WARNING
ALL ELECTRICAL CONNECTIONS MUST BE DONE BY A QUALIFIED ELECTRICIAN. FAILURE TO COMPLY MAY RESULT IN SERIOUS INJURY! ALL ADJUSTMENTS OR REPAIRS MUST BE DONE WITH THE COMPRESSOR DISCONNECTED FROM THE POWER SOURCE. FAILURE TO COMPLY MAY RESULT IN SERIOUS INJURY!
POWER SUPPLY
WARNING: YOUR COMPRESSOR MUST BE CONNECTED TO A 110V, WITH A MINIMUM 15-AMP. BRANCH CIRCUIT AND USE A 15-AMP TIME DELAY FUSE OR CIRCUIT BREAKER. FAILURE TO CONNECT IN THIS WAY CAN RESULT IN INJURY FROM SHOCK OR FIRE.
GROUNDING
Your Compressor must be properly grounded. Not all outlets are properly grounded. If you are not sure if your outlet is properly grounded, have it checked by a qualified electrician.
WARNING: IF NOT PROPERLY GROUNDED, THIS COMPRESSOR CAN CAUSE ELECTRICAL SHOCK, PARTICULARLY WHEN USED IN DAMP LOCATIONS. TO AVOID SHOCK OR FIRE, IF THE POWER CORD IS WORN OR DAMAGED IN ANY WAY, HAVE IT REPLACED IMMEDIATELY.
If this Compressor should malfunction or breakdown, grounding provides a path of least resistance for electric current, to reduce the risk of electric shock. This cut-off is equipped with a cord having an equipmentgrounding conductor and grounding plug. The plug must be plugged into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.
WARNING: TO MAINTAIN PROPER GROUNDING, DO NOT REMOVE OR ALTER THE GROUNDING PRONG IN ANY MANNER.
110V OPERATION
As received from the factory, your Compressor is ready to run for 110V operation. This machine is intended for use on a circuit that has an outlet and a plug which looks like the one illustrated in Fig.1.
WARNING: DO NOT USE A TWO-PRONG ADAPTOR FOR THEY ARE NOT IN ACCORDANCE WITH LOCAL CODES AND ORDINANCES. NEVER USE IN CANADA.
EXTENSION CORDS
The use of any extension cord will cause some loss of power. Use the table below to determine the minimum wire size (A.W.GAmerican Wire Gauge) extension cord. Use only 3-wire extension cords which have 3-prong grounding type plugs and 3-hole receptacles which accept the tool’s plug.
For circuits that are further away from the electrical circuit box, the wire size must be increased proportionately in order to deliver ample voltage to the cut-off motor. Refer to Fig.2 for wire length and size.
OPERATION CONTROLS
- AIR 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 the upstroke of the piston, air is compressed. The intake valves close and compressed air is forced 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.
- 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.
- 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 reset 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 from this valve for a few seconds. No air should be heard leaking when the motor is 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).
WARNING!: If the safety valve does not work properly, over pressurization may occur, causing air tank rupture or an explosion. Daily pull the ring on the safety valve 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.
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. Operatre the air compressor in a dry, clean, cool, well ventilated area. The air compressor pump and case are designed to allow for proper 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. THESE PROCEDURES ARE REQUIRED BEFORE THE AIR COMPRESSOR IS PUT INTO SERVICE, AFTER REPLACING THE CHECK VALVE, AND WHEN THE PISTON OR THE CYLINDER SLEEVE IS REPLACED.
- A. Set the pressure switch lever to the “OFF” position.
- B. Plug the power cord into the correct branch circuit receptacle.
- C. Turn the drain valve (B) Fig. 4, opening it fully, to prevent air pressure build-up in the tank.
- D. Move the pressure switch lever to “ON/AUTO”. The compressor will start.
- E. Run the compressor for 15 minutes. Make sure the drain valve is open and there is no tank pressure build-up.
- F. After 15 minutes, close the drain valve by turning the knob. the air receiver will fill to cut-out pressure and the motor will stop. The compressor is now ready for use.
OPERATING PROCEDURES
Preparation for use:
