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 lawn mower and its operation before you
begin using it. Know how to quickly shut off the lawn mower in case of
an emergency.
IS YOUR LAWN MOWER READY TO GO?
For your safety, and to maximize the service life of your lawn mower, it
is very important to take a few moments before you operate the lawn
mower 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
lawn mower.
Before beginning your pre-operation checks, be sure the lawn mower
is on a level surface.
WARNING
Improperly maintaining this lawn mower, 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.

Check the General Condition of the Lawn Mower:
• Look around and underneath the lawn mower for signs of oil or
gasoline leaks.
• Look for signs of damage.
• Check each control for proper operation.
• Check the blade for wear. Replace as necessary (page 29). Check
that the blade bolts are tight (page 30).
• Check that all nuts, bolts, screws are tightened.
Check the Engine
• Check the air cleaner (page 34) and oil level (page 32).
• Check the fuel level (page 38). Starting with a full tank will help to
eliminate or reduce operating interruptions for refueling.
CHECK YOUR WORK AREA
For your safety and the safety of others, always inspect the area
before operating the lawn mower.
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, nails, and
wire, and remove them from the work area.
People and Pets
People and animals near the work area can move into your lawn
mower’s path or into a position where they could be struck by thrown
objects. Clear the area of people, especially children and pets. Their
safety is your responsibility.
Work Area
Check the condition of the grass. Adjust your lawn mower ground
speed and mowing swath accordingly.

Cutting Height
Set all four adjustment levers [1] to
the same cutting height position.
Each position changes the height
approximately 13 mm.
To adjust cutting height, pull each
adjustment lever toward the wheel,
and move it into another notch.
If you are not sure what cutting
height to select, start with a high
setting and check the appearance of the lawn after mowing a small
area. Readjust cutting height if necessary.

Grass Bag
A lawn mower works like a vacuum cleaner; it blows air through the
bag, which traps the grass clippings. Always empty the grass bag
before it becomes filled to the limit of its capacity. Bagging
performance will diminish after the bag becomes about 90% full. Also,
the bag is easier to empty when not packed full.
Inspection
Inspect the grass bag before use. Check for holes, tears, and
excessive wear. The grass bag does wear during normal use, and will
eventually require replacement (page 31).
Installation
1. Raise the rear discharge guard [1],
grasp the grass bag handle [2] and
hook the grass bag frame onto the
mower deck as shown.
2. Release the rear discharge guard
to secure the grass bag in place.
Removal
1. Raise the rear discharge guard,
grasp the grass bag handle and
remove the grass bag.
2. Release the rear discharge guard.
3. When the grass bag is clear of the rear discharge, you can lift the
grass bag through the handlebars, or remove it from the rear of the
mower below the handlebar.

OPERATION
MOWING PRECAUTIONS
Before operating the mower for the first time, please review the LAWN
MOWER SAFETY chapter beginning on page 3 and the BEFORE
OPERATION chapter beginning on page 11.
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 pull the starter grip. It is easiest to start the
engine in a clear or mowed area where the blade can turn freely.
1. Turn the fuel valve [1] to the ON [2] position.
2. Move the throttle lever [3] to the CHOKE [4] position for a cold
engine, or FAST [5] for a warm engine.

Keep your hands and feet away
from the mower deck at all
times when starting and running
the engine.
Continue to hold the flywheel
brake lever against the
handlebar; the engine will stop if
you release the lever.
6. If the CHOKE [4] position was
used during starting, move the
throttle lever away from the
CHOKE position as soon as the
engine warms up enough to run
smoothly. Set the throttle lever

OPERATING THE CONTROLS FOR MOWING
Throttle Lever
For best cut quality, always mow with the throttle lever [1] in the FAST
[2] 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.
When you need to leave the mower for any reason, move the throttle
to SLOW, then turn the engine OFF by releasing the flywheel
brake lever.
Flywheel Brake Lever
The flywheel brake lever [3] must
be pulled back against the
handlebar to start and run the
engine. The blade starts to rotate
when the lever is pulled back
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.

Drive Clutch Lever
Push the drive clutch lever [4]
forward and hold it against the
handlebar to propel the mower
forward.
Release the drive clutch lever to
stop the mower’s forward
movement.
Always release the drive clutch
lever before starting the engine. If
the drive clutch is engaged, the
mower will move forward when you operate the starter.
Operate the drive clutch lever with a quick and complete motion, so the
drive clutch is either fully engaged or fully released. Hold the drive
clutch lever against the handlebar during self-propelled mowing. This
will help to extend the service life of the clutch mechanism.
Shift Lever
Use the shift lever to adjust the
forward speed of the mower. Do
not use the throttle lever; the
throttle lever must be kept in the
FAST position for the best
mowing performance.
You may move the shift lever
anytime; however, if the mower
is pulling hard, release the drive
clutch lever between shifts for
smooth operation.
Gears 1 and 2 are
recommended for maximum
mowing performance. Gear 3
should be used to transport the mower.

Caster Wheel Lock Lever
Use the caster wheel lock lever [1] to hold the front wheels in the
straight ahead direction. The lock lever can be moved anytime while
moving forward; however, if the lever is difficult to move to the
RELEASE position [2], do not force it. Push down on the handlebar
enough to raise the front wheels off the ground to release pressure on
the locking pins. Then move the lever to the RELEASE position.
The LOCK position [3] must be used when mowing across slopes or
when straight cutting paths are desired. The RELEASE position is
recommended for maximum maneuverability on level terrain.
With the lever in the RELEASE position [2], push the mower forward
then move the lock lever to the LOCK position [3]. This will lock the
wheels in the trailing position [4] and prevent the wheels from getting
locked in the leading position [5].
If the wheels are locked in the leading position, cut quality may suffer
and additional stress may be transferred to the mower causing mower
damage.
NOTICE
If the mower is operated with the front wheels locked in the leading
position, mower damage may result.

SAFE MOWING PRACTICES
For your safety, keep all four wheels on the ground, and be careful to
avoid losing your footing and 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 push the
mower with your foot. Use the handlebar only.
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.
IMPORTANT SAFETY PRECAUTION
Always have the front wheels in the
LOCK position and completely locked when on a slope (page 9). This
will improve mower control and, if the mower is left unattended on the
slope, it will prevent the mower from turning and going down the slope
and possibly injurying someone.
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.

E
Obstacles
Use the side of the mower to cut close to 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 sticking 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 (page 29). Striking objects may damage the blade, bend the
crankshaft, and/or break the mower deck or other components.
Vibration usually indicates serious trouble.
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.
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(s) regularly, and do not operate
the mower with a worn or damaged blade.

MOWING TIPS
When to Mow
Most grasses should be mowed when they have grown ½ to 1 inch
above their recommended height. More frequent mowing is required
for mulching than for bagging. For best mulching 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.
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.
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.
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 chute,
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.
1E-HRZ536C.book Page 23 Thursday, September 8, 2005 11:16 AM
OPERATION
24
E
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 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 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.

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 (with optional mulching plug)
Use a counterclockwise mowing pattern.
If the lawn has an irregular shape, or
many obstacles, divide it into sections
where you can use counterclockwise
patterns.
Bagging
Use a clockwise mowing pattern. This
will give the best bagging performance,
leaving the least amount of clippings on
the lawn. For thick, heavy grass, an
optional high-lift bagging blade may be
purchased from an authorized servicing
Honda dealer.

THE IMPORTANCE OF PROPER MAINTENANCE
Proper maintenance is essential for safe, economical, and trouble-free
operation. It will also help reduce air pollution.
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.
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.

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.
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.
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 the owner’s manual.

BLADE
1. Turn the fuel valve to OFF
(page 8). Disconnect the spark
plug cap from the spark plug
(page 35).
2. Tilt the mower to the right, so
the carburetor side is up. This
will help to prevent fuel leakage
and hard starting.
3. Inspect the blade [1] for wear
and damage.
A dull blade can be sharpened, but a blade that is worn out, bent,
cracked, or otherwise damaged must be replaced. A worn or damaged
blade can break, causing blade pieces to be thrown from the mower.
When a blade needs sharpening or replacement take the lawn mower
to an authorized Honda servicing dealer. Or, if you have a torque
wrench, you can remove and install the blade(s) yourself (page 30).
Check that the blade bolts are tight (page 30).
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(s) regularly. Do not operate
the mower with a worn or damaged blade.

stopped. If the engine has been running, allow it to cool first.
To refuel, remove the fuel tank cap [1], and fill the tank with gasoline to
the bottom of the filler neck [2]. Refuel carefully to avoid spilling fuel.
Do not overfill. There should be no fuel in the filler neck. 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.
Move at least 10 feet (3 meters) away
from the fueling source and site before starting the engine.
NOTICE
Fuel can damage paint and plastic. Be careful not to spill fuel when
filling your fuel tank. Damage caused by spilled fuel is not covered by
the Distributor’s Limited Warranty.
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

Fuel Recommendations
Use unleaded gasoline with a pump octane rating of 86 or higher.
These engines are 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.
This is considered misuse, and the Distributor’s Limited Warranty does
not cover parts damaged by misuse.

STORAGE
STORAGE PREPARATION
Proper storage preparation is essential for keeping your lawn mower
trouble-free 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
filter 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.

STORAGE
E 41
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 neglectful storage
preparation.
You can extend fuel storage life by adding a fuel 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.

Draining the Fuel Tank and Carburetor
1. Remove the carburetor drain bolt [1] with a 10 mm wrench, and
drain the carburetor bowl fuel into an approved container.
2. Turn the fuel valve ON (page 8).
This will allow fuel in the fuel tank
to drain through the carburetor
bowl. After the fuel is completely
drained, reinstall the drain bolt.
Engine Oil
Change the engine oil (page 33).
Engine Cylinder
Remove the spark plug (page 35). 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
[2]. Press each side of the lower
handlebar outward to release the
locating pins, then swing the handlebar
forward. Don’t allow the cables to be
bent or pinched.
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.
• Wipe up spills immediately.

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 (page 42).
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
(page 11).
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.

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 [1] to OFF [2] (page 20). This will prevent carburetor
flooding and reduce the possibility of fuel leakage.
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 42).
Put the front wheels in the LOCK position to decrease mower
movement while in transit (page 9).

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

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 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 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 the Distributor’s Limited Warranty.

Emission Control System
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 uses lean carburetor settings and other systems to reduce the
emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.
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
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.
Maintenance
Follow the maintenance schedule on page 28. Remember that this
schedule is based on the assumption that your machine will be used
for its designed purpose. Sustained high-load operation will require
more frequent service.
