Checking Safety valve (Fig. 1)
WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head,
and surrounding parts are very hot, do not touch (see the Hot
Surfaces identified in Fig. 2). Allow compressor to cool prior to
servicing.

properly, over-pressurization may occur, causing air tank rupture or
an explosion.
Before starting compressor, pull the ring on the safety valve to
make sure that the safety valve operates freely. If the valve is stuck
or does not operate smoothly, it must be replaced with the same
type of valve.
