Lubricating oil is easily deteriorated and burned. When the engine is operated at high temperature, the anti-oxidation stability of the lubricating oil deteriorates, exacerbating its thermal decomposition, oxidation and polymerization.
Avoid fire. When maintaining the crane, it is often necessary to use flammable and explosive materials such as oil, cleaning agents, etc. At this time, don't forget the fire fighting method and prepare a fire extinguisher to prevent if. Do not smoke near the fuel tank and battery: the combustible gas escaping from the fuel tank and the hydrogen escaping from the battery are simply lighted.
