This product must be grounded. In the event of an electrical short circuit, grounding reduces risk of electrical shock by providing an escape wire for electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding wire with an appropriate grounding plug. Plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Danger! Improper use of grounding plug can result in a possible risk of electrical shock!

Danger!

Do not use a grounding adapter with this product! If repair or replacement of power cord or plug is necessary, do not connect grounding wire to either flat blade terminal. The wire with insulation having an external surface that is green (with or without yellow stripes) is the grounding wire.

Danger!

Never connect green (or green and yellow) wire to a live terminal. Check with a qualified electrician or service man if grounding instructions not completely understood or in doubt as to whether product is properly grounded. Never modify the plug receptacle privately; if there are not fitting outlet, make

proper outlet installed by a qualified electrician.

Warning! Local electrical wiring codes differ from area to area. Source wiring, plug and protector must be rated for at least the amperage and voltage indicated on motor nameplate, and meet all electrical codes for this minimum. Use a slow blow fuse or a circuit breaker.

Caution!

Overheating, short circuiting and fire damage will result from inadequate wiring. NOTE: 230 volt, 5 amp units can be operated on a 230 volt circuit under the following conditions:

No other electrical appliances or lights are connected to the same branch circuit.

Voltage supply is normal.

Circuit is equipped with a 5 amp circuit breaker or a 15 amp slow blow fuse. If these conditions cannot be met or if disconnection of current protection device occurs, it may be necessary to operate compressor from a 230 volt, 5 amp circuits.

Operation Pressure Switch Auto/Off Switch-In the “AUTO” position, the compressor shuts off automatically when tank pressure reaches the maximum preset pressure (0.8Mpa) and runs automatically when tank pressure reaches the minimum preset pressure (about 0.6Mpa). In the “OFF” position, the compressor will not operate. This switch should be in the “OFF” position when connecting or disconnecting the power cord from the electrical outlet or when changing air tools. Regulator The regulator uses to adjust the pressure of outlet to fitting air-power tools. Safety Valve It releases compressed air automatically when the pressure in the tank exceeds allowing pressure. Discharge Pipe Discharge pipe connects the pump head and checks valve. It is hot when the compressor is running. To avoid grievous burn, never touch discharge Pipe. Check Valve Check valve is a one-way valve, allowing compressed air go ahead to the tank, but prevents compressed air in the tank back to the pump. Handle and wheels Designed in order to move the compressor easily.

Warning!

Never use the handle on wheeled units to lift the unit completely off the ground. Drain Valve This valve is located at the bottom of the tank. Used to exhaust water from the tank. Make sure the gauge pressure of the tank is below 1 Bar, open the drain valve to exhaust water from tank, close it tightly. This action should be done every week.

Add oil Air compressor oil is suggested to use. Keep the oil’s level in the red cycle of oil glass.

SAE30 oil is suggested to use. Break-in procedure

Caution!

Do not attach air chuck or other tools to the outlet until unit have been checked and start procedure has been completed.

IMPORTANT: Do not operate compressor before reading instructions, otherwise damage may result. 1. Turn regulator fully clockwise to open airflow. 2. Turn switch to OFF position and plug in power cord. 3. Turn switch to AUTO position and run unit for 30 minutes to run the pump parts. 4. Turn regulator knob fully counterclockwise. Compressor will build to maximum

preset pressure and shut off. 5. Turn regulator knob clockwise to bleed

off air. Compressor will restart at a preset pressure (about 6 bar).

6. Turn regulator knob counterclockwise to shut off the air and turn switch to off position.

7. Attach chuck or other tool to outside. Open the pressure switch to AUTO position, the compressor starts work and pumps air into the tank. It shuts off automatically when unit reaches its maximum preset pressure. In the OFF position, the pressure switch cannot function and the compressor will not operate. Make sure switch is in OFF position when connecting or disconnecting power cord to electrical receptacle.

Moisture in compressed air Moisture in the air will change to water when air is compressed or temperature is drop. When humidity is high or when a compressor is in continuous use for a long time, water will collect in the tank. If you use a paint spray or sandblast gun, moisture will be carried from the tank through the hose, and out of the gun as water mixed with the spray material. IMPORTANT: This condensation will cause water spots in a paint job, especially when spraying other than water based paints. If sandblasting, it will cause the sand to case and clog the gun rendering it ineffective. A dry filter in the air line, located nearby the gun as possible, will help eliminate this moisture. Safety valve

Warning!

Do not remove or attempt to adjust the safety valve! Safety valve should be checked under pressure occasionally by pulling the ring by hand. If air leakage after ring has been released, or valve is stuck and cannot be actuated by ring, it MUST be replaced.

Regulator 1. Regulator adjusts air pressure to fit an air-operated tool or paint spray gun. 2. Adjust outlet air pressure by turn the knob Pressure gauge There are 1 or 2 gauges on this type of compressor, one shows pressure in tank and another one (if there are 2 gauges) shows outlet’s pressure after regulator.

Thermal overload protector

Caution! This compressor is equipped with an automatic reset thermal overload protector, which will shut off motor if it becomes overheated. If thermal overload protector shuts motor OFF frequently, look for the following causes. 1. Low voltage. 2. Clogged air filter. 3. Lack of proper ventilation.

Caution!

If the thermal overload protector is actuated, the motor must be allowed to cool down before start-up is possible. The motor will automatically restart without warning if left plugged into electrical outlet and unit is turned on.
