ASSEMBLY OF THE AIR COMPRESSOR
Your compressor comes almost completely assembled.
1) Install the muffler (A) Fig.3 to the cylinder cover (B) by screwing it into place as shown.
2) Remove the plastic cap (A) Fig.4 and replace it with the oil breather cap (B) by screwing it into place as shown.
3) It may be necessary to install the pressure gauges (A and B) Fig.5, place Teflon® tape around the pressure gauge threaded shafts and and
screw the pressure gauges in their respective places.
4) Install the female quick connect (C) Fig.5 to the pressure regulator housing, place Teflon® tape around the female quick connect threaded
shaft and screw it into place. Tighten using wrench.
LOCATION TO USE THE AIR COMPRESSOR
Operatre the air compressor in a dry, clean, cool, 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 provides longer service. The ventilation
openings on your air compressor are necessary to maintain proper operating temperature. Do not
place rags or other containers on or near these openings.
ADDITIONAL REGULATORS AND CONTROLS
Since the air tank pressure is usually greater than that which is needed, a regulator is employed to
control the air pressure ahead of any individual driven device. Separate air transformers which
combine the function of air regulation, moisture and dirt removal should be used where applicable.
OPERATION CONTROLS
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.
CHECK VALVE (A) FIG.7.
When the air compressor is operating, the check valve is “open”,
allowing compressed air to enter the air tanks. When the air compressor reaches “Cut-Out”
pressure, the check valve “closes”, allowing air pressure to remain inside the air tanks.
ON/AUTO-OFF SWITCH (B) FIG.6.
Turn this switch ON to provide power to the automatic pressure
switch and OFF to remove power at the end of each use.
PRESSURE SWITCH (A) FIG.6.
The pressure switch automatically starts the motor when the tank
pressure drops below the factory set “Cut-In” pressure. It also stops the motor when the air tank
pressure reaches the factory set “Cut-Out” pressure.
REGULATOR (D) FIG.6.
The air pressure coming from the air tanks is controlled by the regulator. Turn the regulator knob clockwise to increase
pressure and counterclockwise to decrease pressure. To avoid minor readjustment after making a change in the pressure setting, always
approach the desired pressure from a lower pressure. When reducing from a higher to a lower setting, first reduce the pressure less 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.
