MOWER SAFETY

IMPORTANT SAFETY INFORMATION

Most accidents with walk-behind mowers can be prevented if you
follow all instructions in this manual and on the mower. The most
common hazards, according to accident statistics, are discussed
below, along with the best way to protect yourself and others.

Avoid Rotating Blades

Rotating blades can cause serious cuts and even amputate fingers,
hands, toes, or feet. Keep away from the mower deck whenever the
engine is running. If you need to adjust the cutting height, or work
around the deck for any other reason, always shut off the engine.
Wear heavy gloves and disconnect the spark plug cap when you need
to clean the mower deck or handle the blade.

Clear Mowing Area

Mower blades can throw rocks and other objects with enough force to
cause serious injury. Before mowing, carefully inspect the area and
remove all sticks, stones, pieces of wire, and other loose objects.
Never operate the blade over gravel.

Keep Shields in Place

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

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.

Turn Engine Off When Not Mowing

If you need to leave the mower for any reason, even just to inspect
the lawn ahead, always turn the engine OFF.

MOWER SAFETY

IMPORTANT MESSAGE TO PARENTS

YOUR CHILDREN’S SAFETY IS VERY IMPORTANT to Honda.
That’s why we urge you to read this message before letting your
youngster operate this lawn mower. Lawn mowers are tools, not toys.
As with any equipment, bad judgments can result in serious injuries.
You can help prevent accidents by making good decisions about if,
when, and how your youngster operates this equipment.

The first question you’ll need to ask is whether your youngster is
capable of operating this mower safely. Remember, young people
vary widely, and AGE IS NOT THE ONLY FACTOR.

Physically, a youngster must be LARGE ENOUGH AND STRONG
ENOUGH to easily start the mower and control its direction. The
youngster also needs enough size, strength, and coordination to
comfortably reach and operate the controls.

Another, tougher question you need to ask is if your youngster has
enough MATURITY AND RESPONSIBILITY to safely operate this
mower. Does the young person think through problems and come to
logical solutions? Be honest! Anyone who takes unnecessary risks
and doesn’t obey rules should not operate this lawn mower.

If you decide that your son or daughter can handle the mower safely,
CAREFULLY READ THE OWNER’S MANUAL with your youngster.
Make sure you both understand all instructions and safety information.
Also, be sure your youngster wears sturdy shoes and other protective
clothing when operating or handling the mower.

SUPERVISION is also very important. Walk with your youngster
during the first few minutes of mowing. Even after the youngster has
become confident with the mower, do not let the young person use
the mower without good adult supervision. An adult should also be
present during refueling and maintenance. In fact, it’s up to parents to
make sure that the mower is properly maintained and kept in safe
operating condition.

By always placing safety first, your youngster will acquire useful skills
and a sense of accomplishment. And you’ll both get the best results
from your lawn mower.

BEFORE OPERATION

ARE YOU READY TO MOW?

Be sure to wear protective clothing. Long pants and eye protection
can lower your risk of injury from thrown objects. Wear footwear
that protects your feet and won’t let you slip if you mow on slopes
or uneven ground.

CHECK YOUR LAWN

For your safety and for the safety of others, always inspect the
area before mowing.

Objects

Anything which can be picked up by the blade and thrown is a
potential hazard to you and others. Look for things like stones,
sticks, bones, and wire. Remove them from the mowing area.

People and Pets

People and animals near the mowing area can move into your
path or into a position where they could be struck by thrown
objects. Clear the area of people and pets, especially children.
Their safety is your responsibility.

Lawn

Check the length and condition of the grass, so you will know what
cutting height and mowing speed to use.

Avoid mowing wet grass. Not only will wet grass clog your mower
deck and collect in clumps on the lawn, it also gives poor traction,
increasing your risk of losing your footing.

OPERATION

MOWING PRECAUTIONS

Before operating the mower for the first time, please review the
MOWER SAFETY beginning on page 4 and the previous chapter,
titled BEFORE OPERATION.

