battery connection WARNING Keep out of reach of children. NOTICE • Do not add tap water to the battery. Fill with distilled water, otherwise the battery service life will be shortened. • Do not add distilled water over the electrolyte upper level mark. If you do, electro- lyte will spill out and damage engine parts. If spillage occurs, it must be cleaned up immediately. Do not delay. • Make sure not to connect the battery leads in reverse order. Otherwise, a short- circuit may occur as a result.
pre-operation Pre-Operation Inspection ENGINE OIL CAUTION Use 4-stroke engine oil, API service classification SE class or equivalent. Check the API service label on the oil container to be sure it includes the letters SE class or equivalent. 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. SAE VISCOSITY GRADES 10W-30 5W-30 Ambient Temperature CHECKING THE OIL LEVEL 1. Remove the dipstick and clean it with a dry towel. 2. Reinsert the dipstick into the oil filling hole without screwing it in, remove it. The oil level can be determined by seeing how much of the dipstick is covered in oil. 3.
pre-operation NOTICE Running with insufficient engine oil may damage the gasoline engine. This is not covered by warranty. AIR CLEANER Dismantle the air cleaner cover and check its element to ensure it is clean and in good condition. Clean or replace it as necessary. NOTICE Never run the engine without an air filter. Severe wear and tear may occur as a result. This damage is not covered by warranty. FUEL RECOMMENDATION 1. Remove the fuel tank cap and check fuel level. 2. If the level is too low, refuel the tank. Remember to add fuel below the fuel shoulder. WARNING Gasoline is extremely flammable and is explosive under certain conditions. Refueling in a well-ventilated area with the engine stopped. Do not smoke and do not allow flames or sparks in the area where gaso- line is stored or where the fuel tank is refueled.

pre-operation Fuel Filler Shoulder Maximum Fuel Level Fuel Filler NOTICE Fuel may damage the exterior of the engine. Be careful not to spill fuel when refueling. Any damage due to spillage of any kind is not covered by warranty. A “light knocking” or “spark exploding” sound may be heard during engine overloading - this is normal. If “ knocking” or “spark exploding” sound occurs at a steady speed under normal load, change brand of gasoline. If this issue persists, contact your local service center or repair depot. NOTICE When the engine is running, continuously “Knocking” or “spark exploding” sound will damage engine.

high altitude operation High Altitude Operation At high altitude, the standard 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. High altitude performance can be improved by specific modifications to the carburetor. If you always operate your engine at altitudes above 1000 meters, have your servicing dealer perform the necessary modifications (not covered under warranty). NOTICE Modified engines applicable to altitude may be seriously damaged in areas below an altitude of 1000 meters due to overheating. This is because the mixture ratio is too lean for operation in a low altitude area. Operation at altitudes below 1000 meters with a modified carburetor may cause the engine ...

exhaust control system Exhaust Control System With the engine running, carbon monoxide, oxide of nitrogen and hydrocarbon will be produced. In certain conditions, oxide of nitrogen and hydrocarbon will chemically react to each other to produce carbon monoxide, an odorless toxic gas. As a result, exhaust control is very important. To keep the exhaust of your engine in line with emission standards, ensure that you perform regular maintenance. 1. MAINTENANCE Maintain the engine periodically in accordance with the maintenance schedule listed on the following page. The maintenance schedule is designed for normal use in normal conditions. If used under heavy load, dusty/wet conditions, or in high temperature, the engine should be serviced more frequently. 2. PROBLEMS AFFECTING EXHAUST EMISSIONS • Difficult starting or stopping. • Unstable idle speed. • Black exhaust or high fuel consumption. • Poor ignition sparks or backfire. • Advanced ignition. If you find or experience any of the problems listed above, contact your local ...

maintenance 2. MAINTENANCE METHOD 1) Replacement of engine oil (see page 9 to check method) Drain the engine oil rapidly and completely out when the engine is hot. (1) Turn off the oil filler cap and drain plug to drain engine oil thoroughly. REPLACING ENGINE OIL Reinstall the drain plug and screw in securely.
maintenance 1. Remove the air filter cover and take the element out. 2. Paper element: Wash the element with home detergents and warmwater (or non-flammable or high flash-point cleansing solvents) and dry. Foam element: Soak in clean engine oil until saturated. Squeeze out excess oil. Otherwise, the engine will smoke in starting stage. 3. Clean the air cleaner cover and inner surface with a wet cloth. Be careful not to allow dust to enter the carburetor. 4. Reinstall the element and put the air cleaner cover on. SPARK PLUG Spark plug type: BPR6ES (NGK) or NHSP LD F7RTC In order to ensure normal running, the gap of the spark plug must be correct and there should be no deposits around the spark plug. 1. Remove the spark plug cap. 2. Clear away dirt around the spark plug base. 3. Dismantle the spark plug with a spark plug wrench. 4. Visually check the spark plug. Clean with a steel brush. If the insulator is damaged, replace the spark plug. 5.
transport and storage Transport and Storage Transport with the fuel valve turned to the “OFF” position. Transport or store the engine when it is cool to avoid burns or fire. NOTICE To avoid spills, do not place the engine on an incline. Spilled fuel or fuel vapors may ignite and cause a fire. If the engine is not kept in use for a long time, be sure to store it properly. 1. Make sure the storage area is dry and free of dust. 2. Turn the fuel valve to the “OFF” position and place a fuel container under the carburetor (as shown below).
