SAFETYOPERATIONMAINTENANCE SETUP
Problem Possible Causes Likely Solutions
Overheating 1� Air filters need cleaning/replacing�
2� Unusually dusty environment�
3� Extension cord used�
4� Unit not on level surface�
1� Check inlet and outlet filters�
Clean and/or replace as needed�
2� Clean and/or replace filters more often or
move unit to cleaner environment�
3� Eliminate extension cord�
4� Reposition unit on a level surface�
Thermal overload
protector cuts
out repeatedly
1� Low voltage�
2� Lack of proper ventilation/
room temperature too high�
3� Wrong gauge wire or length
of extension cord�
1� Check with voltmeter�
2� Move compressor to well-ventilated area�
3� Check for proper gauge wire and cord length�
Compressor
starts and stops
excessively
1� Loose fittings�
2� Compressor not large enough for job�
1� Reduce air pressure, then check all fittings with a soap
solution for air leaks and tighten as needed�
Do not overtighten�
2� Check if accessory CFM is met by Compressor�
If Compressor doesn’t reach accessory CFM,
you need a larger Compressor�
Excessive noise,
vibration
1� Loose fittings�
2� Unit not on level surface�
1� Reduce air pressure, then check all fittings with a soap
solution for air leaks and tighten as needed�
Do not overtighten�
2� Reposition unit on a level surface�
Moisture in
discharge air
1� Too much moisture in air�
2� Excessive water in air
tank High humidity�
1� Install inline air filter/dryer, and/or relocate
to less humid environment�
2� Drain tank Move to area of less
humidity; use air line filter�
Safety Valve “pops” Safety valve needs service� Pull on test ring of safety valve� If it still pops, replace�
Compressor runs
continuously
1� Defective pressure switch�
2� Excessive air usage�
1� Take compressor to qualified technician�
2� Decrease air usage; compressor not large
enough for tool’s requirement�
Air leaks from
pump or fittings
Loose fittings� Reduce air pressure, then check all fittings with a soap
solution for air leaks and tighten as needed�
Do not overtighten�
Air leaks from tank Defective or rusted tank� Have tank replaced by a qualified technician�
Drain moisture from tank daily to prevent future corrosion�
Follow all safety precautions whenever diagnosing or servicing the compressor.
Disconnect power supply before service.
