Add Engine Oil
The mower is shipped
WITHOUT OIL in the engine.
Remove the oil filler cap/dipstick
and add the entire contents of
the included bottle of oil into the
oil filler opening.
BEFORE EACH OPERATION
Your safety is your responsibility. A little time spent in preparation will
significantly reduce your risk of injury.
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.
All Honda engines are run at the
factory prior to packaging. Most
of the oil is removed prior to
shipment; however, some oil
remains in the engine. The
amount of oil left in the engine varies.
Check Your Mower
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.
If you don’t use the supplied oil, add enough SAE 10W-30 API service
category SJ or later oil to bring the oil level between the upper and
lower limit marks on the dipstick—without screwing the dipstick in
Do not overfill the engine with oil. If the engine is overfilled, the
excess oil may get transferred to the air cleaner housing and air filter.
An indication of overfilling is white or blue smoke coming from the
muffler when the engine is running.
WARNING
Improperly maintaining this lawn mower, or failing to correct a
problem before operation, could cause a significant
malfunction.
After filling the engine with oil, screw the filler/cap dipstick in and
remove the hang tag near the recoil starter grip that says “The engine
has no oil.”
Some malfunctions can seriously hurt or kill you.
Always perform a pre-operation inspection before each
operation, and correct any problem.
Assemble the Grass Bag
• Make sure the lawn mower is on a level surface.
1. Install the assembled frame into the fabric grass bag, keeping the
grass bag handle exposed.
• Look around and underneath the lawn mower for signs of oil or
gasoline leaks.
2. Secure the seven plastic clips to attach the bag to the frame.
• Look for signs of damage.

before operating the lawn mower.
PLASTIC CLIP (7)
BAG FRAME
Anything that can be picked up by the blades and thrown is a potential
hazard to you and others. Look for things like stones, sticks, nails, and
wire, and remove them from the lawn area.
Please Register Your Mower
People and animals near the lawn 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 pets and people, especially children. Their
safety is your responsibility. Use extra care when approaching blind
corners, shrubs, trees, or other objects that may block your view of a
child.
Please take a few minutes and register your purchase with Honda.

REAR SHIELD
Grass Bag
A lawn mower works like a vacuum cleaner; it blows air through the
bag fabric, 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% filled.
Also, the bag is easier to empty when it is not packed full.
You can leave the grass bag on the mower during mowing, even
when full mulching is selected.
To minimize dust and fine particles from passing through the grass
bag fabric, it is best to mow grass in the morning when the grass is
damp.

Cutting Height Adjustment
There are two cutting height adjustment levers found on the left-hand
side of the lawn mower. The lever on the left front wheel adjusts the
height of both front wheels, and the lever on the left rear wheel adjusts
the height for both rear wheels. Both levers can be adjusted to one of
seven settings. The actual height of cut grass will vary with lawn and
soil conditions.
4. Screw in the filler cap/dipstick securely.
Add Fuel
This engine is certified to operate on regular gasoline with a pump
octane rating of 86 or higher.
Be sure the engine is not running when adjusting the cutting height.
Never use stale or contaminated gasoline or an oil/gasoline mixture.
Avoid getting dirt or water in the fuel tank.
Move the front and rear adjustment levers to the same position,
forward for tall grass and rearward for short grass.
To adjust the cutting height, move the rear cutting height adjustment
lever first. Grasp the handlebar and lift the mower up slightly, and then
pull the adjustment lever toward the wheel and move it into the
desired height. Adjust the front cutting height adjustment lever to
match the rear height setting.
You may use regular unleaded gasoline containing no more than 10%
ethanol (E10) or 5% methanol by volume. In addition, methanol must
contain cosolvents and corrosion inhibitors.

