1. Check fuse box for blown fuse and replace if
necessary. Re-set circuit breaker. Do not use a
fuse or circuit breaker with higher rating than
that specified for your particular branch circuit.
2. Check for proper fuse; only "Fusetron" Type T
fuses are acceptable.
3. Check for low voltage conditions.
4. Remove check valve and clean or replace if it is
stuck open or closed.
5. Disconnect the other electrical appliances from

switch to the "OFF" position, opening the pressure
release valve. If the valve still doesn't open, it must be
replaced.
Replace with new.
Decrease amount of air usage.
Check the accessory air requirement. If it is higher
than the pressure supplied by your air compressor,
you need a larger compressor.
Replace air intake filter.
