Ignoring this warning may lead to serious personal injury or even death! -8- H5570 18 Gauge Finish Angle Nailer Replacing Pistons/O-Rings If you use your nailer day in and day out, Grizzly offers repair pistons as cheap insurance against wasted down time and lost profits in the event that a piston or piston shaft becomes worn out. Always disconnect air from nailer whenever servicing! During maintenance, a nailer connected to air may fire accidentally, causing serious personal injury! To replace a piston: 1. Disconnect the nailer from the air supply! 2. Remove all nails from the magazine cartridge. 3. Remove the 4 cap screws on the back of the nailer, near the exhaust port. 4. Remove the rear cap as shown in Figure 8. Figure 8. Removing rear cap. H5570 18 Gauge Finish Angle Nailer 5. The top of the piston should now be visible inside the cylinder, which is housed in the head of the nailer. 6. Open the magazine. 7. Watch the discharge area and push the top of the piston with your finger. You will see the piston shaft slide down the discharge area. 8. With a long flathead screwdriver or similarly shaped tool, push the piston shaft back inside the nailer until you can grip the piston head and remove it from the cylinder. (Be careful not to scratch the discharge area when pushing the piston shaft with the screwdriver.) 9. Place a new O-ring on the new piston and apply a thin film of the nailer lubricating oil on the O-ring. 10. Insert the new piston in the cylinder. Make sure that the grooves on the piston shaft line up with those on the guide at the bottom of the cylinder. The new piston should easily slide into the cylinder. DO NOT force the piston into the cylinder! If the piston is not easily inserted, double-check the alignment of the piston shaft with the grooves on the guide. 11. After the piston is inserted correctly, close the magazine. Replace the rear cap assembly and tighten the 4 cap screws. 12. For more assistance, or to install a complete O-ring set, refer to the appropriate breakdown diagram in the back of this manual. -9 -10- H5570 18 Gauge Finish Angle Nailer H5570 PART BREAKDOWN REF PART # DESCRIPTION REF PART # DESCRIPTION 01 PSB113M BTN CAP SCR M5-.8 X 11 02 PH5570002 EXHAUST COVER 03 PH5570003 SEAL 04 PSB15M CAP SCREW M5-.8 X20 05 PSS08M SET SCREW M4-.7 X 5 06 PH5570006 CAP 07 PH5570007 PISTON STOPPER 08 PH5570008 O RING 09 PH5570009 COLLAR 10 PH5570010 O RING 11 PH5570011 SPRING 12 PH5570012 PISTON HEAD VALVE 13 PH5570013 STOPPER 14 PH5570014 O RING 15 PH5570015 O RING 16A PH5570016A DRIVER ASSEMBLY 17 PH5570017 CYLINDER 18 PH5570018 O RING 19 PH5570019 BUMPER 20 PH5570020 GASKET 21 PH5570021 O RING 22 PH5570022 BODY 23 PSB24M CAP SCREW M5-.8 X 16 24 PH5570024 1/4" NPT MALE CONNECT 25 PH5570025 DRIVER GUIDE WASHER 26 PH5570026 PIN 27 PH5570027 SPRING 28 PH5570028 GUIDE SAFETY LEVER 29A PH5570029A SAFETY LEVER 36 PRP42M ROLLED PIN M3 X 20 37A PH5570037A LATCH 38 PH5570038 DRIVER GUIDE COVER 39 PH5570039 PIN 39-1 PEC01M E RING 3MM 40 PSB33M CAP SCREW M5-.8 X 12 41 PH5570041 DRIVER GUIDE 43 PSB97M CAP SCREW M5-.8 X 6 43-1 PLW01M LOCK WASHER 5MM 44 PH5570044 PIN 45 PH5570045 MAGAZINE 46 PH5570046 NAIL GUIDE LINER 47 PH5570047 UPPER COVER 48 PH5570048 SPIRAL SPRING 49 PH5570049 COVER 49-1 PH5570049-1 ROLLER 50 PH5570050 PUSHER 51 PH5570051 FOLLOWER SEAT 52 PH5570052 SPECIAL SCR M4-.7 X 6 53 PH5570053 SPRING 54 PH5570054 FOLLOWER BODY 55 PH5570055 SPECIAL SCR M4-.7 X 6 56 PS09M PHLP HD SCR M5-.8 X 10 57 PH5570057 SET PLATE 58 PH5570058 BRACKET 58-1 PSB18M CAP SCREW M4-.7 X 8 59 PLN01M LOCK NUT M4-.7 60 PH5570060 TAIL COVER 61 PHTEK26M TAP SCREW M5-.8 X 10 62 PH5570062 POSITIONING PLATE 63 PH5570063 DEPTH ADJUST KNOB 63-1 PH5570063-1 SPRING 64 PH5570064 GUIDE PLATE 65 PH5570065 PIN 66 PH5570066 SET SHAFT *67 PH5570067 CARRYING CASE *68 PAW3M ALLEN WRENCH 3MM *69 PAW4M ALLEN WRENCH 4MM * These items are not shown in the illustration.
