Description of Operation
Become familiar with these controls before operating the unit.
On/Auto/Off Lever: Turn this switch "On/Auto" to provide automatic power to
the pressure switch and "Off" 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 mo-
tor 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 (sold separately): 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 combines 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.
