CAUTION
○ When changing the rotational speed with the shift knob,
confi rm 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 clutch dial is "17" or "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).

CAUTION
○ The selection examples shown in Table 5 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.
○ 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.
6. Mounting and dismounting of the bit
(1) After inserting a driver bit, etc. into the keyless drill chuck,
fi rmly grasp the ring and tighten the sleeve by turning it
toward the right (in the clockwise direction as viewed
from the front) (See Fig. 8).
○ 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. 8).
7. Confi rm 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. 9) (The
are provided on the body).

○ 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 4.
Suggestions
Rotating speed selection (Position of the shift knob)
9. 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.
10. Using the bit holder
CAUTION
○ Stow the bit in the specifi ed location on the tool. If the tool
is used with the bit stowed improperly, the bit may fall and
cause bodily injury.
○ Do not stow bits that are of a diff erent length, gauge or
dimension than the plus driver bit (65 mm long) included
in the STANDARD ACCESSORIES.
The bit may fall and cause bodily injury.
(1) Removing the bit
Securely hold the main unit and pull out the bit by holding
the tip with your thumb (Fig. 10).
(2) Installing the Bit
Install the bit with steps opposite of when removing.
Insert the bit so that the right and left sides are equal, as
shown in Fig. 11.
