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.
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-de-
tergent oil.
OIL FILL PORT/VENT: Pour oil into the Oil Fill Port/Vent when required.
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 always be clean and ven-
tilation opening free from obstructions. Replace lter element when necessary.
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 ex-
haust valves, into the discharge line, through the check valve and/or the pilot valve and into the air tank.
MOTOR/PRESSURE SWITCH: This switch is used to start or stop the air compres-
sor. Moving the switch to the "Auto" (On) position will provide automatic power to
the pressure 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 factory 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.
SAFETY RELIEF VALVE: This valve is designed to prevent system failures by relieving
pressure from the system when the compressed air reaches a predetermined level. The
valve is preset by the manufacturer and must not be modied 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.
AIR TANK PRESSURE GAUGE: The air tank pressure gauge indicates the reserve air pres-
sure in the air tank.
AFTER COOLER: Removes up to 65% of the moisture from discharged compressor air, it
also lowers the gas temperature within 20 degrees of ambient.

EXPLODED VIEW & EXPLANATION OF AIR COMPRESSOR FEATURES
STARTER: the Motor starter provides thermal overload protection. The starter is required
from on motors 5 Hp and above.
LOW OIL SHUT DOWN: the low oil sensor shuts the unit down when the oil levels fall
below an adequate level.
VIBRATION ISOLATOR PADS: Isolators protect the unit from vibration during use. They
also make installation on unlevel surfaces easier.
PNEUMATIC DRAIN: Drains liquid from tank automatically as the water level rises in the
tank.
ELECTRIC DRAIN: Drains liquid form the tank using a timer for frequency and duration
of drain.
