D. DIAPHRAGM INSPECTION & REPLACEMENT Diaphragm replacement should rarely be necessary if the air supply is regulated and free of contamination and if the gap between the friction and drive disc is properly set. Separate the air cylinder and piston by pulling apart taking care not to bend pins. Pinch the diaphragm and pull from the grooves which retain it. Make sure that the retaining grooves and surface underneath the diaphragm are clean & free from debris.