Even if you have operated other mowers, take time to become
familiar with how this mower works and practice in a safe area
until you build up your skills.

For your safety, avoid starting or operating the engine in an
enclosed area such as a garage. Your mower’s exhaust contains
poisonous carbon monoxide gas which can collect rapidly in an
enclosed area and cause illness or death.

STARTING THE ENGINE

The blade turns when you operate the starter. It is easiest to start the
engine in a clear or mowed area where the blade can turn freely.

1. Turn the fuel valve to the ON position.

OPERATING THE CONTROLS FOR MOWING

Throttle Lever

For best cut quality, always mow with the throttle lever in the FAST
position. When the blade rotates at the preset fast speed, it creates a
strong fan action that lifts and cuts grass more efficiently. Do not try to
increase the preset engine speed, the blade could fracture and come
apart.

FAST

When you need to leave the mower for any reason, always turn
the engine OFF by releasing the flywheel brake lever.

Flywheel Brake Lever

The lever must be pulled
backward against the handlebar to
start the engine. The blade starts
to rotate when the lever is pushed
forward against the handlebar and
the recoil starter grip is pulled.

Continue to hold the lever against
the handlebar to keep the engine
running and the blade rotating.

Release the lever to stop the
engine and stop blade rotation.

SAFE MOWING PRACTICES

For your safety, keep all four wheels on the ground, and be careful to
avoid losing your footing and your control of the mower. Keep a firm
grip on the handlebar, and walk, never run, with the mower. Be very
careful when mowing uneven or rough ground.

If stuck, do not kick or shove the mower with your foot. Use the
handlebar to control the mower.

WARNING

The blade is sharp and spins at high speed.
A spinning blade can cut you severely and

can amputate fingers and toes.

• Wear protective footwear.

• Keep your hands and feet away from the

mower deck while the engine is running.

• Stop the engine before performing any
adjustment, inspection, or maintenance.

Slopes

Mow across slopes, not up
and down. Avoid steep slopes
(more than 20°), and be
careful when changing
direction. Mowing on a slope
when the grass is damp or
wet could cause you to slip,
fall, and lose control of the
mower.

MAXIMUM SLOPE 20 °

OPERATION

Obstacles

Use the side of the mower to cut close to large obstacles, such as
fences or walls.

Release the drive clutch lever to disengage the drive when mowing
around trees and other obstacles. Push the mower around obstacles
for better directional control. Be careful when mowing over obstacles
embedded in the lawn, such as sprinkler heads, paving, edging, etc.
Avoid anything that sticks up above the surface of the lawn.

If the blade hits something, or if the mower starts to vibrate, stop the
engine immediately, disconnect the spark plug cap, and check for
damage (see page 12). Striking objects may damage the blade, bend
the crankshaft, and/or break the mower deck or other components.
Vibration usually indicates serious trouble.

WARNING

A worn, cracked, or damaged blade can
break, and pieces of the damaged blade can
become dangerous projectiles.

Thrown objects can cause serious injury.
Inspect the blade regulary, and od not

operate the mower with a worn or damaged
blade.

The Distributor’s Limited Warranty does not cover parts damaged by
accident or collision.

Gravel and Loose Objects

Gravel, loose stones, and landscaping material can be picked up by
the mower and thrown many feet with enough force to cause serious
personal injury and/or property damage. The best way to prevent
potential injury from thrown objects is to release the flywheel brake
lever to stop the blade before reaching areas with gravel, loose
stones, or landscaping material.

23

OPERATION

MOWING TIPS

When to Mow

Most grasses should be mowed
when they have grown
above their recommended height.

More frequent mowing is required
for mulching than for bagging. For
best results, you may need to
mow the lawn twice a week during
the growing season.

Cutting Height

Consult a local nursery or lawn
and garden center for cutting
height recommendations and
advice about specific types of
grasses and growing conditions in
your area.

If you look closely, you’ll see that
most grass has stems and leaves.
If you cut off the leaves, you’ll
scalp the lawn. Let the grass
recover between mowings. Your
mower will work better, and your
lawn will look better.

to 1 inch

LONG ENOUGH

TOO SHORT

If your grass gets too tall, cut it once at the highest cutting height
setting, then mow again in 2 or 3 days. Don’t take off more than one
third of total grass height in any one mowing, or brown patches may
develop.

Cutting height adjustment is explained on page 10.

Cutting Width

For an even lawn finish, overlap each mowing swath by a few inches.
If the grass is very tall or thick, use more overlap and a narrower
mowing swath.

24

OPERATION

Blade Speed

The blade must spin very fast to cut properly. Always use the
FAST throttle setting. If engine speed drops, it could mean the
engine is being overloaded by the blade trying to cut too much
grass. Mow a narrower swath, move the mower slower, install the
discharge cute, or raise the cutting height.

Blade Sharpness

A sharp blade cuts cleanly. A dull blade tears the grass, leaving
shredded ends that turn brown. When your blade doesn’t cut
cleanly anymore, have it sharpened or replaced.

Dry Grass

If the ground is too dry, mowing will stir up a lot of dust. Besides being
unpleasant to work in, too much dust will clog the carburetor air filter.
If dust is a problem, water your lawn the day before mowing. Mow
when the grass is dry to your touch, but the soil is still moist.

Wet Grass

Wet grass is slippery and can make you lose your footing. Also,
wet grass clippings will clog the mower deck and collect in clumps
on the lawn. Always wait for wet grass to dry before mowing.

Fallen Leaves

When equipped with the optional grass bag, your mower can be
used to pick up fallen leaves for disposal. If using the mower to
bag large amounts of fallen leaves, and not for mowing, set the
cutting height adjustment levers so the front of the mower deck is
one or two settings higher than the rear.

If you want to mulch fallen leaves into your lawn, don’t let the leaf
cover get too deep before you begin. For best results, start
mulching while grass still shows through the leaf cover. In places
where fallen leaves completely cover the grass, remove the
leaves by raking, or install a grass bag, so your mower can pick
them up for disposal.

Clogged Mower Deck

Before clearing a clogged mower deck, stop the engine and turn
the fuel valve to the OFF position. With the spark plug cap
disconnected, tilt the mower so the carburetor side is up.
Clear a clogged deck with a stick, not your hands.

25

OPERATION

Mowing Patterns

Your Honda mower will work most efficiently if you use the following
mowing patterns as much as possible. Mower deck and equipment
design, and the direction in which the blade rotates, cause these
mowing patterns to give the best results.

Mulching

Use a counterclockwise mowing
pattern. If the lawn has an
irregular shape, or many
obstacles, divide it into sections
where you can use
counterclockwise mowing
patterns.

Side-Discharge Mowing

Where possible, use the same
mowing pattern recommended for
mulching. If the lawn has an
irregular shape, or many
obstacles, divide it into sections
where clippings will be discharged
away from uncut areas. This will
prevent clippings from piling up in
the path of the mower.

MULCHING & SIDE
DISCHARGE PATTERN

Bagging

(Requires optional grass bag kit)

Use a clockwise mowing pattern.
This will give the best bagging
performance, leaving the least
amount of clippings on the lawn.

26

BAGGING PATTERN

TRANSPORTING

BEFORE LOADING

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

Turn the fuel valve to OFF. This will prevent carburetor flooding and
reduce the possibility of fuel leakage.

OFF

FUEL VALVE

If equipped, remove the grass bag.

LOADING AND UNLOADING

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

Position the mower so all four wheels are on the bed of the transport
vehicle. Tie the mower down with rope or straps, and block the
wheels. Keep the tie-down rope or straps away from the controls,
adjustment levers, cables, and the carburetor.

