TILLER SAFETY
IMPORTANT SAFETY INFORMATION

Honda tillers are designed to cultivate earth outdoors. Other uses can
result in injury to the operator or damage to the tiller and other
property.

Most accidents can be prevented if you follow all instructions in this

manual and on the tiller. The most common hazards are discussed
below, along with the best way to protect yourself and others.

Operator Responsibility

Know how to stop the tiller quickly in case of emergency.

Understand the use of all tiller controls.

Be very cautious when operating the tiller in REVERSE, especially if

attachments are being used.

Keep a firm hold on the handlebars. They may tend to lift during
clutch engagement.

Be sure the drag bar is in place and properly adjusted.

Be sure that anyone who operates the tiller receives proper

instruction. Do not let children operate the tiller. Keep children and
pets away from the area of operation.

Carbon Monoxide Hazards

Exhaust contains poisonous carbon monoxide, a colorless, odorless

gas. Breathing carbon monoxide can cause loss of consciousness
and may lead to death.

If you run the tiller in a confined or even partially enclosed area, the
air you breathe could contain dangerous amounts of carbon
monoxide. To keep carbon monoxide from building up, provide
adequate ventilation.

5
11/07/26 18:37:37 31V20700_008

TILLER SAFETY
Fire and Burn Hazards

The exhaust system gets hot enough to ignite some materials.

Keep the tiller at least 3 feet (1 meter) away from buildings and
other equipment during operation.

Keep flammable materials away from the tiller.

The muffler becomes very hot during operation and remains hot for
a while after stopping the engine.
Be careful not to touch the muffler while it is hot. Let the engine cool
before storing the tiller indoors.

Refuel With Care

Gasoline is extremely flammable, and gasoline vapor can explode.

Allow the engine to cool if the tiller has been in operation. Refuel only
outdoors in a well-ventilated area with the engine OFF. Do not overfill
the fuel tank. Never smoke near gasoline, and keep other flames and
sparks away. Always store gasoline in an approved container. Make
sure that any spilled fuel has been wiped up before starting the engine.

Avoid Rotating Tines

Rotating tines can cause serious cuts and even amputate body parts.
Keep away from the tine area whenever the engine is running. If you
need to work around the tines to clear an object accumulation or for
any other reason, always shut off the engine. Disconnect the spark
plug cap, and wear heavy gloves when you need to clean the tine area
or handle the tines.

Clear Tilling Area

A tine can throw rocks and other objects with enough force to cause
serious injury. Before tilling, carefully inspect the area and remove all
stones, sticks, bones, nails, pieces of wire, and other loose objects. Be
aware; if children are in the shop area, stop the tiller. Never operate
the tines over gravel.

6
11/07/26 18:37:48 31V20700_009

TILLER SAFETY
Keep Shields in Place

Guards and shields are designed to protect you from being hit by
thrown objects and to keep you from touching hot engine parts and
moving components. For your safety and the safety of others, keep all
shields in place when the engine is running.

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 provide better traction.

Turn Engine Off When Not Operating the Tiller

If you need to leave the tiller for any reason, even just to inspect the
area ahead, always turn the engine off.

Slope Operation

When tilling on slopes, keep the fuel tank less than half full to
minimize fuel spillage.

Till across the slope (at equally spaced intervals) rather than up and
down it.

Be very careful when changing the direction of the tiller on a slope.

Do not use the tiller on a slope of more than 10°. Before starting the
engine, check that the tiller is not damaged and is in good condition.
For your safety and the safety of others, exercise extreme care when
using the tiller on a slope.

Tilling Conditions

Operate the tiller only in daylight or good artificial light. Do not

operate the tiller at night or under poor light conditions.

BEFORE OPERATION
ARE YOU READY TO GET STARTED?

Your safety is your responsibility. A little time spent in preparation will

significantly reduce your risk of injury.

Knowledge

Read and understand this manual. Know what the controls do and
how to operate them.

Familiarize yourself with the tiller and its operation before you begin
using it. Know how to quickly shut off the tiller in case of an
emergency.

IS YOUR TILLER READY TO GO?

For your safety, and to maximize the service life of your equipment, it
is very important to take a few moments before you operate the tiller
to check its condition. Be sure to take care of any problem you find, or
have your servicing dealer correct it, before you operate the tiller.

Improperly maintaining this tiller, or

failing to correct a problem before
operation, could cause a
malfunction in which you could be
seriously injured.

Always perform a pre-operation

inspection before each operation,
and correct any problem.

16
11/07/26 18:39:39 31V20700_019

BEFORE OPERATION
Do not place flammable objects close to the engine.

Before beginning your pre-operation checks, be sure the tiller is on a

level surface and the engine switch is in the OFF position.

Check the Engine

Check the oil level (see page 33 ).

Check the air filter (see page 37 ). A dirty air filter will restrict air flow to
the carburetor, reducing engine and tiller performance.

Check the fuel level (see page 31 ). Starting with a full tank will help to
eliminate or reduce operating interruptions for refueling.

Check the Tiller

Check the transmission oil (see page 36 ).

11/07/26 18:39:44 31V20700_020

OPERATION
SAFE OPERATING PRECAUTIONS

Before operating the tiller for the first time, please review both the
TILLER SAFETY chapter and the chapter titled BEFORE OPERATION.

For your safety, avoid starting or operating the tiller in an enclosed

area such as a garage. Your tiller’s exhaust contains poisonous carbon
monoxide gas that can collect rapidly in an enclosed area and cause
illness or death.

Carbon monoxide gas is toxic.

Breathing it can cause
unconsciousness and even kill you.

Avoid any enclosed areas or

activities that expose you to carbon
monoxide.

OPERATION
HANDLING TIPS

Adjust the handlebar height to a comfortable position (waist height

for normal tilling).

The drag bar should always be used when tilling. It enables you to
compensate for the hardness of the soil. The ideal height of the drag
bar will depend on the type of soil being tilled and soil conditions at
the time of tilling. In general, however, the drag bar should be
adjusted so that the tiller is tilted slightly backward.

If the machine jerks forward while tilling, press down on the

handlebars. This will cause the drag bar to dig more deeply into the
soil.

If tines dig in but the machine will not move forward, move the
handlebars from side to side.

Stop the tines before crossing gravel drives, walks, or roads. Stay
alert for hidden hazards or traffic.

Stop the engine immediately if the tiller vibrates abnormally. Check

the tiller for damage or loose parts, and repair or replace them
before using the tiller again. Vibration is usually a sign of trouble.

THE IMPORTANCE OF MAINTENANCE

Good maintenance is essential for safe, economical, and trouble-free

operation. It will also help reduce air pollution.

To help you properly care for your tiller, the following pages include a
maintenance schedule, routine inspection procedures, and simple
maintenance procedures using basic hand tools. Other service tasks
that are more difficult or require special tools are best handled by
professionals and are normally performed by a Honda technician or
other qualified mechanic.

The maintenance schedule applies to normal operating conditions. If

you operate your tiller under unusual conditions, such as sustained
high-load or high-temperature operation or use in dusty conditions
consult your servicing dealer for recommendations applicable to your
individual needs and use.

Improper maintenance, or failure to

correct a problem before operation,
can cause a malfunction in which
you can be seriously hurt or killed.

Always follow the inspection and

maintenance recommendations and
schedules in this owner’s manual.

Remember that your servicing dealer knows your tiller best and is fully
equipped to maintain and repair it.

To ensure the best quality and reliability, use only new, Honda
Genuine parts or their equivalents for repair and replacement.

Maintenance, replacement, or repair of the emission control devices

and systems may be performed by any engine repair establishment or
individual, using parts that are ‘‘certified’’ to EPA standards.

