Troubleshooting Guide for Units in Service for a Period of Time
SYMPTOM
Compressor runs but
builds pressure slowly
Interstage safety valve
pops off when the unit is
running
Oil out breather
Milky oil in crankcase
Compressor will not
shut off

CAUSE
Air leak
Dirty air filter
Valve problem or blown
gasket
Tank cracked
Malfunctioning interstage
safety valve
Low head bolt torque
Defective interstage safety
valve
Worn rings or scored cylinder Replace rings and/or replace cylinder.
Compressor running hot
Low usage of compressor -
water is condesing in the
crankcase
Wrong type of oil
Improper environment
Rotation incorrect
Slight leakage of tank check
valve
Defective control valve
Defective safety valve
SOLUTION
Check the entire system for leaks, including the compressor unit and
any piping attached to the compressor
Air filters need to be changed regularly based on usage and
environment. A dirty filter may appear to be clean. Change filters often.
Check gasket and replace as needed. Other symptoms occur when a
valve is not sealing or a gasket is blown such as higher than normal amp
draw which may trip out the overload or breaker.
Replace the tank. The unit should not be run under any conditions.
Tanks cannot be welded or patched.
Valve problem or blown gasket. High pressure air backflows into the
low pressure side of the pump. This is caused by valve leakage or blown
gasket.
Check and retighten head bolts to specified torque.
Replace interstage safety valve. Under no circumstances plug the safety
valve port
Make sure compressor is running the correct rotation. Compressor
should be clean and in a well ventilated area. Oil should be changed on
regular intervals according to the specifications listed in the manual.
Air filter must be changed as it gets dirty.
Run the compressor continuously for 1 hour. The heat generated during
this running period will evaporate the moisture out of the oil.
Do not use SAE-30 automotive type oil. Using the wrong oil can cause
various problems with the pump and will void the warranty. Only use
the oils that the operating manual recommends.
Unit should not be installed in a poorly vented area or exposed to
extreme cold or hot conditions. Normal operating range should be
between 32°F and 100°F.
Check to make sure the compressor is running the direction of the
flywheel arrow. Air flow should be so that the flywheel directs air across
the head of the pump. Standing in front of the compressor (non-belt
guard side) air should flow back to front.
Air cools and condensates, then leaks back into the pump. Draining
tank of air after use will normally take care of this situation.
Setting too high. If adjusting the setting does not work, replace control
valve.
Make sure tank pressure gauge is reading correctly and if necessary
replace tank safety valve
