1. Check fuse box for blown fuse
and replace if necessary. Reset
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 dual
element time delay fuses are
acceptable. Use a time delay
fuse.
3. Check for low voltage conditions
and/or proper extension cord.
4. Remove check valve and clean
or replace if it is stuck open or
closed.
5. Disconnect the other electrical
appliances from circuit or
operate the air compressor on
its own branch circuit.
On an ON/AUTO pressure switch
equipped with a pressure relief
valve, bleed the line by pushing the
pressure switch to the OFF position.
If valve does not open, bend the
lever until it does. If valve still fails
to bleed, replace the valve
assembly.