NOTICE
Clear Mowing Area
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
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 blades over gravel.
NOTICE
OPERATION
Striking objects with the spinning blades can cause severe engine
damage, which is not covered by the DISTRIBUTOR’S LIMITED
WARRANTY.
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.
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.
WARNING
Refuel With Care
Exhaust contains poisonous carbon monoxide gas that can
build up to dangerous levels in closed areas.
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.
Breathing carbon monoxide can cause unconsciousness or
death.
Never run the lawn mower in a closed, or even partially closed
area where people may be present.
Never fill containers inside a vehicle or on a truck or trailer bed with a
plastic liner. Always place containers on the ground away from your
vehicle before filling. Remove gas powered equipment from the truck
or trailer and refuel it on the ground. If this is not possible, then refuel
such equipment with a portable container, rather than from a gasoline
dispenser nozzle.
Safe Mowing Practices
Most injuries and property damage with walk-behind mowers can be
prevented if you follow all instructions in this manual and on the
mower. The most common hazards are discussed below, along with
the best way to protect yourself and others.
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.
Stop the Engine When Not Mowing
If you need to leave the mower for any reason, even just to inspect the
lawn ahead, always stop the engine by releasing the blade control
lever.
7
Continue to hold the lever fully against the handlebar. This will keep
the engine and blades rotating smoothly and prevent premature wear
to the flywheel brake system.
Avoid Slopes
Avoid steep slopes of more than 20°.
Mow across slopes, not up and down.
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.
Never operate the mower in wet grass.
Release the blade control lever to stop the engine and stop blade
rotation whenever you need to leave the mower.
Smart Drive Control
To prevent thumb fatigue, hold
the Smart Drive control as shown.
With the engine running
and the blades rotating,
slowly push the Smart
Drive control to propel the
mower forward.
NOTICE
Mowing on steep slopes can starve the
engine of oil, causing engine damage
that is not covered by the
Ground speed will increase
as more pressure is applied
to the Smart Drive control.
DISTRIBUTOR’S LIMITED
WARRANTY.
After maximum ground speed is obtained, applying additional
pressure will not further increase ground speed. Apply only enough
pressure to achieve the desired speed.
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. Do not mow near drop offs, ditches,
or embankments. You could lose your footing or balance.
Release the Smart Drive control to disengage the drive when mowing
around trees and other obstacles. Push the mower around obstacles
for better directional control.
If stuck, do not kick or shove the mower with your foot. Use the
handlebar to control the mower.
Ground speed varies with terrain, grass height, slope, and grass bag
weight. Moving the Smart Drive control allows you to maintain the
desired ground speed under constantly changing mowing conditions.
Avoid Obstacles
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. Never direct discharged
material toward anyone. Avoid discharging material against a wall or
obstruction. Material may ricochet back toward the operator. The best
way to prevent potential injury from thrown objects is to release the
blade control lever to stop the blades before reaching areas with
gravel, loose stones, or landscaping material.
Release the Smart Drive control to disengage (stop) the rear wheels.
Adjusting the Smart Drive Control
The Smart Drive control can be
adjusted up or down into any one
of five positions for operator
comfort.
Be careful when mowing over obstacles that stick up above the
surface of the lawn such as sprinkler heads, paving, edging, raised
tree roots, etc.
Do not attempt to adjust the

position of the Smart Drive
control while the mower is in
motion.
If the blade hits something, or if the mower starts to vibrate, stop the
engine immediately, disconnect the spark plug cap, and check for
crankshaft, and/or break the mower deck or other components.
Vibration usually indicates serious trouble.
Slide the multi-position adjuster to the left to unlock the control, move
the Smart Drive control up or down into the most comfortable position,
and then release the multi-position adjuster and allow it to engage.
Starting the Engine
WARNING
The blades turn when you start the
engine. Start the engine in a clear or
mowed area where the blades can
turn freely.
A worn, cracked, or damaged blade can break, and pieces of
the damaged blade can become dangerous projectiles.

Fallen Leaves
Stopping the Engine
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, adjust the front cutting height
adjustment lever so the front of the mower deck is one or two settings
higher than the rear.
1. Release the blade control lever to stop the engine.
2. When you finish mowing, turn the fuel valve OFF.
3. If your mower will not be used for 3 to 4 weeks, we recommend
running the engine’s carburetor out of fuel. You can do this by
leaving the fuel valve OFF, restarting the engine and running it
until the engine stops. See “AVOIDING FUEL-RELATED
a month or more.
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.
Mowing Tips
When to Mow
Clear a clogged deck with a stick, not your hands.
Most grasses should be mowed when they have grown ½ to 1 in
(12 ~ 25 mm) 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.
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 provide the best results.
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.
Mulching
Use a counterclockwise mowing
pattern. If the lawn has an
irregular shape, or many
obstacles, divide it into sections
where you can use
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.
counterclockwise patterns.
Cutting grass that is too tall or mowing the lawn too quickly can clog
the mower deck with grass and may cause the engine to stall. If your
grass gets too tall, cut it once at the highest cutting height setting
using a slow ground speed, then mow again in 2 or 3 days. Don’t take
off more than one third of the total grass height in any one mowing, or
brown patches may develop. Cutting height adjustment is explained
MULCHING PATTERN
Cutting Width
Bagging
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.
Use a clockwise mowing pattern.
This will give the best bagging
performance, leaving the least
amount of clippings on the lawn.
Blade Speed
The blades must spin very fast to cut properly. If engine speed drops,
it could mean the engine is being overloaded by the blades trying to
cut too much grass. Mow a narrower swath, move the mower slower,
use the rear 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 blades don’t cut cleanly
anymore, have them sharpened or replaced.
BAGGING PATTERN
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.

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.
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.
– Burns from hot parts.
Let the engine and exhaust system cool before touching.
The maintenance schedule applies to normal operating conditions. If
you operate your mower under severe conditions, such as sustained
high load, high temperature, or unusually wet or dusty conditions,
consult your servicing dealer for recommendations applicable to your
individual needs and use.
– 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, Honda Genuine parts or

Air Filter
To reduce the chance of scratching the side of the mower deck or
wheels when tipping, place a piece of cardboard or drop cloth on the
ground. The use of a commercially available siphon pump will save
time and make the oil change easier.
Clean the air filter after the first 25 hours of use. Thereafter, clean the
filter every 6 months or 50 hours of use. Clean the filter more often
when used in dusty areas. Replace the filter every 2 years or 150
hours of use.

A properly maintained air filter will help prevent dirt from entering your
engine. Dirt entering the carburetor can be drawn into small passages
in the carburetor and cause premature engine wear. These small
passages can become blocked, causing starting or running problems.

Cleaning
TRANSPORTING
Mower Deck
Allow the engine to cool before cleaning or washing.
If the engine has been running, allow it to cool before loading the
mower on the transport vehicle. A hot engine and exhaust system can
burn you and can ignite some materials.
Before cleaning or washing the underside of the mower deck, stop the
engine and turn the fuel valve to the OFF position. Rest the mower on
its right side, so the fuel cap 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 blades.
Turn the fuel valve to the OFF position. This will prevent carburetor
flooding and reduce the possibility of fuel leakage.
If installed, remove the grass bag.
Remove any grass clippings from the underside of the mower deck,
paying attention to the areas surrounding the Clip Director shutter
lever and housing.
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.
Be careful to avoid getting water into controls and cables, or
anywhere near the engine air cleaner or muffler opening.
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.
Engine
Allow the engine to cool before washing.
Wash the engine by hand, and be careful to prevent water from
entering the air cleaner and exhaust opening.
STORAGE
NOTICE
Using a garden hose or pressure washing equipment can force water
into the air filter. Water in the air cleaner will soak the paper element
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 before washing.
Proper storage preparation is essential for keeping your lawn mower
trouble free and looking good. To help keep rust and corrosion from
impairing your lawn mower’s function and appearance, and to make
the engine easier to start after storage, follow the instructions
described in this section to:
Grass Bag
• Drain or treat the fuel
• Change the oil and coat the engine cylinder
• Clean the mower, engine, and grass bag
• Choose a storage location
Remove the bag from the mower, and wash it with a garden hose or
pressure washer. Allow the bag to dry completely before storage.
Drying
After washing the lawn mower, wipe dry all accessible surfaces.
Fuel
Place the mower with its wheels on a level surface. Start the engine
outdoors and let it run until it reaches normal operating temperature to
evaporate any water remaining on the engine.
recommended procedures to avoid fuel related problems.
cover fuel system damage or engine performance problems resulting
from neglected storage preparation.
Stop the engine and allow it to cool.
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.
Oil
Storage Location
Add oil in the engine cylinder to prevent rust.
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 dry 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.
15
Make sure the fuel valve is in the OFF position to reduce the
possibility of fuel leakage.
Loss of Power
Possible Cause
Correction

Clean or replace the air filter
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.

