REFUELING This engine is certified to operate on unleaded gasoline with a pump

problems that result from using a fuel with percentages of ethanol or
methanol greater than shown above are not covered by warranty.
If your equipment will be used on an infrequent or intermittent basis,
please refer to the fuel section of the STORAGE chapter (page 7) for
