AIR FILTER MAINTENANCE ENGINE OIL RECOMMENDATIONS NOTICE Engine oil is a major factor affecting engine performance and service life. NEVER use non-detergent or 2-stroke engine oils. • Use engine oils specified below. It is very important to maintain proper level of engine oil to keep engine in good running condition. • Check engine oil level prior to each use. Refill engine oil if oil level is too low. Use 4-stroke oil, or equivalent high detergent, premium quality motor oil certified to meet or exceed U.S. automobile manufacturer's requirements for API Performance Class SL, SJ, or better. SAE 10W-30 is recommended for general temperature use. Refer to Figure 7-1 for information on other viscosities that may be used. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range. SAE 30, 10W-30 Synthetic 5W-30 5W-30 FIGURE 7-1: Recommended Oil Viscosity NOTE: Dispose of used motor oil according to guidelines established by your local or state government. 7.2 AIR FILTER MAINTENANCE NOTICE A dirty air filter will restrict air flow to carburetor, which may cause poor engine performance or damage. NEVER run the generator without the air cleaner assembly properly attached. Clean air filter every 50 hours of generator operation. If operating generator in extremely dusty areas, clean air filter more frequently. WARNING Gasoline and flammable solvents can cause fire or explosion. NEVER use gasoline or flammable solvent to clean air filter element. • Use only household soap and water to clean air filter element. To clean air filter, you will need: ‰ Household soap and water ‰ Clean, dry cloth ‰ Clean engine oil 1. Stop engine if it is running. 2. Remove air cleaner cover. For Model Numbers Ending in "L": • Unlock the latches at the top and bottom of the air cleaner cover. Low Oil Protection The generator engine is protected from low lubrication failure by an oil shutdown switch. This switch prevents the operation of the ignition system until sufficient oil is added to the crankcase for proper engine lubrication. When engine shuts down due to low oil level: 1. The engine control switch will remain in the RUN posi- tion. 2. The engine will not start until the required amount of engine oil is added. WARNING ALWAYS stop engine before removing oil fill dipstick. Crankcase pressure can cause hot engine oil to spray out of engine fill hole. Hot engine oil can cause severe burns.
