TROUBLESHOOTING GUIDE
1. Compressor too small for
application
2. Air leaks
3. Restricted intake air
4. Blown gasket(s)
5. Broken or misaligned valves
1. Loose drive pulley or flywheel
2. Low on oil
3. Worn connecting rod or
connecting rod bearing
4. Noisy check valve
1. Worn piston rings
2. Restricted intake air
3. Too much oil in compressor
4. Incorrect oil viscosity
1. Normal. Amount of water will
increase as humidity in the
air increases.
1. Low voltage
2. Malfunctioning pressure switch
3. Malfunctioning check valve
1. Incorrect breaker size
2. Low voltage
3. Malfunctioning motor
4. Loose electrical connections
5. Malfunctioning pressure switch
6. Malfunctioning check valve
1. Malfunctioning check valve
2. Loose fittings or connections
3. Crack or pin hole in tank

1. Reduce air demand or use a compressor
with more air capacity.
2. Listen for air leaks. Apply a soap solution

will form at points of leakage. Tighten
or replace fittings or connections.
3. Clean or replace air filter.
4. Replace necessary gaskets.

legs of incoming power. Check reset button
on motor.
2. Repair or replace pressure switch.
3. Replace check valve or pressure switch.
Do not remove check valve
