Problem Possible Cause Solutions
Excessive oil
discharge in
air (All
Compressors
have a small
amount of oil
carry over in
compression)
1. Worn piston rings or cylinder.
2. Restricted air intake.
3. Oil level to high.
4. Compressor has exceeded it
duty cycle.
1. Clean or replace air filters.
2. Reduce oil level to
recommended amount.
3. Reduce compressor duty cycle
(repair leaks or add another unit
to handle the excess demand).
Compressor
Overheating
1. Poor ventilation.
2. Dirty cooling surfaces.
3. Compressor is out of its
operating duty cycle.
1. Relocate compressor to any
area with better ventilation (at
least 18 inches from the nearest
wall).
2. Clean all cooling surfaces.
3. Reduce compressor duty cycle
(repair leaks or add another unit
to handle the excess demand).
Excessive belt
wear
1. Pulley out of alignment.
2. Improper belt tension.
3. Pulley damaged of loose.
1. Realign pulley with flywheel.
2. Readjust belt tension.
Compressor
won’t start in
cold
weather
1. Bad check valve.
2. Compressor has wrong grade
oil.
3. Control lines frozen.
1. Use IS 100 (30W) compressor
oil for cold weather conditions.
2. Move compressor to a warmer
location.
3. Put a heat lamp on compressor
to maintain above freezing
temperatures.
Compressor
has excessive
vibration
1. Compressor is not properly
mounted on vibration isolation
pads.
2. Compressor pulley is out of
alignment.
3. Engine is low on fuel of throttle
is out of adjustment.
1. Properly mount compressor on
vibration isolation pads.
2. Re-align pulleys.
3. Check drive engine oil and fuel
level.
4. Re-adjust engine throttle control
(bull whip).
