We use the symbols below to help you recognize this information.POTENTIAL HAZARD THAT WILL RESULT IN SERIOUS INJURY OR LOSS OF LIFEPOTENTIAL HAZARD THAT COULD RESULT IN SERIOUS INJURY OR LOSS OF LIFEPOTENTIAL HAZARD THAT MAY RESULT IN MODERATE INJURY OR DAMAGE TO EQUIPMENT1. RISK OF EXPLOSION OR FIRE.Never spray flammable liquids in a confined area. It is normal forthe motor and pressure switch to produce sparks while operating. If sparks come into contact with vapors from gasoline or other solvents, they may ignite and cause fire or explosion. Do not smoke while spraying. Do not spray where sparks or flame are present. Keep compressor as far from spray area as possible. Always operate the compressor in a well-ventilated area.2.RISK OF ELECTRIC SHOCK. A licensed electrician in accordance with all local and national codesmust install all wirings. To avoid electric shock, NEVER use an electric air compressor outdoors when it is raining or on a wet surface.3. RISK OF BURSTING. Rust can weaken the tank.Drain the condensed water from the tank aftereach use to reduce rusting. Welding or modifications on the air tank can severely impair tank strength and cause an extremely hazardous condition. So DO NOT weld, drill or modify the air tank of this compressor. If a leak is detected in the tank, replace the tank right away.4. RISK OF INJURY. ALWAYS shut off the compressor, remove the plug from the outlet and bleed allpressure from the system before servicing the compressor or when the compressor is not in use. Do NOT use the unit with the shrouds removed. Contact moving parts could cause serious injury.5. RISK OF BURSTING. Check the maximum pressure rating in the manual or the serial tag label.Compressor outlet pressure must be regulated so as to never exceed the maximum pressure rating. Relieve all pressure through the hose before removing or attaching accessories.6. RISK OF BURSTING. DO NOT adjust the pressure switch or relief valve for any reason. They havebeen preset at the factory for the maximum pressure of this unit. If the pressure switch or the relief valve are tampered with, personal injury or property damage may occur.7. RISK OF BURNS. Pump and manifold generate high temperature. To avoid burns or other injuries,DO NOT touch the pump, manifold or transfer tube while the unit is running. Allow the parts to cool before handling or servicing. Keep children away from the compressor at all times.8. RISK TO BREATHING. Be certain to read all labels when you are spraying paints or toxic materials,and follow the safety instructions. Use a respirator mask if there is a chance of inhaling anything you are spraying. Also, NEVER directly inhale the compressed air produced by a compressor.9. RISK OF EYE INJURY. ALWAYS wear ANSI Z87.1 approved safety goggles when using an aircompressor. NEVER point any nozzle or sprayer toward a person or any part of the body. If the spray penetrates the skin, serious injury may occur.1. Pull the pressure relief valve ring daily to ensure that the valve is functioning properly.2. The unit must be kept a minimum of 12 inches from the nearest wall, in a well-ventilated area forcooling.3. Protect the air hose and electric cord from damage and puncture. Inspect them weekly for weak orworn spots and replace if necessary.4. Always wear hearing pretection when using an air compressor. Failure to do so may result inhearing loss.5. Operation of the unit should always be in a position that is stable. Never use the unit on a rooftop orelevated position that could allow the unit to fall or be tipped over.-Page 3-B A CDEFGHIJK A--------ELECTRIC MOTOR B--------AIR COMPRESSOR PUMP C--------PRESSURE SWITCH D--------PRESSURE RELIEF VALVE E--------AIR PRESSURE REGULATOR F--------TANK PRESSURE GAUGE G--------REGULATED PRESSURE GAUGE H--------AIR LINE OUTLET I---------AIR TANK DRAIN VALVE J---------AIR TANK K--------POWER CORD-Page 4-A. ELECTRIC MOTOR: The motor is used to power the pump. It has a thermal overload protector and anautomatic reset. If the motor overheats for any reason, the thermal overload protector will shut it down to prevent the motor from being damaged. The motor will automatically restart when it completely cools.B. AIR COMPRESSOR PUMP: The pump is used to compress the air and discharge it into the tank viathe piston moving up and down in the cylinder.C. PRESSURE SWITCH: The switch is used to start or stop the air compressor. It is operated manually.When in ON position, it allows the motor to start when the air tank pressure is below the factory set cut-in pressure and allows the motor to stop when the air tank pressure reaches the factory set cut-out pressure. ALWAYS set this switch to OFF when the unit is not being used, and before unplugging the unit.D. PRESSURE RELIEF VALVE: The valve is used to prevent system failures by relieving pressure fromthe system when the pressure reaches the preset level while the pressure switch does not shut down the motor. It will pop open automatically or you can pull the ring on the valve to make it.E. AIR PRESSURE REGULATOR: The regulator is used to adjust line pressure to the tool you are using.Turn the knob clockwise to increase pressure and counterclockwise to decrease pressure.Never exceed the maximum working pressure of the tool.F. TANK PRESSURE GAUGE: The gauge is used to measure the pressure level of the air stored in thetank. It is not adjustable by the operator, and does not indicate line pressure.G. REGULATED PRESSURE GAUGE: The gauge is used to measure the regulated outlet pressure.H. AIR LINE OUTLET: The outlet is used to connect 1/4” NPT air hose.I. AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the air tank after the unit isshut off.Never attempt to open the drain valve when over 10 PSI of air pressure is in the tank.J. AIR TANK: The tank is used to store the compressed air.K. POWER CORD: This product is for use on a nominal 115 volt circuit and should be grounded. A cordwith a grounding plug, as K showed, shall be used. Make sure that the product is connected to an outlet having the same configuration as the plug (see Figure 1). No adapter should be used with this product.Check with a licensed electrician if the grounding instructions are not completely understood, or if in doubt as to whether the product is properly grounded. Do not modify the plug provided. If it will notfit the outlet, have the proper outlet installed by a licensed electrician.Improper installation of the grounding plug will resultis necessary, do not connect the grounding wire to either flat blade terminal. The grounding wire is in green outer surface.Figure 1Grounded outlet 115V/13 AGrounding Pin Plug -Page 5-1. Unpack the air compressor and inspect the unit fordamage and parts. If the unit has been damaged or some parts are missing, contact the agent immediately.2. Check the serial tag label to ensure that it has therequired pressure rating for its intended use.3. Take out two(2) wheels(A), two(2) bolts(B), four(4)washers(C), two(2) nuts(D) from the bag and install them on the foot section of the tank. (See Figure 2)4. Unpack the smaller plastic bag with the air filterincluded and have the air filter (A) assembled on the pump. (See Figure 3)5. Locate the compressor according to the followingguidelines:a. Set the compressor in a position near agrounded electrical outlet.b. The compressor must be at least 12 inchesaway from any wall or obstruction, in a clean,well-ventilated area, to ensure sufficient airflow and cooling.c. The compressor must be level to ensureproper drainage of the moisture in the tank.d. In cold weather, store the compressor in aheated building when not in use. This willreduce problems with motor starting andfreezing of water condensation.6. Connect an air hose with a 1/4” NPT fitting kit to thecompressor air line outlet. Figure 2DCAB-Page 6-Figure 3NOTE: The pump is shipped WITHOUT oil. Before starting, thebreak-in oil provided in an oil bottle should be poured in the pump through the oil nozzle.
