when in the
Auto mode.
Air compressor is not large enough.
Check air requirement of accessory used. If it is
higher than SCFM and pressure supplied by
compressor, a larger compressor is needed.
Most accessories are rated at 25% of actual
SCFM 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 air compressor to an area with cool,
