To ensure safe operation
Operator responsibility
Read the owner’s manual carefully. Be familiar with the controls
and their proper use of the tiller.
Use the tiller for the purpose it is intended that is, cultivating the soil.
Any other use could be dangerous or damage the equipment,
especially never use it to cultivate soil containing rocks, stones,
wires and any other hard materials.
Never allow children or people unfamiliar with this owner’s manual
to use the tiller. Local regulations may restrict the age of the
operator.
Before each use, visually inspect the tiller including parts for any
wear, damage and looseness. If necessary, replace the damaged
partsasanassembly.
Keep in mind that the owner or user is responsible for accidents or
damage, occurring to other people or their property.
In the event of hire use, be sure that operational explanations are
given in the presence of the user.
Keep your hands and feet away from the tines while the engine is
running.
Allowing anyone to operate this tiller without proper instruction
may result in injury.

To ensure safe operation
Operator responsibility
Stop the engine in the following cases:
−
Whenever you leave the tiller unattended.
−
Before refueling
When stopping the engine, move the throttle lever to the LOW
position, then turn the engine switch OFF. If the fuel valve is
equipped on the tiller, be sure to turn the fuel valve OFF.
Keep all nuts, bolts and screws tight to be sure the tiller is in safe
working condition. Regular maintenance is an essential aid to user’s
safety and retaining a high level of performance.
Never store the tiller with gasoline in the tank inside a building
where fumes may reach an open flame, spark or high temperature
source.
Allow the engine to cool before storing in any enclosure.
To reduce the fire hazard, keep the tiller especially the engine,
muffler, the gasoline storage area as well, free of grass, leaves, or
excessive grease.
Do not leave containers of vegetable matters in or near a building.
If the fuel tank has to be drained, this should be done outdoors, with
a cold engine.
Replace the worn or damaged parts for safety.
Child safety
Keep children indoors and supervised at all times when any outdoor
power equipment is being used nearby. Young children move
quickly and are attracted especially to the tiller and the tilling
activity.
Never assume children will remain where you last saw them. Be
alert and turn the tiller off if children enter the area.
Children should never be allowed to operate the tiller, even under
adult supervision.
−
Thrown object hazard
Objects hit by the rotating tines can be thrown from the tiller with
great force, and may cause serious injury.
Before tilling, clear the tilling area of sticks, large stones, wire, glass,
etc. Till only in daylight.
Always inspect the tiller for damage after striking a foreign object.
Repair or replace any damaged parts before continuous use.
Pieces thrown from worn or damaged tines can cause serious injury.
Always inspect the tines before using the tiller.
5
To ensure safe operation
Fire and burn hazard
Gasoline is extremely flammable, and gasoline vapor can explode.
Use extreme care when handling gasoline. Keep gasoline out of reach
of children.
Add fuel before starting the engine. Never remove the cap of the
fuel tank or add gasoline while the engine is running or when the
engine is hot.
Refuel in a well-ventilated area with the engine stopped.
Refuel outdoors only and do not smoke while refueling or handling
fuel.
Allow the engine to cool before refueling. Fuel vapor or spilled fuel
may ignite.
The engine and exhaust system become very hot during operation
and remain hot for a while after stopping. Contact with hot engine
components can cause burn injuries and can ignite some materials.
Avoid touching a hot engine or exhaust system.
Allow the engine to cool before performing maintenance or storing
the tiller indoors.
Tighten all fuel tanks and container caps securely.
Store fuel in containers specifically designed for this purpose.
If gasoline is spilled, do not attempt to start the engine but move the
tiller away from the area of spillage and avoid creating any source
of ignition until gasoline vapors have dissipated.

6
To ensure safe operation
Carbon monoxide poisoning hazard
Exhaust contains poisonous carbon monoxide, a colorless and
odorless gas. Breathing exhaust can cause loss of consciousness and
may lead to death.
If you run the engine in an area that is confined or even partially
enclosed, the air you breathe could contain a dangerous amount of
exhaust gas. To keep exhaust gas from building up, provide
adequate ventilation.
Replace faulty muffler.
Do not operate the engine in a confined space where dangerous
carbon monoxide fumes can collect.
Operation on slope
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°.
The maximum safe grade angle shown is for reference purpose only
and should be determined according to the type of the tool. Before
starting the engine, check that the tiller is not damaged and in good
condition. For your safety and safety of others, exercise extreme care
when using the tiller on up or down hill.

Gasoline spoils very quickly depending on factors such as light
exposure, temperature and time.
In worst cases, gasoline can be contaminated within 30 days.
Using contaminated gasoline can seriously damage the engine
(carburetor clogged, valve stuck).
14
Such damage due to spoiled fuel is disallowed from coverage by the
warranty.
To avoid this please strictly follow these recommendations:
Only use specified gasoline (see page ).
14
Use fresh and clean gasoline.
To slow deterioration, keep gasoline in a certified fuel container.
If long storage (more than 30 days) is foreseen, drain fuel tank and
carburetor (see page ).
35
Gasolines containing alcohol
If you decide to use a gasoline containing alcohol (gasohol), be sure it’s
octane rating is at least as high as that recommended by Honda. There
are two types of ‘‘gasohol’’: one containing ethanol, and the other
containing methanol.
Do not use gasohol that contains more than 10% ethanol. Do not use
gasoline containing methanol (methyl or wood alcohol) that does not
also contain cosolvents and corrosion inhibitors for methanol.
Never use gasoline containing more than 5% methanol, even if it has
cosolvents and corrosion inhibitors.
Fuel system damage or engine performance problems resulting
from the use of gasoline that contains alcohol is not covered under
the warranty.
Honda cannot endorse the use of gasoline containing methanol
since evidence of its suitability is as yet incomplete.
Before buying gasoline from an unfamiliar station, first determine if
the gasoline contains alcohol; if it does, find out the type and
percentage of alcohol used.
If you notice any undesirable operating symptoms while using a
gasoline that contains alcohol, or one that you think contains
alcohol, switch to a gasoline that you know does not contain alcohol.

Check tire pressures. lmproper inflation can
reduce both tire life and load carrying capacity.

High altitude operation
At high altitude, the standard carburetor air-fuel mixture will be
excessively rich. Performance will decrease, and fuel consumption will
increase.
High altitude performance can be improved by specifications to the
carburetor. If you always operate the tiller at altitude higher than
1,500 m (5,000 feet) above sea level, have your authorized Honda
dealer perform these carburetor modifications.
Even with suitable carburetor jetting, engine horsepower will decrease
approximately 3.5 % for each 300 m (1,000 feet) increase in altitude.
The effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
Operation of the tiller at an altitude lower than the carburetor is jetted
for may result in reduced performance, overheating, and serious engine damage caused by an excessively lean air-fuel mixture.
