You have purchased a complete compressor outfit con-
sisting of an air compressor, ASME approved air tank,
gasoline engine, and associated controls and instru-
ments. The compressor outfit you have selected is a
two stage stationary outfit.
Your new compressor can be used for operating paint
sprayers, air tools, grease guns, air brushes, caulking
guns, and sand blasters, inflating tires and plastic toys,
The pistons move up and down in the cylinder to com-
press air. On the downstroke, air is drawn in 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 pressure becomes available when the compressor
has raised the tank pressure above that required at the
air discharge valve. The air intake must be kept clear
of all obstructions which could interfere with air delivery
to the compressor.
All gasoline compressor outfits are continuously run-
ning outfits controlled by tank pressure. At maximum
tank pressure the unloader valve exhausts air to atmo-
sphere (blowoff); tank pressure closes the check valve
retaining air pressure inside the tank. When tank pres-
sure drops to a pre-determined pressure, the unloader
Each air compressor outfit is carefully checked before
shipment. With improper handling, damage may
result in transit and cause problems in compressor
operation.
Immediately upon arrival, check equipment for both con-
cealed and visible damages to avoid expenses being
incurred to correct such problems. This should be done

spraying weed killer and insecticides, etc. An air pres-
sure regulator may be necessary for some of these
applications.
A regularly scheduled program of preventive mainte-
nance is necessary to insure the long life that has been
designed into your compressor outfit. This instruction
manual, along with maintenance, will keep your com-
pressor outfit in good working order. Before operating
or performing any maintenance on your outfit, refer to
these publications.
valve closes, and air pressure opens the check valve
allowing compressed air into the tank. As maximum
tank pressure is reached, if the unloader valve mal-
functions and compressed air is not exhausted at or
near its blowoff setting, the air tank safety valve will
protect the air tank against high pressure by popping
at its factory set pressure. The safety valve popping
pressure is slightly higher than the unloader valve blowoff
pressure.
Your compressor outfit is equipped with a gas saving
throttle control device. When maximum tank pressure
is reached and the unloader valve opens, the throttle
control is also activated. The throttle control holds the
engine at a factory set idling speed until air pressure in
the tank drops to reset or minimum tank pressure. At
reset pressure when the unloader valve closes, the
throttle control is reactivated and the engine acceler-
ates to full throttle.
