Area
The tiller tines can throw rocks and other objects with enough force to cause injury. Before tilling, carefully
inspect the area and remove all large debris.
Keep Shields
in Place
Guards and shields are designed to protect you from being hit by thrown objects. They also help protect
you from hot engine parts and moving components.
For your safety and the safety of others, keep all
guards and shields in place when operating the tiller.
Refuel

with

Care

Gasoline is extremely flammable and gasoline vapor can explode. Refuel only outdoors, in a
well-ventilated
area, with the engine off. Never smoke near gasoline, and keep other flames and sparks
away. Always store gasoline in an approved container.
Wear Protective
Clothing
Wearing protective clothing will reduce your risk of injury. Long pants and eye protection reduce the risk of
injuries from thrown objects. Sturdy shoes with aggressive soles will help protect your feet and give you
better traction on slopes or uneven ground. Clothing worn by the operator should be close-fitting.
Loose
clothing should not be permitted because it may get caught in moving parts. Tie up or restrain long hair.

Pulling the throttle lever towards the grip increases
the engine speed which causes the tines to turn.
Releasing the throttle lever reduces engine speed
and stops the tiller tines from turning.
The tiller will have the greatest tilling force at
maximum engine speed. At idle, the tilling tines
should stop rotating.

The choke lever opens and closes the choke valve
in the carburetor.
The CLOSED position enriches the fuel mixture for

TRANSPORTING/STORAGE
Fuem
Gasoline will oxidize and deteriorate in storage.
Old gasoline will cause hard starting, and it leaves
gum deposits that restrict the fuel system. If the
gasoline in your filler deteriorates during storage,
you may need to have the carburetor and other
fuel system components,
serviced or replaced.
The length of time that gasoline can be left in your
fuel tank and carburetor wkhout causing functional
problems will vary with such factors as gasoline
blend, storage temperatures,
and whether the fuel
tank is partially or completely filled. The air in a
partially filled fuel tank promotes fuel deterioration.
Very warm storage temperatures
accelerate fuel
deterioration.
Fuel deterioration problems may
occur within a few months, or even less if the
gasoline

was not fresh when you filled the fuel tank.

You can extend fuel storage life by adding a
gasoline stabilizer that is formulated for that
purpose, or you can avoid fuel deterioration
problems by draining the fuel tank and carburetor.
When adding a fuel stabilizer, fill the fuel tank with
fresh gasoline. If only partially filled, air in the tank
will promote fuel deterioration
during storage, tf
you keep a container of gasoline for refueling, be
sure that it contains only fresh gasoline. Add fuel
stabilizer following the manufacturer's
instructions.

Remove the spark plug (see page 22). Pour a
1/4 tablespoon (1 - 3 cc) of clean engine oil into the
cylinder. Pull the starter rope several times to
distribute the oil in the cylinder. Reinstall the spark
plug. Pull the starter rope slowly until resistance is
felt then return the starter grip gently. This doses
the valves so moisture cannot enter.

PRECAUTIONS

if your tiller will be stored with gasoline in the fuel
tank and carburetor, it is important to reduce the
hazard of gasoline vapor ignition. Select a
well-ventilated
storage area away from any
appliance that operates with a flame, such as a
furnace, water heater, or clothes dryer. Also avoid
any area with a spark-producing
electric motor, or
where power tools are operated.
if possible, avoid storage areas with high humidity,
because that promotes rust and corrosion.

REMOVAL

FROM STORAGE

Check your tiller as described in the BEFORE
OPERA T/ON chapter of this manual (see page 10).
if the fuel was drained during storage preparation,
fill the tank with fresh gasoline. If you keep a
container of gasoline for refueling, be sure that it
contains only fresh gasoline. Gasoline oxidizes and
deteriorates over time, causing hard starting.
if the cylinder was coated with oil during storage
preparation, the engine will smoke briefly at startup.
This is normal.

With the engine and exhaust system cool, cover
the tiller to keep out dust. A hot engine and
exhaust system can ignite or melt some materials.
Do not use sheet plastic as a dust cover. A
nonporous cover will trap moisture, promoting rust
and corrosion.

OXYGENATED

& CONSUMER

iNFORMATiON

FUELS

Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are
collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the USA and
Canada use oxygenated fuels to help reduce emissions. If you use an oxygenated fuel, be sure it is
unleaded and meets the minimum octane rating requirement.
Before using an oxygenated fuel, try to
confirm the fuel's contents. Some states!provinces
require this information to be posted on the pump.
The following
ETHANOL

are the EPA approved
........

MTBE

percentages

of oxygenates:

(ethyl or grain alcohol) 10% by volume
You may use gasoline containing up to 10% ethanol by volume.
ethanol may be marketed under the name "GasohoU'

Gasoline

containing

(Methyl Tertiary Butyl Ether) 15% by volume
You may use gasoline containing up to 15% MTBE by volume.

METHANOL

......

(methyl or wood alcohol) 5% by volume
You may use gasoline containing up to 5% methanol by volume, as long as it also
contains cosoJvents and corrosion inhibkors to protect the fuel system. Gasoline
containing more than 5% methanol by volume may cause starting and/or performance
problems. Jt may also damage metal, rubber, and plastic parts of your fuel system.

If you notice any undesirable operating symptoms, try another service station, or switch to another brand of
gasoline. Fuel system damage or performance problems resulting from the use of an oxygenated fuel
containing more than the percentages of oxygenates mentioned above are not covered under warranty.

CARBURETOR

MODiFiCATiONS

FOR HiGH ALTITUDE

OPERATION

At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and
fuel consumption
will increase. A very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which this engine was certified, for extended periods of
time, may increase emissions.
High altitude performance
can be improved by specific modifications
to the carburetor. If you always
operate your tiller at altitudes above 5,000 feet (1,500 meters), have your servicing dealer perform this
carburetor modification.
This engine, when operated at high altitude, with carburetor modifications for high
altitude use, will meet each emission standard throughout
its useful life.
Even with carburetor modification, engine horsepower will decrease about 3.5% for each 1,000-foot
(300-meter) increase in altitude. The effect of altitude on horsepower will be greater than this if no
carburetor modification
is made.
i NOTICE

When the carburetor has been modified for high altitude operation, the air-fuel mixture will be too lean for
low altitude use. Operation at altitudes below 5,000 feet (1,500 meters) with a modified carburetor may
cause the engine to overheat and result in serious engine damage. For use at low altitudes, have },our
servicing dealer retum the carburetor to original factor}, specifications.

done, These original-design replacement parts are manufactured to the same standards as the original parts, so you
can be confident of their performance, The use of replacement parts that are not of the original design and quality may
impair the effectiveness of your emission control system,
A manufacturer of an aftermarket part assumes the responsibility that the part wiii not adversely affect emission
performance, The manufacturer or rebuilder of the part must certify that use of the part wiii not result in a failure of the
engine to comply with emission regulations,

Maintenance
Follow the maintenance schedule on page 18, Remember that this schedule is based on the assumption that your
machine wiii be used for its designed purpose, Sustained high-load or high-temperature operation, or use in unusually
