TRIMMER SAFETY
Keep the Trimmer Properly Maintained
IMPORTANT SAFETY INFORMATION
• The cutting attachment should be examined for looseness, cracks,
broken parts, or excessive wear. Tighten or replace as needed
before operating the trimmer.
The Honda HHT25S and HHT35S trimmer/brush cutters are designed
to cut grass, weeds, brush, and/or wood if equipped with an
appropriate cutting attachment. Other uses can result in injury to the
operator or damage to the trimmer and other property.
• Do not operate the trimmer without a debris shield properly
installed. Make sure you have the right shield installed for your
cutting attachment.
For more information, see page 20.
These Honda trimmers are intended for use by gardening
professionals. Never allow children to operate the trimmer.
ATTACHMENTS & MODIFICATIONS
Most injuries or property damage can be prevented if you follow all
instructions in this manual and on the trimmer. The most common
hazards are discussed below, along with the best way to protect
yourself and others.
Modifying your trimmer/brush cutter, or installing non-Honda
attachments, can make your trimmer unsafe. Before you make any
modifications or install any attachments, be sure to read the following
information.
Always Wear Eye Protection and Protective Clothing
Attachments
• The most frequent injuries associated with string trimmers are eye
injuries caused by thrown debris. Always wear safety glasses or
goggles that meet the ANSI Z87.1 rating whenever you use the
trimmer.
Your Honda trimmer servicing dealer has cutting attachments, debris
shields, barrier kits, and shoulder harnesses that have been designed
and approved for your trimmer and are covered by warranty. See
RECOMMENDED CUTTING ATTACHMENTS (page 18).
• The operator must wear hearing protectors when using this
trimmer. Hearing protectors will protect the operator's ears from
noise damage.
Non-Honda attachments are usually designed for universal
applications. Although aftermarket attachments may fit on your
trimmer, they may not meet factory specifications and could make
your trimmer unsafe.
• Wearing protective clothing also reduces the risk and severity of
injury from thrown debris or contact with the cutting attachment.
Wear the trimmer harness, gloves, a long-sleeved shirt, long pants,
and sturdy boots with nonslip soles.
See page 9 for more information.
Keep Away From Cutting Lines and Blades
• A spinning cutting blade can cut through your clothes and skin just
as easily as it cuts through grass and dirt. Keep all parts of your
body away from a spinning cutting attachment.
Modifications
Do not remove the debris shield or modify your trimmer in any way
that would alter its design or operation. This could make your trimmer
unsafe.
IMPORTANT MESSAGE TO EMPLOYERS
As an employer, you have special responsibilities to the people who
work for you.
• Even after the engine has stopped, the cutting attachment will spin
for several seconds. Do not touch it until it has stopped spinning, or
you may get cut.
Before you ask anyone to operate this trimmer/brush cutter, you need
to determine whether the operator is old enough, large enough, and
strong enough to safely handle and control the trimmer/brush cutter.
Turn the Engine Off When Not Trimming
If you decide he/she is, make sure the employee(s) read and
understand all instructions and warnings in this manual and on the
labels before operating the trimmer/brush cutter.
If you stop trimming or cutting for any reason, even to clean off the
cutting attachment, always shut off the engine.
Keep People Away From Your Working Area
To prevent injury to others, keep people at least 50 feet (15 meters)
away from the working area during operation.
Always Wear the Harness When Trimming
The harness keeps the trimmer away from your body, lowering your
chances of being cut by the trimmer’s blade or cutting line.
Allow adequate time for hands-on training by a qualified instructor,
and personally supervise practice sessions, until you feel sure the
employee is ready to operate the trimmer/brush cutter.
Also be sure employees wear proper clothing, eye and hearing
protection, and any other gear that may be required by local
ordinances or your insurance company.
Read This Manual Before Using the Trimmer
Remember, too, that you are responsible for keeping the
trimmer/brush cutter properly maintained and in safe operating
condition.
Read the manual before operating the trimmer. Understand how to
use all the controls and obey all warnings.
Your commitment to safety on the job can help prevent injuries and
result in longer and more productive years of service.
Clear the Working Area First
Objects thrown by the trimmer can cause serious injury. Before
operating the trimmer, carefully inspect the area and remove any
broken glass, pieces of wire, and other loose objects.

