Immediately prepare your tiller for storage at the end of the season or if the unit will not be used for 30 days or more. _i_CAUTION: Never store the tiller with gasoline in the tank inside a building where fumes may reach an open flame or spark. Allow the engine to cool before storing in any enclosure. TILLER 1. Clean entire tiller (See "CLEANING" in the Maintenance section of this manual). 2. Inspect and replace belts, if necessary (See belt replacement instructions in the Service and Adjustments section of this manual). 3. Lubricate as shown in the Maintenance section of this manual. 4. Be sure that all nuts, bolts and screws are securely fastened. Inspect moving parts for damage, breakage and wear. Replace if necessary. 5. Touch up all rusted or chipped paint surfaces; sand lightly before painting. ENGINE FUEL SYSTEM IMPORTANT: It is important to prevent gum deposits from forming in essential fuel system parts such as the carburetor, fuel filter, 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 en- gine 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 carbure- tor. Do not empty the gas tank and carburetor if using fuel stabilizer. ENGINE OIL Drain oil (with engine warm) and replace with clean oil. (See "ENGINE" in the Maintenance section of this manual). CYLINDER 1. Remove spark plug. 2. Pour 1 ounce (29 ml) of oil through spark plug hole into cylinder. 3. Pull starter handle slowly several times to distribute oil. 4. Replace with new spark plug. 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 unit indoors and cover it to give protection from dust and dirt. • Cover your unit with a suitable protective cover that does not retain moisture. Do not use plastic. Plastic cannot breathe which allows condensation to form and will cause your unit to rust. IMPORTANT: Never cover tiller while en- gine and exhaust areas are still warm. 19

Immediately
prepare
your
tiller
for
storage
at the
end
of the
season
or if the
unit
will
not be
used
for
30 days
or more.
_i_CAUTION:
Never
store
the tiller
with
gasoline
in the
tank
inside
a building
where
fumes
may
reach
an open
flame
or spark.
Allow
the
engine
to cool
before
storing
in any
enclosure.
TILLER
1.
Clean
entire
tiller
(See
"CLEANING"
in the
Maintenance
section
of this
manual).
2.
Inspect
and
replace
belts,
if necessary
(See
belt
replacement
instructions
in
the
Service
and
Adjustments
section
of
this
manual).
3.
Lubricate
as
shown
in the
Maintenance
section
of this
manual.
4.
Be sure
that
all nuts,
bolts
and
screws
are
securely
fastened.
Inspect
moving
parts
for
damage,
breakage
and
wear.
Replace
if necessary.
5.
Touch
up all
rusted
or chipped

ENGINE
FUEL
SYSTEM
IMPORTANT:
It is important
to prevent
gum
deposits
from
forming
in essential
fuel
system
parts
such
as the
carburetor,
fuel
filter,
fuel
hose,
or tank
during
stor-
age.
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
en-
gine
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 stor-
age
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
carbure-
tor.
Do
not empty
the
gas
tank
and
carbu-
retor
if using
fuel
stabilizer.
ENGINE
OIL
Drain
oil
(with
engine
warm)
and
replace
with
clean
oil.
(See
"ENGINE"
in the
Maintenance
section
of this
manual).
CYLINDER
1.
Remove
spark
plug.
2.
Pour
1 ounce
(29 ml)
of oil through
spark
plug
hole
into
cylinder.
3.
Pull
starter
handle
slowly
several
times
to
distribute
oil.
4.
Replace
with
new
spark
plug.
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
unit
indoors
and
cover
it to
give
protection
from
dust
and
dirt.
Cover
your
unit
with
a suitable
protec-
tive
cover
that
does
not
retain
moisture.
Do
not
use
plastic.
Plastic
cannot
breathe
which
allows
condensation
to
form
and
will
cause
your
unit to
rust.
IMPORTANT:
Never
cover
tiller
while
en-
gine
and
exhaust
areas
are
still
warm.
