DESCRIPTION OF
OPERATION (con't)
AIR INTAKE FILTER: This filter is designed to
clean air coming into the compressor pump.
This filter must always be clean and free
from obstructions. See "Maintenance".
AIR COMPRESSOR PUMP: To compress air,
the pistons move up and down in the
cylinder. On the down stroke, air is drawn in
through the air intake valve. The exhaust
valve remains closed. On the upstroke of
the piston, air is compressed. The intake
valve closes and compressed air is forced
out through the exhaust valve, through the
outlet tube, through the check valve and
into the air tank. Useable air is not
available until the compressor has raised
the air tank pressure above that required at
the air outlet.
UNLOADER VALVE: When the compressor
pumps the factory set amount of air into
the tank, the unloader will blow off. This
puts the engine in idle mode and the
unloader will open, allowing the unused
air to escape preventing over pressuring
of the tank.
SAFETY VALVE: If the engine does not
idle down at its "cut-out" pressure
setting, the safety valve will protect
against high pressure by "popping out" at
its factory set pressure (slightly higher than
the unloader valve "cut-out" setting). Do not
tamper with or attempt to eliminate the
safety relief valve.
TANK PRESSURE GAUGE: The tank pressure
gauge indicates the air pressure in the tank.

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
tank pressure. See "Operating Procedures".
REGULATOR: The air pressure coming from
the air tank is controlled by the regulator
knob. Turn the knob clockwise to increase
pressure and counter-clockwise to decrease
pressure. To avoid minor re-adjustment
after making a change in pressure setting,
always approach the desired pressure from
a lower pressure. When reducing from a
higher to a lower setting, first reduce to
some pressure less than desired pressure.
Depending on the air requirements of each
particular accessory, the outlet regulated
air pressure may have to be adjusted while
you are operating the accessory.
INSTALLATION AND
BREAK-IN PROCEDURES
LOCATION OF THE AIR COMPRESSOR
Locate the air compressor in a clean, dry,
and well-ventilated area. The air filter must
be kept clear of obstructions, which could
reduce air delivery of the air compressor.
The air compressor should be located at
least 12 inches away from the wall or other
obstructions that will interfere with the
flow of air. The air compressor head and
shroud are designed to allow for proper
cooling. If humidity is high, an air filter can
be installed on the air outlet adapter to
remove excessive moisture. Follow the
instructions packaged with the air filter for
proper installation.
