SERVICE AND ADJUSTMENTS
ENGINE
Maintenance, repair, or replacement of the emission control
devices and systems, which are being done at the cus tom-
ers expense, may be performed by any non-road engine
repair establishment or individual. Warranty repairs must
be performed by an authorized engine manufacturer's
service outlet.
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.
WARNING: Never store the tiller with
gasoline in the tank inside a build ing
where fumes may reach an open flame
or spark. Allow the engine to cool before
storing in any enclosure.
TILLER
• Clean entire tiller (See "CLEANING" in the Maintenance
section of this manual).
• Inspect and replace belts, if nec es sary (See belt re-
place ment in struc tions in the Service and Ad just ments
section of this manual).
• Lubricate as shown in the Maintenance section of this
manual.

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, 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
car bu re tor are empty.
• Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.
NOTE: Fuel stablizer is an acceptable alternative inmini-
mizing 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 stablizer container.
Run engine at least 10 minutes after adding stablizer to
allow the stabilizer to reach the carburetor. Do not drain
the gas tank and carburetor if using fuel stabilizer.
IMPORTANT:
GOVERNOR, WHICH IS FACTORY SET FOR PROPER ENGINE
SPEED. OVERSPEEDING THE ENGINE ABOVE THE FACTORY
HIGH SPEED SETTING CAN BE DANGEROUS. IF YOU THINK
THE ENGINE-GOVERNED HIGH SPEED NEEDS ADJUSTING,
CONTACT YOUR NEAREST AUTHORIZED SERVICE CENTER/
DEPARTMENT, WHICH HAS THE PROPER EQUIPMENT AND
EXPERIENCE TO MAKE ANY NECESSARY ADJUSTMENTS.

STORAGE

ENGINE OIL

Drain oil (with engine warm) and replace with clean oil.
(See "ENGINE" in the Maintenance section of this man ual).
CYLINDER(S)
• Remove spark plug.
• Pour 1 ounce (29 ml) of oil through spark plug hole
into cylinder.
• Pull starter handle slowly several times to distribute
oil.
• 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 pro tec tive cover that
does not retain moisture. Do not use plastic. Plastic
cannot breathe which allows con den sa tion to form
and will cause your unit to rust.
IMPORTANT: NEVER COVER TILLER WHILE ENGINE AND
EXHAUST AREAS ARE STILL WARM.