SAFETY LABEL LOCATIONS
ASSEMBLY
The labels shown here contain important safety information. Please
read them carefully. These labels are considered permanent parts of
your trimmer/brush cutter. If a label comes off or becomes hard to
read, contact an authorized Honda servicing dealer for a replacement.
After assembly and before operation, review the SAFE OPERATING
PRECAUTIONS on page 10.
LOOP HANDLE AND
U-TYPE HANDLE TYPES
IMPORTANCE OF PROPER ASSEMBLY
Proper assembly is essential to operator safety and the reliability of
the machine. Any error or oversight made by the person assembling
and servicing a machine can result in faulty operation, damage to the
machine, or injury to the operator.
B WARNING
Improper assembly can cause an unsafe condition that
can lead to serious injury or death.
Follow the procedures and precautions in the assembly
instructions carefully.
Some of the most important safety precautions are given below.
However, we cannot warn you of every conceivable hazard that can
arise in performing this assembly. Only you can decide whether or not
you should perform a given task.
B WARNING
Failure to properly follow instructions and precautions
can cause you to be seriously hurt or killed.
Follow the procedures and precautions in this manual
carefully.
IMPORTANT SAFETY PRECAUTIONS
• Make sure you have a clear understanding of all basic shop safety
practices and that you are wearing appropriate clothing and safety
equipment.
• Read the instructions before you begin and be sure you have the
tools and skills required to perform the tasks safely.
• Make sure the engine is off before you begin any maintenance or
repairs. This will help eliminate several potential hazards:
T
T
T
Carbon monoxide poisoning from engine exhaust. Be sure
there is adequate ventilation whenever you run 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 the
instruction tells you to do so. Even then, keep your hands,
fingers, and clothing away from moving parts. Do not run the
engine when any protective guard or shield is removed.
• To reduce the possibility of a fire or explosion, be careful when
working around gasoline. Use only a nonflammable solvent, not
gasoline, to clean parts. Keep all cigarettes, sparks, and flames
away from all fuel-related parts.

ARE YOU READY TO OPERATE THE TRIMMER?
Your safety is your responsibility. A little time spent in preparation will
significantly reduce your risk of injury.
IS YOUR TRIMMER 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 trimmer to check its

how to operate them.
Familiarize yourself with the trimmer and its operation before you
begin to use it. Know what to do in case of emergencies.
You must be alert and in good physical condition to operate the
trimmer. Do not operate the trimmer if you are tired, ill, or under the
influence of alcohol, medication, or any substance that might impair
your vision, dexterity, or judgment.

