DESCRIPTION OF OPERATION
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
Pressure Switch: The pressure switch automatically starts the motor when the air tank pressure drops below the factory set
the air tank pressure reaches the factory set
Regulator: The air pressure coming from the air tank is controlled by the regulator. Turn the regulator knob clockwise to increase pressure and
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.
