ADD GASOLINE
= Fill fuel tank. Use fresh, clean, regular unleaded
gasoline with a minimum of 87 octane.. (Use of leaded
gasoline will increase carbon and lead oxide deposits
and reduce valve life)o Do not mix oil with gasoline.
Purchase fuel in quantities that can be used within 30
days to assure fuel freshness.
IMPORTANT; WHEN OPERATING 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 fuel 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.
I_ CAUTION: Fill to bottom of gas tank
filler neck. Do not overfill. Wipe offany
spilled oil or fuel Do not store, spill or
use gasoline near an open flame.