Improperly maintaining this trimmer, 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.
If you have any physical problem that may be aggravated by
strenuous work, consult your physician before operating the trimmer.
Wearing protective clothing will reduce your risk of injury. Do not wear
loose clothing, jewelry, short pants, sandals, or go barefoot. Secure
hair so it is above shoulder level.
Always wear safety glasses or goggles that comply with ANSI
standard Z87.1 to protect your eyes from thrown objects. Prescription
glasses may be worn under the safety glasses or goggles.
A helmet with a face shield is recommended for further protection.
However, safety glasses or goggles should always be worn under the
face shield. Do not rely on a face shield alone to protect your eyes.
Safety Inspection
• Look around the engine for signs of oil or gasoline leaks. Wipe up
any spills before starting the engine.
• Replace any damaged parts.
• Check that all fasteners are in place and secure. Tighten as
necessary.
Cutting Attachment Inspection
Wearing a dust mask will help to reduce the amount of pollen and dust
inhaled.
• Look for signs of damage to the cutting attachment (see page 21
and page 19). Replace any cutting attachment and parts that are
worn out, bent, cracked, chipped, or damaged in any way.
Hearing protectors will help to protect your ears from noise.
Earmuff-style hearing protectors can also protect your ears from
thrown objects.
• If using a metal blade, be sure it is sharp. A dull blade is more likely
to snag and thrust.
Wear gloves, a long-sleeved shirt, and long pants made of heavy
material. Clothing should fit closely but allow freedom of movement,
and should have no strings, straps, etc. that could catch on brush or
the trimmer. Keep clothing fastened.
Wear sturdy work boots with good toe protection and nonslip soles.
IS YOUR WORKING AREA READY?
Objects thrown by the trimmer can cause serious injury. Before
operating the trimmer, carefully inspect the area and remove all
objects that could be thrown by, or entangled in, the cutting
attachment, such as rocks, broken glass, nails, wire, or string.
Clear the area of children, bystanders, and pets. Keep all children,
bystanders, and pets at least 50 feet (15 meters) away from where the
trimmer is being operated.
Even outside a 50-foot (15-meter) radius of the trimmer, there may be
a risk of injury from thrown objects, so bystanders should be
encouraged to wear eye protection.
If anyone approaches you while you are operating the trimmer,
release the throttle trigger and stop the engine.
• If using a metal blade on a trimmer equipped with a loop handle, be
sure the barrier bar (optional part) is installed beneath the loop
handle.
• Make sure the cutting attachment is properly installed and securely
fastened (see page 23 and page 20).
• Check that the debris shield is the correct shield for the cutting
attachment (see page 20), and that it is securely installed and in
good condition.
Maintenance Inspection
• Check the oil level (see page 15). Running the engine with a low oil
level can cause engine damage.
• Check the air filter (see page 15). A dirty air filter will restrict air flow
to the carburetor, reducing engine and trimmer performance.
• Check throttle cable free play (see page 15). The cable must be
correctly adjusted and operate smoothly for good throttle control.
• Check the fuel level (see page 17). Starting with a full tank will help
to eliminate or reduce operating interruptions for refueling.

Adjusting the Harness
SAFE OPERATING PRECAUTIONS
Adjust the harness so the quick-release latch is at your right hip, as
shown.
Before operating the trimmer for the first time, please review the
IMPORTANT SAFETY INFORMATION section on page 2 and
BEFORE OPERATION section starting on page 9.
Even if you have operated other trimmers, take time to become
familiar with the operation of this trimmer’s controls and handling.
For your safety, avoid starting or operating the engine in an enclosed
area, such as a garage. Your engine's exhaust contains poisonous
carbon monoxide gas which can collect rapidly in an enclosed area
and cause illness or death.
If the trimmer starts to shake or vibrate, stop the engine immediately.
After the cutting head has completely stopped, inspect it to determine
the cause of the vibration. Sudden vibration is a sign of a hazardous
problem, such as a loose or damaged blade. Do not operate the
trimmer until the problem is corrected.

Balancing the Trimmer on the Shoulder Harness
Hang the trimmer on the harness hook, and see how it balances.
Adjust the shoulder harness, the harness hanger on the frame pipe,
and the loop handle or U-type handlebar, so the handle or handlebars
are in a comfortable operating position, and the trimmer hangs with its
cutting attachment a few inches above the ground (see page 11).
Prolonged exposure to vibration may cause Hand-Arm Vibration
Syndrome (HAVS). Symptoms include loss of skin color in the hands
and numbness or a painful tingling sensation in the fingers, hands,
and arms. Regular users of any power equipment may feel the
numbness or pain spontaneously, at any time, not just after using the
equipment. If any of these symptoms occur, see a physician
immediately.

trimmer under control at all times.
• Keep firm footing and
balance.
• Do not overreach.
HOOK
• Keep the cutting
attachment below waist

