CAUTION
● The selection examples shown in Table 6 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 hammer 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 hammer drill at LOW (low
speed) when using a machine screw.
NOTE
The use of the battery BSL18 series 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.

7. Mounting and dismounting of the bit
(1) After inserting a driver bit, etc. into the keyless drill
chuck, fi rmly 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
Loosen the sleeve by turning it toward the left (in the
counter-clockwise direction as viewed from the front).
