SAFETY PRECAUTIONS
If the engine has run out of fuel, pull the choke rod to the CLOSED
position after refueling. If the engine has not run out of fuel, leave the
choke rod in the OPEN position.
• 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
engine 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.
1. Pull the starter grip lightly until you feel resistance, then pull briskly.
2. If the choke was pulled to the CLOSED position to start, push it to
the OPEN position as soon as the engine starts.
Stopping The Engine
Move the engine stop switch to the OFF position.
OIL ALERT® SYSTEM
The Oil Alert system is designed to prevent engine damage caused by
an insufficient amount of oil in the crankcase. Before the oil level in the
crankcase can fall below a safe limit, the Oil Alert system will
automatically stop the engine [the throttle lever (ignition switch lever)
will remain in a run position].
If the engine stops and will not restart, check the engine oil level
(page 5) before troubleshooting in other areas.

AIR CLEANER
SPARK PLUG
A dirty air cleaner will restrict air flow to the carburetor and cause poor
engine performance. Inspect the filter each time the engine is
operated. You will need to clean the filter more frequently if you
operate the engine in very dusty areas.
Recommended Spark Plug: NGK BPR6ES
NOTICE
NOTICE
Operating the engine without an air filter, or with a damaged filter, will
allow dirt to enter the engine, causing rapid engine wear. This type of
damage is not covered under the Distributor’s Limited Warranty (see
page 11).
Incorrect spark plugs can cause engine damage.
Inspection
1. Disconnect the cap from
the spark plug, and
remove any dirt from the
spark plug area.
The recommended spark plug is the correct heat range for normal
engine operating temperatures.
For good performance, the
spark plug must be properly
gapped and free of deposits.
1. Press the latch tabs on the top of the air cleaner cover, and remove
the cover.
2. Remove the foam element from the air cleaner cover.
2. Use the proper size spark
plug wrench to remove the
spark plug.
3. Remove the screen grid from the paper element.
4. Check both elements to be sure they are clean and in good
condition.
3. Inspect the spark plug. Replace it if
damaged, badly fouled, if the
sealing washer is in poor condition,
or if the electrode is worn.
5. Reinstall the screen grid over the paper element. Make sure that
the screen grid completely surrounds the paper pleats.
6. Reinstall the foam element in the air cleaner cover.
4. Measure the electrode gap with a
suitable gauge. The correct gap is
0.028 - 0.031 in (0.70 - 0.80 mm). If

1. Paper Element: Tap the paper element several times on a hard
surface to remove dirt, or blow compressed air [not exceeding 30
psi (207 kPa, 2.1 kg/cm²)] through the filter from the clean side that
faces the engine. Never try to brush off dirt. Brushing will force dirt
into the fibers.
2. Foam Element: Wash the element in a solution of household
detergent and warm water, then rinse thoroughly, or wash in
nonflammable or high flash point solvent. Allow the element to dry
thoroughly.
Soak the element in clean engine oil and squeeze out the excess
oil. The engine will smoke during initial start-up if too much oil is left
in the foam, or the oil could saturate the paper element making the
engine inoperable.
3. Wipe dirt from the air cleaner body and cover using a moist rag. Be
careful to prevent dirt from entering the air duct that leads to the
carburetor.

SPARK ARRESTER (optional equipment)
Fuel
In some areas, it is illegal to operate an engine without a USDA
(United States Department of Agriculture)-qualified spark arrester.
Check local laws and regulations. A USDA-qualified spark arrester is
available from an authorized Honda servicing dealer.
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 spark arrester must be serviced every 100 hours to keep it
functioning as designed.
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 problems may occur within a few
months, or even less if the gasoline was not fresh when you filled the
fuel tank.
If the engine has been running, the muffler will be hot. Allow it to cool
before servicing the spark arrester.
Spark Arrester Removal
MUFFLER
1. Remove the three 6 mm
bolts from the muffler

PROTECTOR
Fuel system damage or engine performance problems resulting from

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.

