eXploded View & eXplanation of air compressor features
safety relief ValVe:
This valve is designed to prevent system failures by re-
lieving 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 compres-
sor 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 continually receives a clean, cool, dry air supply this filter must al-
ways be clean and ventilation opening free from obstructions. Replace filter element
when necessary.
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 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.
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 compressed a second time and forced out the exhaust
valve into the discharge line, through the tank check valve and into the air tank.
OIL FILL PORT
OIL SIGHT GLASS
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 0W non-deter-
gent oil.
