OPERATION CONTROLS
CHECK VALVE
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” pres-
sure, the check valve “closes”, allowing air pressure to remain inside the air tank.
ON/OFF SWITCH (A) FIG.3
Turn this switch ON to provide power to the automatic pressure switch and OFF to
remove power at the end of each use.
RESET (B) FIG.3
This compressor is equipped with a thermal overload. If the motor overheats the rest
will trip and turn the compressor off. Wait 5 minutes to allow for cooling and press the
rest button before attempting to restart the motor.
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 pres-
sure reaches the factory set “Cut-Out” pressure.
REGULATOR (A) 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 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 (B) FIG.4
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.
TANK PRESSURE GAUGE (C) FIG. 4
The tank pressure gauge indicates the reserve air pressure in the tank.
“ONE TOUCH” 1/4” QUICK RELEASE COUPLER (D) FIG. 4
Connect the coil hose with a 1/4” male fitting and connect it this female quick release
coupler.
DRAIN VALVE (A) FIG. 5
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 (A) FIG.6
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.
