Troubleshooting
Problem Possible Causes Likely Solutions
Compressor does
not start or restart
Incorrect power supply.1.
No power at outlet. 2.
Power cord not plugged in 3.
properly.
Thermal overload switch 4.
tripped.
Building power supply circuit 5.
tripped or blown fuse.
Tank(s) already pressurized.6.
Cord wire size is too small or 7.
cord is too long to properly
power compressor.
Compressor needs service.8.
Check that circuit matches compressor requirements.1.
Reset circuit breaker, or have outlet serviced by a qualied 2.
technician.
Check that cord is plugged in securely. 3.
Turn off Tool. Turn off Compressor and wait for it to cool down. 4.
Press reset button. Resume operation.
Reset circuit or replace fuse. Check for low voltage conditions. 5.
It may be necessary to disconnect other electrical appliances
from the circuit or move the compressor to its own circuit.
No problem. Compressor will start when needed.6.
Use larger diameter or shorter extension cord or eliminate 7.
extension cord. See Recommended Wire Gauge for Extension
Cords in Safety section.
Have unit inspected by a qualied technician.8.
Compressor builds
pressure too slowly
Incorrect power supply.1.
Crankcase overlled with oil or 2.
oil too thick.
Working environment too cold. 3.
Safety valve needs service. 4.
Loose ttings.5.
Check that circuit matches compressor requirements.1.
Drain oil and rell to proper level with recommended oil. 2.
Move unit to a warmer location. Check that recommended oil 3.
is in crankcase.
Listen for air leaking from valve. If leaking replace with 4.
identical valve with same rating.
Reduce air pressure, then check all ttings with a soap solution 5.
for air leaks and tighten as needed. Do not overtighten.
Compressor not
building enough air
pressure
Filters need cleaning/replacing.1.
Crankcase oil too thick. 2.
Check Valve needs service.3.
Compressor not large enough 4.
for job.
Loose ttings. 5.
Hose or hose connections not 6.
adequate.
High altitude reducing air 7.
output.
Check inlet and outlet lters. Clean and/or replace as needed.1.
Drain oil and rell to proper level with recommended oil.2.
Have technician clean or replace, as needed.3.
Check if accessory SCFM is met by Compressor. If 4.
Compressor cannot supply enough air ow (SCFM), you need
a larger Compressor.
Reduce air pressure, then check all ttings with a soap solution 5.
for air leaks and tighten as needed. Do not overtighten.
Replace with larger hose and/or hose connections. 6.
You may need a larger compressor if you are situated in a high 7.
altitude location.
High Oil
Consumption
Crankcase oil too thin.1.
Unit not on level surface.2.
Crankcase vent clogged.3.
Drain oil and rell to proper level with recommended oil.1.
Reposition unit on a level surface.2.
Clean Crankcase vent.3.
Follow all safety precautions whenever diagnosing or servicing the
compressor. Disconnect power supply before service.
