BEFORE OPERATION CHECKS
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.
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
1. Look around and underneath the engine for signs of oil or
gasoline leaks.
2. Remove any excessive dirt or debris, especially around the
muffler and recoil starter.
3. Look for signs of damage.
4. Check that all shields and covers are in place, and all nuts,
bolts, and screws are tightened.
Check the Engine
1. Check the fuel level (see page 8). Starting with a full tank will
help to eliminate or reduce operating interruptions for refueling.
2. Check the engine oil level (see page 9). Running the engine with
a low oil level can cause engine damage.
The Oil Alert system (applicable types) will automatically stop
the engine before the oil level falls below safe limits. However,
to avoid the inconvenience of an unexpected shutdown, always
check the engine oil level before startup.
3. Check the reduction case oil level on applicable types (see page
9). Oil is essential to reduction case operation and long life.
4. Check the air filter element (see page 10). A dirty air filter
element will restrict air flow to the carburetor, reducing engine
performance.
5. Check the equipment powered by this engine.
Review the instructions provided with the equipment powered
by this engine for any precautions and procedures that should
be followed before engine startup.
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.
OPERATION
SAFE OPERATING PRECAUTIONS
Before operating the engine for the first time, please review the
SAFETY INFORMATION section on page 2 and the BEFORE
OPERATION CHECKS on page 4.
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.
Review the instructions provided with the equipment powered by
this engine for any safety precautions that should be observed with
engine startup, shutdown, or operation.
Do not operate the engine on slopes greater than 20° (36%).
STARTING THE ENGINE
1. Move the fuel valve lever to the ON position.
2. To start a cold engine, move the choke lever to the CLOSED
position.
To restart a warm engine, leave the choke lever in the OPEN
position.

SERVICING YOUR ENGINE
THE IMPORTANCE OF MAINTENANCE
Good maintenance is essential for safe, economical, and
trouble-free operation. It will also help reduce pollution.
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 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.
SAFETY PRECAUTIONS
Make sure the engine is off before you begin any maintenance or
repairs. To prevent accidental startup, disconnect the spark plug
cap. This will eliminate several potential hazards:
Carbon monoxide poisoning from engine exhaust.
Operate outside, away from open windows or doors.
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 non-flammable 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
engine best and is fully equipped to maintain and repair it.
To ensure the best quality and reliability, use only new Honda
Genuine parts or their equivalents for repair and replacement.
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.
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.

Cleaning
Dual-Filter Element Types
1. Remove the wing nut from the air
cleaner cover, and remove the
cover.
2. Remove the wing nut from the air
filter, and remove the filter.
3. Remove the foam filter element
from the paper filter element.
4. Inspect both air filter elements,
and replace them if they are
damaged. Always replace the
paper air filter element at the
scheduled interval (see page 7).
5. Clean the air filter elements if they are to be reused.
Paper filter element: Tap the filter element several times on a
hard surface to remove dirt, or blow compressed air [not
exceeding 207 kPa (2.1 kgf/cm
2
, 30 psi)] through the filter
element from the inside. Never try to brush off dirt; brushing
will force dirt into the fibers.
Foam filter element: Clean in warm soapy water, rinse, and
allow to dry thoroughly. Or clean in non-flammable solvent and
allow to dry. Dip the filter element in clean engine oil, and then
squeeze out all excess oil. The engine will smoke when started
if too much oil is left in the foam.
6. CYCLONE TYPE ONLY: Remove the three pan-head screws
from the precleaner cap, then remove the cyclone housing and
air guide. Wash the parts with water, dry them thoroughly, and
reassemble them.
Be sure to install the air guide as shown in the illustration.
Install the cyclone housing so the air intake tab fits into the
groove in the precleaner cap.

SPARK ARRESTER (applicable types)
In Europe and other countries where the machinery directive
2006/42/EC is enforced, this cleaning should be done by your
servicing dealer.
The spark arrester may be standard or an optional part, depending
on the engine type. In some areas, it is illegal to operate an engine
without a spark arrester. Check local laws and regulations. A spark
arrester is available from authorized Honda servicing dealers.
The spark arrester must be serviced every 100 hours to keep it
functioning as designed.
If the engine has been running, the muffler will be hot. Allow it to
cool before servicing the spark arrester.
Spark Arrester Removal
1. Remove the air cleaner (see page 11).
2. Remove the two 4 mm screws from the exhaust deflector, and
then remove the deflector and muffler guide (applicable types).
3. Remove the four 5 mm screws from the muffler protector and
remove the muffler protector.
4. Remove the 4 mm screw from the spark arrester, and remove
the spark arrester from the muffler.
Spark Arrester Cleaning & Inspection

HELPFUL TIPS & SUGGESTIONS
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.
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.
1. Add gasoline stabilizer following the manufacturer’s
instructions.
2. After adding a gasoline stabilizer, run the engine outdoors for
10 minutes to be sure that treated gasoline has replaced the
untreated gasoline in the carburetor.
3. Stop the engine.

14 ENGLISH
Draining the Fuel Tank and Carburetor
1. Move the fuel valve lever to the OFF position (see page 6).
2. Place an approved gasoline container below the carburetor, and
use a funnel to avoid spilling fuel.
3. Loosen the carburetor drain bolt. Remove the sediment cup and
O-ring, then move the fuel valve lever to the ON position (see
page 4).
4. After all the fuel has drained into the container, reinstall the
sediment cup and a new O-ring. Tighten the carburetor drain
bolt and sediment cup securely.
Engine Oil
1. Change the engine oil (see page 9).
2. Remove the spark plug (see page 12).
3. Pour a teaspoon 5–10 cm
3
(5–10 cc) of clean engine oil into
the cylinder.
4. Pull the starter rope several times to distribute the oil in the
cylinder.
5. Reinstall the spark plug.
6. Pull the starter rope slowly until resistance is felt and the notch
on the starter pulley aligns with the hole at the top of the recoil
starter cover. This will close the valves so moisture cannot
enter the engine cylinder. Return the starter rope gently.
7. Electric starter type: Remove the battery and store it in a cool,
dry place. Recharge it once a month.
8. Cover the engine to keep out dust.
Gasoline is highly flammable and explosive, and 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 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
spark-producing 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.
If equipped with a battery for electric starter types, recharge the
battery once a month while the engine is in storage.
This will help to extend the service life of the battery.
Removal from Storage
Check your engine as described in the BEFORE OPERATION
CHECKS section of this manual (see page 4).
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.
Keep the engine level when transporting to reduce the possibility of
fuel leakage. Move the fuel valve lever to the OFF position (see
page 6).

Carburetor Modifications 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 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.
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 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.
Replacement Parts
The emission control systems on your Honda engine were
designed, built, and certified to conform with EPA, California and
Canadian 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 7. 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.
