Question about Tools & Hardware - Others
Many causes for this problem. Some things to check. Push the driver up by hand to see if it moves easily /hard. If hard, check for bent driver or dry cylinder. If it moves easily, check piston oring too worn and /or air could be leaking down past the bumper area. Most guns have very close fitting bumper or a seal below bumper. If too much air leaks down past bumper driver will not return fully. Check seal could be loose or broken. Remove cylinder and look for check seal covering a row of holes on outer/mid to lower part of cylinder. could be a band or oring and should fit rather tight. If ok only other parts to check are the headvalve and piston stop. Piston stop should not have cracks or missing pieces (piston stop slows/stops piston when it returns to top). Head valve should be well lubed. Good luck
