PROBLEM
CAUSE
CORRECTION
Excessive tank pressure -
safety valve pops off.
Pressure switch does not shut off
motor when compressor reaches
"cut-out" pressure.
Move the pressure switch lever to the "OFF"
position. If the outfit doesn't shut off, and the
electrical contacts are welded together, replace
the pressure switch.
If the contacts are good, check to see if the pin
in the bottom of the pressure release valve is
stuck. If it does not move freely, replace the
valve.
Return the outfit to a Service Center to check and
adjust, or replace switch.
Pressure switch "cut-out" too high.
Air leaks at fittings.
Tube fittings are not tight enough.
Tighten fittings where air can be heard escaping.
Check fittings with soapy water solution. DO
NOT OVER-TIGHTEN.
Air leaks at check valve.
Defective or dirty check valve.
A defective check valve results in a constant air
leak at the pressure release valve when there is
pressure in the tank and the compressor is shut
off. Remove and clean or replace check valve.
DO NOT OVER-TIGHTEN.
Air leaks at pressure switch
release valve.
Defective pressure switch release

parts.
Pressure reading on the
regulated pressure gauge
drops when an accessory
is used.
It is normal for "some" pressure
drop to occur.
If there is an excessive amount of pressure drop
when the accessory is used, adjust the regulator
following the instructions in "Description of Op-

conditions (while accessory is being
used).
