DESCRIPTION OF OPERATION
Air Compressor Pump: To compress air, the piston
moves up and down in the cylinder. On the downstroke,
air is drawn in through the intake valves. The exhaust
valves remain closed. On the upstroke of the piston, air
is compressed. The intake valves close and compressed
air is forced out through the exhaust valves, through the
outlet tube, through the check valve and into the air tank.

the tank pressure above that required at the air outlet.
Check Valve: 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.
Pressure Switch: The pressure switch automatically
starts the motor when the 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” pres-
sure.
Regulator: The air pressure coming from the air tank is
controlled by the regulator. Turn the regulator knob
clockwise to increase pressure and counterclockwise to
decrease pressure. To avoid minor readjustment after
makingachangeinpressuresetting,alwaysapproachthe
desired pressure from a lower pressure. When reducing
from a higher to a lower setting, first reduce to pressure
less

Extension Cords

voltage drop and power loss to the motor.
If an extension cord must be used, be sure it is:
• a3-wireextensioncordthathasa3-bladeground-
ing plug, and a 3-slot receptacle that will accept
the plug on the compressor.
• ingood condition.
• no longer than 50 feet.
• 14 gauge (AWG) or larger. (Wire size increases as
gauge number decreases.) 12 AWG, 10 AWG and
8 AWG may also be used. DO NOT USE 16 OR 18
AWG.
Location of the Air Compressor
Your compressor comes to you completely assembled
and ready for use. Operate the air compressor in a dry,
clean, cool and well ventilated area. The air compressor
pump and case are designed to allow for proper cooling.
Clean or blow off dust or dirt that collects on the air
compressor. A clean air compressor runs cooler and
provideslongerservice. Theventilationopeningson your
air compressor are necessary to maintain proper operat-
ingtemperature. Donotplace rags or other containers on
or near these openings.

than that desired, then bring it up to the desired pressure.
Depending on the air requirements of each particular
accessory, the outlet regulated air pressure may have to
be adjusted while operating the accessory.
Outlet Pressure Gauge: The outlet pressure gauge
indicatesthe air pressure available at theoutlet sideofthe
regulator. Thispressure is controlled by the regulatorand
is always less or equal to the tank pressure. See “Oper-
atingProcedures”.
Tank Pressure Gauge: The tank pressure gauge indi-
cates the reserve air pressure in the tank.
CoolingSystem: Thiscompressorcontainsanadvanced
designcooling system. At the heartofthiscoolingsystem
is an engineered fan. It is perfectly normal for this fan to

that the cooling system is working when air is being
expelled.
Air Intake Filter: This unit requires no air filter due to the
unique design of the air intake system.
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.
