Portable Electric 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 reset.
MOTOR/PRESSURE SWITCH: This switch is used to start or stop the air compressor.
Moving the switch to the "Auto" (On) position will provide automatic power to the pres-
sure switch which will allow the motor to start when the air tank pressure is below the
factory set "cut-in" pressure. When in the Start/Stop Option, the pressure switch stops
the motor when the air tank pressure reaches the factor set "cut-out" pressure. For
safety purposes, this switch also has a pressure release valve located on the side of the
switch designed to automatically release compressed air from the air compressor pump
head and its discharge line when the air compressor reaches "cut-out" pressure or is
shut off. This allows the motor to restart freely. Moving the switch to the "Off" position
will remove power from the pressure switch and stop the air compressor.
MOTOR THERMAL OVERLOAD: The electric motor has a manual thermal overload
protector. If the motor overheats for any reason, the thermal overload will cut off power,
thus preventing the motor from being damaged. Wait until the motor is cool before
pressing the thermal overload button to reset and begin working again.
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.
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-detergent
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 com-
pressed, 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.
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 (Actual delivered pres-
sure may vary from pump maximum pressure rating).
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.
PILOT VALVE OPTION: When the adjusting knob is turned completely clockwise to
the fully closed position, the air compressor operates in the Start/Stop position. When
the adjusting knob is turned completely counterclockwise to the fully open position, the
air compressor operates in the constant run position.
