Know Your Air Compressor
READ THIS INSTRUCTION MANUAL AND SAFETY RULES BEFORE OPERATING
YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with 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/On/Off Switch: Set switch in
AUTO/ON position to provide automatic
power to the pressure switch and OFF
to remove power at the end of each
Pressure Switch (not shown): 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-
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
Regulator: Controls the air pressure shown on the outlet pressure gauge. Turn the
knob clockwise to increase pressure and counterclockwise to decrease pressure.
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.
Check Valve (not shown): When the air compressor is operating, the check valve is
"open", allowing compressed air to enter the air tank. When the air compressor
reaches "cut-out" pressure, the check valve "closes", allowing air pressure to remain
inside the air tank.
Motor Overload Protector (not shown): The motor has an automatic reset thermal
overload protector. If the motor overheats for any reason, the overload protector will
shut off the motor. The motor must be allowed to cool down before restarting. The
compressor will automatically restart after the motor cools.
The motor will automatically restart without warning if plugged
in electrical outlet and "Auto/On/Off" switch is in the
