Immediately prepare your lawn mower for
storage at the end of the season or if the unit
will not be used for 30 days or more.
LAWN MOWER
When lawn mower is to be stored for a period
of time, clean it thoroughly, remove all dirt,
grease, leaves, etc. Store in a clean, dry area.
• Clean entire lawn mower (See "CLEANING"
in the Maintenance
section of this manual).
• Lubricate as shown in the Maintenance
section of this manual.
• Be sure that all nuts, bolts, screws, and pins
are securely fastened.
Inspect
moving
parts for damage, breakage and wear.
Replace if necessary.
• Touch up all rusted or chipped paint
surfaces; sand lightly before painting.
HANDLE
• You can fold your lawn mower handle for
storage.

the upper handle and allow handle to fold
down to the roar.

FUELSYSTEM
IMPORTANT:
It is important to prevent gum
deposits from forming in essential fuel system
parts such as carburetor, fuel tilter, fuel hose,
or tank during storage. Also, 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.
• Drain the fuel tank.
• Start the engine and let 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
a]temative 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 drain the gas
tank and carburetor if using fuel stabilizer.
ENGINEOIL
Drain oil (with engine warm) and replacewith
clean engine oil. (See "ENGINE"
in the
Maintenance
section of this manual).
CYLINDER
• Remove spark plug.
• Pour one ounce (29 ml) of oil through spark
plug hole into cylinder.
• Pull starter handle slowly a few times to
distribute oil.

cover it to give protection from dust and dirt.
Cover your unit with a suitable protective
