Air compressor not large enough
Check air requirement of accessory used. If it is
higher than CFM and pressure supplied by
compressor, a larger compressor is needed. Most
accessories are rated at 25% of actual CFM while
running continuously.
Low voltage
Check power source (outlet or generator) with
volt-meter.
Clogged Air Filter Clean or replace air filter.
Lack of proper ventilation/room
temperature too high.
Relocate compressor to an area with cool, dry and
well-circulated air.