Honda utilizes appropriate air/fuel ratios and other emissions control
systems to reduce the emissions of carbon monoxide, oxides of
nitrogen, and hydrocarbons. Additionally, Honda fuel systems utilize
components and control technologies to reduce evaporative
emissions.
TECHNICAL INFORMATION
Serial Number Locations
U.S. and California Clean Air Acts
U.S. EPA and California require all manufacturers to furnish written
instructions describing the operation and maintenance of emissions
control systems.
The following instructions and procedures must be followed in order to
keep the emissions from your Honda engine within the emissions
standards.
Tampering and Altering
FRAME SERIAL NUMBER
NOTICE
Tampering is a violation of federal and California law.
Tampering with or altering the emissions control system may increase
emissions beyond the legal limit. Among those acts that constitute
tampering are:
ENGINE
SERIAL NUMBER
• Removal or alteration of any part of the intake, fuel, or exhaust
systems.
• Altering or defeating the speed-adjusting mechanism to cause the
engine to operate outside its design parameters.
There are two serial numbers, one for the engine and one for the
mower frame. Record the engine and frame serial numbers in the
space below. You will need these serial numbers when ordering parts
and when making technical or warranty inquiries.
Problems That May Affect Emissions
Engine serial number: _________________________________
Frame serial number: __________________________________
Date of purchase: _____________________________________
High Altitude Operation
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, backfiring under load, or afterburning
• Black exhaust smoke or high fuel consumption
At high altitudes, 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.
Replacement Parts
The emissions control systems on your new Honda engine were
designed, built, and certified to conform with EPA and California
emissions regulations. We recommend the use of Honda Genuine
parts whenever you have maintenance done. These original-design
replacement parts are manufactured to the same standards as the
original parts, so you can be confident of their performance. Honda
cannot deny coverage under the emission warranty solely for the use
of non-Honda replacement parts or service performed at a location
other than an authorized Honda dealership; you may use comparable
EPA certified parts, and have service performed at non-Honda
locations. However, the use of replacement parts that are not of the
original design and quality may impair the effectiveness of your
emissions control system.
High altitude performance can be improved by specific modifications
to the carburetor. If you always operate your lawn 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.
A manufacturer of an aftermarket part assumes the responsibility that
the part will not adversely affect emissions 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 emissions
regulations.
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.
Maintenance
As the power equipment engine owner, you are responsible for
completing all required maintenance listed in your owner's manual.
Honda recommends that you retain all receipts covering maintenance
on your power equipment engine, but Honda cannot deny warranty
coverage solely for the lack of receipts or for your failure to ensure
that all scheduled maintenance has been completed.
Emission Control System
Source of Emissions
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.
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.

AVOIDING FUEL-RELATED PROBLEMS
When maintained properly, your Honda lawn mower should provide years of trouble-free operation. This includes the fuel system. However,
gasoline can quickly deteriorate, causing starting or running problems and, in some cases, damage to the fuel system. Most fuel-related
problems can be avoided by following the precautions listed below. Fuel system damage and engine performance problems resulting from
Follow These Precautions to Prevent Most Fuel-Related Problems
During the Normal Mowing Season
Reason
Do not use gasoline containing more than 10% ethanol.
A high level of ethanol in gasoline attracts water and can corrode or
damage the fuel system and cause performance problems.
Store gasoline in a clean, plastic, sealed container approved for fuel
storage.
A clean plastic container will prevent rust and metallic contaminants
from entering the fuel system.
Store your fuel supply container away from direct sunlight; if the
container has a vent, keep it closed.
Gasoline will deteriorate faster when exposed to air and sunlight.
Purchase only enough gasoline to last for 30 to 60 days.
Gasoline deteriorates with age, so try to avoid storing it for long
periods, especially in summer heat.
If you purchase enough gasoline to last for more than 60 days, add
a fuel stabilizer to your storage tank when you fill it.
Fuel stabilizer will extend the shelf life of gasoline, but it will not
reconstitute stale fuel.
When you finish mowing, turn the fuel valve OFF and fill the
mower’s fuel tank.
If the fuel tank is only partially filled, air in the tank will promote fuel
deterioration.
3 to 4 Weeks Before Next Use
Reason
Turn the fuel valve OFF and fill the mower’s fuel tank.
If the fuel tank is only partially filled, air in the tank will promote fuel
deterioration.
With the fuel valve off, start the engine and let it run until it runs out
of gas. Running time should be approximately 3 minutes.
The small amount of gasoline in your lawn mower’s carburetor will
deteriorate faster than the fuel in the fuel tank due to its small
volume and heat from the engine.
1 to 3 Months Before Next Use
Reason
If you did not add fuel stabilizer to your fuel storage tank when you
filled it up, fill your mower’s fuel tank with fresh gasoline.
If the fuel tank is only partially filled, air in the tank will promote fuel
deterioration.
Add fuel stabilizer to the mower tank according to the stabilizer
manufacturer’s instructions.
Fuel stabilizer will extend the life of gasoline, but it will not
reconstitute stale gasoline.
Run the engine outdoors for 10 minutes.
To make sure treated gasoline has replaced untreated gasoline
throughout the fuel system.
Stop the engine and turn the fuel valve OFF. Restart the engine and
let it run until it runs out of gasoline. Running time should be
approximately 3 minutes.
The small amount of gasoline in your lawn mower’s carburetor will
deteriorate faster than the fuel in the fuel tank due to its small
volume and heat from the engine.
More Than 3 Months Before Next Use
Reason
Start the engine and let it run long enough to empty all the gasoline
from the entire fuel system, including the fuel tank. Do not allow
gasoline to remain in your lawn mower for more than 3 months of
inactivity.
All fuel stabilizers have a shelf life. It is good practice to empty the
fuel system for long-term inactivity.
We recommend Pro Honda Fuel Stabilizer that has an improved formulation with added corrosion protection (page 20).

