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
Remove and clean or replace. Restricted check valve
Check and replace if necessary. Hole in air hose
Immediately replace tank. DO NOT attempt to

stop
Excessive starting and
stopping, while not in
use
Air leaks from regulator,
or regulator does not
regulate pressure
Regulated pressure

when air accessory is
being used
Circuit breaker trips
(fuse blows) too often
Relocate compressor to an area with cool, dry and well-circulated
air.
Poor ventilation
Clean all cooling surfaces of pump and motor thoroughly. Dirty cooling surfaces
Replace worn parts and reassemble with new seals. Leaking valve
Overheating
Furnish adequate power. Low voltage