Throttle Operation
Using Blades
Pull the throttle trigger toward the grip to increase engine speed and
start the cutting attachment rotation.
Refer to the chart on page 18 for appropriate blade applications.
The trimmer has the greatest cutting force at maximum engine speed.
Release the throttle trigger to reduce engine speed. At idle, the cutting
attachment should coast to a stop.
If using a blade on a Honda trimmer equipped with a loop handle, also
install the optional Honda conversion kit that includes a full shoulder
harness, a barrier bar, and a debris shield for blades. Follow the
installation instructions and safety information that come with the kit.
Metal blades supplied with U-type handlebar models are supplied with
a cover surrounding the edge of the blade. For your safety, and to
protect the blade, the cover should be installed whenever the trimmer
is not in use.

Using a Nylon Cutting-Line Head
As the ends of the line wear away, more line must be released from
the cutting-line head. Your trimmer is factory-equipped with either a
manual-feed or a semi-matic (bump feed) cutting-line head, which
have different procedures for releasing line.
If the trimmer starts to vibrate after the blade strikes an object, stop
the engine immediately and check the blade for damage. A damaged
blade may break, and pieces of broken blade can become dangerous
projectiles. Replace the blade if it is broken, cracked, bent, or
damaged in any way.
SAFE OPERATING PRACTICES
Be very careful when operating the trimmer over uneven or rough
ground, and when the ground is wet and slippery. Watch out for
hidden obstacles that could cause you to stumble. Operate the
trimmer only under conditions with good visibility. Do not operate the
trimmer where you cannot see what it is cutting.
B WARNING
The debris shield is equipped with a cutoff knife that automatically
removes any excess line that is released.
Manual-Feed Cutting-Line Head
Line must be released with the cutting-line head stopped.
1. Stop the engine, and wait for the cutting-line head to coast to a
complete stop.
2. Hold the housing, pull the spool out about a quarter of an inch, and
then turn the spool counterclockwise. Pull the two lines until the
spool snaps into the housing again.
The spool will snap into the housing every sixth of a turn, which
releases 1 to 1-1/2 inches of line. Repeat until the proper length of
line is obtained.
To release more line,
pull spool and turn
counterclockwise.
Rotating cutting lines can cause serious abrasions and cuts,
and blades can cut deeply.
•
Keep away from the cutting lines or blade whenever the
engine is running.
•
Always stop the engine, and be sure the cutting line head
or blade has stopped turning, before inspecting or
handling the cutting lines or blade.
Thrown Debris
The trimmer will throw debris in the direction of blade movement at
the point of contact.
The cutting line head or blade rotates counterclockwise, as viewed
from the operator’s position. Tilting the cutting line head to the right
will throw debris away from you, and tilting to the left will throw debris
toward you.

Semi-Matic (bump-feed) Cutting-Line Head
Line must be released with the cutting-line head spinning rapidly.
With the engine running at full speed, tap the cutting-line head on
hard, bare ground. Do not tap the cutting-line head on pavement or
concrete.
If the cutting line head or blade is held parallel to the ground, debris
will scatter in all directions and there will be greater friction, which will
wear out the cutting line or blade sooner.
Each tap releases about 2 inches of line.
When operating the trimmer near a hard surface such as a wall, work
from an angle where debris that strikes the hard surface will ricochet
away from you.
SPOOL
HOUSING

Gravel, loose stones, etc. can be picked up by the nylon cutting lines
or blade and thrown many feet with enough force to cause serious
personal injury and/or property damage. Before crossing graveled
areas, release the throttle trigger to stop the cutting line head or
blade.
Blade Thrust (Kickback)
Trimming and Edging
Blade thrust (kickback) is the sudden, forceful, and uncontrolled
movement of a blade-equipped trimmer that may occur if the blade
binds while cutting or strikes a solid object.
Use nylon line for cutting against a hard surface. Work from an angle
where debris that strikes the hard surface will ricochet away from you.
Blade thrust (kickback) throws the trimmer in the direction opposite
blade rotation at the point of contact, and the jolt received by the
operator can result in further loss of control.
Avoid contact with wires, wire fences, metal rods, etc. Overlapping a
wire will cause the nylon line to wrap around the wire and break off.
DEBRIS
TRIMMING
BLADE
THRUST
To reduce the risk of loosing control, use metal blades on trimmers
equipped with a U-type handlebar, or install the barrier bar (optional
part) on trimmers equipped with a loop handle.
Brush Clearing
Replace or resharpen dull blades. Dull blades are more likely to bind
in the cut and cause blade thrust.
Scything with the right side of the blade will direct thrown debris away
from you.
Watch out for hidden obstacles such as rocks, stumps, roots, etc., that
could cause the blade to kick back if struck. Blade thrust is more likely
to occur in areas where it is difficult to see what is being cut.
Be especially careful to direct debris away from you if recutting an
area to shorten stumps. Short lengths of shrub and sapling stumps
may tear off and be thrown at high speed.
Understand the reaction forces of the blade. When using a brush
blade to saw through heavy brush and small saplings, saw with the
side of the brush blade that is moving toward you and tends to pull the
trimmer away from you.
Sawing heavy brush and saplings with the left side of the blade will
reduce the risk of kickback.
Blades on Honda HHT25S and HHT35S trimmers rotate
counterclockwise, as viewed from the operator’s position. Therefore,
the left side of the blade is moving toward you. With these trimmers,
sawing with the left side of a brush blade will give you better control
and less risk of kickback, though it will throw the sawdust toward you.
If shrubs or saplings bind the blade, stop the engine and, while
supporting the weight of the trimmer, push the shrub or sapling away
to free the blade. Do not use the blade as a lever.
Clearing brush with a brush blade may require both scything and
sawing.
Accelerate the engine to maximum speed before starting the cut, and
saw through with uniform pressure.
Cut from the side of saplings that will cause them to fall away from the
trimmer. This will help prevent the blade from binding in the cut and
kicking back.
Accelerate the engine to maximum speed before starting the cut, and
saw through with uniform pressure.
OPERATING TIPS
Scything
Swing the trimmer in a level arc by rotating your body with a smooth,
easy motion, rather then moving the trimmer with your arms. Do not
chop at tough weeds and brush; let the cutting line or blade work
through tough growths gradually.
To direct thrown debris away from you, tilt the cutting attachment to
the right side, scythe from left to right, then return without cutting.
SAWING
Operation on Slopes
Start on the low side of a slope, and work upward. This will reduce
your risk of slipping and falling, and it will give you a cutting angle that
will better enable you to direct debris away from you.
Do not let the cutting line or blade dig into the slope, because that can
cause stones and dirt to be thrown at you.
Do not raise the cutting attachment above waist level during
operation, because that would increase the risk of thrown objects
striking your face.
Avoid steep slopes that would require holding the cutting attachment
above waist level. Avoid slippery slopes that might cause you to lose
your balance.

universal applications. Although aftermarket attachments may fit on
your trimmer, they may not meet factory specifications and could
make your trimmer unsafe.
BLADES
If installing a metal blade on a Honda trimmer equipped with a loop
handle, also install the optional barrier kit that includes a full shoulder
harness, a barrier bar, and a debris shield for metal blades. Follow the
safety information and installation instructions that come with the kit.
Grass/Weed Blades
ATTACHMENTS FOR TRIMMING GRASS AND LIGHT WEEDS
Grass/weed blades, which may be
plastic or metal, are used as an
alternative to nylon monofilament line
for cutting grass and ordinary weeds.
However, blades should never be used
for edging against solid surfaces.
Weed/Brush Blades
These metal blades have
chisel-shaped teeth that are used for
cutting through field grass, thick weeds,
and light brush. They are not designed
for sawing woody material. The teeth
must be sharp for good results.
ATTACHMENTS FOR CUTTING THICK WEEDS AND LIGHT
BRUSH
Brush/Wood Blades
These metal saw-tooth blades are used
for sawing through saplings, shrubs
and woody brush. The teeth must be
sharp for good results. Brush/wood
blades will also cut grass and weeds,
but they are not efficient for that
purpose.
Blade Cover
Use the blade cover to protect yourself
from injury while installing or removing
the blade and to protect the blade from
damage during storage.
18
Blade Inspection
Always wear gloves when working around the blade. Before each
use, check the blade for wear and damage, and check the tightness of
the blade lock nut. Examine the entire head area, including the debris
shield, and clear or clean it free from dirt, debris, loose string, wire, or
any other foreign materials.
2. Insert a commercially available 4 mm hex tool or equivalent fully
into the gear case hole.

