DO NOT OVERTIGHTEN.

Fittings Leak

Clean or replace air filter element.

Restricted air intake

Decrease amount of air used.Prolonged excessive use of air

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.

Compressor not large enough

Check and replace if necessary.Hole in air hose
