SOLUTION
Close petcock
Check fittings with soapy water. Tighten or reseal leaking fittings.
DO NOT OVERTIGHTEN.
Decrease amount of air used.

Most accessories are rated at 25% of actual CFM while running
continuously.
Check and replace if necessary.

circuit breaker with higher rating than specified for your branch
circuit.
• Check for proper fuse; "Fusetron" type T is acceptable.
