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 product. The symbols listed below are used to indicate this information. DANGER! Potential hazard that will result in serious injury or loss of life.
Page 10
DANGER! Potential hazard that will result in serious injury or loss of life. 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.
Page 11
• 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.
Page 12
WARNING! Potential hazard that could result in serious injury or loss of life. • The compressor must be located in a well-ventilated area for cooling, and must be a minimum of 12” (31 cm) away from the nearest wall. • Protect the air hose and the power cord from damage and puncture.
Extension cords As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible product damage. Refer to the table to determine the required minimum wire size.

Compatible compressor and air tool - proper usage and operation ® Always ensure the use of appropriately matched air tools with your Mastercraft Air Compressor. Be sure that the air compressor being used can supply the appropriate volume, pressure and delivery rate of air to the tool(s) without running continuously.
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 cut-out pressure.

Assembly • 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.

CAUTION! Potential hazard that may result in moderate injury or damage to equipment. • Use a dedicated circuit. The compressor will use the full capacity of a typical 15 A household circuit. If any other electrical devices are drawing from the compressor’s circuit, the air compressor may fail to start. Low 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.
Page 22
Start-up procedure WARNING! Potential hazard that could result in serious injury or loss of life. • Risk of bursting. Too much air pressure causes a hazardous risk of bursting. Check the manufacturer's maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating.
4. Check and verify the motor oil level in the pump. fig L 5. Close the tank drain valve (1). Plug-in (fig L) the power cord (2) 6. Set the pressure switch to the ON position and allow the tank pressure to build.
General maintenance WARNING!
