There is a small spring in the end of the power unit spindle shaft. Be
careful not to lose this spring.
Note condition of 3-jaw clutch faces on power unit and screwdriver
mechanism. If they are badly rounded where the angular face meets the top
surface, or appear otherwise 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 there are no other apparent faults in the
mechanism, then proceed and be sure that the mechanism and all internal
areas are clean and free of chips or other foreign material and brush a thin
coat of PORTER-CABLE gear lubricant on the clutch elements and
surrounding areas. Reassemble the screwdriver mechanism onto the power
unit. Be sure the spring is on the spindle shaft. NOTE: The housing threads
are left-hand thread.
