TIGHTEN.
Prolonged or excessive
use of air
Decrease amount of air used.
Compressor not large
enough
Check air requirement of accessory.If it is
higher than CFM and pressure supplied by
compressor, you need a larger compressor.
Most accessories are rated at 25% of actual
CFM while running continuously.
Hole in air hose Check and replace if necessary.
Tank leaks WARNING: Immediately replace tank.
DO NOT attempt to repair.

cord size.
Disconnect other applications from circuit.
Operate compressor on a dedicated circuit.
Check valve is stuck open
Wrong wire gauge in cord
or excessive extension
cord length
Check for proper gauge and extension cord
length.
Loose electrical
