Air Compressor Pump (Included in compressor as-

sembly): To compress air, the piston moves up and down

in the cylinder. On the downstroke, air is drawn in through

the air 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 tubes,

through the check valve and 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.

Cooling System (Included in compressor assembly):

This compressor contains an advanced design cooling

system. At the heart of this cooling system is an engi-

neered 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 Intake Filter (Included in compressor assembly):

The unit requires no air filter due to the unique design of the

air intake system.

Check Valve (Not Shown): When the air compressor is

operating, the check valve is “open”, allowing com-

pressed 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 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.

Regulator: The air pressure coming from the air tank is

controlled by the regulator. Turn the regulator knob

clockwise to increase pressure and counter-clockwise to

decrease pressure. To avoid minor readjustment after

making a change in pressure setting, always approach the

desired pressure from a lower pressure. When reducing

from a higher to a lower setting, first reduce to some

pressure less than that desired, then bring up to the

desiredpressure. Depending on the air requirements of

each particular accessory, the outlet regulated air pres-

sure may have to be adjusted while operating the acces-

sory.

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 or equal to the tank pressure. See

“Operating Procedures”.

Tank Pressure Gauge: The tank pressure gauge indi-

cates the reserve air pressure in the tank.

Drain Valve (Not Shown): The drain valve is located at the

base of the air tank and is used to drain condensation at

the end of each use.

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.
