BATTERY
• Fully charge
the battery
for storage.
• After
a period
of time
in storage,
battery
may require
recharging.
• To help prevent
corrosion
and power
leak-
age during long periods
of storage,
battery
cables
should
be disconnected
and bat-
tery cleaned
thoroughly
(see "TO CLEAN
BATTERY
AND
TERMINALS"
in the
Maintenance
section
of this manual).
• After cleaning,
leave cables disconnected
and place cables where
they cannot come
in contact
with battery
terminals.
• If battery
is removed
from
tractor
for
storage,
do not store

ENGINE
FUEL SYSTEM
IMPORTANT:
It is important
to prevent
gum deposits
from forming
in essential
fuel
system
parts such as carburetor,
fuel hose,
or tank during storage.
Also, 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.
• Empty the fuel tank by starting
the engine
and letting
it run until the fuel
lines
and
carburetor
are empty.
• Never
use engine
or carburetor
cleaner
products
in the
fuel
tank
or permanent
damage
may occur.
• Use fresh fuel next season.
NOTE:
Fuel
stabilizer
is an acceptable
alternative
in minimizing
the
formation
of
fuel
gum
deposits
during
storage.
Add
stabilizer
to gasoline
in fuel tank or storage
container.
Always
follow the mix ratio found
on stabilizer
container.
Run engine
at least
10 minutes
after adding
stabilizer
to allow
the stabilizer
to reach the carburetor.
Do not
empty
the gas tank and carburetor
if using
fuel stabilizer.
ENGINE
OIL
Drain
oil (with
engine
warm)
and
replace
with clean
engine
oil.

in the

section
of this manual).

OTHER
• Do not store gasoline
from one season
to
another.
Replace your gasoline
can if your can starts
to rust.
Rust and/or
dirt in your gasoline
will cause
problems.
• If possible,
store your tractor
indoors
and
cover itto give protection
from dust and dirt.
• Cover
your tractor
with a suitable
protec-
tive cover that does
not
retain
moisture.

Plastic
cannot
breathe
which allows condensation
to form and will
cause
your tractor
to rust.
IMPORTANT:
Never
cover
tractor
while
engine
and exhaust
areas
are still warm.
