(This machine is a two-stroke gasoline engine with crankcase scavenging. The lubrication of the cylinder and transmission parts in the crankcase depends on the fuel system lubrication. Therefore, the fuel used by this machine is a mixture of gasoline and lubricating oil. Before the fuel is poured into the tank, Gasoline and gasoline engine oil are poured into the container according to a certain volume ratio, and mixed evenly before being poured into the fuel tank. Never pour the two kinds of oil into the fuel tank one after the other.)
Customer Note:
A new engine generally requires a running-in phase of more than 500 kilometers, and the same applies when the cylinder and piston ring are damaged and need to be updated. During the running-in phase, the speed should not exceed 20km/h, and the engine should not bear excessive load. Otherwise, it will cause the engine to overheat, seize the cylinder and accelerate the wear of parts.
