Safety Valve-Replacement

does not work
properly, over-pressurization can
occur and cause air tank rupture
or explosion. Daily pull the ring on
the safety valve and make sure it
operates freely. If the valve is stuck
or does not operate smoothly, it
must be replaced with the same
type of valve having an identical
pressure rating.
To Remove Safety Valve:
1. Make sure the air compressor unit
is off and disconnect the spark
plug wire.
2. Open the shut-off valve and allow
all air to bleed from the tank.
Monitor tank pressure gauge as
tank is emptied.