A dull blade is more likely to snag and thrust (kickback).
Inspect the blade regularly, and do not operate the trimmer
with a dull, worn, or damaged blade.
A dull blade can be sharpened, but a blade that is worn out, bent,
cracked, chipped, or otherwise damaged must be replaced.
When a blade needs sharping or replacement, take the trimmer to a
Honda trimmer servicing dealer. Or, if you have a torque wrench, you
can remove and install a blade yourself.
Blade Removal and Installation
3. Turn the blade until you feel the tool drop into the hole in cover
plate/spacer A. Verify the blade does not turn. The output shaft and
blade lock nut have a left-hand thread. Make sure the tool remains
in the hole, then loosen the blade nut as shown. Pay attention to
the order and orientation of the parts as they are removed.
4. Installation is the reverse of removal. Make sure you install the
blade with the cutting edges in the direction of rotation. Be sure to
align the hole in the blade with the shoulder on cover plate/
spacer A. Tighten the blade nut to the specified torque.
TORQUE: 15 ft-lb (20 N·m)
For loop handle models, a special optional Barrier Kit must be
installed before a blade can be used. Refer to the instructions
provided with each kit on how to install a blade on loop handle
models.
Always wear gloves and install the blade cover on the blade when
working around the blade.
A torque wrench is required to install the blade. If you do not have a
torque wrench, have a Honda trimmer servicing dealer tighten the
blade lock nut for you before using the trimmer.
If the blade lock nut is tightened too much, the output shaft can break.
If the blade lock nut is not tightened enough, the blade could come off.
In either case, it would be possible for the blade to fly off while you are
operating the trimmer.
The blade lock nut is specially designed for this application. When
replacing the lock nut, use only a Honda Genuine replacement lock
nut.
BLADE SHARPENING: To avoid weakening the blade or causing
imbalance or poor cutting, the blade should be sharpened by trained
staff at a Honda trimmer servicing dealer.
BLADE REPLACEMENT: Your Honda trimmer servicing dealer has
cutting attachments that have been designed and approved for your
trimmer and are covered by a warranty. Non-Honda attachments are
usually designed for universal applications. Although aftermarket
attachments may fit on your trimmer, they may not meet factory
specifications and could make your trimmer unsafe.

CUTTING-LINE HEADS
Manual-Feed Cutting-Line Head
All Honda trimmers come with either a manual or semi-matic cutting
head. Read this section to learn how to inspect, install new line, and
remove and install a cutting head from the trimmer.
Line is released from the cutting head by manually pulling and turning
the spool with the trimmer engine stopped.
A cutting-line head containing nylon monofilament line and a debris
shield with a cutoff knife is standard equipment. The shield’s cutoff
knife automatically removes any excess line that is released from the
cutting head.
To release more line,
pull the spool and turn
it counterclockwise.
The U-type handlebar trimmers are supplied with two different debris
shields. Use the debris shield with the cutoff knife when the
cutting-line head is installed.
Nylon monofilament line is suitable for cutting grass and ordinary
weeds, but not brush and woody growth.

