E
Move the pressure switch to the OFF position. If the motor does
not shut off, unplug the air compressor. If the electrical contacts
are welded together, replace the pressure switch.
Check accessory air requirement. If higher than the CFM or
pressure supply of the air compressor, then larger air compressor
is required.
Replace the pressure switch.
Operate safety relief valve manually by pulling on test ring. If it
still leaks, replace the safety relief valve.
Defective pressure switch. Replace the pressure switch.
WARNING: Drain air before tightening.
Tighten fittings so air cannot be heard escaping. Check joint with
soap solution. Do not overtighten.
Air tank must be replaced. Do not attempt to repair air tank.
Adjust pressure regulator knob to proper setting or replace.
Replace with larger hose or connectors.
Remove pump head and inspect valve plate and reed valve.
Clear or replace valves as required.
Drain air tank after every use. Drain air tank more often in humid
weather and use an air line filter.
Relocate the compressor.
Check for leaks. Replace if necessary.
