RISK OF EXPLOSION OR FIRE WHAT CAN HAPPEN 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. HOW TO PREVENT IT Always operate the compressor in a well ventilated area free of combustible materials, gasoline or solvent vapors. If spraying flammable materials, locate the compressor at least 20 feet away from the spray area. An additional length of hose may be 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. RISK OF BURSTING WHAT CAN HAPPEN 1. Failure to properly drain condensed water from the tanks, causing rust and thinning of the steel tank. 2. Modifications or attempted repairs to the tanks. 3. Unauthorized modifications to the unloader valve, safety valves or any other components which control tank pressure. 4. Excessive vibration can weaken the air tanks and cause rupture or explosion. Attachments & Accessories; Exceeding the operating pressure of air tools can cause them to explode. HOW TO PREVENT IT Drain tanks daily or after every use. If a tank developes a leak, replace tank or get a new air compressor. Never drill into, weld or make any modifications to the tanks or their attachments. The tanks are 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. RISK OF BURNS WHAT CAN HAPPEN Touching exposed metal such as the compressor head or outlet tubes, can result in serious burns. HOW TO PREVENT IT Never touch any exposed metal parts on compressor during or immediately after operation. The compressor will remain hot several minutes after use. Do not reach around protective shrouds or attempt maintenance until the compressor has cooled down completely. RISK OF PROPERTY DAMAGE WHEN TRANSPORTING COMPRESSOR WHAT CAN HAPPEN Oil can leak or spill and could result in fire or breathing hazard, serious injury or death can result. Oil leaks will damage carpet, paint or other surfaces in vehicules or trailers. HOW TO PREVENT IT Always place compressor on a protective mat when transporting to protect against damage to vehicule from leaks. Remove compressor from vehicule immediately apon arrival.

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 120V, WITH A MINIMUM 15-AMP. BRANCH CIRCUIT. 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 compressor is equipped with a cord having an equipment grounding 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. 120V OPERATION As received from the factory, your compressor is ready to run for 120V 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. FIGURE 1 FIGURE 2 EXTENSION CORDS The use of any extension cord will cause some loss of power. IT IS RECOMMENDED TO USE A LONGER AIR HOSE INSTEAD OF AN EXTENSION CORD. If you do not have a choice, use the table in Fig.2 to determine the minimum wire size (A.W.G-American 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 compressor motor. Refer to Fig.2 for wire length and size.

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. Note: (A) Fig.5 is not a check valve, it is a two way connector which allows you to connect an air hose and air tool to the detachable tank. ON/AUTO-OFF SWITCH (B) FIG.3. Turn this switch ON by raising lever upwards to provide power to the automatic pressure switch and lower lever to turn compressor OFF. 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 (B) FIG.4. 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 (D-FIG.4). The main 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 GAUGES (A-FIG.4, B-FIG.5). The main tank pressure gauge (A) Fig.4 indicates the reserve air pressure in both tanks (if detachable tank is connected). The detachable tank pressure gauge (B) Fig.5 indicates the reserve air pressure in the detachable tank only. DRAIN VALVES (A & B FIG.6). The drain valves are located at the base of each air tank and are used to drain condensation from the tanks to prevent corrosion, should be done at the end of each use. QUICK CONNECT COUPLERS (C-FIG.4). Connect up to 2 air tools. DETACHABLE TANK AIR PRESSURE CUT-OFF VALVE (C) FIG. 3. Close this cut-off valve before disconnecting detachable tank. When detachable tank is connected to compressor, this cut-off valve must be open to allow air pressure to build inside detachable tank. DETACHABLE TANK AIR SUPPLY HOSE (D-FIG. 5). The air supply hose must be connected to detachable tank quick connect coupler to allow air pressure to build. Disconnect this air supply hose when detaching upper tank is needed. MOTOR THERMAL OVERLOAD PROTECTOR (RESET (A) FIG. 7). 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 (A). 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 VALVES (C-FIG.5, C-FIG.6). If the pressure switch does not shut off the air compressor at its “Cut-Out” pressure setting, the safety valves will protect against high pressure by “popping out” at their factory set pressure (slightly higher than the pressure switch “Cut-Out” setting). WARNING!: If the safety valves don’t work properly, over pressurization may occur, causing air tank rupture or an explosion. Daily pull the ring on each safety valve to make sure that they operate freely. If a valve is stuck or does not operate smoothly, it must be replaced with the same type of valve before operating again. FIGURE 3 FIGURE 4 FIGURE 5 FIGURE 6 FIGURE 7

