DESCRIPTION OF OPERATION
Become familiar with these controls
before operating the unit.
On/Auto(I)/Off(O) Switch: Turn this
switch "On/Auto(I)" to provide auto-
matic power to the pressure switch and
"Off(O)" to remove power at the end of
each use.
Pressure Switch: The pressure switch
automatically starts the motor when
the air tank pressure drops below the
factory set "cut-in" pressure. It stops
the motor when the air tank pressure
reaches the factory set "cut-out" pres-
sure.
Safety Valve: If the pressure switch
does not shut off the air compressor
at its "cut-out" pressure setting, the
safety valve will protect against high
pressure by "popping out" at its fac-
tory set pressure (slightly higher than
the pressure switch "cut-out" setting).
Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure in the tank.

OPERATION

On/Auto(I)/Off(O) Switch
Pressure Switch
Globe Valve
Globe Valve: Opens and closes air
discharge valve. Turn knob counter-
clockwise to open and clockwise to
close.
Regulator (sold separately, not
shown): An air pressure regulator or a
separate air transformer which com-
bines the functions of air regulation
and/or moisture and dirt removal is
recommended for most applications.
Cooling System (not shown): This
compressor contains an advanced
design cooling system. At the heart of
this cooling system is an engineered
fan. It is perfectly normal for this fan to
blow air through the vent holes in large
amounts. You know that the cooling
system is working when air is being
expelled.
Air Compressor Pump (not shown):
Compresses air into the air tank.
Working air is not available until the
compressor has raised the air tank
pressure above that required at the air
outlet.
