conditions. It may be necessary to disconnect other
electrical appliances from the circuit or move the
compressor to its own circuit.

Use larger diameter or shorter extension cord or 7.
eliminate 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 2.
oil.
Move unit to a warmer location. Check that 3.
recommended oil 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 5.
solution for air leaks and tighten as needed. Do not
overtighten.

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 5.
solution 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 7.
in a high altitude location.
