4.1 preparation before starting

Use more than 90 gasoline and special engine oil for two-stroke gasoline engine, with a mixing ratio of 20 ~ 25:1. Pay attention not to let dirt enter the fuel tank during refueling, and do not store the mixed oil in the fuel tank for a long time.

When the gasoline engine is shut down and the hot engine is started, the muffler is a high-temperature component, so avoid contacting the muffler components to avoid scalding. Turn down the throttle by 1 / 3 ~ 1 / 2 and start the engine.
