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 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 exhaust
valves, into the discharge line,
through the pilot valve and into
the air tank.
PILOT VALVE: When the toggle
is in the upright position, all air
from the air compressor is vented
through the discharge muffler.
This gives an easy start feature.
For normal operation, the toggle
is in the 90° position.
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 modified in any way.
To verify the valve is working
properly, pull on the ring. Air pres-
sure should escape. When the
ring is released, it will reseat.

AIR TANK DRAIN VALVE:
The drain valve is used to
remove moisture from the
air tank(s) after the air com-
pressor 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 counter-
clockwise.

GAUGE:
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 pres-
sure regulation knob clockwise
to increase discharge pres-
sure, and counterclockwise
to decrease discharge pres-
sure.

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.
OIL SIGHT GLASS: The oil sight
glass will register the amount of
oil in the pump. Ensure the oil
level in the air compressor pump
is adequate. If low, add SAE-30W
non-detergent oil.