ASSEMBLY AND LOCATION OF THE AIR COMPRESSOR Your compressor comes almost completely assembled, the air filter must be installed and the oil cap must be replaced with the oil breather cap (A) Fig.9. Operate 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. Seperate air transformers which combine the function of air regulation, moisture and dirt removal should be used where applicable. BREAK-IN PROCEDURES NOTE: SERIOUS DAMAGE MAY RESULT IF THE FOLLOWING BREAK-IN INSTRUCTIONS ARE NOT CLOSELY FOLLOWED. THIS PROCEDURE IS REQUIRED BEFORE THE AIR COMPRESSOR CAN BE PUT INTO SERVICE, AFTER REPLACING THE CHECK VALVE, AND WHEN THE PISTON OR THE CYLINDER SLEEVE IS REPLACED. 1. Fill crankcase with oil to the red dot of oil sight glass as described in “Changing Oil” in the maintenance section on the following page. 2. Set the pressure switch lever to the “OFF” position. 3. Plug the power cord into the correct 120V branch circuit receptacle. 4. Fully open the drain valves (A & B) Fig.6, by turning them counterclockwise, to prevent air pressure build-up in the tanks. 5. Move the pressure switch lever to “ON/AUTO”. The compressor will start. 6. Run the compressor for 15 minutes. Make sure the drain valves are open and there is no tank pressure build-up by watching the tank pressure gauge. 7. After 15 minutes, close the drain valves by turning them clockwise. 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: 1. Before attaching an air hose or accessories, make sure the OFF/AUTO lever is set to “OFF” and the air regulator is closed. Once this is done, you can now attach a hose or an accessory. WARNING: Too much air pressure causes a hazardous risk of bursting. Check the manufacturer's maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating of the tool being used. 2. Turn the “ON/AUTO-OFF” lever to “ON/AUTO” and allow tank pressure to build. Motor will stop when tank pressure reaches “Cut-Out” pressure. 3. Open the regulator by turning it clockwise. Adjust the regulator to the correct pressure setting. The compressor is ready for use. 4. Always operate the air compressor in well ventilated areas; free of gasoline or other solvent vapors. Do not operate the compressor near the spray area. After Use: 5. Set the “ON/AUTO-OFF” lever to “OFF”. 6. Turn the regulator counterclockwise to set the outlet pressure to zero. 7. Disconnect the air tool or accessory. 8. Pull ring on safety valves (C) Fig.5 & Fig.6, allowing air to bleed from the tanks until tank pressure is approximately 20 psi. Release safety valve rings. 9. Drain water from air tanks. Turn drain valves (A) Fig. 5 & (B) Fig.6, counterclockwise to open. WARNING!: WATER WILL CONDENSE IN THE AIR TANKS. IF NOT DRAINED REGULARLY, WATER WILL CORRODE AND WEAKEN THE AIR TANKS CAUSING A RISK OF AIR TANK RUPTURE. NOTE: If a drain valve is plugged, pull ring on corresponding safety valve and hold until air pressure has been released. The plugged valve can then be removed, cleaned, and reinstalled. 10. After the water has been completely drained, turn drain valves to close. The air compressor can now be stored. DISCONNECTING/USING DETACHABLE UPPER TANK 1. Lift the retractable transport handle away from the upper tank. 2. Position the air supply valve (C) Fig.3 to the off position as shown. 3. Disconnect the air fitting (A) Fig.8 from the quick connect coupler (B). 4. Unhook the retaining straps (C) to release the upper tank. The upper tank has now been disconnected properly. Tank can now be used remotely using the hose with tire inflator (D) or an air hose (with air tool connected to it) can be connected to the quick connect coupler (B). Note: This detachable tank provides unregulated air pressure. After Use: 5. Reinstall upper tank on compressor frame, secure tank with retaining straps, reconnect the air supply fitting to the quick connect coupler and reposition the air supply valve to the on position.

Daily or before each use: 1. Check oil level. The oil level should be centered with the red dot which appears in the oil sight glass (C) Fig.9. 2. Drain condensation from tanks. 3. Check for any unusual noise or vibration. 4. Be sure all nuts and bolts are tight. Monthly 1. Inspect air system for leaks by applying soapy water to all joints. Tighten those joints if leakage is observed. 250 hours or six months (whichever comes first) 1. Change compressor oil. See following instructions. 2. Replace oil more often if compressor is used near paint spraying operations or in dusty environments. CHANGING OIL To change oil, oil must be drained from the crank case by unscrewing and removing oil sight glass (C) Fig.9. Drain oil and replace oil sight glass. To fill the crank case with oil, first unscrew and remove oil breather cap (A), pour approx. 200ml of air compressor oil (SAE 10W30 or SAE 10W20 weight non-detergent oil) into crank case oil opening (B) until the oil level reaches the red dot at the center mark of the oil sight glass. Secure oil breather cap (A). KEEP TOOL CLEAN Periodically blow out all air passages with dry compressed air. Clean all plastic parts with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material. CAUTION: Wear safety glasses while using compressed air. FAILURE TO START Should your compressor fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line. STORAGE 1. Set the “ON/AUTO-OFF” lever to “OFF”. 2. Turn the regulator counterclockwise to set the outlet pressure to zero. 3. Remove the air tool or accessory . 4. Pull ring on safety valves (C) Fig.5, Fig.6, allowing air to bleed from the tanks, until tank pressure is approximately 20psi. Release safety valves. 5. Drain water from air tanks. Turn drain valves (A&B) Fig.6, counterclockwise, to open. NOTE: If a drain valve is plugged, pull ring on corresponding safety valve and hold until air pressure has been released. The valve can then be removed, cleaned, and reinstalled. 6.
