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

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 engine inside a building where gasoline fumes may reach flames or sparks.
Y ou may use regular unleaded gasoline containing no more than 10% ethanol (E10) or 5% methanol by volume. In addition, methanol must contain cosolvents 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.
WARNING
Gasoline is highly flammable and explosive, and you can be burned or seriously injured when refueling.
• Stop engine and keep heat, sparks, and flame away.
• Refuel only outdoors.
• 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.
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.
Fuel Storage Container
Store your gasoline in a clean, plastic, sealed container designed for fuel storage. Close the vent (if equipped) when not in use, and store the container away from direct sunlight. If it takes more than 3 months to use the fuel in the container, we suggest adding a fuel stabilizer to the fuel when you fill the container. If you have some fuel left in the storage container at the end of the season, the Environmental Protection Agency (EPA) suggests adding the gasoline to your vehicle’s gas tank (http://epa.gov/reg5oair/mobile/winter.html).

ENGINE OIL

Oil is a major factor affecting performance and service life. Use 4-stroke automotive detergent oil. Always change the oil in accordance with the maintenance schedule (page 7).
Recommended Oil
See Figure 2, page 3. Use 4-stroke motor oil that meets or exceeds the requirements for API
service category SJ or later. Always check the API service label on the oil container to be sure it includes the letters SJ or later.
SAE 10W-30 is recommended for general use. Other viscosities shown in the chart may be used when the average temperature in your area is within the indicated range.
7
Oil Level Check
NOTICE
NOTICE
NOTICE
NOTICE
See Figures 2, 3, page 3.
1. Check the oil with the engine stopped and level.
2. Remove the oil filler cap/dipstick [1] and wipe it clean.
3. Insert the oil filler cap/dipstick into the oil filler neck as shown, but do not screw it in, and then remove it to check the oil level.
4. If the oil level is near or below the lower limit mark [2] on the dipstick, remove the oil filler cap/dipstick, and fill with the recommended oil to the upper limit mark [3]. Do not overfill.
5. Reinstall the oil filler cap/dipstick [1].
Oil Change
See Figure 3, page 3. Drain the engine oil when the engine is warm. Warm oil drains quickly
and completely.
1. Turn the fuel valve to the OFF position to reduce the possibility of fuel leakage.
2. Place a suitable container next to the engine to catch the used oil.
3. Remove the oil filler cap/dipstick [1] and drain the oil into the container by tipping the engine toward the oil filler neck [4].
Please dispose of used motor oil in a manner that is compatible with the environment. We suggest you take used oil in a sealed container to your local recycling center or service station for reclamation. Do not throw it in the trash, pour it on the ground, or pour it down a drain.
4. With the engine in a level position, fill to the upper limit mark [3] on the dipstick with the recommended oil.
Refill amount: 12.0 ~ 13.5 oz (0.35 ~ 0.40 ) Always check the oil level with the dipstick after filling.
Running the engine with a low oil level can cause engine damage.
5. Reinstall the oil filler cap/dipstick [1] securely.

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.
Cleaning
See Figure 4, page 3.
1. Tap the filter several times on a hard surface to remove dirt, or blow compressed air not exceeding 30 psi (207 kPa) through the filter from the clean side that faces the engine. Never try to brush off dirt. Brushing will force dirt into the fibers.
2. Wipe dirt from the air cleaner body [4] and cover using a moist rag. Be careful to prevent dirt from entering the air duct [5] that leads to the carburetor.

SPARK PLUG

See Figure 5, 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.
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.
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.
Operating the engine without a filter, or with 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, page 3.
1. Press the latch tabs [1] on the top of the air cleaner cover [2], and remove the cover. Check the filter [3] to be sure it is clean and in good condition.
2. Reinstall the filter and air cleaner cover.

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

FLYWHEEL BRAKE INSPECTION (if equipped)

See Figures 6, 7, page 3. Start the engine outdoors. Move the throttle lever to the FAST position
and release the flywheel brake lever; the engine should stop quickly.
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)

NOTICE
NOTICE
See Figure 8, 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.
Removal
1. Remove the three 6 mm bolts [1] from the muffler protector [2], and remove the muffler protector.
2. Remove the special screw [3] from the spark arrester [4], and remove the spark arrester from the muffler [5].

Cleaning
If the engine has been running, allow it to cool for at least half an hour before cleaning. Clean all exterior surfaces, touch up any damaged paint, and coat other areas that may rust with a light film of oil.
Using a garden hose or pressure washing equipment can force water into the air cleaner or muffler opening. Water in the air cleaner will soak the air filter, and water that passes through the air filter or muffler can enter the cylinder, causing damage.
Fuel
Depending on the region where you operate your equipment, fuel formulations may deteriorate and oxidize rapidly. Fuel deterioration and oxidation can occur in as little as 30 days and may cause damage to the carburetor and/or fuel system. Please check with your servicing dealer for local storage recommendations.
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 ga s ol i n e w as no t fre s h 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)
Turn the fuel valve on, 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 8).
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.
9
Removal From Storage
NOTICE
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.

TAKING CARE OF UNEXPECTED PROBLEMS

Engine will not start
POSSIBLE CAUSE CORRECTION
Fuel valve is OFF. Move the fuel valve lever to ON. Choke is OFF. Unless the engine is warm, move
the choke/throttle lever, choke rod, or choke lever to the CHOKE position. (if equipped)
Ignition switch or engine stop switch is OFF.
Out of fuel. Refuel. Bad fuel; engine stored
without treating gasoline, or refueled with bad gasoline.
Spark plug faulty, fouled, or improperly gapped. Spark plug wet with fuel (flooded engine).
Fuel filter clogged, carburetor malfunction, ignition malfunction, valves stuck, etc.
Move the flywheel brake lever to RUN position. Throttle lever to FAST position. Engine stop switch to ON.
Refuel with fresh gasoline.
Adjust or replace the spark plug (page 8). Dry and reinstall the spark plug. Start the engine with the choke/throttle lever in the FAST position. Choke in the OFF position. Take the engine to an auth o r i z ed Honda servicing dealer or refer to the shop manual to replace or repair faulty components as necessary.

Radio Frequency Interference Label (Canada)

This engine complies with Canadian radio frequency interference regulations, ICES-002.
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.
Engine lacks power
POSSIBLE CAUSE CORRECTION
Air filter clogged. Clean or replace the air filter
(page 8).
Bad fuel; engine stored without treating the gasoline, of refueled with bad gasoline.
Fuel filter clogged, carburetor malfunction, ignition malfunction, valves stuck, etc.
10
Refuel with fresh gasoline.
Take the engine to an authorized Honda servicing dealer or refer to the shop manual to replace or repair faulty components as necessary.
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

NOTICE
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
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 7. Remember that this schedule is based on the assumption that your machine will be used for its designed purpose. Sustained high-load or high-temperature operation, or use in unusually wet or dusty conditions, will require more frequent service.
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 14) for addition al information.
