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 etc. (See Fig. 14)

the keyless chuck is prevented and is not a malfunction.

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
