SAFETY GUIDELINES This manual contains information that relates to PROTECTING PERSONAL SAFETY and PREVENTING EQUIPMENT PROBLEMS. It is very important to read this manual carefully and understand it thoroughly before using the compressor. The symbols listed below are used to indicate this information. DANGER - POTENTIAL HAZARD THAT WILL RESULT IN SERIOUS INJURY OR LOSS OF LIFE WARNING - POTENTIAL HAZARD THAT COULD RESULT IN SERIOUS INJURY OR LOSS OF LIFE CAUTION - POTENTIAL HAZARD THAT MAY RESULT IN MODERATE INJURY OR DAMAGE TO EQUIPMENT
WARNING 1. RISK OF FIRE OR EXPLOSION. Do not spray a flammable or combustible liquid or paint near sparks, flames, pilot lights, or in a confined area. The spray area must be well-ventilated. Keep compressor at least 20' away from spray area. Do not carry and operate the compressor, or any other electrical device near the spray area. Never smoke when spraying. Use a minimum of 25' of hose to connect a spray gun to compressor. 2. RISK OF ELECTRIC SHOCK. Do not expose to rain. Store indoors. Hazardous voltage. Disconnect from power source before servicing. Compressor must be grounded, do not use grounding adaptors. RISK OF BURSTING. Make sure the regulator is adjusted so that the compressor outlet pressure is set lower than maximum operating pressure of the spray gun or tool. Before starting the compressor, pull the ring on the safety valve to make sure the valve moves freely. Drain water from tank after each use. Do not weld or repair tank. 3. RISK OF PERSONAL INJURY. Wear safety glasses. Never spray compressed air or material at self or others. Do not use compressed air for breathing. 4. RISK OF BURSTING. Check the maximum pressure rating in the manual or the serial tag label. The compressor outlet pressure must be regulated so that it does not exceed the maximum pressure rating. Relieve all pressure in the hose before removing or attaching accessories. 5. RISK OF BURSTING. Do not adjust the pressure switch or relief valve for any reason. They have been preset at the factory for this compressor’s maximum pressure. Tampering with the pressure switch or the relief valve may cause personal injury or property damage. 6. RISK OF BURNS. The pump and the manifold generate high temperatures. In order to avoid burns or other injuries, do not touch the pump, the manifold, or the transfer tube while the compressor is running. Allow the parts to cool down before handling or servicing. Keep children away from the compressor at all times. 7. 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. 8. RISK OF EYE INJURY. Wear ANSI Z87.1 approved safety goggles when using an air compressor. Do not point any nozzle or sprayer toward a person or any part of the body. Serious injury may occur if the spray penetrates the skin.
CAUTION 1. Pull the pressure relief valve ring every day in order to ensure that the valve is functioning properly. 2. The compressor must be located in a well-ventilated area for cooling, and must be a minimum of 12” (30 cm) away from the nearest wall. 3. Protect the air hose and the power cord from damage and puncture. Inspect them for weak or worn spots every week, and replace them if necessary. 4. Always wear hearing protection when using an air compressor. Failure to do so may result in hearing loss. 5. Do not operate the compressor if it is not in a stable position.

BASIC COMPRESSOR FEATURES A. ELECTRIC MOTOR: The motor is used to power the pump. It is equipped with a thermal overload protector and an automatic reset. If the motor overheats for any reason, the thermal overload protector will shut it down in order to prevent the motor from being damaged. The motor will automatically restart when it has cooled completely. B. AIR COMPRESSOR PUMP: The pump compresses the air and discharges it into the tank via the piston that moves up and down in the cylinder. C. PRESSURE SWITCH: This switch turns the compressor on and off. It is operated manually, and when it is in the ON position, it allows the motor to start if the pressure in the air tank is below the factory set cut-in pressure, and allows the motor to stop if the pressure in the air tank reaches the factory set cutout pressure. Be sure to set this switch to the OFF position when the compressor is not being used and before unplugging the compressor. D. PRESSURE RELIEF VALVE: This valve is used to prevent system failure by draining pressure from the system when it reaches a preset level if the pressure switch has not shut down the motor. It will pop open automatically, or it can be activated manually by pulling the ring on the valve. E. AIR PRESSURE REGULATOR: The regulator is used to adjust the pressure inside the line to the tool that is being used. Turn the knob clockwise to increase the pressure and counter-clockwise to decrease the pressure. WARNING：Do not exceed the tool’s maximum working pressure. F. TANK PRESSURE GAUGE: The gauge measures the pressure level of the air that is stored in the tank. It cannot be adjusted by the operator, and it does not indicate the pressure inside the line. G. REGULATED PRESSURE GAUGE: The gauge measures the regulated outlet pressure. H. AIR LINE OUTLET: The outlet is connected to the 1/4” (6.4 mm) NPT air hose. I.
AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the air tank after the compressor is shut off. WARNING：Do not attempt to open the drain valve when there is more than 10 PSI of air pressure in the tank.
J. AIR TANK: The tank is where the compressed air is stored. K. POWER CORD: This compressor should be used on a nominal 115 V grounded circuit. Use a power cord that is equipped with a grounding plug. Verify that the compressor is plugged into an outlet that has the same configuration as the plug (see Figure 1). Do not use an adaptor with this compressor. If the grounding instructions are not completely understood, or if there is any doubt as to whether the compressor is properly grounded, check with a licensed electrician Do not alter the plug in any way. If it will not fit into the outlet, have the proper type of outlet installed by a licensed electrician. DANGER：Improper installation of the grounding plug will result in a risk of electric shock. If it is necessary to repair or replace the cord or plug, do not connect the grounding wire to either flat blade terminal. The grounding wire is in the green coating.