The handlebar can be folded so the mower will take up less space
(see page 43).

27

MAINTENANCE

THE IMPORTANCE OF MAINTENANCE

Good maintenance is essential for safe, economical, and trouble-free
operation. It will also help reduce air pollution.

WARNING

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.

To help you properly care for your mower, 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 mower under severe
conditions, such as sustained high-load or high-temperature
operation, or use in unusually wet or dusty conditions, consult your
servicing dealer for recommendations applicable to your individual
needs and use.

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.

28

MAINTENANCE

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.

WARNING

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

Always follow the procedures and
precautions in this 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.

Remember that an authorized Honda servicing dealer knows your
mower 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

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 lean carburetor settings and other systems to reduce
the emissions of carbon monoxide, oxides of nitrogen, and
hydrocarbons.

The U.S and California Clean Air Acts

EPA and California 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 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 the intake, fuel, or exhaust
systems.

•

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 servicing dealer.

•

Hard starting or stalling after starting.

•

Rough idle.

•

Misfiring or backfiring under load.

•

Afterburning (backfiring).

•

Black exhaust smoke or high fuel consumption.

30

MAINTENANCE

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 32. 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.

ENGINE MAINTENANCE

Engine Oil Change

Drain the used oil while the engine is warm. Warm oil drains
quickly and completely.

1. Turn the fuel valve to OFF to reduce the possibility of fuel leakage
(see page 21).

2. Wipe the oil filler area clean, then remove the oil filler cap/dipstick.

3. Place a suitable container next

to the mower to catch the used
oil, then tilt the mower on its
right side. The used oil will drain
through the filler neck. Allow the
oil to drain completely.

Please dispose of used motor
oil and the containers in a
manner that is compatible with
the environment. We suggest
you take it in a sealed container
to your local recycling center or
service station for reclamation.
Do not throw it in the trash, pour
it on the ground or down a
drain.

4. Fill with the recommended oil.

Do not overfill; measure the oil
level as shown on page 34.

Engine oil capacity:

0.58 US qt. (0.55 l)

NOTICE

Using nondetergent oil can shorten the engine’s service life, and
using 2-stroke oil can damage the engine.

33

MAINTENANCE

5. After changing the engine oil, and before starting the engine, check
the oil level with the mower on a level surface:

a. Wipe the dipstick clean.
b. Insert and remove the

dipstick without screwing it
into the filler neck. Check the
oil level shown on the
dipstick.

c. If the oil level is low, add oil to

reach the upper limit mark on
the dipstick. Do not overfill. If
the engine is overfilled, the
excess oil may get
transferred to the air cleaner
housing and air cleaner filter.

NOTICE

Running the engine with a
low oil level can cause
engine damage.

MAINTENANCE

Air Cleaner Service

A dirty air filter restricts air flow to the carburetor, reducing engine
performance. If you operate the mower in very dusty areas, clean
the air filter more often than specified in the MAINTENANCE
SCHEDULE.

NOTICE

Operating the engine without an air filter, or with a damaged filter,
will allow dirt to enter the engine, causing rapid engine wear. This
type of damage is not covered by the Distributor’s Limited

Warranty.

1. Press down on the cover tabs, then remove the cover. Remove the
filter and inspect it; if damaged, replace the filter.

AIR CLEANER HOUSING

FILTER

COVER

2. Clean the filter by tapping the filter several times on a hard surface
to remove dirt, or blowing compressed air (not exceeding 30 psi
[207 kPa]) through the filter from the inside. Never try to brush off
dirt; brushing will force dirt into the fibers.

3. Wipe dirt from the inside of the air cleaner housing and cover, using
a moist rag. Be careful to prevent dirt from entering the air duct that
leads to the carburetor. Reinstall the filter and cover.

Flywheel Brake Lever Operation Inspection.

