(2) Rotation only (Fig. 7)
Set the change lever to "rotation only" ( mark). The pin of the change lever moves the lock plate
forward, and the clutch moves forward at the back end of the lock plate. Engagement is released
between the clutch and claws of the reciprocating bearing (at A in the figure). As a result, no rotation is
transmitted to the reciprocating bearing and hammering stops. Conversely, for the "rotation only"
function, the pinion sleeve engages with the second pinion (at B in the figure) to transmit rotation to the
pinion sleeve.
(3) Hammering only (Fig. 8)
Set the change lever to "hammering only" ( mark). The pin of the change lever moves the second
pinion to the motor side. Engagement is released between the pinion sleeve and second pinion, so that
no rotation is transmitted (at B in the figure). The lock plate is moved to the motor side by spring (B) and
engages with the locking claw of the second pinion to lock cylinder rotation (at C in the figure).
Conversely, for the "hammering only" function, the clutch engages with the reciprocating bearing (at A in
the figure).
