Description of Operation
Become familiar with these controls before operating the unit.
On/Auto/Off Switch: Turn this
switch ON 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 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).
Outlet Pressure Gauge: The outlet pressure gauge indicates the air pressure
available at the outlet side of the regulator. This pressure is controlled by the
regulator and is always less than or equal to the tank pressure.
Tank Pressure Gauge: The tank pressure gauge indicates the reserve air
pressure in the tank.
Regulator: Controls the air pressure shown on the outlet pressure gauge. Pull
the knob out and turn clockwise to increase pressure and counterclockwise to
decrease pressure. When the desired pressure is reached push knob in to lock
in place.
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.
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.
