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.
Auto(I)/Off(0) Switch: Turn this switch in the "Auto (I)" position 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" pressure.
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 factory set pressure (slightly higher than the pressure switch
"cut-out" setting).
Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pres-
sure in the tank.
Globe Valve/Air Discharge Valve: (sold separately, not shown) Opens and
closes air distribution from compressor. See Air Distribution System paragraph
under Installation.
Regulator (sold separately, not shown): An air pressure regulator or a separate
air transformer which combines the functions of air regulation and/or moisture and
dirt removal is recommended for most applications. See Air Distribution System
paragraph under Installation
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 per-
fectly 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.
Drain Valve: The drain valve is located at the base
of the air tank and is used to drain condensation
at the end of each use.
