MAINTENANCE
CHECK CLUTCH CONDITION
Periodically, inspect the screwdriver clutch jaws for wear by removing the screwdriver
mechanism housing (A) Fig. 4 from the power unit.
The clutch housing is attached to the power unit with
left-hand
threads. The depth
stop assembly may be removed from the clutch housing by pulling it straight off.
Remove the clutch housing by turning the clutch housing clockwise.
Be careful not to lose the small spring that is in the end of the power unit spindle
shaft.
Note the condition of the 3-jaw clutch faces on the power unit and screwdriver mechanism. If
they are badly rounded where the angular face meets the top surface, or appear worn or faulty,
or if the clutch elements are not securely held in place on their respective shafts by the snap
rings, return the entire tool to your AUTHORIZED PORTER-CABLE SERVICE STATION for service.
If the jaws are not seriously worn and no other apparent faults are found, clean the mechanism
and all internal areas of chips or other foreign matter and brush a thin coat of PORTER-CABLE
gear lubricant on the clutch elements and surrounding areas. Attach the screwdriver mechanism
to the power unit, being sure that the spring is in the spindle shaft.
The housing threads are left-hand thread.
