CORRECTION
Excessive tank pressure - safety
valve pops off.

tor when compressor reaches “cut-out”
pressure.
Move the pressure switch lever to the “OFF” position.
If the outfit doesn’t shut off, unplug. If the electrical
contacts are welded together, replace the pressure
switch.
Pressure '"cut-out" too high.
Return the outfit to an authorized dealer to check and
adjust, or replace switch.