Start the engine outdoors and move the throttle to FAST. Release
the flywheel brake lever; the engine should stop quickly. If it does
not, take your mower to an authorized Honda servicing dealer for
repair.

35

MAINTENANCE

Spark Plug Service

Refer to page 46 for replacement spark plug numbers.

NOTICE

An incorrect spark plug can cause engine damage.
For good performance, the spark plug must be properly gapped and

free of deposits.

1. Disconnect the spark plug cap
and remove dirt from the area.
Use a spark plug wrench to
remove the spark plug.

2. Inspect the plug; replace it if the
electrodes are worn, or if the
insulator is cracked or chipped.
Clean plug completely if you
are going to reuse it.

3. Set the gap to 0.028 ~ 0.031 in
(0.7 ~ 0.8 mm).

4. After the plug seats, tighten it
as follows to seat the washer:

MAINTENANCE

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.
High altitude performance can be improved by specific modifications
to the carburetor. If you always operate your mower at altitudes above
5,000 feet (1,524 meters) have an authorized Honda servicing dealer
perform this carburetor modification. 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.

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 (1,524 meters) with a modified carburetor
may cause the engine to overheat and result in serious engine
damage. For use at low altitudes, have an authorized Honda servicing
dealer return the carburetor to original factory specifications.

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. 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 knock or
pinging persists, see an authorized Honda servicing dealer.

NOTICE

Running the engine with persistent spark knock or pinging can cause
engine damage. Running the engine with persistent spark knock or
pinging is misuse, and the Distributor’s Limited Warranty does not
cover parts damaged by misuse. For oxygenated fuel information
refer to page 56.

MAINTENANCE

BLADE REMOVAL AND INSTALLATION

If you remove the blade, use a torque wrench for installation. Wear
heavy gloves to protect your hands. To avoid weakening the blade, or
causing imbalance or poor cutting, the blade should be sharpened by
trained staff at an authorized Honda servicing dealer. If replacing the
blade, use a genuine Honda replacement blade or equivalent.

1. Removal:Turn the fuel valve to OFF. Disconnect the spark plug
cap, then tilt the mower to the right side, carburetor side up.

2. Remove the two blade bolts with a 14 mm socket. Use a wooden
block to prevent the blade from turning when removing the bolts.
Remove the blade from the blade holder.

3. Installation:Clean around the blade holder. Install the blade using
the bolts and special washers exactly (concave side of the special
washers toward the blade) as shown.

If you don’t have a torque wrench, have an authorized Honda
servicing dealer tighten the blade bolts before you use the mower. If
the blade bolts are overtightened, they could break. If the blade bolts
are not tightened enough, they could loosen or come out. In either
case, it would be possible for the blade to fly off while you are

STORAGE

STORAGE PREPARATION

Proper storage preparation is essential for keeping your lawn mower
troublefree and looking good. The following steps will help to keep
rust and corrosion from impairing your lawn mower’s function and
appearance, and will make the engine easier to start when you use
the lawn mower again.

Cleaning

1. Wash the lawn mower, including the underside of the mower deck.

Engine

Wash the engine by hand, and be careful to prevent water from
entering the air cleaner.

NOTICE

Using a garden hose or pressure washing equipment can force

•

water into the air cleaner. Water in the air cleaner will soak the
filters and can enter the carburetor or engine, causing damage.

Water on a hot engine can cause damage. If the engine has been

•

running, allow it to cool for at least 1/2 hour before washing.

Mower Deck

If using a garden hose or pressure washing equipment to clean the
mower deck, be careful to avoid getting water into controls and
cables, or anywhere near the engine air cleaner or muffler opening.

Before washing the underside of the mower deck, be sure the fuel
valve is in the OFF position. Disconnect the spark plug cap. Rest
the mower on its right side, so the carburetor side is up. This will
help to prevent fuel leakage and hard starting due to carburetor
flooding. Wear heavy gloves to protect your hands from the blade.

