IMPORTANT SAFETY INSTRUCTIONS

ISK OF EXPLOSION OR FIRE

WHAT CAN HAPPEN

HOW TO PREVENT IT

It is normal for electrical contacts within the motor and pressure switch to spark.

If electrical sparks from the compressor come in contact with flammable vapors, they may ignite, causing fire or explosion. Restricting any of the compressor ventilation openings will cause serious overheating and could cause fire.

Unattended operation of this compressor could result in personal injury or property damage.

RISK OF BURSTING

WHAT CAN HAPPEN

1. Failure to properly drain condensed water from the tank, causing rust and thinning of the steel tank.

2. Modifications or attempted repairs to the tank.

3. Unauthorized modifications to the unloader valve, safety valve or any other components which control tank pressure.

4. Excessive vibration can weaken the air tank and cause rupture or explosion. Attachments & Accessories; Exceeding the operating pressure of air tools can cause them to explode.

Always operate the compressor in a well ventilated area free of

ombustible materials, gasoline or solvent vapors. If spraying

c flammable materials, locate the compressor at least 20 feet

way from the spray area. An additional length of hose may be

a required. Store flammable materials in a secure location away from the compressor. Never place objects against or on top of the compressor. Operate compressor in an open area at least 12 inches away from any wall or obstruction that would restrict the flow or fresh air to the ventilation openings. Operate compressor in a clean, dry and well ventilated area. Do not operate compressor indoors in a confined area. Always remain in attendance with the compressor when it is operating.

HOW TO PREVENT IT

Drain tank daily or after every use. If the tank developes a leak, replace tank or get a new air compressor. Never drill into, weld or make any modifications to the tank or its attachments.

The tank is designed to withstand specific operating pressures. Never make adjustments or parts substitutions to alter the factory set operating pressures.

For essential control of air pressure, you must install a pressure regulator and pressure gauge to the air outlet.

OPERATION CONTROLS

IR 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

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.

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 escaping fr 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 FOLLOWING BREAK-IN INSTRUCTIONS ARE NOT CLOSELY FOLLOWED.
