DESCRIPTION OF OPERATION
Air Compressor Pump:
To compress air
,
the piston moves up and down in the
cylinder. On the down stroke, 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 (B, Fig. 1):
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.
ON/AUTO-OFF Switch (C, Fig.2):
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 (C, Fig. 2):
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” pressure.
Regulator (D, Fig. 4):
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
making a change in pressure setting, always approach the desired pressure
from a lower pressure. When reducing from a higher to a lower setting, fi rst
reduce to pressure less than that desired, and 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 white operating the
accessory.
Outlet Pressure Gauge (E, Fig. 4):
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. See
“Operating Procedures”.
