BEFORE OPERATION CHECKS OPERATION
IS YOUR ENGINE READY TO GO?
For your safety, to ensure compliance with environmental
regulations, and to maximize the service life of your equipment, it
is very important to take a few moments before you operate the
engine 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 engine.
Improperly maintaining this engine, or failure to
correct a problem before operation, can cause a
malfunction in which you can be seriously hurt or
killed.
Always perform a pre-operation inspection before
each operation, and correct any problem.
Before beginning your pre-operation checks, be sure the engine is
level and the engine switch is in the OFF position.
Always check the following items before you start the engine:
Check the General Condition of the Engine
Look around and underneath the engine for signs of oil or
1.
gasoline leaks.
Remove any excessive dirt or debris, especially around the
2.
muffler and recoil starter.
Look for signs of damage.
3.
Check that all shields and covers are in place, and all nuts, bolts,
4.
and screws are tightened.
SAFE OPERATING PRECAUTIONS
Before operating the engine for the first time, please review the
SAFETY INFORMATION
OPERATION CHECKS
section on page and the
2
on this page.
BEFORE
For your safety, do not operate the engine in an enclosed area
such as a garage. Your engine’s exhaust contains poisonous
carbon monoxide gas that can collect rapidly in an enclosed area
and cause illness or death.

SERVICING YOUR ENGINE
THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical, and troublefree operation. It will also help reduce pollution.
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 engine, 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 engine under severe conditions, such as
sustained high-load or high-temperature operation, or use in
unusually wet or dusty conditions, consult your Honda 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.
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.

STORING YOUR ENGINE
Storage Preparation
Proper storage preparation is essential for keeping your engine
trouble-free and looking good. The following steps will help to
keep rust and corrosion from impairing your engine’s function and
appearance, and will make the engine easier to start when you use
it again.
Cleaning
If the engine has been running, allow it to cool for at least half an
hour before cleaning. Clean all exterior surfaces, touch up any
damaged paint, and coat other areas that may rust with a light film
of oil.
Using a garden hose or pressure washing equipment can force
water into the air cleaner or muffler opening. Water in the air
cleaner will soak the air filter, and water that passes through the
air filter or muffler can enter the cylinder, causing damage.
Fuel
Depending on the region where you operate your equipment, fuel
formulations may deteriorate and oxidize rapidly. Fuel
deterioration and oxidation can occur in as little as 30 days and
may cause damage to the carburetor and/or fuel system. Please
check with your servicing dealer for local storage
recommendations.

FUSE COVER
Never use a fuse with different rating from that specified.
Serious damage to the electrical system or fire may result.

5.
Install the fuse socket to the stay.
Gasoline will oxidize and deteriorate in storage. Deteriorated
gasoline will cause hard starting, and it leaves gum deposits that
clog the fuel system. If the gasoline in your engine 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.
Fuel system damage or engine performance problems resulting
from neglected storage preparation are not covered under the
Distributor’s Limited Warranty
.
You can extend fuel storage life by adding a gasoline stabilizer
that is formulated for that purpose, or you can avoid fuel
deterioration problems by draining the fuel tank and carburetor.
Adding a Gasoline Stabilizer to Extend Fuel Storage Life
When adding a gasoline stabilizer, fill the fuel tank with fresh
gasoline. If only partially filled, air in the tank will promote fuel
deterioration during storage. If you keep a container of gasoline
for refueling, be sure that it contains only fresh gasoline.
Add gasoline stabilizer following the manufacturer’s instructions.
1.
2.
After adding a gasoline stabilizer, run the engine outdoors for 10
minutes to be sure that treated gasoline has replaced the
untreated gasoline in the carburetor.
Stop the engine.

Storage Precautions
If your engine 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 sparkproducing electric motor, or where power tools are operated.
If possible, avoid storage areas with high humidity, because that
promotes rust and corrosion.
Keep the engine level in storage. Tilting can cause fuel or oil
leakage.
With the engine and exhaust system cool, cover the engine 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 engine,
promoting rust and corrosion.
Stop the engine and keep heat, sparks, and flame
away.
Handle fuel only outdoors.
Wipe up spills immediately.

Removal from Storage
Check your engine as described in the
CHECKS
section of this manual (see page ).
BEFORE OPERATION
5
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 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
If the engine has been running, allow it to cool for at least 15
minutes before loading the engine-powered equipment on the
transport vehicle. A hot engine and exhaust system can burn you
and can ignite some materials.
Turn the fuel valve lever to the OFF position.
Keep the engine level when transporting to reduce the possibility
of fuel leakage.

Carburetor Modifications for High Altitude Operation Emission Control System Information
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 engine
at altitudes above 1,500 meters (5,000 feet), 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 300 meter (1,000 foot) increase in
altitude. The effect of altitude on horsepower will be greater than
this if no carburetor modification is made.
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 1,500 meters (5,000 feet) 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.
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 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.
The U.S., California Clean Air Act, and Environment Canada
EPA, California, and Canadian 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.
ENGLISH

The emission control systems on your Honda engine were
designed, built, and certified to conform with EPA, California
(models certified for sale in California), and Canadian emission
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. 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 . Remember that this
6
schedule is based on the assumption that your machine will be
used for its designed purpose. Sustained high-load or hightemperature operation, or use in unusually wet or dusty conditions,
will require more frequent service.
Air Index
An Air Index Information label is applied to engines certified to an
emission durability time period in accordance with the
requirements of the California Air Resources Board.
The bar graph is intended to provide you, our customer, the ability
to compare the emissions performance of available engines. The
lower the Air Index, the less pollution.
The durability description is intended to provide you with
information relating to the engine’s emission durability period.
The descriptive term indicates the useful life period for the engine’s
emission control system. See your
Warranty
for additional information.
