CAUTION
●
The selection examples shown in Table 6 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.
●
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 BSL1415 and BSL1815 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, 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. 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).
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.
8. Confirm that the battery is mounted correctly
9. Check the rotational direction
The bit rotates clockwise (viewed from the rear
side) by pushing the R-side of the selector button.
