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.
(2)Dismounting the bit
Firmly grasp the ring and loosen the sleeve by turning it toward the left (in the
Tighten
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.

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
