MAINTENANCE & REPAIR
(Refer to Exploded View - Page 9)
General Precautions
•
Before performing any service operation, always shut off the air supply and release the system pressure i.e. let the media out so
that the pressure decreases. When storing the pump assembly out of the drum, cover the Filter Tube (60) with Filter Cap (61).
•
Be careful not to damage any parts when dismantling. While removing shafts which do not have key flats, use a Pipe wrench,
Strap wrench or the like. The easiest way to remove such a shaft is to grip it in a vice with aluminium or copper jaws, clamp the
shaft in a hand-drill chuck and then turn the chuck by hand.
•
Be careful when fitting O-rings and seals. Always lubricate them with oil before fitting. They must never be threaded over sharp
edges when being fitted. Lubricate all moving parts with oil.
•
When troubleshooting, be on a lookout for dirt in valves / ball seats, scratches in sealing surfaces & damage in O-rings / seals /
gaskets.
