SERVICING YOUR SNOWTHROWER REFUELING FUEL TANK CAPACITY: 0.3 US gallon (1.3 liters) Stop the engine, remove the cap, and check the fuel level. Refill the tank if the fuel level is low. Do not fill above the base of the filler neck. MAXIMUM FILL POINT WARNING Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel. • Stop the engine and keep heat, sparks, and flame away. • Handle fuel only outdoors. • Wipe up spills immediately.
SERVICING YOUR SNOWTHROWER FUEL RECOMMENDATIONS Use unleaded gasoline with a pump octane rating of 86 or higher. The engines is certified to operate on unleaded gasoline. Unleaded gasoline produces fewer engine and spark plug deposits and extends exhaust system life. Never use stale or contaminated gasoline or an oil/gasoline mixture. Avoid getting dirt or water in the fuel tank. Occasionally you may hear a light “spark knock” or “pinging” (metallic rapping noise) while operating under heavy loads.
SERVICING YOUR SNOWTHROWER Engine Oil Change Drain the oil while the engine is still warm to assure rapid and complete draining. DRAIN PLUG & WASHER 1. Place the snowthrower on a level surface. 2. Place a suitable container below the drain bolt to catch the used oil, then remove the oil filler cap/dipstick and the drain plug. 3. Allow the used oil to drain completely, then reinstall the drain plug, and tighten it securely. NOTICE Improper disposal of engine oil can be harmful to the environment.
SERVICING YOUR SNOWTHROWER Engine Oil Recommendations R SAE 5W-30 G II GY ERVICE IN IS SJ ENE SAE 5W-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. The SAE oil viscosity and service classification are on the API label on the oil container. Honda recommends that you use API SERVICE category SJ (or later) oil or equivalent with the “starburst” certification mark displayed on the container.
SERVICING YOUR SNOWTHROWER 2. Inspect the spark plug. Replace it if the electrodes are worn or if the insulator is cracked, chipped, or fouled with deposits. Make sure that the spark plug washer is in good condition. NOTICE Use only the recommended spark plugs or equivalent. Spark plugs which have an improper heat range may cause engine damage. A replacement spark plug may be purchased from a servicing Honda snowthrower dealer. See page 49 for a part number list.
SERVICING YOUR SNOWTHROWER AUGER Clutch Lever Free Play Inspection 1. Move the clutch lever until you feel resistance from the cable.

Loosen (don’t remove) the three flange nuts on the scraper blade. 3. Move the scraper blade down slightly. Tighten the self-locking nuts and recheck the clearance. FLANGE NUT (3) SCRAPER BLADE ADJUST POSITION TO SET 1/16 ~ 1/8 INCH (1 ~ 3 mm) GROUND CLEARANCE. Repeat the procedure as needed to get the necessary clearance.
STORAGE STORAGE PREPARATION Proper storage preparation is essential for keeping your snowthrower trouble-free and looking good. The following steps will help to keep rust and corrosion from impairing your snowthrower’s function and appearance, and will make the engine easier to start when you use the snowthrower again. Cleaning 1. Rinse the auger housing and wheels with a garden hose. Wipe the rest of the snowthrower with a moist rag. 2. After the snowthrower has dried, touch up any damaged paint.
STORAGE Adding a Fuel Stabilizer to Extend Fuel Storage Life 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. If you keep a container of gasoline for refueling, be sure that it contains only fresh gasoline. Add fuel stabilizer following the manufacturer's instructions.
STORAGE Engine Oil 1. Change the engine oil (page 24). 2. Remove the spark plug (page 25). 3. Pour a tablespoon (5 ~ 10 cc) of clean engine oil into the cylinder. 4. Pull the starter rope slowly several times to distribute the oil. 5. Reinstall the spark plug. 6. Pull the starter grip until resistance is felt. This will close the valves and protect the engine from internal corrosion. Lubrication Apply a few drops of oil or a small amount of grease to the following parts for lubrication and rust prevention.
STORAGE STORAGE PRECAUTIONS If your snowthrower 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 it promotes rust and corrosion.
TRANSPORTING BEFORE LOADING If the engine has been running, allow it to cool for at least 15 minutes before loading the snowthrower on the transport vehicle. A hot engine and exhaust system can burn you and can ignite some materials. Turn the fuel valve to OFF. This will prevent carburetor flooding and reduce the possibility of fuel leakage.
TAKING CARE OF UNEXPECTED PROBLEMS Electric starter does not operate Possible cause Correction No electric power from the outlet. Try a known good electrical outlet. Start the engine by using the recoil starter. Defective power cord. Try another power cord. Start the engine with the recoil starter. Starter operates, but the engine will not start Possible cause Correction Fuel valve is OFF. Turn the fuel valve to ON (page 13). Stale or old fuel. Be sure the tank has fresh fuel.
TAKING CARE OF UNEXPECTED PROBLEMS Engine has low power Possible cause Correction Fast ground speed puts excessive load on the engine. Reduce your walking speed. Wet, deep snow puts an excessive load on the engine. Reduce the snowthrowing swath. Discharge chute is restricted. Clear the discharge chute of obstructions (page 18). Spark plug cap is not secure. Make sure the spark plug cap is securely connected. Improper electrode gap or deposits on the gap.
TAKING CARE OF UNEXPECTED PROBLEMS Snow not discharging properly Possible cause Correction Discharge chute is restricted. Clear the discharge chute of obstructions (page 18). Foreign object stopping the auger from rotating. Remove the foreign object. Auger not engaging because the drive belt is worn, broken, or not on the pulleys. See servicing Honda snowthrower dealer.

TECHNICAL & CONSUMER INFORMATION TECHNICAL INFORMATION Serial Number Locations Record the engine and frame serial numbers in the spaces below. You may need these serial numbers when ordering parts, and when making technical or warranty inquiries (page 55). ENGINE SERIAL NUMBER Use a flashlight to view through the hole for the exhaust pipe. The number starts with “GC...
TECHNICAL & CONSUMER INFORMATION Carburetor Modification 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.
TECHNICAL & CONSUMER INFORMATION Oxygenated Fuels Some conventional gasolines are being blended with alcohol or an ether compound. These gasolines are collectively referred to as oxygenated fuels. To meet clean air standards, some areas of the United States and Canada use oxygenated fuels to help reduce emissions. If you use an oxygenated fuel, be sure it is unleaded and meets the minimum octane rating requirement. Before using an oxygenated fuel, try to confirm the fuel's contents.
TECHNICAL & CONSUMER INFORMATION 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.
TECHNICAL & CONSUMER INFORMATION Replacement Parts The emission control systems on your new 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 originaldesign replacement parts are manufactured to the same standards as the original parts, so you can be confident of their performance.
TECHNICAL & CONSUMER INFORMATION 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.
