OPERATION CONTROLS
IR COMPRESSOR PUMP. To compress air, the piston moves up and down in the cylinder. On
A
the downstroke, air is drawn in through the intake valves. The exhaust valves remain closed. On
he upstroke of the piston, air is compressed. The intake valves close and compressed air is forced
t
out through the exhaust valves.
CHECK VALVE (A) FIG.4. 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 (C) 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.
PRESSURE SWITCH (D) FIG.3. 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 (E) FIG.3. 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.
FIGURE 3
OUTLET PRESSURE GAUGE (F) 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.
TANK PRESSURE GAUGE (G) FIG. 3. The tank pressure gauge indicates the reserve air pressure in the
tank.
FIGURE 4
COOLING SYSTEM. This compressor contains an advanced design cooling system. The cooling
system is working when air is being expelled.
DRAIN VALVE (B) 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.
MOTOR THERMAL OVERLOAD PROTECTOR (RESET (I) FIG. 5). The electric motor has an
automatic thermal overload protector. If the motor overheats for any reason, the thermal overload
protector will shut off the motor. The motor must be allowed to cool before restarting. Press the
eset button.
r
PRESSURE RELEASE VALVE. The pressure release valve located on the side of the pressure
switch, is designed to automatically release compressed air from the compressor head and the
outlet tube when the air compressor reaches “cut-out” pressure or is shut off. The pressure release
valve allows the motor to restart freely. When the motor stops running, air will be heard

running, or continuous leaking after unit reaches “cut-out” pressure.
SAFETY VALVE (H) FIG. 4. If the pressure switch does not shut off the air compressor at its cutout pressure setting, the safety valve will
protect against high pressure by “popping out” at it’s factory set pressure (slightly higher than the pressure switch cut-out setting).

BREAK-IN PROCEDURES & OPERATION
ASSEMBLY AND LOCATION OF THE AIR COMPRESSOR
Your compressor comes almost completely assembled. The muffler part# 27 (refer to parts diagram) must be screwed to the cylinder cover #5.
The oil breather cap #19 must be screwed to the crankcase cover #20. It may be necessary to install the pressure gauges #’s 42 & 43, place teflon
tape around the pressure gauge threaded shaft and fix them in their respective places.
peratre the air compressor in a dry, clean, cool, well ventilated area. The air compressor pump and case are designed to allow for proper
O
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.
*BREAK-IN PROCEDURES*
NOTE: MAKE SURE ALL ASSEMBLY INSTRUCTIONS ABOVE HAVE BEEN FOLLOWED BEFORE DOING THE FOLLOWING
“BREAK-IN PROCEDURES (MUFFLER, OIL BREATHER CAP AND PRESSURE GAUGES). SERIOUS DAMAGE MAY RESULT IF THE
