OPERATION CONTROLS
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.
ON/OFF SWITCH (A) FIG.3
Turn this switch ON (press downwards) to provide power to the automatic
pressure switch and OFF to remove power at the end of each use.
PRESSURE SWITCH
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 (B) FIG.3
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 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.
OUTLET PRESSURE GAUGE (C) FIG.3
The outlet pressure gauge indicates the air pressure available at the outlet
side of the regulator. The pressure is controlled by the regulator and is always
less than or equal to the tank pressure.
TWO QUICK CONNECT COUPLERS (E) FIG.3
Connect one or two air hoses at a time to operate air tool or accessory.
TANK PRESSURE GAUGE (D) FIG.3
The tank pressure gauge indicates the reserve air pressure in the tank.
DRAIN VALVE (A) FIG.4
The drain valve is located at the base of the air tank and is used to drain condensation at the end of each use.
SAFETY PRESSURE RELEASE VALVE (F) FIG.3
If the pressure switch does not shut off the air compressor at its cutout pressure setting and the air pressure keeps rising, the safety valve will
protect against high pressure by “popping out” above factory set pressure (slightly higher than the pressure switch cut-out setting).
WARNING!
: If the safety pressure release valve does not work properly, over pressurization may occur, causing air tank rupture or an explosion.
Pull the ring on the safety valve daily to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, it must
be replaced with the same type of valve.
