Ethanol gasoline
If ethanol gasoline is used, please use #90 or higher conforming to GB18351-2004. Do not use methanol gasoline, even though it may contain
cosolvent and anti-corrosion agent.
Note!
• If ethanol gasoline is exposed to water excessively, ethanol may be separated, resulting in decrease of gasoline octane number. Therefore,
the storage time shall not be too long.
• Before using ethanol gasoline for the first time, make a through cleaning of the fuel supply system and fuel tank.
• Always buy a proper amount of ethanol gasoline. Once there is a poor fuel tank sealing or a long storage time, moisture content may increase,
causing low octane number and resulting in difficult ignition or weak power.
Lubricant
(Please refer to Regular Maintenance Table)
Use high quality 4-stroke engine oil to prolong engine life. Engine oil shall be SE or SD product in API classification. Engine oil of proper viscosity
shall be used according to local air temperature. There are three viscosity levels suitable for the engine, namely, SAE15W-40, SAE10W-30 and
SAE5W-30. Refer to the figure below: SE or SF level SAE10W-30 4-stroke lubricant is recommended.
Note←
Lubricant shall be replaced at 1000km or about one month for the first time, every 3000km thereafter. Oil volume is 850ml for replacement or
1300ml after overhaul.
The quality of engine oil is a major factor affecting the service life of engine. Replace engine oil according to the maintenance period stated in
maintenance table (please refer to Page 19). When driving in dusty area, engine oil shall be replaced more frequently than the stipulations in
the maintenance table.