EMISSION SYSTEM WARRANTY
Your new Honda Power Equipment engine complies with the U.S. EPA, and
Honda cannot deny coverage under the emission warranty solely for use of
non-Honda replacement parts or service performed at a location other than an
authorized Honda dealership; however, use of a part that is not functionally
identical to the original equipment part in any respect that may in any way
affect emissions (including durability) could result in denial of coverage. If such
a non-Honda 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.
State of California (models certified for sale in California only) emission
regulations. American Honda Motor Co., Inc. provides the emission warranty
coverage for engines in the United States and its territories. In the remainder
of this Emission Control System Warranty, American Honda Motor Co., Inc.,
will be referred to as Honda.
YOUR WARRANTY RIGHTS AND OBLIGATIONS:
CALIFORNIA
The California Air Resources Board and Honda are pleased to explain the
emission control system warranty on your 2019 and later Honda Power
Equipment engine. In California, new spark-ignited small off-road equipment
engines must be designed, built, and equipped to meet the state's stringent
anti-smog standards. Specific Honda products that do not meet the California
emissions regulations can be identified by a “Not for sale in California” decal.
TO OBTAIN WARRANTY SERVICE:
You must, at your own expense, take your Honda Power Equipment engine or
the product on which it is installed, along with your sales registration card or
other proof of original purchase date, to any Honda Power Equipment dealer
who is authorized by Honda to sell and service that Honda product during their
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 emission 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, contact the Honda office in your region. Refer to adjacent
column for contact information.
OTHER STATES AND U.S. TERRITORIES
In other areas of the United States your engine must be designed, built, and
equipped to meet the U.S. EPA emission standards for spark-ignited engines
at or below 19 kilowatts.
ALL OF THE UNITED STATES
Honda 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, Honda 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 (see the
adjacent column for additional covered parts).
EXCLUSIONS:
Failures other than those resulting from defects in material or workmanship are
not covered by this warranty. This warranty does not extend to emission control
systems or parts that are affected or damaged by owner abuse, neglect,
improper maintenance, misuse, misfueling, improper storage, collision, the
incorporation of, or use of, unsuitable attachments, or the unauthorized
alteration of any part.
OWNER'S WARRANTY RESPONSIBILITY:
This warranty does not cover replacement of expendable maintenance items
made in connection with required maintenance service after the item’s first
scheduled replacement as listed in the maintenance section of the product
owner’s manual, such as: spark plugs and filters.
As the power equipment engine owner, you are responsible for completing all
required maintenance listed in your owner's manual. Honda recommends that
you retain all receipts covering maintenance on your power equipment engine,
but Honda cannot deny warranty coverage solely for the lack of receipts or for
your failure to ensure that all scheduled maintenance has been completed.
DISCLAIMER OF CONSEQUENTIAL DAMAGE AND LIMITATION
OF IMPLIED WARRANTIES:
As the power equipment engine owner, you should however be aware Honda
may deny you warranty coverage if your power equipment engine or a part has
failed due to abuse, neglect, improper maintenance, or unapproved
modifications.
American Honda Motor Co., Inc. disclaims any responsibility for incidental or
consequential damages such as loss of time or the use of the power
equipment, or any commercial loss due to the failure of the equipment; and
any implied warranties are limited to the duration of this written warranty. This
warranty is applicable only where the California or U.S. EPA emission control
system warranty regulation is in effect.
You are responsible for presenting your power equipment engine to a Honda
Power Equipment dealer as soon as a problem exists. The emission related
warranty repairs should be completed in a reasonable amount of time, not to
exceed 30 days.
If you have any questions regarding your emission warranty rights and
responsibilities, you should contact the Honda office in your region:
