GLOSSARY CFM: Cubic feet per minute. SCFM: Standard cubicfeet per minute; a unit of measure of air delivery. PSIG: Pounds per square inch gauge; a unit of measure of pressure. ASME: American Society of Mechanical Engineers; made, tested, inspected and registered to meet the standards of the ASME. Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use your accessory. When the tank pressure drops to a certain low level the motor will restart automatically.

DESCRIPTION OF OPERATION Air Compressor Pump: To compress air, the pistons move up and down in the cylinders. On the downstroke, air is drawn in through the air intake valves. The exhaust valves remain dosed. On the upstroke of the piston, air iscompressed. The intake valves close and compressed air is forced out through the exhaust valves, through the outlet tubes, through the check valve and intothe air tank.

Extension Cords Use extra air hose instead of an extension cord to avoid voltage drop and power loss to the motor, and to prevent overheating. If an extension cord must be used, be sure it is: a 3-wira extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that will accept the plug on the product The portable air compressor is equipped with a cord having a grounding wire with an appropdate grounding plug.

TROUBLESHOOTING GUIDE (Continued) PROBLEM CAUSE CORRECTION Air leak from safety valve. Possible defect in safety valve. Operate safety valve manually by puning on ring. tf valve still leaks, it should be replaced. Knocking Noise Defective check valve. Remove and clean, or replace, Compressor is not supplying enough air to operate accessories. Prolonged excessive use of air.
