Troubleshooting Chart
Symptom Possible Cause(s) Corrective Action
Low discharge pressure 1 . Air demand exceeds pump capacity 1 . Reduce air demand or use a compressor with more capacity .
2 . Air leaks 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 . Restricted air intake 3 . Clean the air filter element .
4 . Blown gaskets 4 . Replace any gaskets proven faulty on inspection .
5 . Leaking or damaged valves 5 . Remove head and inspect for valve breakage, misaligned valves,
damaged valve seats, etc . Replace defective parts and reassemble .
Install a new head gasket
each time the head is removed
Pump overheating causes
air filter to melt 1 . Insulating gasket between filter and
head is missing
1 . Install gasket .
2 . Broken valves/blown gasket 2 . Replace valves or install new gasket .
Excessive noise (knocking) 1 . Loose motor or compressor pulley 1 . Loose motor or compressor pulleys are a very common cause of
compressors knocking . Tighten pulley clamp bolts and set-screws .
2 . Lack of oil in crankcase 2 . Check for proper oil level; if low, check for possible damage to
bearings . Dirty oil can cause excessive wear .
3 . Worn connecting rod 3 . Replace connecting rod . Maintain oil level and change oil more
frequently .
4 . Worn piston pin bores 4 . Remove piston assemblies from the compressor and inspect for
excess wear . Replace excessively worn piston pin or pistons, as
required . Maintain oil level and change oil more frequently .
5 . Piston hitting the valve plate 5 . Remove the compressor head and valve plate and inspect for
carbon deposits or other foreign matter on top of piston . Replace
head and valve plate using new gasket . See Lubrication section for
recommended oil .
6 . Noisy check valve in compressor
system
6 . Replace .
