Portable Gasoline Air Compressor Manual 9
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 modied 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 horizontal position, all air from the air com-
pressor is vented through the discharge mufer. This gives an easy start feature. For
normal operation, the toggle is in the vertical position.
AIR INTAKE FILTER: This lter is designed to clean air coming into the pump. To
ensure the pump continually receives a clean, cool, dry air supply this lter must al-
ways be clean and ventilation opening free from obstructions. Replace lter 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: 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 TANK PRESSURE GAUGE: The air tank pressure gauge indicates the reserve
air pressure in the air tank (s).
OPTIONAL PRESSURE REGULATOR: The air pressure coming from the air tank is
controlled by the regulator knob. Turn the pressure regulation knob clockwise to in-
crease discharge pressure, and counterclockwise to decrease discharge pressure.
OPTIONAL 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.
