How to install and use the nut?
The internal oval design of the nut is a normal design. It is recommended to install the chuck according to the following steps:
1. Insert the chuck diagonally from the side of the nut with the smallest oval diameter.
2. Gently push the chuck to make the chuck fully enter the inside of the oval.
3. After installing the chuck inside the nut, the fixture (for example: milling cutter, woodworking knife, etc.) is installed.
4. The disassembly steps are the same. (If there is a milling cutter, please remove the milling cutter first)
The priority is to install the chuck into the nut without falling, and then place it in the tool holder to tighten the nut.
The chuck is a spring chuck, the tighter the screw, the greater the clamping strength.
(According to the video installation method and disassembly)
