Unloader Blow-Off Pressure: All
models are continuous running units
controlled by tank pressure. When the
maximum tank pressure is obtained,
the unloader valve will blow-off. This
will cause the compressor to exhaust
the air to the atmosphere and not the
tank. This decreases the load on the
engine and allows it to run at a near
no-load condition.
Unloader Reset Pressure: When
the tank pressure drops to a
predetermined point, the unloader
valve closes. The tank pressure will
now increase until it reaches the
unloader blow-off pressure.

INSTALLATION
Location of the Air Compressor
Exhaust from
the gasoline
engine contains deadly carbon
monoxide, which is odorless and
toxic. Operate engine only in well
ventilated areas.
The air compressor must be operated
in a clean, dry, and well-ventilated
area. The air com pres sor's crankcase
and head are de signed with cooling
fi ns to provide proper cooling. The
fan blades of the com pres sor, the
fl ywheel, must be kept clear of obstruc tions that could interfere with the
fl ow of air through the air intake fi lter.
Do not install the air compressor in
a location where heat is excessive.
If the humidity in the operating area
is high, an air fi lter can be installed
on the air outlet adapter to remove
excessive moisture. This type air fi lter
is not provided with this air com pressor and must be purchased sep a rately. Closely follow the instructions
packaged with the fi lter for proper
in stal la tion.
Do not allow the air
compressor to get
wet if it is installed outdoors.
Piping
Plastic or PVC
pipe is not
designed for use with compressed
air. Regardless of its indicated
pressure rating, plastic pipe can
burst from air pressure. use only
metal pipe for air distribution.
If a pipe line is necessary, use pipe
that is the same size as the air tank
outlet. Piping that is too small will
restrict the flow of air. If piping is
over 100 feet long, use the next
larger size. Bury underground lines
below the frost line and avoid pockets
where condensation can gather and
freeze. Apply pressure to lines before
underground lines are buried to make
sure all pipe joints are free of leaks.

OPERATION
Know Your Air Compressor
READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with
the location of various controls and adjustments. Save this manual for future
reference.
Description of Operation
Become familiar with these controls
before operating the unit.
Air Compressor Pump (not shown):
To compress air, the pistons move
up and down in the cylinders. On the
downstroke, air is drawn in through
the air intake fi lter and then through
the air intake valves. The exhaust
valve remains closed. On the upstroke
of the piston, air is compressed. The
intake valves close and compressed
air is forced out through the exhaust
valve, through the outlet tube, through
the check valve and into the air tank.
Working air is not available until
the compressor has raised air tank
pressure above that required at the air
outlet.
Throttle Control (not shown): A
throttle control has been incorporated
as an extra feature. When maximum
tank pressure is reached and the
unloader valve unloads air, it also
activates a throttle control on the
engine. This gas saving feature holds
the engine at a factory-set idling
speed until air pressure in the air
tank drops to reset pressure; it then
reactivates the throttle control and
accelerates the engine to full throttle.
Tank Pressure
Gauge: The
tank pressure
gauge indicates
the reserve air
pressure in the
tank.
Tank
Pressure
Gauge
Unloader Valve: All models are
continuous running outfi ts controlled
by tank pressure. When the maximum
tank pressure is obtained, the
unloader valve will exhaust the
compressed air to the atmosphere
(blow-off). When the pressure
drops to a predetermined point, the
unloader valve closes and causes the
tank pressure to increase.
Unloader Valve
Safety Valve: If the unloader valve
does not shut off the air compressor
at or near 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 blow-off setting).
