Failure to follow this maintenance schedule could result in non-warrantable failures.

SAFETY PRECAUTIONS

• 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.

REFUELING

This engine is certified to operate on unleaded gasoline with a pump octane rating of 86 or higher.
We recommend refueling after each use to minimize the air present in the fuel tank.
Refuel in a well-ventilated area with the engine stopped. If the engine has been running, allow it to cool first. Never refuel the en gine inside a building where gasoline fumes may reach flames or sparks.
You may use regular unleaded gasoline containing no more than 10% ethanol (E10) or 5% methanol by volume. In addition, methanol must contain solvents and corrosion inhibitors. Use of fuels with content of ethanol or methanol greater than shown above may cause starting and/or performance problems. It may also damage metal, rubber, and plastic parts of the fuel system. In addition, ethanol is hygroscopic, which means it attracts and retains water in the fuel system. Engine damage or performance problems that result from using a fuel with percentages of ethanol or methanol greater than shown above are not covered by warranty.
If your equipment will be used on an infrequent or intermittent basis (more than 4 weeks between usage), refer to the Fuel section of the STORAGE chapter (page 9) for additional information regarding fuel deterioration.
Never use stale or contaminated gasoline or oil/gasoline mixture. Avoid getting dirt or water in the fuel tank.

WARNING

Gasoline is highly flammable and explosive, and you can be burned or seriously injured when refueling.

1. Stop engine and keep heat, sparks, and flame away.
2. Refuel only outdoors.
3. Wipe up spills immediately

Adding Fuel

See Figure 1, page 3.

1. Remove the fuel tank cap.
2. Add fuel to the bottom of the fuel level gauge [1] in the neck of the fuel tank. Do not overfill. Wipe up spilled fuel before starting the engine.
3. Install the fuel tank cap and tighten it until it clicks.
   Move at least 10 feet (3 meters) away from the fueling source and site before starting the engine.

NOTICE

Fuel can damage paint and some types of plastic. Be careful not to spill fuel when filling your fuel tank. Damage caused by spilled fuel is not covered under your Distributor’s Limited Warranty.

AIR CLEANER

A properly maintained air filter will help prevent dirt from entering your engine. Dirt entering the carburetor can be drawn into small passages in the carburetor and cause premature engine wear. These small passages can become blocked, causing starting or running problems.
You will need to clean the filter more frequently if you operate the engine in very dusty areas.

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 your Distributor’s Limited Warranty.
We recommend the use of a Honda Genuine air filter to ensure it seals and performs as designed. Using a non-Honda air filter can result in dirt bypassing the filter, causing damage to the engine or fuel system.

Inspection

See Figure 4 on page 3.

1. Press the latch tabs [1] on the top of the air cleaner cover [2], and remove the cover.
2. Remove the foam element [3] from the air cleaner cover.
3. Remove the screen grid [4] from the paper element [5].
4. Check both elements to be sure they are clean and in good condition.
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.
7. Set the paper element and screen grid in the air cleaner body [6], and install the air cleaner cover.

Cleaning
See Figure 4 on page 3.
Wipe dirt from the air cleaner body [6] and cover [2] using a moist rag.
Be careful to prevent dirt from entering the air duct [7] that leads to the carburetor.
Paper Element: Tap the filter 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.
Foam Element: Wash the element in a solution of household detergent and warm water and 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.
SPARK PLUG
See Figure 5 on page 3.
Recommended Spark Plug:
NGK BPR6ES – Pressure washer applications
NGK BPR5ES – All other applications The recommended spark plug is the correct heat range for normal engine operating temperatures.

NOTICE
Incorrect spark plugs can cause engine damage.
For good performance, the spark plug must be properly gapped and free of deposits.

1. Disconnect the cap from the spark plug, and remove any dirt from the spark plug area.

2. Use the proper size spark plug wrench [1] to remove the spark plug.

3. Inspect the spark plug. Replace it if damaged, badly fouled, if the sealing washer [2] is in poor condition, or if the electrode is worn.

4. Measure the electrode gap with a suitable gauge. The correct gap is 0.028 ~ 0.030 in (0.70 ~ 0.80 mm). If adjustment is needed, correct the gap by carefully bending the side electrode.

5. Install the spark plug carefully, by hand, to avoid cross-threading.

6. After the spark plug is seated, tighten with the proper size spark plug wrench to compress the washer.
   When installing a new spark plug, tighten 1/2 turn after the spark plug seats to compress the washer.
   When reinstalling the original spark plug, tighten 1/8 ~ 1/4 turn after the spark plug seats to compress the washer.
   NOTICE
   Properly tighten the spark plug. A loose spark plug can become
   very hot and can damage the engine. Overtightening the spark
   plug can damage the threads in the cylinder head.

7. Attach the spark plug cap to the spark plug.

FLYWHEEL BRAKE INSPECTION (if equipped)

See Figures 6 and 7 on page 3.

1. Remove the three flange nuts [1] from the recoil starter [2], and remove the recoil starter from the engine.
2. Remove the fuel tank [3] from the engine without disconnecting the fuel tube [4]. If the fuel tank contains fuel, keep it level as you remove it and set it beside the engine in a level position.
3. Check the brake shoe [5] thickness. If it is less than 3 mm, take the engine to your authorized Honda servicing dealer.
4. Install the fuel tank and recoil starter, and tighten the three nuts securely

SPARK ARRESTER (if equipped)

See Figure 8 on page 3.

The spark arrester may be standard or an optional part, depending on the engine type. In some areas, it is illegal to operate an engine without a spark arrester. Check local laws and regulations. A spark arrester is available from authorized Honda servicing dealers.
The spark arrester must be serviced every 100 hours to keep it functioning as designed.
If the engine has been running, the muffler will be hot. Allow it to cool before servicing the spark arrester.

2. Install the spark arrester in the reverse order of removal.

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.
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.
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 month of inactivity, or even less if the gasoline was not fresh when you filled the fuel tank.
Gasoline will oxidize and deteriorate in storage. Deteriorated gasoline will cause hard starting, and it leaves gum deposits that can clog the small passages in 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.
If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline. If it takes more than 3 months to use the fuel in your storage container, we suggest adding a fuel stabilizer to the fuel when you fill the container.
Fuel system damage or engine performance problems resulting from neglected storage preparation are not covered under your engine warranty.

Short Term Storage (30 – 90 days)
If your equipment will not be used between 30 and 90 days, we recommend the following to prevent fuel-related problems:

1. Add fuel stabilizer following the manufacturer’s instructions. 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.
   Note:

   • All stabilizers have a shelf life and their performance will deteriorate over time.
   • Fuel stabilizers will not reconstitute stale fuel.

2. 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.

3. Turn the fuel valve to the OFF position.

4. Continue to run the engine until it stops from the lack of fuel in the carburetor fuel bowl. Running time should be less than 3 minutes.

Long Term or Seasonal Storage (greater than 90 days)
Start the engine and allow it to run long enough to empty all the gasoline from the entire fuel system (including the fuel tank). Do not allow gasoline to remain in your engine for more than 90 days of inactivity.

ENGINE OIL

1. Change the engine oil (see page 7).
2. Remove the spark plug (see page 8).
3. Pour 1 – 2 teaspoons (5 ~ 10 cc) of clean engine oil into the cylinder.
4. Pull the recoil starter several times to distribute the oil.
5. Reinstall the spark plug.

STORAGE PRECAUTIONS

If your engine will be stored with gasoline in the fuel tank, 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.
If there is gasoline in the fuel tank, leave the fuel valve in the OFF position.
Keep the engine level in storage. Tilting can cause fuel or oil leakage.
With the engine and exhaust system cool, cover the engine to keep out dust. A hot engine and exhaust system can ignite or melt some materials. Do not use sheet plastic as a dust cover. A nonporous cover will trap moisture around the engine, promoting rust and corrosion.
REMOVAL FROM STORAGE
Check your engine as described in the BEFORE OPERATION CHECKS section of this manual (see page 4).
If the fuel was drained during storage preparation, fill the tank with fresh gasoline. If you keep a container of gasoline for refueling, be sure it contains only fresh gasoline. Gasoline oxidizes and deteriorates over time, causing hard starting.
If the cylinder was coated with oil during storage preparation, the engine will smoke briefly at startup. This is normal.

TRANSPORTING

Keep the engine level when transporting to reduce the possibility of fuel leakage. Turn the fuel valve to the OFF position.
Review the instructions provided with the equipment powered by this engine for any procedures that should be followed for transporting.

TECHNICAL INFORMATION

Serial Number and Type Location
See Figure on page 1.

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.

Carburetor Modifications for High Altitude Operation

At high altitude, the standard carburetor air-fuel mixture will be too rich. Performance will decrease, and fuel consumption will increase. A  very rich mixture will also foul the spark plug and cause hard starting.
Operation at an altitude that differs from that at which this engine was certified, for extended periods of time, may increase emissions.

High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above 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.

When auto throttle type engines are used in high altitude applications, the ability to idle down to 2500 rpm could be diminished. See your servicing dealer for information on adjustments if your auto throttle unit does not idle down with the load released or has trouble returning to full rpm with the load applied.

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

Source of Emissions
The combustion process produces carbon monoxide, oxides of  nitrogen, and hydrocarbons. Control of hydrocarbons and oxides of nitrogen is very important because, under certain conditions, they react to form photochemical smog when subjected to sunlight. Carbon monoxide does not react in the same way, but it is toxic.
Honda utilizes appropriate air/fuel ratios and other emissions control systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons. Additionally, Honda fuel systems utilize components and control technologies to reduce evaporative emissions.
The U.S. EPA, CARB, and Environment Canada
EPA, California, and Canadian emissions 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.
Tampering with or altering the emission control system may increase emissions beyond the legal limit. Among those acts that constitute tampering are:

• Removal or alteration of any part of the intake, fuel, or exhaust systems.
• Altering or defeating the governor linkage or speed-adjusting mechanism to cause the engine to operate outside its design parameters.

