This Parts Listing has been compiled for your benefit. You can be assured your Gasoline Air Compressor was constructed and designed with quality and performance in mind. Each component has been rigorously tested to insure the highest level of acceptance. The contents of this Parts Listing are based on the latest product information available at the time of publication. The manufacturer reserves the right to make changes in price, color, materials, equipment, specifications or models at any time without notice. WARNING THIS IS A PROFESSIONAL GASOLINE AIR COMPRESSOR. CAUTION SHOULD BE OBSERVED WHEN USING OR REPAIRING THIS UNIT! READ AND FOLLOW THE SAFETY WARNINGS LISTED BELOW BEFORE ATTEMPTING ANY REPAIRS ON THIS GASOLINE AIR COMPRESSOR! SAFETY WARNINGS 1. NEVER alter or modify the equipment. Be sure any accessory items and system components being used will withstand the pressure developed Serious injury may occur from an air compressor malfunction or exploding accessories if incorrect system components, attachments or accessories are used. NEVER exceed manufactures maximum allowable pressure rating of attachments. Use only genuine manufacturer parts for repair of your air compressor. Failure to do so can cause hazardous operating conditions and will VOID warranty. 2. NEVER make adjustments on machinery while the unit is connected to the engine without first removing the ignition cable from the spark plug. Turning over the machinery by hand during adjustment or cleaning might start the engine and machinery with it, causing serious injury to the operator. 3. Know how to stop and bleed pressures quickly. Be thoroughly familiar with controls. Do not operate without protective covers/ guards. 4. Before servicing the unit, turn unit off, relieve the pressure and allow the unit to cool down. Service in a clean, dry, flat area. Block the wheels to prevent the unit from moving. Be especially careful to properly dispose of any flammable materials. 5. After testing the machine, DO NOT leave the pressurized unit unattended. Shut off the unit and release pressure before leaving.

GENERAL THEORY OF OPERATION 1. The ENGINE (1) supplies power to the air compressor. a. The ENGINE (1) is lubricated by oil. The oil level should be checked before each use by removing the ENGINE OIL DIPSTICK (2). b. The ENGINE (1) runs on gasoline. The FUEL TANK (3) level should be checked before each use. c. The ENGINE ON/OFF SWITCH (4) and STARTER ROPE (5) are used to start the engine. d. Refer to engine owner s manual for appropriate starting procedures and requirements of the ENGINE (1). 2. The COMPRESSOR PUMP (6) is lubricated by oil. The oil level should be checked before each use by viewing the COMPRESSOR PUMP OIL SIGHTGLASS (7). If the oil level is low, add SAE-30W non-detergent oil to the COMPRESSOR PUMP OIL FILL PORT (8). 3. When the unit is operating, the V-BELT (9) turns the COMPRESSOR PUMP FLYWHEEL (10) which rotates the crankshaft and moves the pistons. 4 As the FIRST STAGE PISTON (11) moves down, air is drawn in through the INLET AIR FILTER (12). Then through the FIRST STAGE INLET REED VALVES (13) and into the first stage piston chamber. At the same time, the FIRST STAGE OUTLET REED VALVES (14) is closed. This allows air to fill the first stage piston chamber. 5. As the FIRST STAGE PISTON (11) moves upward, the FIRST STAGE INLET REED VALVE (13) closes. The FIRST STAGE OUTLET REED VALVE (14) opens allowing the compressed air to flow into the INTERCOOLER (15) and into the second stage. 6. As the SECOND STAGE PISTON (16) moves down, the first stage compressed air is drawn in the through the SECOND STAGE INLET REED VALVES (17) and into the second stage piston chamber. At the same time, the SECOND STAGE OUTLET REED VALVES (18) is closed. 7. As the SECOND STAGE PISTON (16) moves upward, the SECOND STAGE INLET REED VALVES (17) closes. The SECOND STAGE OUTLET REED VALVES (18) opens allowing the compressed air to flow into the AFTERCOOLER (19) and DISCHARGE LINE (20). 8. The compressed air then enters the PILOT CONTROL VALVE (21) which has an TOGGLE KNOB (22) with two positions. a. Easy Start Position: When the TOGGLE KNOB (22) is in the open position (vertical) air moves out the PILOT VALVE MUFFLER (23) allowing the ENGINE (1) to start under no-load conditions. b. Constant Run Position: When the TOGGLE KNOB (22) is in the closed position (horizontal) the compressed air opens the CHECK VALVE (24) and moves into the AIR TANK (25). When the pressure in the AIR TANK (25) reaches the maximum pressure setting of the PILOT CONTROL VALVE (21), the excess air exits the PILOT VALVE MUFFLER (23) and the CHECK VALVE (24) will close. At the same time the THROTTLE CONTROL (26) allows the ENGINE (1) to idle down. 9. The SAFETY RELIEF VALVE (27) protects the system from any overpressure conditions. 10. The TANK PRESSURE GAUGE (28) indicates tank pressure. The AIR PRESSURE REGULATOR (29) can be adjusted to the desired operating pressure which is indicated on the OUTLET PRESSURE GAUGE (30). The air exits through the OUTLET FITTING (31). 11. The ENGINE ON/OFF SWITCH (4) stops the ENGINE (1) when moved to the OFF position. 12. When the ENGINE (1) is off, compressed air should be released from the AIR TANK (25) by opening the attached air tool or by pulling on the SAFETY RELIEF VALVE (27). When the TANK PRESSURE GAUGE (28) registers less than 10 PSI, drain the condensation from the AIR TANK (25) by opening the TANK DRAIN (32). 5
