Air delivery (SCFM*) @ 40 PSI 6.2 DANGER! Potential hazard that will result in serious injury or loss of life. Air delivery (SCFM*) @ 90 PSI 5.
5 6 RISK OF PERSONAL INJURY. Never spray compressed air or material at self or others. 5. RISK OF BURSTING. Check the maximum pressure rating in the manual or identification 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. 6. RISK OF BURSTING. Do not adjust the pressure switch or safety valve for any reason.
7 8 Air compressor pump (B) A. Electric motor: The motor is used to power the pump. It is equipped with at thermal overload protector. If the motor overheats for any reason, the thermal overload protector will shut it down in order to prevent the motor from being damaged. 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.
KEY PARTS LIST J. Before you start AIR TANK: The tank is where the compressed air is stored. K. POWER CORD: This compressor should be used on a nominal 120 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. Do not use an adapter with this compressor. 10 This Mastercraft® Air Compressor is ideal for a wide-range of applications from, fastening to greasing and engine cleaning.
Assembly INTENDED USE Tool Compatibility Chart Operates Tool Continuously Air Tool 12 Operates Tool Intermittently Not Recommended 1. Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged, contact the retailer immediately. THE CARTON SHOULD CONTAIN: • Air compressor • O wner’s manual • Air 2. 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. 3.
14 Breaking-in the pump 4. Air filter assembly • Screw the air filter onto the pump. 1. Set the pressure switch (C) to the OFF position. OFF Air filter 5. Connect air hose to compressor 2. Open the tank drain valve (I) 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. NOTE: ¼" (6.4 mm) NPT air hose is required for connecting to the air compressor.
OPERATING INSTRUCTIONS 4. Before each start-up Plug in the power cord (K). CAUTION! Use a dedicated circuit. For best performance and reliable starting, the air compressor should be plugged into a dedicated circuit, as close as possible to the fuse box or circuit breaker. 1. 2. 3. NOTE: A circuit breaker is recommended. If the air compressor is connected to a circuit protected by a fuse, use dual element time delay fuses (type “T” only). of bursting.
17 1. 2. 3. ITEM Set the pressure switch (C) to the OFF position. Unplug the power cord (K). Reduce the pressure in the tank through the outlet hose. Pulling the safety valve ring (D) and keeping it open will also reduce the pressure in the tank. Drain the tank DESCRIPTION / REASON Through normal operation of your air compressor, condensation 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.
20 MAINTENANCE To check safety valve PROBLEM WARNING! Risk of bursting. If the safety valve does not work properly, overpressurization may occur, causing air tank rupture or an explosion. • Before starting compressor, pull the ring on the safety valve (D) to make sure that the safety valve operates freely. If the valve is stuck or does not operate smoothly, contact a trained service technician. To drain tank NOTE: Allow unit to cool before draining tank. Drain valve (I) becomes hot during operation.
22 PROBLEM POSSIBLE CAUSES SOLUTIONS The regulator does not regulate the pressure. The regulator or its internal parts are dirty or damaged. Replace the regulator. There is a leak at one of the fittings. The pressure is low or there is not enough air. The tank drain valve is open. The air intake is restricted. Prolonged excessive use of air. There is a hole in the air hose. The tank leaks. The valve is leaking.
