8. Selecting the driver bit
Screw heads or bits will be damaged unless a bit appropriate for the screw diameter is
employed to drive in the screws.
9. Mounting and dismounting of the bit.
For keyless chuck
(1) Mounting the bit
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. 4)
If the sleeve becomes loose during operation, tighten it further. The tightening force
becomes stronger when the sleeve is tightened.
(2) Dismounting the bit
Firmly grasp the ring and loosen the sleeve by turning it toward the left (in the
counterclockwise direction as viewed from the front). (See Fig. 4)
NOTE:
When the sleeve does not become loose any further, fix the side handle to the sleeve.
Then, strike the grip of the side handle to the left in order to loosen the sleeve, while
holding the ring by hand. (Fig. 5)

chuck by each of the three holes in turn.
