L120-10 through 40 Drive Sleeve & Housing Cover Parts Breakdown
Counterclockwise rotation of the Declutch Lever  (#9) causes the declutch actuator to lift the clutch sleeve out of engagement with the worm gear. Drive lugs on top of the clutch sleeve engage  matching lugs in the Handwheel Adapter (#26) and then latches engage the clutch sleeve in this position. The actuator is now in the handwheel driving option. Energizing the motor at this point will cause the latches to drop out and the spring loaded clutch sleeve re-engages with the lugs on the worm gear. The actuator is once more in motor operation.


NOTE 1: The shift from manual operation to motor operation is automatic and does not require external position of the declutch shaft.
NOTE 2: If the declutch mechanism does not engage, rotate handwheel approximately 30-45° and attempt manual engagement. There is a chance that the lugs on the clutch sleeve (#19) and handwheel adapter (#26) are not correctly aligned.
