HELPFUL TIPS & SUGGESTIONS

STORING YOUR ENGINE

Draining the Fuel Tank and Carburetor

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.

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

Stop engine and keep heat, sparks, and flame away.

Handle fuel only outdoors.

Wipe up spills immediately.

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.

1.

Place an approved gasoline container below the carburetor, and use a funnel to avoid spilling fuel.

2.

Remove the drain bolt and gasket, and drain the carburetor bowl fuel into an approved gasoline container.

3.

Move the fuel valve lever to the ON position. This will allow the fuel tank to drain through the carburetor bowl.

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

Gasoline will oxidize and deteriorate in storage. Deteriorated gasoline will cause hard starting, and it leaves gum deposits that clog the fuel system. If the gasoline in your engine deteriorates during storage, you may need to have the carburetor and other fuel system components serviced or replaced.

CARBURETOR BOWL

GASKET

DRAIN BOLT

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.

ON

FUEL VALVE LEVER

OFF

Fuel system damage or engine performance problems resulting from neglected storage preparation are not covered under the

Distributor’s Limited Warranty.

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.

OFF

O N

Adding a Gasoline Stabilizer to Extend Fuel Storage Life

When adding a gasoline 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.

1.

Add gasoline stabilizer following the manufacturer’s instructions.

2.

After adding a gasoline stabilizer, run the engine outdoors for 10 minutes to be sure that treated gasoline has replaced the untreated gasoline in the carburetor.

3.

Stop the engine.

4.

After draining the carburetor bowl and fuel tank, move the fuel valve lever to the OFF position.

5.

Install the gasket and drain bolt, and tighten securely.

07/05/01 15:46:48 32Z4P600_012

Engine Oil

1.

Change the engine oil (see page 9 ).

2.

Remove the spark plug (see page 10 ).

3.

Pour a tablespoon 5 − 10 cm (5 − 10 cc) of clean engine oil into the cylinder.

4.

Pull the starter rope several times to distribute the oil in the cylinder.

5.

Reinstall the spark plug.

6.

Pull the starter grip slowly to the direction of the arrow as show below until resistance is felt. This will close the valves so moisture cannot enter the engine cylinder. Return the starter rope gently.

Removal from Storage

Check your engine as described in the

BEFORE OPERATION

CHECKS section of this manual (see page 3 ).

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.

Direction to pull

Storage Precautions

If your engine will be stored with gasoline in the fuel tank and carburetor, it is important to reduce the hazard of gasoline vapor ignition. Select a well-ventilated storage area away from any appliance that operates with a flame, such as a furnace, water heater, or clothes dryer. Also avoid any area with a sparkproducing electric motor, or where power tools are operated.

If possible, avoid storage areas with high humidity, because that promotes rust and corrosion.

Unless all fuel has been drained from the fuel tank, turn the fuel valve lever to the OFF position to reduce the possibility of fuel leakage.

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.

12

ENGLISH

07/05/01 15:47:04 32Z4P600_013

TRANSPORTING

If the engine has been running, allow it to cool for at least 15 minutes before loading the engine-powered equipment on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials.

Keep the engine level when transporting to reduce the possibility of fuel leakage. Turn the fuel valve to the OFF position (see page 6 ).

TAKING CARE OF UNEXPECTED PROBLEMS

Carburetor Modifications for High Altitude Operation

Date Purchased: ______ / ______ / ______

Remote Control Linkage

The control is provided with a hole for cable attachment. Install a solid wire cable or wire cable as shown below. Do not use braided wire cable.

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.

CONTROL LEVER

High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above 1,500 meters (5,000 feet), 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 300-meter (1,000-foot) increase in altitude. The effect of altitude on horsepower will be greater than this if no carburetor modification is made.

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 1,500 meters (5,000 feet) 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 lean carburetor settings and other systems to reduce the emissions of carbon monoxide, oxides of nitrogen, and hydrocarbons.

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 hightemperature operation, or use in unusually wet or dusty conditions, will require more frequent service.

The U.S., California Clean Air Acts 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

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 genuine Honda parts whenever you have maintenance done.

These original-design replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance. The use of replacement parts that are not of the original design and quality may impair the effectiveness of your emission control system.

A manufacturer of an aftermarket part assumes the responsibility that the part will not adversely affect emission performance. The manufacturer or rebuilder of the part must certify that use of the part will not result in a failure of the engine to comply with emission regulations.
