DO NOT USE a defective screen. If screen is not damaged, clean it with commercial solvent. * Replace the screen and the retaining bracket. Section 3 — Maintenance Commercial-Industrial-Residential Portable Generator System MAINTENANCE §^=0 Figure 21 - Spark Arrestor the allen wrench and tighten the rocker arm jam nut. Tighten the jam nut to 174 in/lbs. torque. After tightening the jam nut, recheck valve clearance to make sure it did not change. Figure 22 - Valve Clearance Adjustment MUFFLER OUTLET 3.6 ADJUSTING VALVE CLEARANCE After the first 50 hours of ^ratron you should adjust * Install new valve cover gasket. * Make sure the engine is at room temperature. * Make sure that the spark plug wire is removed from the spark plug and out of the way. * Remove the four screws attaching the valve cover with a #2 or #3 phillips screwdriver. * Make sure the piston is at Top Dead Center (TDC) of its compression stroke (both valves closed). To get the piston at TDC, remove the intake screen at the front of the engine to gain access to the flywheel nut. Use a large socket and socket wrench to rotate the nut and hence the engine. While watching the piston through the spark plug hole. The piston should move up and down. The piston is at TDC when it is up as high as it can go. * Loosen the rocker jam nut. Use an 10mm allen wrench to turn the pivot ball stud while checking clearance between the rocker arm and the valve stem with a feeler gauge. Correct clearance is 0.002-0.004 inch (0.05-0.1 mm). NOTE: You must hold the rocker arm jam nut in place as you turn the pivot ball stud. When valve clearance is correct, hold the pivot ball stud in place with the valve clearance in the engine. * Re-attach the valve cover. Important: If you feel uncomfortable about doing this procedure or you don't have the proper tools, please take your generator in to the nearest service center to have the valve clearance adjusted. This is a very important step to insure longest life for your engine. NOTE: Start all four screws before tightening or you will not be able to get all the screws in place. Make sure the valve cover gasket is in place. To adjust valve clearance: Re-attach the spark plug wire to the spark plug. Repeat the process for the other cylinder. 17 Section 3 — Maintenance MAINTENANCE Commercial-Industrial-Residential Portable Generator System —o STORAGE 3.7 GENERAL The generator should be started at least once every seven days and be allowed to run at least 30 minutes. If this cannot be done and you must store the unit for more than 30 days, use the following information as a guide to prepare it for storage. AAdANGER! NEVER store engine with fuel in tank indoors or in enclosed, poorly ventilated areas where fumes may reach an open flame, spark or pilot light as on a furnace, water heater, clothes dryer or other gas appliance. 3.8 LONG TERM STORAGE It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel hose or tank during storage. Also, experience indicates that alcohol-blended fuels (called gasohol, ethanol or methanol) can attract moisture, which leads to separation and formation of acids during storage. Acidic gas can damage the fuel system of an engine while in storage. To avoid engine problems, the fuel system should be emptied before storage of 30 days or longer, as follows: * Remove all gasoline from the fuel tank. AAdANGER! Drain fuel into approved container outdoors, away from open flame. Be sure engine is cool. Do not smoke. * Start and run engine until engine stops from lack of fuel. * While engine is still warm, drain oil from crankcase. Refill with recommended grade. * Remove spark plugs and pour about 1/2 ounce (15 ml) of engine oil into the cylinders. Cover spark plug hole with rag. Press the “Start” button and allow engine to crank for 2 seconds. Then press the “Stop” button. AcAUTION! Avoid spray from spark plug holes when cranking engine. * Install and tighten spark plugs. Do not connect spark plug wires. * Clean the generator outer surfaces. Check that cooling air slots and openings on generator are open and unobstructed. * Store the unit in a clean, dry place. 3.9 OTHER STORAGE TIPS: * Do not store gasoline from one season to another. * Replace your gasoline can if your can starts to rust. Rust and/or dirt in your gasoline will cause problems with the carburetor and fuel system. * If possible, store your unit indoors and cover it to give protection from dust and dirt. BE SURE TO EMPTY THE FUEL TANK. * If it is not practical to empty the fuel tank and the unit is to be stored for some time, use a commercially available fuel stabilizer added to the gasoline to increase the life of the gasoline. * Cover your unit with a suitable protective cover that does not retain moisture. AdANGER! NEVER cover your generator while engine and exhaust area are warm. 18 Section 4 — Troubleshooting Commercial-Industria...