SERVICING YOUR TILLER

MAINTENANCE SAFETY

Some of the most important safety precautions follow. However, we

cannot warn you of every conceivable hazard that can arise in
performing maintenance. Only you can decide whether or not you
should perform a given task.

Failure to properly follow

maintenance instructions and
precautions can cause you to be
seriously hurt or killed.

Always follow the procedures and

precautions in the owner’s manual.

Safety precautions

Make sure the engine is off before you begin any maintenance or
repairs. This will eliminate several potential hazards:

Carbon monoxide poisoning from engine exhaust.

Be sure there is adequate ventilation whenever you operate the
engine.

Burns from hot parts.

Let the engine and exhaust system cool before touching.

Injury from moving parts.

Do not run the engine unless instructed to do so.

Read the instructions before you begin, and make sure you have the
tools and skills required.

To reduce the possibility of fire or explosion, be careful when

working around gasoline. Use only a non-flammable solvent, not
gasoline, to clean parts. Keep cigarettes, sparks, and flames away
from all fuel-related parts.

Disconnect the spark plug cap and wear heavy gloves when working
near the belts or tine blades.

STORAGE PREPARATION

Proper storage preparation is essential for keeping your tiller trouble-

free and looking good. The following steps will help to keep rust and
corrosion from impairing your tiller’s function and appearance, and
will make the engine easier to start when you use the tiller again.

Cleaning

1. Wash the tiller, including the underside.

Engine

Wash the engine by hand, and be careful to prevent water from

entering the air cleaner.

Using a garden hose or pressure washing equipment can force

water into the air cleaner. Water in the air cleaner will soak the
filter elements and can enter the carburetor or engine cylinder,
causing damage.
Water contacting a hot engine can cause damage. If the engine
has been running, allow it to cool for at least half an hour before
washing.

Tiller

If using a garden hose or pressure washing equipment to clean the

tiller, be careful to avoid getting water on the belts.

Spraying water on hot tine shaft bearings can cause them to be

damaged from cooling too quickly.

49
11/07/26 18:44:58 31V20700_052

STORAGE
2. After washing the tiller, wipe dry all accessible surfaces.

3. Start the engine outdoors, and let it run until it reaches normal
operating temperature to evaporate any water remaining on the
engine.

4. While the engine is running, operate the clutch lever to expel water
from the pulleys, belts, and other moving items.

5. Stop the engine and allow it to cool.

6. After the tiller is clean and dry, touch up any damaged paint and
coat other areas with a light film oil. Lubricate the throttle cable core
with a silicone spray lubricant.

Fuel

Depending on the region where you operate your equipment, fuel

formulations may deteriorate and oxidize rapidly. Fuel deterioration
and oxidation can occur in as little as 30 days and may cause damage
to the carburetor and/or fuel system. Please check with your servicing
dealer for local storage recommendations.

Gasoline will oxidize and deteriorate in storage. Old gasoline will

cause hard starting, and it leaves gum deposits that clog the fuel
system. If the gasoline in your tiller 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 without causing functional problems will vary with such
factors as gasoline blend, your 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.

STORAGE
The Distributor’s Limited Warranty does not cover fuel system
damage or engine performance problems resulting from neglected
storage preparation.

A type
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.

Adding a Gasoline Stabilizer to Extend Fuel Storage Life (A type)

When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline.
If only partially filled, air in the tank will promote fuel deterioration
during storage. If you keep a container or gasoline for refueling, be
sure that it contains only fresh gasoline.

1. Add gasoline stabilizer following manufacturer’s instructions.

2. After adding a gasoline stabilizer, run the engine outdoors for 10

minutes to be sure that treated gasoline has replaced the untreated
gasoline in the carburetor.

3. Stop the engine, and turn the fuel valve to the off position.

2. Remove the spark plug (see page 39 ).

3. Pour a teaspoon (5 cc) of clean engine oil into the cylinder.

4. Pull the starter rope several times to distribute the oil in the cylinder.

5. Reinstall the spark plug.

6. Pull the starter grip slowly until resistance is felt and the notch on
the starter pulley aligns with the hole at the top of the recoil starter
cover. This will close the valves so that moisture cannot enter the
engine cylinder. Return the starter rope gently.

