ADD
GASOLINE
Fill fuel tank.
Use fresh, clean, regular unleaded
gasoline with a minimum of 87 octane_ (Use of leaded
gasoline wifl increase carbon and lead oxide deposits
and reduce valve life). Do not mix oil with gasoline,
Purchase fuel in quantities that can be used within 30
days to assure fuel freshness.
IMPORTANT:
WHEN OPERATtNG IN TEMPERATURES
BELOW 32°F(0°C), USE FRESH, CLEAN WINTER GRADE
GASOLINE TO HELP INSURE GOOD COLD WEATHER
STARTING
WARNING:
Experience
indicates that alcohol blended
fuels (called gasohol or using 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 fue! system should be emptied before stor-
age of 30 days or longer.
Drain the gas tank, start the
engine and let it run until the fuel lines and carburetor are
empty. Use fresh fuel next season
See Storage Instruc-
tions for additional
information
Never use engine or
carburetor cleaner products in the fuel tank or permanent
damage may occur.
