Troubleshooting Chart
Low discharge pressure 1 Air demand exceeds
pump capacity
2 Air leaks
3 Restricted air intake
4. Blown gaskets
5 Leaking or damaged
valves

1 Reduce air demand or use a compressor with more capacity
2 Listen for escaping air Apply soap solution to all fittings
and connections. Bubbles will appear at points of leakage
Tighten or replace leaking fittings or connections
3 Clean the air filter element.
4. Replace any gaskets proven faulty on inspection
5 Remove head and inspect for valve breakage, misaligned
valves, damaged valve seats, etc Replace defective parts and
reassemble
I_CAUTIONI headlnStall a r_w head gasket each time theis removed

2 Lack of oil in clankcase
3 Worn connectingrod
4 Worn piston pin bores
5 Piston hitting the valve
plate
1 Install gasket
2 Replace valves or install new gasket
1 Loose motol ol compressor pulleys are a very common cause
of compressors knocking. Tighten pulley clamp bolts and set-
SCl e ws.
2 Check for proper oil level; if low, check for possible damage
to bealings. Dilty oil can cause excessive wear.
3 Replace connecting rod Maintain oil level and change oil
more frequently.
4 Remove piston assemblies horn the compressol and inspect
for excess weal Re e place excessively worn p iston pin or
pistons, as required. Maintain oil level andchange oil more
frequently.
5 Remove the compressol head and valve plate and inspect for
carbon deposits ol othel foleign mattel on top of piston
