It is spring loaded and should not be stuck but
come out about ¼" and then snap back into
position when released.

WARNING: Safety/Relief valve hazards
If the safety/relief valve does not work properly, over-
pressurization may occur causing air tank rupture or
explosion. Occasionally pull the ring on the safety valve
to make sure the safety valve operates freely. If the
valve is stuck or does not operate smoothly, it must be
replaced with a valve having the same pressure rating.
Inspect Air Filter
Inspect the compressor's air filter on a weekly basis. A
dirty air filter will not allow the air compressor to operate
at full capacity.
Clean air filter if dirty and restricted air flow.

Replace the air filter every 12 months or 1000

hours.
Note: Do not operate with the air filter removed.
Keep Compressor Clean
Do not allow air intakes to become blocked. If dust or
debris accumulates in the compressor, clean with a
damp cloth or soft bristle brush.
Note: Do not spray compressor with a garden hose or
pressure washer. Water may enter the compressor
and cause damage to the motor and pump.
