o For cold weather
operation
you should
change
oil for easier starting
((See the
oil viscosity
chart in the Maintenance
section of this manual).
• To change engine oil, see the Mainte-
nance section
in this manual
ADD GASOLINE
o Fill fuel tank to bottom of tank filler neck_
De not overfill
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). Do not mix oil
with gasoline.
Purchase
fuel in quanti-
ties that can be used within 30 days to
assure fuel freshness.
,_CAUTION:
Wipe off any spilled oil or
fuel. Do not store, spill or use gasoline
near an open flame.
IMPORTANT;
When operating
in tempera-
tures below 32°F(0°C),
use fresh, clean
winter grade gasoline
to help insure good
cold weather
starting.
CAUTION:
Alcohol
blended
fuels (called
gasohol or using ethanol
or methanol)
can
attract moisture
which leads to separa-
tion 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 storage of 30
days or Ionger. 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
Instructions
for
additional
information.
Never use engine or carburetor
cleaner
products
in the fuel tank or permanent
damage
may occur.
