Tank Pressure Gauge: The tank
pressure gauge indicates the reserve
air pressure 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.
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 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).