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.
NOTICE
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.
7
Storage Precautions
DRAINING THE FUEL TANK AND CARBURETOR
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.
 WARNING
Gasoline is highly flammable and explosive, and you can
be burned or seriously injured when handling fuel.
• Stop engine and keep heat, sparks, and flame away.
• Refuel only outdoors.
• Wipe up spills immediately.
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.
1. Use a siphon pump (commercially available) and siphon the fuel
out of the fuel tank into an approved gasoline container.
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.
2. Place an approved gasoline container below the carburetor, and
use a funnel to avoid spilling fuel.
3. Loosen the carburetor drain screw. and drain the carburetor into an
approved gasoline container. After draining is completed, tighten
the carburetor drain screw.
SIPHON PUMP
(COMMERCIALLY
AVAILABLE)
Removal From Storage
Check your engine as described in the BEFORE OPERATION
CHECKS section of this manual (see page 2).
FLOAT BOWL
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
DRAIN SCREW

TECHNICAL & CONSUMER INFORMATION
Oxygenated Fuels
Some conventional gasolines are being blended with alcohol or an
ether compound. These gasolines are collectively referred to as
oxygenated fuels. To meet clean air standards, some areas of the
United States and Canada use oxygenated fuels to help reduce
emissions.
TECHNICAL INFORMATION
Serial Number and Type Location
Record the engine serial
number and type in the
space below. You will
need this information
when ordering parts and
when making technical
or warranty inquiries.
If you use oxygenated fuel, be sure it is unleaded and meets the
minimum octane rating requirements.
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 the EPA approved percentages of oxygenates:
ETHANOL
— (ethyl or grain alcohol) 10% by volume
You may use gasoline containing up to 10% ethanol
by volume. Gasoline containing ethanol may be
marketed under the name Gasohol.
MTBE
— (methyl tertiary butyl ether) 15% by volume
You may use gasoline containing up to 15% MTBE
by volume.

GCACA– ___ ___ ___ ___ ___ ___ ___
___ ___ ___ ___
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.
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.
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 (see page 11).
High altitude performance can be improved by specific modifications to
the carburetor. If you always operate your trimmer 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.

Emission Control System Information
Air Index
Source of Emissions
An Air Index Information hang tag/label is applied to engines certified
to an emission durability time period in accordance with the
requirements of the California Air Resources Board.
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.
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.
Honda utilizes lean carburetor settings and other systems to reduce
the emissions of carbon monoxide, oxides of nitrogen, and
hydrocarbons.
The durability description is intended to provide you with information
relating the engine’s emission durability period. The descriptive term
indicates the useful life period for the engine’s emission control
system. See your Emission Control System Warranty (page 12) for
additional information.
The U.S. and California Clean Air Acts
EPA and California regulations require all manufacturers to furnish
written instructions describing the operation and maintenance of
emission control systems.
Descriptive Term
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
Applicable to Emissions Durability Period
Moderate
50 hours (0–65 cc)
125 hours (greater than 65 cc)
Intermediate

250 hours (greater than 65 cc)
Extended
300 hours (0–65 cc)
500 hours (greater than 65 cc)
The Air Index Information hang tag/label must remain on the engine
until it is sold. Remove the hang tag before operating the engine.
Tampering with or altering the emission control system may increase
emissions beyond the legal limit. Among those acts that constitute
tampering are:
Specifications
Length x Width x Height
• 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

The emission control systems on your Honda engine were designed,
built, and certified to conform with EPA and California emission
regulations. We recommend the use of genuine Honda parts
whenever you have maintenance done. These original-design
replacement parts are manufactured to the same standards as the
original parts, so you can be confident of their performance. The use of
replacement parts that are not of the original design and quality may
impair the effectiveness of your emission control system.
A manufacturer of an aftermarket part assumes the responsibility that
the part will not adversely affect emission performance. The
manufacturer or rebuilder of the part must certify that use of the part
will not result in a failure of the engine to comply with emission
regulations.
Maintenance
Follow the maintenance schedule on page 5. 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.

How do I check the oil level?
To check the oil level, stop the engine and make sure it is level. Remove the oil filler cap/dipstick and wipe it clean. Insert the dipstick into the oil filler neck but don't screw it in. Then remove it to check the oil level. If it's near or below the lower limit mark, add oil to the upper limit mark. Do not overfill.
What type of fuel should I use?
Use unleaded gasoline with a pump octane rating of 86 or higher. This engine is certified to operate on unleaded gasoline.
How often should I service the spark arrester?
The spark arrester should be serviced every 100 hours to ensure it is functioning correctly. Consult the manual for detailed instructions on cleaning and inspection.
