   along the arrow, and it can be loaded into the nut

2. Install the collet and the nut on the shank or machine tool shaft together, wipe the tool cylinder handle into the clamping hole, and tighten

   the nut evenly with the wrench, until the tool clamp can be used (Note: install tools before fasten the nut so as not to damage the collet)

3. When changing the tools, release the nut and collet with the wrench, unload the tools, push the collet along the arrow direction, make it

    quit, and then change the other collet you needed
