Metal
For drilling with a metal
working drill bit.
For 6 mm or smaller
diameter screws.
For 4.8 mm or smaller
nominal diameter screws.
For 24 mm or smaller
diameters. (DS18DVB2)
For 18 mm or smaller

CAUTION
䡬 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.
䡬 When setting the shift knob to “HIGH” (high speed)
and the position of the cap 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
䡬 The selection examples shown in Table 5 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.
䡬 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.
NOTE
The use of the battery EB9H, EB926H, EB930H,
EB1222HL, EB1226HL, EB1230HL, EB1426H, EB1430H,
EB1826HL and EB1830HL 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
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. 9).
䡬 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 ect. (See Fig. 9).
Work Suggestions
Wood
Drilling Steel Use for drilling purpose.
Aluminum
Machine screw Use the bit or socket matching the screw diameter.
Driving
Wood screw Use after drilling a pilot hole.

䡬 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.
