OPERA TION Operator Controls The unloader valve for the operation of the gasoline compressor outfit is located between the compressor pump and gasoline engine. The air discharge valve can be located on the end of the air tank. The safety valve and pressure gauge are attached to the tank below the unloader .
P AGE 12 Over-pressurization of the air tank may cause tank rupture or explosion. The air tank is protected from over- pressurization by a safety valve. Do not eliminate, make adjustments or substitutions to this device. Occasion- ally pull the ring on the safety valve to make sure it operates freely .
P AGE 13 4. Check the engine fuel tank level. Add fuel if necessary . Before starting the compressor outfit, check the following: 5. Close the air discharge valve. 6. Set the toggle lever of the unloader valve in the vertical position to relieve compressor head pressure.
c. Check for excessive vibration and noise. Correct any defects found. d. Check for oil leaks. Correct any leaks found. SHUT DOWN PROCEDURES T o stop the engine in an emergency , turn the engine ON/OFF lever or key switch to the OFF position. Un- der normal conditions, use the following procedures.
P AGE 15 WEEKL Y 1. Clean and inspect the compressor air intake filter; replace if necessary . 2. Inspect condition of drive belt; replace if necessary . 3. Clean outside parts of the compressor as well as the engine in order to maintain efficient cooling.
CHECKING AND CHANGING AIR INT AKE FIL TER NOTE Keep the air filter clean at all times. Do not operate compressor outfit when the filters are removed. The condition of the air intake filter should be checked once a week. A dirty air intake filter will not allow the compressor to operate at full capacity and will increase oil usage.
P AGE 17 Figure 8. Checking Belt T ension On compressors equipped with standard V -belts, each belt should deflect 1/4” at the midway point between the engine pulley and flywheel when a downward force of 4 pounds, or equivalent finger pressure, is applied at the midway point.
6. Reinstall the drive belt. Make sure the belt is centered on the engine pulley and flywheel. 7. Slide the engine back into its original position a n d adjust the belt tension, Figure 8.
P AGE 19 6. Reinstall the check valve. DO NOT OVER- TIGHTEN . SER VICING INT AKE AND EXHAUST V AL VES The intake and exhaust valves as well as the valve plates and cylinder head will, over a period of time accumulate residue of carbon-like material on their surfaces.
P AGE 20 TROUBLESHOOTING GUIDE Performing service checks or repairs may expose moving parts, or compressed air sources. Personal injuries may occur . Prior to attempting any service check or repairs, remove the spark plug wire and bleed off all air pressure.
CORRECTION Clean. Be sure outfit is adequately protected from the elements so as to prevent water seeping into system. Adjust. See engine manufacturer's instructions included with engine. Use only fuel recommended by engine manufacturer . See manufacturer's instructions.
PROBLEM Air leaks (cont) Low Discharge Pressure Knocking CORRECTION Operate safety valve manually by pulling on ring. If valve still leaks, it should be replaced. A defective check valve results in a constant air leak, back through the unloader valve when there is pressure in the air tank and the compressor is not running.
TROUBLESHOOTING CHART (Continued) PROBLEM Knocking (cont’d) Excessive Oil Consumption Compressor Over heating P AGE 23 CORRECTION Make sure flywheel is tight by tight- ening screw . T orque screw to 20 +5 -0 foot-pounds. Tighten belt. Replace. Reduce air consumption or add additional air compressor to take up load.
TROUBLESHOOTING CHART (Continued) P AGE 24 CAUSE Restricted air intake. Improper level and/or grade of oil used. Damaged valves (intake and/or exhaust). Loose belt. Pulley misalignment. Loose pulley . Compressor valves leaking, sticking or carboned up.
