Component Identification
SAFETY RELIEF VALVE: This valve is designed to pre- vent system failures by relieving pressure from the sys- tem 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 posi- tion, all air from the air compressor is vented through the discharge muffler. This gives an easy start feature. 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 continu- ally receives a clean, cool, dry air supply this filter must always be clean and ventilation opening free from ob- structions. Replace filter element when necessary.
OIL FILL PORT/VENT: Pour oil into the Oil Fill Port/Vent when required.
OIL SIGHT GLASS: The Oil Sight Glass displays the oil level in the pump. The oil level should be at the center of the Oil Sight Glass. If low, add SAE 30W

AIR COMPRESSOR PUMP (Single Stage): To compress air, the pistons move up and down in the cylinders. On the downstroke, air is drawn in through the air intake valves while the exhaust valves remain closed. On the upstroke, 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.
AIR COMPRESSOR PUMP (Two Stage): A two stage compressor pump uses two different size cylinders with the intake valve of the second smaller cylinder linked to the exhaust valve of the first larger cylinder. On the down stroke of the large cylinder, air is drawn through the intake valve while the exhaust valve remains closed. On the upstroke, air is compressed, the intake valve closes and compressed air is forced out through the ex- haust valve, into the inter cooler and through the intake valve of the second smaller cylinder on its down stroke. On the upstroke of the smaller cylinder, the intake valve closes and the compressed air is compressed a second time and forced out the exhaust valve into the discharge line, through the tank check valve and into the air tank.
AIR TANK PRESSURE GAUGE: The air tank pressure gauge indicates the reserve air pressure in the air tank (s).
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.
AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the air tank(s) after the air com- pressor is shut off. NEVER attempt to open the drain valve when more than 10 PSI of air pressure is in the air tank! To open the drain valve, turn the knob coun- terclockwise.
