SAFETY RELIEF VALVE: This valve is designed to prevent system failures by reliev-
ing pressure from the system when the compressed air reaches a predetermined
level. The valve is preset by the manufacturer and must not be modified in any
way. To verify the valve is working properly, pull on the ring. Air pressure should
escape. When the ring is released, it will reset.
PILOT VALVE: When the toggle is in the upright position, all air from the air com-
pressor is vented through the discharge muffler. This gives an easy start feature.
TOGGLE
For normal operation, the toggle is in the 90° position.

AIR INTAKE FILTER: This filter is designed to clean air coming into the pump. To
ensure the pump continually receives a clean, cool, dry air supply this filter must
always be clean and ventilation opening free from obstructions. Replace filter
element when necessary.
AIR COMPRESSOR PUMP: To compress air, the piston moves up and down in the
cylinder. On the down stroke, air is drawn in through the air intake valves while
the exhaust valves remain closed. On the up stroke, air is compressed, the intake
valves close and compressed air is forced out through the exhaust valves, into the
discharge line, through the pilot valve and into the air tank.
PUMP OIL DRAIN: To remove oil from pump.
PUMP OIL FILL PORT: To pour oil into the pump.
PRESSURE REGULATOR: The air pressure coming from the air tank is controlled
by the regulator knob. Turn the pressure regulation knob clockwise to increase
discharge pressure, and counterclockwise to decrease discharge pressure.
OUTLET PRESSURE GAUGE: The outlet pressure gauge indicates the air pressure
available at the outlet side of the regulator. This pressure is controlled by the
regulator and is always less or equal to the air tank pressure.