Replacement Nylon Line instructions in this section to disassemble
the spool and replace the line.
Examine the entire head area, including the debris shield, and clear or
clean it free from dirt, debris, loose string, wire, or any other foreign
materials.
For the manual feed head, make sure the three-sided knob is
correctly tightened (page 22). For the semi-matic head, verify the
spool is locked in place (page 23). For both head styles, check for any
cracks in the plastic and replace any damaged parts.
Installing Replacement Nylon Line
First, determine which cutting-line head style is on your trimmer. A
manual-feed trimmer head has a three-sided knob on the bottom of
the head, while the semi-matic head has a spring-loaded round button
on the bottom of the head.
Do not use any kind of metal, wire, or wire rope line on the trimmer.
Use only Honda Genuine replacement nylon trimmer line or
equivalent.
Honda trimmers come standard with low noise line. Using non-Honda
line may result in increased noise levels.
For original, factory-installed Honda cutting-line heads, use only nylon
monofilament line in the line sizes shown below.

TRANSPORTING
HALF-ROUND
LOCKING HOLE
BEFORE LOADING
If the engine has been running, allow it to cool for at least 15 minutes
before loading the trimmer on the transport vehicle. A hot engine and
exhaust system can burn you and can ignite some materials.
Always turn the ignition switch to the STOP (O) position. Make sure
the fuel cap is securely tightened.
23
LOADING
The trimmer may be secured by suitable clamps, hangers or straps.
Secure the trimmer by at least two points along the frame pipe. Avoid
securing the trimmer by the engine, cutting head/gear case or handle
area. The trimmer should be secured in a horizontal position, with the
engine upright as shown.
Don't hang the trimmer by the gear case or cutting head, or they may
be damaged.
Fuel
NOTICE
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. Old gasoline will
cause hard starting, and it leaves gum deposits that clog the fuel
system. If the gasoline in your trimmer 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 DISTRIBUTORS LIMITED WARRANTY does not cover fuel
system damage or engine performance problems resulting from
neglected storage preparation.
STORAGE
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 Fuel Stabilizer to Extend Fuel Storage Life
Cleaning
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.
Add fuel stabilizer following the manufacturer's instructions.
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.
Wash the trimmer, including the area around the trimmer head.
Draining the Fuel Tank and Carburetor
Wash the engine by hand and be careful to prevent water from
entering the air cleaner.
Disconnect the spark plug cap. Make sure the ignition switch is in the
STOP (O) position.
Drain the fuel from the fuel tank into a suitable container. Press the
primer bulb a few times to draw any remaining fuel out of the
carburetor, then drain this fuel from the tank.
STORAGE PREPARATION
Proper storage preparation is essential to keep your trimmer trouble
free and looking good. The following steps will help to keep rust and
corrosion from impairing your trimmer's function and appearance, and
will make the engine easier to start when you use the trimmer again.
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.
If using a garden hose or pressure washing equipment to clean the
trimmer, be careful to avoid getting water into controls and cable, or
anywhere near the engine air cleaner or muffler opening.
Before washing the trimmer head area, disconnect the spark plug cap
from the spark plug.
After washing the trimmer, wipe dry all accessible surfaces.
Start the engine outdoors and let it run until it reaches normal
operating temperature to evaporate any water remaining on the
engine.
Stop the engine and allow it to cool.
After the trimmer is clean and dry, coat areas that may rust with a light
film of oil. Lubricate the control cable cores with a silicone spray
lubricant.
24
B 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 flames
away.
• Handle fuel only outdoors.
• WIpe up spills immediately.
Engine Oil
Change the engine oil (see page 15).
Carburetor & Air Cleaner
Clean the air filter (see page 15) and move the choke lever to the
CLOSED position.
Blade
If a blade is installed, put the blade cover on the blade.
Engine Cylinder
Remove the spark plug (see page 16). Pour a 1/4 tablespoon
(1 ~ 3 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.
STORAGE PRECAUTIONS
If your trimmer 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.
With the engine and exhaust system cool, cover the trimmer 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 non-porous
cover will trap moisture, promoting rust and corrosion.
REMOVAL FROM STORAGE
Check your trimmer as described in the BEFORE OPERATION
section of this manual.
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.

