To ensure that the engine runs smoothly use only FRESH, UNLEADED GAS WITH AN

producing car boll deposit and will prolong the engine's service life. Never apply used or polluted
gasoline or a mixture of gasoline with engine oil. Make sure the fuel is free of dirt and water.
Gasoline Containing Alcohol
If you decide to use a gasoline containing alcohol (fuel blend), be sure its octane rating is at least
as high as that recommended by the company. There are two types of"gasohol". One contains
ethanol, and the other contains methanol. Neither gasoline containing more than 10% ethanol nor
5% methanol is allowed to be used. If methanol content in the fuel blend exceeds 5%, it may bring