Problems That May Affect Emissions
If you are aware of any of the following symptoms, have your engine inspected and repaired by your servicing dealer.

• Hard starting or stalling after starting.
• Rough idle.
• Misfiring or backfiring under load.
• Afterburning (backfiring).
• Black exhaust smoke or high fuel consumption

Replacement Parts
The emission control systems on your Honda engine were designed, built, and certified to conform with EPA, California, and Canadian emission regulations. We recommend the use of Honda Genuine parts whenever you have maintenance done. These original-design replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance. The use of replacement parts that are not of the original design and quality may impair the effectiveness of your emission control system. A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emission performance. The manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the engine to comply with emission regulations.
Maintenance
Follow the maintenance schedule on page 6. 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.
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 (page 13) for additional information.

Distributor’s Limited Warranty
The applicable warranty is the warranty policy in effect in the country where the warranty service is provided.

PRODUCTS COVERED BY THIS WARRANTY:| LENGTH OF WARRANTY:

(FROM DATE OF ORIGINAL PURCHASE)

---|---
PRIVATE/ RESIDENTIAL (1)| COMMERCIAL/RENTAL/ INSTITUTIONAL (2)
GSV Series Engines| 24 months| 12 months

1. Private Residential: Used in maintaining owner’s primary and/or secondary residence. Any other use, including but not limited to informal “for hire” use, is considered commercial/rental/institutional.
2. Honda GCV general purpose engines are not covered by this warranty when installed on concession type vehicles.

To Qualify for this Warranty:
The Honda general purpose engine must be purchased from a Honda general purpose engine dealer or distributor authorized to sell that product in the United States, Puerto Rico, or the U.S. Virgin Islands. This limited warranty applies to first retail purchaser and each subsequent owner during the applicable warranty time period.
What American Honda Will Repair or Replace Under Warranty:
American Honda will repair or replace, at its option, any part that is proven to be defective in material or workmanship under normal use during the applicable warranty time period. Warranty repairs and replacements will be made without charge for parts or labor. Anything replaced under warranty becomes the property of American Honda Motor Company, Inc. All parts replaced under warranty will be considered as part of the original product and any warranty on those parts will expire coincident with the original product warranty.
To Obtain Warranty Service:
You must take your Honda general purpose engine, or the equipment in which it is installed, together with proof of original retail purchase date, at your expense, to a Honda engine dealer or distributor authorized to sell that product in the United States, Puerto Rico, or the U.S. Virgin Islands, during their normal business hours. Many Honda engine dealers and distributors are listed in the yellow pages of the telephone directory under gasoline engines, lawn & garden equipment & supplies, etc.
If you are unable to obtain warranty service, or are dissatisfied with the warranty service you receive, take the following steps: First contact the owner of the dealership or distributor involved. Normally this should resolve the problem. However, if you should require further assistance, write or call the Power Equipment Customer Relations Department of American Honda Motor Co., Inc. listed in the adjacent column.
Exclusions:
This warranty does not extend to parts affected or damaged by the product in which the engine is installed, or by collision, misuse, neglect, parts worn beyond service limits due to normal wear/normal service life, parts affected or damaged by the conversion to or use of fuel other than the fuel(s) which the engine is originally manufactured to use, poor operation related to fuel contamination or fuel quality, parts damaged by fuel contamination, the incorporation of, or use of, unsuitable attachments or parts, the unauthorized alteration of any part or any causes other than defects in material or workmanship of the engine. Use of the Honda general purpose engine for racing or competition will void this warranty. Any engine that is part of a product that has ever been declared a total loss or sold for salvage by a financial institution or insurer.
Disclaimer of Consequential Damage and Limitation of Implied Warranties:
American Honda disclaims any responsibility for loss of time or use of the engine, or the equipment in which the engine is installed, transportation, commercial loss, or any other incidental or consequential damage. Any implied warranties are limited to the duration of this written limited warranty. Some states do not allow limitations on how long an implied warranty lasts and/or do not allow the exclusion or limitation of incidental or consequential damages, so the above exclusions and limitations may not apply to you. This warranty gives you specific legal rights, and you may also have other rights which vary from state to state.
International Warranty
See last pages.

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.
YOUR WARRANTY RIGHTS AND OBLIGATIONS:

CALIFORNIA
The California Air Resources Board and Honda are pleased to explain the emission control system warranty on your 2014 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, 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.
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 (see page 2 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:

Relations
4900 Marconi Drive
Alpharetta, Georgia 30005-8847

or

Telephone: 888-946-6329

WARRANTY COVERAGE:
Honda power equipment engines sold in 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. 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 reverse side 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.
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 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, misfuelling, 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 Inc. 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.
