weak or the
strong torque direction according to the torque you need.
CAUTION
○ The motor rotation may be locked to cease while the unit
is used as drill. While operating the driver drill, take care
not to lock the motor.

CAUTION:
○ The selection examples shown in Table 3 should be
considered as general standard. As diff erent types of
tightening screws and diff erent materials to be tightened
are used in actual works proper adjustments are naturally
necessary.
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.

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

○ 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.
○ Too long hammering may cause the screw broken due to
excessive tightening.
7. 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. 7) (The
provided on the body).
8. Switch operation
○ When the trigger switch is depressed, the tool rotates.
When the trigger is released, the tool stops.
○ The rotational speed of the drill can be controlled by
varying the amount that the trigger switch is pulled.
Speed is low when the trigger switch is pulled slightly and
increases as the trigger switch is pulled more.
NOTE
○ A buzzing noise is produced when the motor is about to
rotate; This is only a noise, not a machine failure.
9. Using the 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. 8)
CAUTION:
Do not look directly into the light. Such actions could
result in eye injury.
10. 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.

12. Battery Level Warning Lamp
The battery level can be checked by pulling the trigger
switch while the power tool is in a no-load state. The
battery level warning lamp lights when the battery power
is very low. If this happens, charge the battery. (Fig. 9)
NOTE:
○ The level at which the battery level warning lamp lights
may vary due to the ambient temperature, characteristics
of the battery, etc. and is intended only as a guide.
○ The battery level warning lamp may light when the power
tool is overloaded. This does not mean that the battery
power is very low.
Be sure to check the battery level while the tool is in a
no-load state.
MAINTENANCE AND INSPECTION
1. Inspecting the tool
Since use of as dull tool will degrade effi ciency and cause
possible motor malfunction, sharpen or replace the tool
as soon as abrasion is noted.
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that
they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could
result in serious hazard.
