1. Make sure the chuck key is at the 12 o’clock position in a vertical stance. Put the machine into back gear on a very low setting.

3. Make the Chuck revolve backward. Operate it at the lowest speed in back gear to do this. As the jaw connects with the wood, you should undo the Chuck.  
4. The tricky part involves locking the spindle. This process can lead to gear damage. Take caution not to put a bar across the jaws. This effort will strip the teeth off.

If the Allen wrench flips around, you are protected as the wood will stop it. Make sure the drive is engaged in providing a little more resistance using a strap wrench. If you need more force, you can use a hammer, but this can cause damage to the gears. You can try wrapping a mutton cloth wrapped around the handle to avoid this. A dead blow will be the best option not to damage the Allen wrench.