2. After washing the lawn mower, wipe dry all accessible surfaces.

3. With the mower in an upright position, start the engine outdoors,
and let it run until it reaches normal operating temperature to
evaporate any water remaining on the engine.

4. Stop the engine and allow it to cool.

5. After the lawn mower is clean and dry, touch up any damaged
paint, and coat other areas that may rust with a light film of oil.
Lubricate the control cable cores with a silicone spray lubricant.

41

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 mower 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 fuel stabilizer to extend fuel storage life

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. If you keep a container of gasoline for refueling, be sure that
it contains only fresh gasoline.

1. Add fuel stabilizer following the manufacturer’s instructions.

2. After adding a fuel 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. This
turns off the fuel flow between the fuel tank and the carburetor.

42

STORAGE

Draining the Fuel Tank and Carburetor

1. Remove the carburetor drain bolt with a 10 mm wrench, and drain
the carburetor bowl fuel into an approved container.

WARNING

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.
Handle fuel only outdoors.

•

2. Turn the fuel valve ON (see
page 9). This will allow fuel in
the fuel tank to drain through
the carburetor bowl. After the
fuel is completely drained,
reinstall the drain bolt.

DRAIN BOLT

Engine Oil

Change the engine oil (see page 33).

Engine Cylinder

Remove the spark plug (see page ). Pour a tablespoon (5 ~ 10 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 closes the valves so moisture cannot enter.

Handlebar Folding

Remove the grass bag (if
installed). Loosen the handlebar
locking knobs. Press the
handlebar struts to release the
locating pins, then swing the
handlebar forward. Don’t allow the
cables to be bent or pinched.

LOCKING KNOB

43

STORAGE

STORAGE PRECAUTIONS

If your mower 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, turn the fuel valve
to OFF to reduce the possibility of fuel leakage.

Place the mower with its wheels on a level surface. Tilting can cause
fuel or oil leakage.

The handlebar can be folded for compact storage (see page 43).
With the engine and exhaust system cool, cover the mower 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 mower, promoting rust and
corrosion.

REMOVAL FROM STORAGE

Check your mower as described in the BEFORE OPERATION
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 will smoke briefly at startup. This is normal.

Emission Control System Warranty

Your new Honda Power Equipment engine complies with both the U.S. EPA and
State of California emission regulations. American Honda provides the same
emission warranty coverage for engines sold in all 50 states.

Your Warranty Rights And Obligations:

California

The California Air Resources Board and American Honda Motor Co., Inc. are pleased to
explain the emission control system warranty on your Honda Power Equipment engine.
In California, new utility and lawn and garden equipment engines must be designed, built
and equipped to meet the State’s stringent anti-smog standards.

Other States

In other areas of the United States your engine must be designed, built, and equipped
to meet the U.S. EPA Phase I Emission standard for spark ignited engines at or
below 19 kilowatts.

All States

American Honda Motor Co., Inc. must warrant the emission control system on your
power equipment engine for the period of time listed below provided there has been
no abuse, neglect or improper maintenance of your power equipment engine. Where
a warrantable condition exists, American Honda Motor Co., Inc. will repair your power
equipment engine at no cost to you including diagnosis, parts and labor.

Your emission control system may include such parts as the carburetor or fuel
injection system, the ignition system, and catalytic converter. Also included may be
hoses, connectors and other emission-related assemblies.

Manufacturer’s Warranty Coverage:

The 1995 and later power equipment engines are warranted for two years. If any
emission-related part on your engine is defective, the part will be repaired or replaced
by American Honda Motor Co., Inc.

Owner’s Warranty Responsibility:

As the power equipment engine owner, you are responsible for the performance of the
required maintenance listed in your owner’s manual. American Honda Motor Co., Inc.
recommends that you retain all receipts covering maintenance on your power equipment
engine, but American Honda Motor Co., Inc. cannot deny warranty coverage solely for the
lack of receipts or for your failure to ensure the performance of all scheduled maintenance.

As the power equipment engine owner, you should however be aware that American
Honda Motor Co., Inc. may deny you warranty coverage if your power equipment
engine or a part has failed due to abuse, neglect, improper maintenance, or
unapproved modifications.

You are responsible for presenting your power equipment engine to a Honda Power
Equipment dealer as soon as a problem exists. The warranty repairs should be
completed in a reasonable amount of time, not to exceed 30 days.

If you have any questions regarding your warranty rights and responsibilities, you
should write or call the Honda Power Equipment Customer Relations Department.
Refer to page for contact information.

ADDITIONAL INFORMATION

Warranty Coverage:

Honda power equipment engines manufactured after January 1, 1995 and sold in the
State of California, and U.S. EPA certified engines manufactured on or after
September 1, 1996 and sold in all of the United States, are covered by this warranty
for a period of two years from the date of delivery to the original retail purchaser. This
warranty is transferable to each subsequent purchaser for the duration of the
warranty period.

Warranty repairs will be made without charge for diagnosis, parts or labor. All
defective parts replaced under this warranty become the property of American Honda
Motor Co., Inc. A list of warranted parts is on the reverse side of this warranty
statement. Normal maintenance items, such as spark plugs and filters, that are on the
warranted parts list are warranted up to their required replacement interval only.

American Honda Motor Co., Inc. is also liable for damages to other engine components
caused by a failure of any warranted part during the warranty period.

Only Honda approved replacement parts may be used in the performance of any
warranty repairs and must be provided without charge to the owner. The use of
replacement parts not equivalent to the original parts may impair the effectiveness of
your engine emission control system. If such a replacement part is used in the repair
or maintenance of your engine, and an authorized Honda dealer determines it is
defective or causes a failure of a warranted part, your claim for repair of your engine
may be denied. If the part in question is not related to the reason your engine requires
repair, your claim will not be denied.

To Obtain Warranty Service:

You must take your Honda Power Equipment engine or the product on which it is
installed, along with your warranty registration card or other proof of original purchase
date, at your expense, to any Honda Power Equipment dealer who is authorized by
American Honda Motor Co., Inc. to sell and service that Honda product during his
normal business hours. Claims for repair or adjustment found to be caused solely by
defects in material or workmanship will not be denied because the engine was not
properly maintained and used.

If you are unable to obtain warranty service, or are dissatisfied with the warranty
service you received, contact the owner of the dealership involved. Normally this
should resolve your problem. However, if you require further assistance, write or call
the Power Equipment Customer Relations Department of American Honda Motor Co.,
Inc. Refer to page for contact information.

ADDITIONAL INFORMATION

OXYGENATED 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. Bfore 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 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 cosolvents
and corrosion inhibitors to protect the fuel system.
Gasoline containing more than 5% methanol by
volume may cause starting and/or performance
problems. It 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.

HONDA PUBLICATIONS

Two other documents are availble from your Honda dealer. There is a
Shop Manual, which covers complete maintenance and overhaul
procedures. It is intended to be used by a skilled technician. There is
also a Parts Catalog, that provides a complete, illustrated parts lists.

ADDITIONAL INFORMATION

SPARK ARRESTER SERVICE (optional equipment)

Your lawn mower engine is not factory-equipped with a spark
arrester. In some areas, it is illegal to operate an engine without a
spark arrester. Check local laws and regulations. An optional
USDA approved spark arrester is available from an authorized
Honda servicing dealer.

The spark arrester must be serviced every 100 hours to keep it
functioning as designed.

1. Allow the engine to cool, then remove the bolts from the muffler
shield. Remove the muffler shield.

2. Loosen the two set screws and remove the spark arrester.

3. Check for carbon deposits on the spark arrester and the exhaust
port. Brush carbon deposits away. Be careful to avoid damaging
the spark arrester screen.

4. Installation is the reverse of removal. Tighten all hardware securely.
