CORRECTION
Operate safety valve manually by pulling on ring. If
valve still leaks, it should be replaced.
Remove and clean, or replace.
Decrease amount of air usage.
Check the accessory air requirement. If it is higher than
the SCFM or pressure supplied by your air compres-
sor, you need a larger compressor.
Check and replace if required.
Remove and clean, or replace.
Tighten fittings. (See Air Leaks Section of
Troubleshooting Guide.)
Motor will start automatically when tank pressure
drops below "cut-in" pressure of pressure switch.
Check for proper gauge wire and cord length.
Remove and clean, or replace.
Check wiring connection inside pressure switch and
terminal box area.

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. You should be using a
time delay fuse.
3. Check for low voltage conditions and/or proper
extension cord.
4. Disconnect the other electrical appliances from
circuit or operate the compressor in its own
branch circuit.
Bleed the line by pushing the lever on the pressure
switch to the "off" position; if the valve does not open,
replace it.
Replace regulator.
