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 exhaust 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
exhaust
gas. To keep exhaust gas from building up, provide adequate
ventilation.
5
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 a 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 area; stop the tiller. Never operate the
tines over gravel.
6
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
IO".
Before starting
the engine, check that the tiller is not damaged and is
in
good
condition. For your safety and safety of others, exercise extreme
care when using the tiller on
a
slope.
Tilling Conditions
Operate 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 preoperation inspection
before each operation, and correct any
problem.
13
BEFORE OPERATION
Do
not place flammable objects close to the engine.
Before beginning your preoperation 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
30).
Check the air filter (see page
34).
A
dirty air filter
will
restrict air flow
to the carburetor, reducing engine and tiller performance.
Check the fuel level (see page
28).
Starting with a full tank will help
to eliminate or reduce operating interruptions for refueling.
Check the Tiller
Check the transmission oil (see page
33).
OPERATION
SAFE OPERATING PRECAUTIONS
Before operating the tiller for the first time, please review both the
TlLLER SAFETYchapter 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 which 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.

HANDLING
TIPS
Adjust the handle bar 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
handle bars. 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
handle bars 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, genuine
Honda 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.

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
nonflammable solvent, not
gasoline, to clean parts. Keep cigarettes, sparks, and flames away
from all fuel-related parts.
Disconnect the spark plug cap and wear
working near the belts, or tine blades. heavy gloves when

REFUELING
Fuel tank capacity:
1.19
US
gal
(4.51)
With the engine stopped, remove the fuel tank cap and check the fuel
level. Refill the tank if the fuel level is low.
Do
not fill above the fuel
level mark.
Gasoline is
highly
flammable and explosive.
You can be burned or seriously injured when
handling fuel.
Stop the engine and keep heat, sparks, and
flame away.
Refuel only outdoors.
Wipe
up
spills immediately.
Refuel
in
a well-ventilated area before starting the engine. If the
engine has been running, allow
it
to cool. Refuel carefully to avoid
spilling fuel.
Do
not fill the fuel tank above the fuel level mark. After
refueling, tighten the fuel tank cap securely.
Never refuel the engine inside a building where gasoline fumes may
reach flames or sparks. Keep gasoline away from appliance pilot
lights, barbecues, electric appliances, power tools, etc.
Spilled fuel is not only
a
fire hazard,
it
causes environmental damage.
Wipe up spills immediately.
FUEL RECOMMENDATIONS
Use unleaded gasoline with a pump octane rating
of
86
or higher.
This engine is certified to operate on unleaded gasoline. Unleaded
gasoline produces fewer engine and spark plug deposits and extends
exhaust system life.
SERVICING
YOUR
TILLER
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Occasionally you may hear light "spark knock" or "pinging" (metallic
rapping noise) while operating under heavy loads. This is no cause
for concern.
If spark knock or pinging occurs
at
a
steady engine speed, under
normal load, change brands of gasoline.
If
spark

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.
piK
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.
pEE
Spraying water on hot tine shaft bearings can cause them to be
damaged from cooling too quickly.
46
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.
47
STORAGE
Fuel
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.
The Distributor's Limited Warranty does not cover fuel system
damage or engine performance problems resulting from neglected
storage preparation.
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
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 of 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.

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.
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 around the tiller, promoting rust and
corrosion.
REMOVAL FROM STORAGE
Check your tiller as described in the
BEFORE
OPERATlON
chapter of
this manual.
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.
51
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.

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 performanice 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 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
effect of altitude on horsepower will be greater than this if no
carburetor modification is made.
pEi5
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
(7,500
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

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
United States 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 are the EPA approved percentages of oxygenates:
ETHANOL
-
(ethyl or grain alcohol) 10% by volume
You may use gasoline containing up to 10% ethanol by
volume. Gasoline containing ethanol may be marketed
under the name "Gasohol".
MTBE (Methyl Tertiary Butyl Ether) 15% by volume
You may use gasoline containing up to 15% MTBE by

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 cosolvents and
corrosion inhibitors to protect the fuel system.
Gasoline containing more than
5%

and California Clean Air Act
EPA
and California regulations require all manufacturers to furnish
written instruction describing the operation and maintenance
of
emission control systems.
The following instructions and procedures must be followed in order
to keep the Honda engine emissions within the emission standards.
Tampering an Altering
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.

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 EPA and California
emission regulations.
We recommend the use of genuine Honda 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
27.
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.
