It will also help reduce pollution. Improper maintenance, or failure to correct a problem before operation, can cause a malfunction in which you can be seriously hurt or killed. Always follow the inspection and maintenance recommendations and schedules in this owner’s manual. To help you properly care for your engine, the following pages include a maintenance schedule, routine inspection procedures, and simple maintenance procedures using basic hand tools. Other service tasks that are more difficult, or require special tools, are best handled by professionals and are normally performed by a Honda technician or other qualified mechanic. The maintenance schedule applies to normal operating conditions. If you operate your engine under severe conditions, such as sustained high-load or high-temperature operation, or use in unusually wet or dusty conditions, consult your Honda servicing dealer for recommendations applicable to your individual needs and use. Maintenance, replacement, or repair of the emission control devices and systems may be performed by any engine repair establishment or individual, using parts that are "certified” to EPA standards. MAINTENANCE SAFETV Some of the most important safety precautions follow. However, we cannot warn you of every conceivable hazard that can arise in performing maintenance. Only you can decide whether or not you should perform a given task. Failure to properly follow maintenance instructions and precautions can cause you to be seriously hurt or killed. Always follow the procedures and precautions in this owner’s manual. SAFETV PRECAUTIONS 0 Make sure the engine is off before you begin any maintenance or repairs. To prevent accidental startup, disconnect the spark plug cap. This will eliminate several potential hazards: *Carbon monoxide poisoning from engine exhaust. Operate outside, away from open windows or doors. *Burns from hot parts. Let the engine and exhaust system cool before touching. *lniury 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. 0 To reduce the possibility of fire or explosion, be careful when working around gasoline.

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 halfan 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 muff/er 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. 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. 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 whetherthe 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. Fuel system damage or engine performance problems resulting from neglected storage preparation are not covered underthe 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. Adding a Gasoline Sta zer 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. ENGLISH 1 3 fig 10/05/08 08:49 i 05 zzzekeooiom Draining the Fuel Tank and Carburetor Gasoline is highly flammable and explosive, and you can be burned or seriously injured when handling fuel. 0 Stop the engine and keep heat, sparks, and flame away. . Handle fuel only outdoors. . Wipe up spills immediately. 1.Move the fuel valve leverto the OFF position. 2. Place an approved gasoline container below the carburetor, and use a funnel to avoid spilling fuel. 3. Remove the carburetor drain bolt and gasket. Remove the sediment cup and O-ring, then move the fuel valve lever to the ON position. FUEL VALVE LEVER GASKET DRAIN BOLT SEDIMENT CUP 4. After all the fuel has drained into the container, reinstall the drain bolt, gasket, sedimentcup and O-ring. Tighten the drain bolt and sediment cup securely. Engine Oil 1. Change the engine oil lsee page 9 l. 2. Remove the spark plug (see page 12 l. 3. Pour a teaspoon 5710 cm1 (5* 10 ccl ofclean 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 rope slowly until resistance is felt and the notch on the starter pulley aligns with the hole at the top ofthe recoil starter cover. This will close the valves so moisture cannot enter the engine cylinder. Return the starter rope gently. Align notch on pulley with hole at top of cover. 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 spark- producing electric motor, or where power tools are operated. If possible, avoid storage areas with high humidity, because that promotes rustand corrosion. 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. If equipped with a battery for electric starter types, recharge the battery once a month while the engine is in storage. This will help to extend the service life of the battery. Removal from Storage Check your engine as described in the BEFORE OPERATION CHECKSsection of this manual lsee page 4 l. 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 overtime, causing hard starting. If the cylinder was coated with oil during storage preparation, the engine will smoke briefly at startup. This is normal. 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 lsee page 6 l. 14 ENGLISH A 10/05/08 08:49:25 3228R6007015 TAKING CARE OF UNEXPECTED PROBLEMS ENGINE WILL Possible Cause Correction NOT START 1.

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 1,500 meters (5,000 feetl, 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. ENGLISH Emission Control System Information Source of Emis ions 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 uti ‘ze components and control technologies to reduce evaporative emissions. The U.S., California Clean Air Act, and Environment Canada EPA, California, and Canadian regulations require all manufacturers to furnish written instructions describing the operation and maintenance of emission control systems. The following instructions and procedures must be followed in order to keep the emissions from your Honda engine within the emission standards. Tampering and Altering 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. a Altering or defeating the governor linkage or speed-adjusting mechanism to cause the engine to operate outside its design parameters. Problems That May Affect Em' sions 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. o Misfiring or backfiring under load. . Afterburning lbackfiring). - 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 lmodels certified for sale in Californial, and Canadian emission regulations. We recommend the use of Honda Genuine parts wheneveryou 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 ofthe 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. 17 A 10/00/24 15:00:40 3228176007018 Air Index Specifications (Models certified for sale in California) GX240/GX270 (PTO shaft type S, with fuel tank] An Air Index Information label is applied to engines certified to an Length X Width X 355 X 428 X 422 mm emission durability time period in accordance with the Height (14.0 X 16.9 X 16.6 in) requirements of the California Air Resources Board.
