PSIG or PSI: Pounds per square inch gauge. CUT-IN PRESSURE: While the motor is off, air tank pressure drops as you continue to use your accessory or air tool. When the tank pressure drops to a certain low level the motor will restart automatically. The low pressure at which the motor automatically restarts is called “cut-in pressure.” CUT-OUT PRESSURE: When you turn on your air compressor and it begins to run, air pressure in the air tank begins to build. It builds to a certain high pressure before the motor automatically shuts off - protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts off is called “cut-out pressure.” COD CERTIFICATION: Products that bear one or more of the following marks: UL, CUL, ETL, CETL have been evaluated by OSHA certiﬁed independent Safety laboratories and meet the applicable Underwriters Laboratories Standards for safety.

SCFM @ 40 PSIG SCFM @ 90 PSIG Cut-In Cut-out Bore Stroke Voltage/Hertz/Phase Minimum Branch Circuit * Fuse Type Amperage at Max. Load Tank Size * A circuit breaker is preferred. Use only a fuse or circuit breaker that is the same rating as the branch circuit on which the air compressor is operated. If the air compressor is connected to a circuit protected by fuses, use dual element time delay fuses. 6 DESCRIPTION OF OPERATION Air Compressor Pump: To compress air , the piston moves up and down in the cylinder. On the down stroke, 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 (B, Fig. 1): When the air compressor is operating, the check valve is “open”, allowing compressed air to enter the air tank. When the air compressor reaches “cut-out” pressure, the check valve “closes”, allowing air pressure to remain inside the air tank. B ON/AUTO-OFF Switch (C, Fig.2):Turn this switch ON to provide power to the automatic pressure switch and OFF to remove power at the end of each use. C Pressure Switch (C, Fig. 2): The pressure switch automatically starts the motor when the tank pressure drops below the factory set “cut-in” pressure. It stops the motor when the air tank pressure reaches the factory set “cut- out” pressure. G Fig. 1 Fig. 2 Fig. 3 Regulator (D, 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 pressure setting, always approach the desired pressure from a lower pressure. When reducing from a higher to a lower setting, ﬁrst reduce to pressure less than that desired, and then bring it up to the desired pressure. Depending on the air requirements of each particular accessory, the outlet regulated air pressure may D F have to be adjusted white operating the accessory. Outlet Pressure Gauge (E, Fig. 4): The outlet pressure gauge indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure. See “Operating Procedures”. K E 7 Fig. 4 ENGLISH Tank Pressure Gauge (F, Fig. 4): 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 (G, Fig. 3): 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: 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. 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 (K, Fig. 4): If the pressure switch does not shut off the air compressor at its cut-out pressure setting, the safety valve will protect against high pressure by “popping out” at its factory set pressure (slightly higher than the pressure switch cut-out setting). If the safety valve does not work properly, over-pressurization may occur, causing the air tank to rupture or an exploded. The ring on the safety valve should be pulled daily to make sure that the safety valve operates freely,if the valve is stuck or does not operate smoothly, it must be replaces with the same type of valve. Overload protection(Fig. 5) This compressor has a reset Overload overload reset button that will restart the motor protection after it shuts off due to overloading or low voltage. If the motor stops during operation: 1. Turn the ON/OFF switch to the OFF position. 2. Wait about five minutes for the motor to cool. 3. Push in on the reset button. Fig. 5 4. Turn the switch to the ON position. TO PREVENT AN ACCIDENTAL START-UP IF THE RESET BUTTON IS PUSHED, THE ON/OFF SWITCH SHOULD BE IN THE OFF POSITION AND THE PLUG SHOULD BE REMOVED FROM THE POWER SOURCE WHILE COOL DOWN TAKES PLACE. INSTALLATION AND BREAK-IN PROCEDURES LOCATION OF THE AIR COMPRESSOR Your compressor comes to you completely assembled and ready for use. Operate the air compressor in a dry, clean, cool, and 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 8 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. VOLTAGE AND CIRCUIT PROTECTION See SPECIFICATIONS Section of this manual. GROUNDING INSTRUCTIONS The air compressor is equipped with a cord having a grounded wire with an appropriate grounding plug. The plug must be used with an outlet that has been installed and grounded in accordance with all local codes and ordinances. The outlet must have the same conﬁguration as the plug. DO NOT USE AN ADAPTOR. IMPROPER GROUNDING CAN RESUL RESULT T IN SEVERE ELECTRICAL SHOCK. Inspect the plug and cord before each use. Do not use if there are signs of damage. Do not modify the plug that has been provided. If it does not ﬁt the available outlet, the correct outlet should be installed by a qualiﬁed electrician. If these grounding instructions are not completely understood, or if in doubt as to whether the compressor is properly grounded, have the installation checked by a qualiﬁed electrician. EXTENSION CORDS Use extra air hose instead of an extension cord to avoid voltage drop and power loss to the motor. If an extension cord must be used, be sure it is: • A 3-pronged extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that will accept the plug on the compressor. • In good condition. • No longer than 50'. 14 gauge (AWG) or larger. (Wire size increases as gauge number decreases.) 12 AWG, 10 AWG and 8 AWG may also be used. DO NOT USE 16 AWG or SMALLER. 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 air driven device. Separate air transformers which combine the function of air regulation, moisture and dirt removal should be used where applicable. LUBRICATION The bearings in this unit are sealed, containing sufﬁcient lubricant to last their lifetime. No other lubrication is required. BREAK-IN PROCEDURES NOTE: Serious damage may result if the following break-in instructions are not closely followed. 9 This procedure is 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 (G, Fig. 3), 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 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: 1. Before attaching air hose or accessories, make sure the OFF/AUTO lever is set to “OFF” and the air regulator is closed. 2. Attach hose and accessories. TOO MUCH AIR PRESSURE CAUSES A HAZARDOUS RISK OF TANK EXPLOSION. CHECK THE MANUFACTURER’S MAXIMUM PRESSURERATING FOR AIR TOOLS AND ACCESSORIES. THE REGULATOR OUTLET PRESSURE MUST NEVER EXCEED THE MAXIMUM PRESSURE RATING OF THE TOOL BEING USED. 3. Turn the OFF/AUTO lever to “AUTO” and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure. 4. Open the regulator by turning it clockwise. Adjust the regulator to the correct pressure setting. The compressor is ready for use. 5. 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: 6. Set the “OFF/AUTO” lever to “OFF”. 7. Turn the regulator counter clockwise to set the outlet pressure to zero. 8. Remove the air tool or accessory. 9. Pull ring on the safety valve (K, Fig. 4), allowing air to bleed from the tank until tank pressure is approximately 20 PSI. Release safety valve ring. 10. Drain water from air tank. Turn the drain valve (G, Fig. 3), counter clockwise, to open. WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED, WATER WILL CORRODE AND WEAKEN THE AIR TANK CAUSING A RISK OF AIR TANK RUPTURE. NOTE: If drain valve is plugged, pull the ring on the safety valve (K, Fig. 4), and hold until all air pressure has been released. The valve can then be removed, cleaned, and reinstalled. 10 11. After the water has been completely drained, turn drain valve to close. The air compressor can now be stored. MAINTENANCE KEEP CLEAN Periodically blow out all air passages with dry compressed air.