TECHNICAL INFORMATION
This section contains important information about serial number
locations, high altitude operation, and emission control systems.
Serial Number Locations

NUMBER
FRAME SERIAL NUMBER
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 utilizes appropriate air/fuel ratios and other emission 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
NOTICE
Tampering is a violation of Federal and California law.
There are two serial numbers, one for the trimmer and one for the
engine. Record these numbers in the space provided. You will need to
have these numbers available when ordering parts or making
technical or warranty inquiries (page 28).
Engine serial number: _____________________________
Frame serial number: ______________________________
Date of purchase: _________________________________
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 speed-adjusting mechanism to cause the
engine to operate outside its design parameters.
Problems That May Affect Emissions
Carburetor Modifications for High Altitude Operation
If you are aware of any of the following symptoms, have your engine
inspected and repaired by your servicing dealer.
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 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.
Replacement Parts
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.

The emission control systems on your new Honda engine were
designed, built, and certified to conform with EPA, 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 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 emission
regulations.
Maintenance
Follow the MAINTENANCE SCHEDULE on page 14. Remember 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.
Air Index
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 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 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

EMISSION CONTROL SYSTEM WARRANTY
Your new Honda Power Equipment engine complies with the U.S. EPA,
Environment Canada, and State of California emission regulations (models
certified for sale in California only). American Honda Motor Co., Inc. provides
the emission warranty coverage for engines in the United States and its
territories. Honda Canada Inc. provides the emission warranty for engines in
the 13 provinces and territories of Canada. In the remainder of this Emission
Control System Warranty, American Honda Motor Company Inc. and Honda
Canada Inc. will be referred to as Honda Canada 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 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.
OTHER STATES, U.S. TERRITORIES, AND CANADA
In other areas of the United States and in Canada, your engine must be
designed, built, and equipped to meet the U.S. EPA and Environment Canada
emission standards for spark-ignited engines at or below 19 kilowatts. Specific
Honda products that do not meet the California emissions regulations can be
identified by a “Not for sale in California” decal.
ALL OF THE UNITED STATES AND CANADA
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.
OWNER'S WARRANTY RESPONSIBILITY:
As the power equipment engine owner, you are responsible for the performance
of the 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 the performance of all scheduled maintenance.
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.
You are responsible for presenting your power equipment engine to a Honda
Power Equipment dealer as soon as a problem exists. The warranty repairs
should be completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your warranty rights and responsibilities,
you should contact the Honda Office in your region:

WARRANTY COVERAGE:
Honda power equipment engines sold in all of the United States and Canada
are covered by this warranty for a period of two years from the date of delivery
to the original retail purchaser or the length of the Honda Distributor’s Limited
Warranty, whichever is longer. This warranty is transferable to each subsequent
purchaser for the duration of the warranty period.
If any emission-related part on your engine is defective, the part will be repaired
or replaced by Honda without charge for diagnosis, parts, or labor. All defective
parts replaced under this warranty become the property of Honda. A list of
warranted parts is in the adjacent column. Normal maintenance items, such as
spark plugs and filters, that are on the warranted parts list are warranted up to
their required replacement interval only.
Honda will also replace other engine components damaged by a failure of any
warranted part during the warranty period.
30
Only Honda approved replacement parts may be used in the performance of
any warranty repairs and must be provided without charge to the owner. The
use of replacement parts not equivalent to the original parts may impair the
effectiveness of your engine emission control system. If such a 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.
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 his
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 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 Power Equipment Customer Relations
Department in your region. Refer to adjacent column for contact information.
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.
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.
DISCLAIMER OF CONSEQUENTIAL DAMAGE AND LIMITATION
OF IMPLIED WARRANTIES:
American Honda Motor Co., Inc. and Honda Canada disclaim 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, U.S.
EPA or Environment Canada emission control system warranty regulation is in
effect.
