How to repair the oil injection hole of the electric chain saw
If the electric chain saw does not spray oil, there may be air inside. The solution is:

- Check whether there is air in the oil circuit. If there is air causing no fuel injection, remove the air from the oil circuit and the fault can be eliminated.
- Check whether the oil supply of the oil pump is normal, and repair the oil pump if necessary.
- Check the fuel system for oil leakage, and repair and tighten all connecting parts.
Extended information:

Although there are many different brands and models of Electric Chain Saws, their structures are similar and all conform to ergonomic design principles.
Chain brake - also known as brake, is a device used to quickly stop the rotation of the chain. It is mostly used to brake chain saws in emergency situations and is one of the safety functions.
