Gasoline Air Compressor Manual
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 reseat.
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.
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 en-
sure 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.
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 non-deter-
gent oil.
aIR coMPRessoR PuMP:
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
exhaust 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 com-
pressed 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 re-
serve air pressure in the air tank (s).
PRessuRe ReGulatoR:
The air pressure coming from the air tank is con-
trolled by the regulator knob. Turn the pressure regulation knob clockwise to
increase discharge pressure, and counterclockwise to decrease discharge pres-
sure.
outlet PRessuRe GauGe:
The outlet pressure gauge indicates the air pres-
sure 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 compressor 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 counterclockwise.
