CAUTION
○ The selection examples shown in Table 4 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
<For double sleeve chuck>
(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. 9).
○ 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. 9).

For 24 mm or smaller diameters.
(DS18DVF3)
For 12 mm or smaller diameters.
(DS14DVF3/DS12DVF3/DS9DVF3)
<For single sleeve chuck>
(1) Mounting the bit
Loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front)
to open the clip on the keyless chuck. After inserting a
driver bit, etc., into the keyless drill chuck, and tighten
the sleeve by turning it toward the right (in the clockwise
direction as viewed from the front) (See Fig. 10).
○ 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
Loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front),
and then take out the bit, etc (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 11, and then turn the sleeve
to the loose side (left side) while operating the clutch. It
should be easy now to loosen the sleeve.
