DRIVING SELF-DRILLING/TAPPING SCREWS – MODELS 6640, 6645 These screws drill and tap their own hole as they are driven. This differs from self-tapping screws in that pre-drilled holes for tapping are not required. Drive these screws as follows: 1. Install proper nutsetter that fits screw to screwdriver. 2. Set screwdriver for correct rotation. 3. Start screwdriver and insert head of screw in nutsetter. 8 902387 - 10-31-01.qxd 2/12/02 3:30 PM Page 9 CAUTION: DO NOT EXERT PRESSURE ON SCREW WHILE DOING THIS. 4. Place end of screw in desired location and remove fingers. 5. Apply forward pressure to drive screw until depth stop rests on the surface of the work. The depth stop should be adjusted so the fastener head seats firmly on the work. Avoid seating the fastener too deep to prevent shearing off the head. TO REMOVE SCREWS – ALL MODELS 1. Install proper bit that fits screw. 2. Set screwdriver for reverse rotation. 3. Start screwdriver and place bit in screw. 4. Exert forward pressure to remove screw. MAINTENANCE KEEP TOOL CLEAN Periodically blow out all air passages with dry, compressed air. All plastic parts should be cleaned with soft damp cloth. NEVER use solvents, to clean plastic parts. They could possibly dissolve or otherwise damage the material. CAUTION: Wear safety glasses while performing this operation. FAILURE TO START Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line. CHECK CLUTCH CONDITION CAUTION: DISCONNECT TOOL FROM POWER SOURCE Periodically, depending on use, screwdriver clutch jaws should be inspected for wear. This may be done by removing the screwdriver mechanism housing (A), Fig. 5, from the power unit. NOTES: The clutch housing is attached to the power unit with left- hand threads. The depth stop assembly may be removed from the clutch housing to expose a set of wrenching “flats” (B), Fig. 5, on the clutch housing. These “flats” permit the use of a wrench to aid in clutch housing removal. B B A Fig. 5 9 902387 - 10-31-01.qxd 2/12/02 3:30 PM Page 10 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. BRUSH INSPECTION AND LUBRICATION For your continued safety and electrical protection, brush inspection and replacement on this tool should ONLY be performed by an AUTHORIZED PORTER-CABLE SERVICE STATION or a PORTER-CABLE/DELTA SERVICE CENTER. At approximately 100 hours of use, take or send your tool to your nearest Authorized Porter-Cable Service Station to be thoroughly cleaned and inspected; worn parts replaced, when necessary; relubricated with fresh lubricant, if required; reassembled with new brushes; and performance tested. Any loss of power before the above maintenance check may indicate the need for immediate servicing of your tool. DO NOT CONTINUE TO OPERATE TOOL UNDER THIS CONDITION. If proper operating voltage is present, return your tool to the Service Station for immediate service. SERVICE AND REPAIRS All quality tools will eventually require servicing or replacement of parts due to wear from normal use. These operations, including brush inspection and replacement, should ONLY be performed by either an AUTHORIZED PORTER-CABLE SERVICE STATION or a PORTER-CABLE/DELTA SERVICE CENTER. All repairs made by these agencies are fully guaranteed against defective material and workmanship. We cannot guarantee repairs made or attempted by anyone other than these agencies.
