According to the query on the official website of Borui Shaver, the steps are as follows.
1. Open the stubble compartment of the shaver, remove the upper cover of the stubble compartment, and pull out the bright silver metal device together.
2. There are four hexagonal screws on the front of the shaver. Use the corresponding hexagonal wrench to unscrew them and remove the front panel of the shaver and the bright silver switch fixed protection device.
3. Push from the back of the shaver toward the charging port, and the shaver will separate from the middle of the side of the shaver body, completely separating the back shell of the shaver from the entire shaver.