STARTER GRIP

Align the notch on the starter pulley with

the hole at the top of recoil starter cover.

11/07/26 18:45:35 31V20700_056

STORAGE
STORAGE 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.

Unless all fuel has been drained from the fuel tank, leave the fuel valve
in the OFF position to reduce the possibility of fuel leakage.

Place the tiller on a level surface. Tilting can cause fuel or oil leakage.

When the engine and exhaust system is 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 around the tiller, promoting rust and corrosion.

REMOVAL FROM STORAGE

Check your tiller as described in the BEFORE OPERATION chapter of

this manual (see page 16 ).

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 may smoke briefly at start-up. This is normal.

54
11/07/26 18:45:42 31V20700_057

TRANSPORTING
BEFORE LOADING

If the engine has been running, allow it to cool for at least 15 minutes
before loading the tiller on the transport vehicle. A hot engine and
exhaust system can burn you and can ignite some materials.

Always turn the ignition switch to the OFF position. Make sure to turn
the fuel valve OFF.

LOADING AND UNLOADING

If a suitable loading ramp is not available, two people should lift the
tiller on and off the transport vehicle while holding the tiller level.

Position the tiller so it sits flat on the bed of the transport vehicle. Tie
the tiller down with rope or straps. Keep the tie-down rope or straps
away from the controls, adjustment levers, cables, and the carburetor.

TECHNICAL INFORMATION
Carburetor Modification 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 car-
buretor modification. This engine, when operated at high altitude with
the 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 ef-
fect of altitude on horsepower will be greater than this if no carburetor
modification is made.

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 your servicing dealer return the
carburetor to original factory specification.

TECHNICAL INFORMATION
Emission Control System Information

Source of Emissions

The combustion process produces carbon monoxide, oxides of

nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of
nitrogen is very important because, under certain conditions, they
react to form photochemical smog when subjected to sunlight. Carbon
monoxide does not react in the same way, but it is toxic.

Honda utilizes appropriate air/fuel ratios and other emissions control

systems to reduce the emissions of carbon monoxide, oxides of
nitrogen, and hydrocarbons.

Additionally, Honda fuel systems utilize components and control

technologies to reduce evaporative emissions.

The U.S., California Clean Air Act, and Environment Canada

EPA, California, and Canadian regulations require all manufacturers to

furnish written instructions describing the operation and maintenance
of emission control systems.

The following instructions and procedures must be followed in order

to keep the emissions from your Honda engine within the emission
standards.

Tampering and Altering

Tampering is a violation of Federal and California law.

Tampering with or altering the emission control system may increase

emissions beyond the legal limit. Among those acts that constitute
tampering are:

Removal or alteration of any part of intake, fuel, or exhaust system.

Altering or defeating the governor linkage or speed-adjusting

mechanism to cause the engine to operate outside its design
parameters.

61
11/07/26 18:46:34 31V20700_064

TECHNICAL INFORMATION
Problems That May Affect Emissions

If you are aware of any of the following symptoms, have your engine
inspected and repaired by your authorized Honda servicing dealer.

Hard starting or stalling after starting

Rough idle

Misfiring or backfiring under load

Afterburning (backfiring)

Black exhaust smoke or high fuel consumption

Replacement Parts

The emission control systems on your new Honda engine were

designed, built, and certified to conform with applicable emission
regulations. We recommend the use of Honda Genuine parts
whenever you have maintenance 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 will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of the part
will not result in a failure of the engine to comply with emission
regulations.

Maintenance

Follow the MAINTENANCE SCHEDULE on page 30 . Remember that

this schedule is based on the assumption that your machine will be
used for its designed purpose. Sustained high-load or high-
temperature operation, or use in unusually wet or dusty conditions,
will require more frequent service.
