GENERAL
You have purchased an air compressor unit consisting of
a 2 cylinder, single stage air compressor pump, an air
tank, air hose, wheels, handte, air chuck and associated
controls.
Your air compressor can be used for operating paint
spray guns, air tools, caulking guns, grease guns, air
brushes, sandblasters, power washers, inflating tires
and plastic toys, spraying weed killers, insecticides, etc.
An air line filter is usually required for removal of mois-
ture and oil vapor in compressed air when a paint spray
gun is used.
iNFORMATiON
An in-line lubricator is usually required for air tools to
prolong toot life.
Separate air transformers which combine the functions
of air regulation and/or moisture and dirt removal should
be used where applicable.
These accessories can be purchased from most Sears
stores or through the Sears General catatog or Power
Toot catalog.

VALVE
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 filter 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 vatve 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.
Check Vatve: When the air compressor is operating, the
check valve is "open", allowing compressed air to enter
the air tank. When the air compressor reaches "cut-out"
pressure, the check vaIve "closes", aJlowing air pressure
to remain inside the air tank.
Pressure Remeaee Valve:The pressure release valve
located on the side of the pressure switch, is designed to
automatically release compressed air from the com-
pressor head and the outlet tube when the air compres-
sor reaches "cut-out" pressure or is shut off. If the air is
not release& the motor wilt try to start, but will be unable
to. The pressure release vatve allows the motor to re-
start freely. When the motor stops running, air wilt be
heard escaping from the valve for a few seconds. No air
should be heard leaking from the valve when the motor is
running.
Safety Valve:tfthe pressure switch does not shut off the
air compressor at or near its cut-out pressure setting, the
safety valve will protect against high pressure by "pop-
ping out" at its factory-.set pressure (slightJy higher than
the pressure switch cut-out setting).
