continuously.

Compressor not large enough

Check and replace if necessary.Hole in air hose

Immediately replace tank. DO NOT attempt to

repair.

than specified for your branch circuit.

Circuit breaker tripped

• Check for low voltage and proper extension cord size.

• Disconnect other applications from circuit. Operate compressor

on a dedicated circuit.

Remove and clean or replace.

Check valve stuck open

Check for proper gauge and extension cord length.

Wrong wire gauge in cord or

excessive extension cord length
