TROUBLESHOOTING
POSSIBLE CAUSE
1. Lubricant viscosity too low.
2. Lubricant level too low.
3. Detergent type lubricant being used.
4. Cylinder(s) or piston(s) scratched, worn or scored.
5. Extremely dusty atmosphere.
6. Worn cylinder finish.
1. Clogged or dirty inlet and/or discharge line filter.
2. Air leaks in air discharge piping.
3. Lubricant viscosity too high.
4. Compressor valves leaky, broken, carbonized or loose.
5. Piston rings damaged or worn (broken, rough or scratched).
Excessive end gap or side clearance.
6. Piston rings not seated, are stuck in grooves or end gaps not
staggered.
7. Cylinder(s) or piston(s) scratched, worn or scored.
8. Defective safety/relief valve.
1. Loose beltwheel or motor pulley, excessive end play in motor
shaft or loose drive belts.

3. Improper line voltage.
4. Compressor valves leaky, broken, carbonized or loose.
5. Defective ball bearings on crankshaft or motor shaft.
1. Lubricant viscosity too high.
2. Leaking check valve or check valve seat blown out.
3. Ambient temperature too low.
4. Bad motor.
1. Inadequate ventilation around beltwheel.
2. Drive belts too tight or misaligned.
3. Compressor valves leaky, broken, carbonized or loose.
4. Wrong beltwheel direction of rotation.
1. Loose beltwheel or motor pulley, excessive end play in motor
shaft or loose drive belts.
2. Lubricant viscosity too high.
3. Lubricant level too low.
4. Compressor valves leaky, broken, carbonized or loose.
5. Carbon build-up on top of piston(s).
6. Defective ball bearings on crankshaft or motor shaft.
7. Leaking check valve or check valve seat blown out.
1. Air leaks in air discharge piping.
2. Pressure switch differential too narrow.
3. Leaking check valve or check valve seat blown out.
4. Excessive condensate in receiver tank.
