4 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. WARNING! Potential hazard that could result in serious injury or loss of life.
SAFETY GUIDELINES 5 DANGER! Potential hazard that will result in serious injury or loss of life. • Keep bystanders, children and visitors away from the work area while operating the compressor. Do not allow children to handle the compressor. Distractions can affect the control of the compressor. • Never point any nozzle or sprayer toward yourself, other people or animals. Fast moving air may spread dust and debris which are harmful.
• Risk of electric shock: Do not expose the compressor to rain or wet conditions. Store it indoors. Make sure the power supply outlet and grounding wire are grounded properly. Keep the power cord away from heat, oil, sharp edges, moving parts, chemical spills, solvents and wet floors. • Risk of bursting: Make sure the safety relief valve installed in the tank complies with ASME code and has a setting not higher than maximum working pressure. Never attempt to adjust the safety relief valve.
7 SAFETY GUIDELINES CAUTION! Potential hazard that may result in moderate injury or damage to equipment. • Do not wear watches, rings, bracelets or loose clothing when using the compressor. Keep your hair, clothing and gloves away from moving parts. • Use the compressor only for its intended purpose. Do not alter or modify the compressor from its original design or function. • Always operate the compressor in a stable, secure position to prevent accidental movement. • Do not misuse the power cord.
8 • The air tool is not a toy. Careless and improper use of the air tool may result in a serious accident. • Never leave or store the tool with the air hose attached to avoid accidental starting of the tool and serious personal injury. • Protect the air hose from damage or puncture. Keep the air hose away from sharp objects, chemical spills, oil, solvents and wet floors. • Make sure the air hose is free of obstructions or snags.
9 SAFETY GUIDELINES ELECTRICAL SAFETY Grounding instructions: In the event of a malfunction or breakdown, grounding provides the path of least resistance for electrical 2 current in order to reduce the risk of electric shock. This tool is equipped with an electric cord that has a grounding wire and a grounding plug (1).

11 IMPORTANT INFORMATION General use This Mastercraft Maximum® 5 U.S. Gallons (18.9 L) Air Compressor is designed to provide compressed air to power air tools. This compressor is provided with an ON/OFF switch, an air tank and a motor with automatic reset thermal overload protector. Air compressor components Air filter The filter is attached to the compressor cylinder head for removing impurities from the air intake of the compressor.
12 This valve automatically gets activated if the compressor does not shut down automatically due to high pressure in the air tank. To operate manually, pull the relief valve ring to relieve air pressure in the tank. Tank pressure gauge The gauge indicates the pressure level of stored air in the air tank. It cannot be adjusted manually. Thermal overload protector This protector will automatically turn OFF the compressor if the temperature of the electric motor exceeds a predetermined limit.
13 ASSEMBLY INSTRUCTIONS Before assembly • Unpack the carton and take out the air compressor. Make sure all parts are present. Inspect the unit for damage. • If any part is missing or damaged, do not attempt to assemble the product. Contact customer service for replacement parts. • Complete a damage claim for replacement parts immediately as there is time limitation.
14 WARNING! Potential hazard that could result in serious injury or loss of life. 1. • Do not touch the compressor while operating, as the motor will be very hot. Allow the compressor to cool before handling or servicing it to avoid skin burns or other injuries. • Do not move or attempt to service the compressor when the air tank is under pressure. • Never use air hose or power cord to pull or move the compressor. If required, use the handle to move it.
15 Potential hazard that may result in moderate injury or damage to equipment. • 3. Wear safety glasses when opening the drain valves, as the air and moisture released from the tank can propel debris that may cause eye injury. Turn the pressure regulator knob (1) counter-clockwise to reduce the pressure at the air line outlet (fig D).
16 WARNING! Potential hazard that could result in serious injury or loss of life. • Check the manufacturer's maximum pressure rating for air tools and accessories. The outlet pressure must never exceed the maximum pressure rating of the air tool. • Do not use any storage cover to cover the compressor during operation. • Never leave the compressor unattended. Failure to comply will result in fire or serious personal injury. 1. Make sure the drain valves are closed. 2.
17 OPERATING INSTRUCTIONS Shut down procedure 1. Turn the ON/OFF switch (1) to the OFF position. Turn OFF the power supply and unplug the power cord (2) from the electrical outlet (fig J). fig J 1 125 150 175 10 200 15 100 75 5 18 225 50 25 0 250 0 125 150 175 10 100 75 5 15 200 0 225 20 250 50 0 25 0 2 MC-589308-12 2. Reduce the pressure in the tank through the air hose. Pulling the safety valve ring (1) will also reduce the pressure in the tank (fig K).
18 General maintenance WARNING! Potential hazard that could result in serious injury or loss of life. • Always shut OFF the compressor, remove the power plug from the electrical outlet, and release all pressure from the air system, before attempting to install, service, relocate, or perform any maintenance in the compressor. • Do not use a damaged tool. If abnormal noise or vibration occurs, rectify the problem before use. • Have the compressor repaired by an authorized service person.
19 MAINTENANCE Checking the safety relief valve 1. Turn ON the power supply to the compressor and allow the motor to run until cut-off pressure is reached. 2. Pull the relief valve ring to check whether it is operating properly and to clear possible obstructions of the valve. 3. Replace the safety relief valve if it does not release pressure when pulling the ring. CAUTION! Potential hazard that may result in moderate injury or damage to equipment.
20 Check that all connections are tight. Small leaks in the tank, hoses, connections or transfer tubes will substantially reduce the compressor performance. Spray a small amount of soapy water around the area of suspected leaks. If bubbles appear, repair, replace or reseal the faulty component. Do not overtighten any connections. Storage Before storing the compressor for a prolonged period, follow the steps below correctly. • Disconnect the power cord and coil it up on the handle.
21 TROUBLESHOOTING Troubleshooting WARNING! Potential hazard that could result in serious injury or loss of life. • • PROBLEM Air pressure is low or compressor does not stop. Always shut OFF the compressor, remove the power plug from the electrical outlet, and release all pressure from the air system, before attempting to install, service, relocate or perform any maintenance in the compressor. Allow the compressor to cool after extended use to avoid skin burns. POSSIBLE CAUSES SOLUTIONS 1.
PROBLEM The motor will not run or start. The compressor overheats. POSSIBLE CAUSES SOLUTIONS 1. The power cord is not plugged in. 1. Plug the power cord into a grounded outlet. 2. The ON/OFF switch is in the OFF position. 2. Set the ON/OFF switch to the ON position. 3. The motor’s thermal overload protector has tripped. 3. Turn the air compressor OFF, unplug the power cord and wait until the motor has cooled down.
