Safety Valve - Inspection and
Replacement
IF THE SAFETY 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 THAT THE SAFETY VALVE OPER-
ATES FREELY. IF THE VALVE IS STUCK OR
DOES NOT OPERATE SMOOTHLY, IT MUST
BE REPLACED WITH A VALVE HAVING THE
SAME PRESSURE RATING.
The safety valve is set at the factory to a pressure
approximately 15 pounds higher than the rated pressure
of the outfit. If the pressure switch malfunctions and does
not shut off the motor automatically at maximum tank
pressure, the safety valve will protect the air tank against
excessive air pressure by popping off at its preset
pressure.
SERIOUS INJURY OR DAMAGE MAY OCCUR
IF PARTS OF THE BODY OR LOOSE ITEMS
GET CAUGHT IN MOVING PARTS. NEVER
OPERATE THE OUTFIT WITH THE BELT
GUARD REMOVED. THE BELT GUARD
SHOULD BE REMOVED ONLY WHEN THE
COMPRESSOR POWER IS DISCONNECTED.
