PREPARATION

UNPACKING THE COMPRESSOR

• Unpack the air compressor unit. Inspect the unit for damage. If the unit has been damaged, contact the retailer immediately.
• Check the air compressor’s identification label to ensure that you have purchased the intended model and that it has the required pressure rating for its intended use.
• The carton should contain the air compressor and owner’s manual.
• POSITIONING OF THE AIR COMPRESSOR (FIG.1)
• Position the air compressor (1) near an electrical outlet (2).
• The compressor must be at least 12”(31cm) from any wall (3) or obstruction, in a clean, well-ventilated area to ensure sufficient airflow and cooling.
• Place the air compressor on the floor or a hard, level surface. The air compressor must be level to ensure proper drainage of the moisture in the tank.
• CONNECT THE AIR HOSE TO THE COMPRESSOR (FIG.2)
• Connect the air hose (1) to the compressor’s quick coupler (2) with the quick connector (3).
• NOTE: Air hose and quick connector are not provided and need to be purchased separately. Apply PTFE tape on all the threads to prevent air leakage.
• WARNING! High-pressure air could result in death or serious injury. Never operate above the maximum operating pressure of the spray gun or tool.
• WARNING! Hot compressor surfaces could result in serious injury. Allow the compressor to cool before touching it.
• NOTE: If the pump has been transported or turned upside down (even partially), allow the pump to sit in a normal, upright position for approximately 10 minutes before starting.
• WARNING! Risk of serious eye injury from moisture and debris. Always wear CE safety goggles when opening the drain valve.
• WARNING! High-pressure air could result in death or serious injury. Shut off the unit, unplug, and release air pressure before servicing.
• CAUTION: High-pressure air containing water condensation could result in minor or moderate injury. Do not spray at any person.

BREAK IN THE PUMP

• Set the pressure switch to the OFF position (fig.3).
• Open the tank drain valve by turning it counter-clockwise to permit the air to escape and prevent air pressure build-up in the air tank during the break-in period (fig.4).
• Turn the air pressure regulator knob clockwise until it stops (fig 5).
• Plug in the power cord
• Use a dedicated circuit. The compressor will use the full capacity of a typical 10A household circuit.
• If any other electrical devices are drawing from the compressor’s circuit, the air compressor may fail to start voltage or an overloaded circuit can result in sluggish starting that causes the motor overload protection system or circuit breaker to trip, especially in cold conditions. Disconnect the power cord only after the break-in process has been completed, otherwise, the motor might get damaged.
• Set the pressure switch to the ON position. The compressor will start. Run the compressor for 30 minutes. If it fails, turn it off immediately.
• NOTE: Breaking in the unit is only required before first use.
• After 30 minutes, turn off the pressure switch.
• Close the tank drain valve by turning it clockwise (fig 4).
• Set the pressure switch to the ON position. The air receiver will fill to “cut-out” pressure and then the compressor’s motor will stop. The compressor is now ready for use.

BEFORE EACH START-UP

• Set the pressure switch to the OFF position (fig.3).
• Turn the air pressure regulator knob counter-clockwise until it stops (fig.5).
• Attach hose and accessories (sold separately).

HOW TO START

• Close the tank drain valve (fig.4).
• Plug in the power cord.
• Set the pressure switch (fig.3) to the ON position and allow the tank pressure to build.
• The motor will stop when tank pressure reaches cutout pressure.
• Turn the air pressure regulator knob (fig.5) clockwise until the desired pressure is reached.
• The compressor is ready for use.

HOW TO SHUT DOWN

• Set the pressure switch to the OFF position (fig.3).
• Unplug the power cord.
• Set the tank drain valve to ON to ensure the tank is drained (fig.4).

MAINTENANCE

• WARNING! Disconnect from all energy supplies before servicing.
• WARNING! Display warning signs against reconnection whilst the compressor is being repaired such as:
• WARNING! Air contaminants taken into the compressor will affect optimum performance.
• Example: Body filler dust or paint overspray will clog the pump intake filter and may cause internal damage to pump/motor components.
• Please note that any parts damaged by any type of contamination will not be covered by warranty.

DAILY MAINTENANCE
Drain the tank. Through normal operation of your air compressor, condensation of water will accumulate in the tank. To prevent corrosion of the tank from the inside, condensation must be drained at the end of every workday. Be sure to wear protective goggles.
Relieve the air pressure in the system then open the drain valve on the bottom of the tank to drain. Under cold conditions, it is especially important to drain the tank after each use to reduce the chance of problems resulting from the freezing of condensation water. NOTE: Refer to 7.5 on how to drain the tank. Pressure relief valve. Loosen the knob at the top of the safety valve to ensure normal exhaust. Tighten it again and remove any debris.

MONTHLY MAINTENANCE
Test for leaks. Check that all connections are tight. Small leaks in the tank, hoses, connections, or transfer tubes will substantially reduce the air compressor and tool performance. Spray a small amount of soapy water around the area of suspected leaks with a spray
bottle. If bubbles appear, repair, replace, or reseal the faulty component. Do not over-tighten any connections.

BEFORE STORING
Before storing the air compressor:

• Drain tank.
• Use an air blow gun to clean all dust and debris from the compressor.
• Disconnect and wind up the power cord.
• Clean the ventilation openings on the motor enclosure with a damp cloth.
• Drain all moisture from the tank.
• WARNING! Storage covers could cause a fire resulting in death or serious injury.
• DO NOT place a storage cover over a hot air compressor.
• Let the equipment cool for a sufficient time before placing the cover on the equipment.

STORAGE

• Store the air compressor in a clean and dry location.
• In cold weather, store the compressor in a warm building when it is not in use.
• This will reduce problems related to starting the motor and the freezing of water condensation.

HOW TO DRAIN TANK

• Set the pressure switch to the OFF position.
• Unplug the power cord.
• Turn the air pressure regulator knob counter-clockwise to set the outlet pressure to zero.
• Place a suitable container under the unit to catch water.
• Slightly tilt the unit and turn the drain valve counter-clockwise to open.
• After the water has been drained, close the drain valve(clockwise). The air compressor can now be stored.

TROUBLESHOOTING
