CAUTION
The selection examples shown in Table 2 should
be utilized as a 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.
6. Mounting and dismounting of the bit.
(1) 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. 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)
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 11and then turn

For drilling with a metal
working drill bit.
The usable scope for various types of work based
on the mechanical structure of this unit is shown
in Table 1.
Suggestions
the sleeve to the loose side (left side) while operating
the clutch. It should be easy now to loosen the
sleeve.
NOTE
There is a plus driver bit on side of the main unit.
The bit can be removed by pulling it forward. After
using the bit, make sure to firmly attach it to the
main body again.
7. Confirm that the battery is mounted correctly.
8. Check the rotation 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
marks are provided on the body.)
9. Switch operation
When the trigger switch is pulled, 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 peep sound may be produced when the motor
is about to rotate; This is only a noise, not a machine
failure.
