Bicycle shifter maintenance. How to open and cleaning bike shifter

Hello cyclist friends. This video tutorial is about the shifter on a bicycle.
It often happens that the speeds on the bike do not want to switch and in this video, we will look at the reasons why this happens.
I will show you all the steps, how to disassemble the shifter, how to clean and lubricate it.
I will also use a shimano sl-m310 derailleur.
