• FOR YOUR SAFETY
)
• PARTS AND CONTROLS
)
• BEFORE EACH OPERATION
)
• OPERATION
)
• MAINTENANCE SCHEDULE (
)
BEFORE EACH OPERATION
Your safety is your responsibility. A little time spent in preparation will significantly reduce your risk of injury. Read and understand this manual. Know what the controls do and how to operate them.
Familiarize yourself with the trimmer and its operation before you begin using it. Know how to quickly shut off the engine in case of an emergency.
Check Your Trimmer
For your safety, to ensure compliance with environmental regulations, and to maximize the service life of your trimmer, it is very important to take a few moments before you operate the trimmer 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 trimmer.
On blade equipped models, always remove the blade cover before starting the engine. If the cover is not removed, the blade cover may fly off at high speed during test operation. Reinstall the blade cover when the trimmer is not being used.
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.
Equipment
The Honda HHT25S and HHT35S trimmer/brush cutters are supplied with a shoulder harness and safety glasses. Refer to
for a description of other equipment and protective clothing you will need.

• Check that the debris shield is the correct shield for the cutting attachment (
)
Check Your Trimming Area
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.

).
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.
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.
Safe Trimming Practices
Honda trimmers are designed to give safe and dependable service if operated according to instructions and intended use.
Honda trimmers are intended to be used by an experienced, trained operator who is familiar with the use of power equipment. Do not allow a child or an inexperienced, untrained operator to use this trimmer.
Operating this equipment requires special effort on your part to ensure your safety and the safety of others. Read and understand this owner’s manual.
Always Wear Eye Protection and Protective Clothing
• 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.
• The operator must wear hearing protectors when using this trimmer. Hearing protectors will protect the operator's ears from noise damage.
• 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.
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.
• 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.
9
Turn the Engine Off When Not Trimming
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.
Read This Manual Before Using the Trimmer
Read the manual before operating the trimmer. Understand how to use all the controls and obey all warnings.
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.
Keep the Trimmer Properly Maintained
• The cutting attachment should be examined for looseness, cracks, broken parts, or excessive wear. Tighten or replace as needed before operating the trimmer.
• Do not operate the trimmer without a debris shield properly installed. Make sure you have the right shield installed for your cutting attachment.
Cutting Terrain
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.
WARNING
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.
DEBRIS
In general, cut with the right side to throw debris away from you.
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.
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.
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)
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.
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.
To reduce the risk of loosing control, use metal blades on trimmers
BLADE
THRUST equipped with a U-type handlebar, or install the barrier bar (optional part) on trimmers equipped with a loop handle.
Replace or resharpen dull blades. Dull blades are more likely to bind and cause blade thrust.
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.
Understand the reaction forces of the blade. 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, when using a brush blade to saw through heavy brush and small saplings, 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.
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.
10
OPERATING TIPS
Scything Motion
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.
Trimming and Edging
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.
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
Brush Clearing
Clearing brush with a brush blade may require both scything and sawing.
Scything with the right side of the blade will direct thrown debris away from you.
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.
Sawing heavy brush and saplings with the left side of the blade will reduce the risk of kickback.
Accelerate the engine to maximum speed before starting the cut, and saw through with uniform pressure.
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.
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.
Attachments and Modifications
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.
Attachments
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
CUTTING ATTACHMENTS (
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.
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.

Trimmer Operation
Operating Position
Hold the trimmer firmly with both hands, with your fingers and thumbs encircling the handles as shown. This will help you to keep the trimmer under control at all times.
• Keep firm footing and balance.
• Do not overreach.
• Keep the cutting attachment below waist level.
• Keep all parts of your body away from the rotating cutting attachment and hot surfaces.
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
Kwik Loader or a semi-matic (bump feed) cutting-line head, which have different procedures for releasing line.
The debris shield is equipped with a cutoff knife that automatically removes any excess line that is released.
Kwik Loader Cutting-Line Head
Always shut the engine off when adding trimmer line to the Kwik
Loader head.
To load, push the 8-inch trimmer line into the housing so there is
1/4 inch (6 mm) exposed in the inner housing radius. Do this for both sides.
The line will only move in one direction. Pull the trimmer line through the inner housing to unload.

If using a blade on a Honda trimmer equipped with a loop handle, also install the optional Honda barrier kit (
) that includes a full shoulder harness, a barrier bar, and debris shields 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.
Be sure to remove the blade cover before starting the engine.
Otherwise, the blade cover may fly off at high speed.
• 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.

Grass/Weed Blades
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.
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.
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.
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
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.
1. Install the protective plastic cover that came with the blade (U-type brush/wood blade only).
2. Insert a commercially available 4 mm hex tool or equivalent fully into the gear case hole.

Debris Shields
Always use the correct debris shield when operating the trimmer. In addition to safety concerns, it can cause an overload to the clutch due to excessive line length. Clutch failure due to running the trimmer without a shield installed is not covered under warranty.
A variety of blades are available from your Honda trimmer servicing dealer. Always use the debris shield designed for use with a blade when attaching a blade to your trimmer. The blade type debris shield does not have a cutoff knife.
Inspect the shield for excessive wear, damage, or looseness before each use. If the shield is damaged, it must be replaced.

Cutting-Line Heads
All Honda trimmers come with either a Kwik Loader 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.
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.
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.
CUTTING-LINE HEAD NYLON MONOFILAMENT LINE
Kwik Loader Cutting-Line Head
Always shut the engine off before adding trimmer line to the head. To load, push the 8-inch trimmer line into the housing so there is 1/4 inch
(6 mm) exposed in the inner housing radius. Do this for both sides.
The line will only move in one direction. Pull the trimmer line through the inner housing to unload.

Inspection
Make sure the nylon line is only sticking out of the metal eyelets on the head. If any of the line has come off the spool, follow the Installing
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 Kwik Loader head, make sure the three-sided knob is correctly tightened (
page 5 ). 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 Kwik Loader head uses two 8 inch long line segments, while the semi-matic head has a spring-loaded round button on the bottom of the head which automatically extends the line during use when bumped on the ground.
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.

8. When you have about 6 inches (150 mm) of line remaining, press the lines into the two notches on the bottom of the spool. This will hold the lines on the spool for reassembly.
9. Feed both line ends through the metal eyelets in the housing.
NOTCHES
It may be necessary to push down and rotate the outer drive until the round lugs align with the metal eyelets.
10.Align the channels in the spool with the round lugs on the outer drive. With the channels and notches aligned with the metal eyelets, slide the spool into the housing with a continuous snap-in motion. Be careful not to let the line slip under the spool. When the spool reaches the bottom of the housing, the lines should snap out of the spool notches.

TRANSPORTING
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.
1. Turn the engine switch to the OFF position.
2. Make sure the fuel cap is securely tightened.
3. Install the wheels in the transport position for greater ground clearance and ease of movement.
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.
STORAGE
Draining the Fuel Tank and Carburetor
WARNING
Gasoline is highly flammable and explosive, and you can be burned or seriously injured when handling fuel.
• Stop the engine and let cool before handling fuel.
• Keep heat, sparks, and flame away.
• Refuel only outdoors.
• Wipe up spills immediately.
Disconnect the spark plug cap. Make sure the ignition switch is in the
STOP position.
Drain fuel from the tank into an approved container. Press the primer bulb several times to draw any fuel out of the carburetor back to the fuel tank, and then drain this fuel from the tank.
Oil
Change the engine oil (see
Add oil in the engine cylinder to prevent rust.
1. Remove the spark plug (
).
2. Pour a 1/4 teaspoon (1 cc) of clean engine oil into the cylinder to keep it from rusting.
3. Pull the starter rope several times to distribute the oil in the cylinder.
4. Reinstall the spark plug.
5. Pull the starter rope slowly until resistance is felt, and then return the starter grip gently. This will close the valves so moisture cannot enter the engine cylinder.
Cleaning
1. Disconnect the spark plug cap from the spark plug.
1. Wash the trimmer, including the area around the trimmer head.
2. Wash the engine by hand, and be careful to prevent water from entering the air cleaner.
Proper storage preparation is essential for keeping your trimmer trouble free and looking good. To help keep rust and corrosion from impairing your trimmers function and appearance, and to make the engine easier to start after storage, follow the instructions described in this section to:
• Drain or treat the fuel
• Change the oil and coat the engine cylinder
• Clean the trimmer and engine
• Choose a storage location
Fuel
See “AVOIDING FUEL-RELATED PROBLEMS” on page 28
for a list of recommended procedures to avoid fuel related problems.
The DISTRIBUTOR’S LIMITED WARRANTY
cover fuel system damage or engine performance problems resulting from neglected storage preparation.
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.
3. 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.
4. If using a garden hose or pressure washing equipment to clean the trimmer, be careful to avoid getting water into controls and cables, or anywhere near the engine air cleaner or muffler opening.
5. After washing the trimmer, wipe dry all accessible surfaces.
6. Reconnect the spark plug cap and start the engine outdoors. 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.
7. After the trimmer is clean and dry, touch up any damaged paint, and coat other areas that may rust with a light film of oil.
24
Storage Location
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 dry storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a spark-producing electric motor, or where power tools are operated.
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 nonporous cover will trap moisture around the trimmer, promoting rust and corrosion.
Removing From Storage
Check your trimmer as described in BEFORE OPERATION (
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 may smoke briefly at startup. This is normal.

High Altitude Operation
At high Altitudes, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A very rich mixture will also foul the spark plug and cause hard starting.
Operation at an Altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions.
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
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.
U.S. EPA and CARB
U.S EPA and California emissions regulations require all manufacturers to furnish written instructions describing the operation and maintenance of emissions control systems.
The following instructions and procedures must be followed in order to keep the emissions from your Honda engine within the emissions standards.
Tampering and Altering
NOTICE
Tampering is a violation of federal and California law.
Tampering with or altering the emissions control system may increase emissions beyond the legal limit. Among those acts that constitute tampering are:
• 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
If you are aware of any of the following symptoms, have your engine inspected and repaired by your servicing dealer.
• Hard starting or stalling after starting
• Rough idle
• Misfiring, backfiring under load, or afterburning
• Black exhaust smoke or high fuel consumption
Replacement Parts
The emissions control systems on your new Honda engine were designed, built, and certified to conform with EPA and California emissions regulations. We recommend the use of Honda Genuine parts whenever you have maintenance done. These original-design replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance. Honda cannot deny coverage under the emission warranty solely for the use of non-Honda replacement parts or service performed at a location other than an authorized Honda dealership; you may use comparable
EPA certified parts, and have service performed at non-Honda locations. However, the use of replacement parts that are not of the original design and quality may impair the effectiveness of your emissions control system.
A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emissions performance. The manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the engine to comply with emissions regulations.
Maintenance
As the power equipment engine owner, you are responsible for completing all required maintenance listed in your owner's manual.
Honda recommends that you retain all receipts covering maintenance on your power equipment engine, but Honda cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure that all scheduled maintenance has been completed.
Follow the Maintenance Schedule on page 15
. 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.

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

PWL50623-W
EMISSION SYSTEM WARRANTY
Your new Honda Power Equipment engine complies with the U.S. EPA and
State of California (models certified for sale in California only) emission regulations. American Honda Motor Co., Inc. provides the emission warranty coverage for engines in the United States and its territories. In the remainder of this Emission Control System Warranty, American Honda Motor Co., Inc., will be referred to as Honda.
YOUR WARRANTY RIGHTS AND OBLIGATIONS:
CALIFORNIA
The California Air Resources Board and Honda are pleased to explain the emission control system warranty on your 2019 and later Honda Power
Equipment engine. In California, new spark-ignited small off-road equipment engines must be designed, built, and equipped to meet the state's stringent anti-smog standards. Specific Honda products that do not meet the California emissions regulations can be identified by a “Not for sale in California” decal.
OTHER STATES AND U.S. TERRITORIES
In other areas of the United States, your engine must be designed, built, and equipped to meet the U.S. EPA emission standards for spark-ignited engines at or below 19 kilowatts.
ALL OF THE UNITED STATES
Honda must warrant the emission control system on your power equipment engine for the period of time listed below, provided there has been no abuse, neglect, or improper maintenance of your power equipment engine. Where a warrantable condition exists, Honda will repair your power equipment engine at no cost to you including diagnosis, parts, and labor.
Your emission control system may include such parts as the carburetor or fuel injection system, the ignition system, and catalytic converter. Also included may be hoses, connectors, and other emission-related assemblies (see the adjacent column for additional covered parts).
OWNER'S WARRANTY RESPONSIBILITY:
As the power equipment engine owner, you are responsible for completing all required maintenance listed in your owner's manual. Honda recommends that you retain all receipts covering maintenance on your power equipment engine, but Honda cannot deny warranty coverage solely for the lack of receipts or for your failure to ensure that all scheduled maintenance has been completed.
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 emission related warranty repairs should be completed in a reasonable amount of time, not to exceed 30 days.
If you have any questions regarding your emission warranty rights and responsibilities, you should contact the Honda office in your region :
American Honda Motor Co., Inc.
Power Equipment Customer Relations
4900 Marconi Drive
Alpharetta, Georgia 30005-8847
Telephone: (888) 888-3139
Email: [email protected]
WARRANTY COVERAGE:
Honda power equipment engines sold in the United States 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. Only Honda approved replacement parts may be used in the performance of any warranty repairs and must be provided without charge to the owner. A list of warranted parts is on the adjacent column of this warranty statement. 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.
Honda cannot deny coverage under the emission warranty solely for use of non-Honda replacement parts or service performed at a location other than an authorized Honda dealership; however, use of a part that is not functionally identical to the original equipment part in any respect that may in any way affect emissions (including durability) could result in denial of coverage. If such a non-Honda replacement part is used in the repair or maintenance of your engine, and an authorized Honda dealer determines it is defective or causes a failure of a warranted part, your claim for repair of your engine may be denied.
If the part in question is not related to the reason your engine requires repair, your claim will not be denied.
TO OBTAIN WARRANTY SERVICE:
You must, at your own expense, take your Honda Power Equipment engine or the product on which it is installed, along with your sales registration card or other proof of original purchase date, to any Honda Power Equipment dealer who is authorized by Honda to sell and service that Honda product during their normal business hours. Claims for repair or adjustment found to be caused solely by defects in material or workmanship will not be denied because the engine was not properly maintained and used.
If you are unable to obtain emission warranty service or are dissatisfied with the warranty service you received, contact the owner of the dealership involved. Normally this should resolve your problem. However, if you require further assistance, contact the Honda office in your region. Refer to adjacent column for contact information.
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. disclaims any responsibility for incidental or consequential damages such as loss of time or the use of the power equipment, or any commercial loss due to the failure of the equipment; and any implied warranties are limited to the duration of this written warranty. This warranty is applicable only where the California and U.S. EPA emission control system warranty regulation is in effect.
