Kmix is making a grating sound when operating

SOURCE: can't remove beater kmix from machine. it's stuck!kenwood

Here's how to fix the stuck implement problem:

The implements each have adjustable heights. to adjust the height you need to loosen the bolt at the top with a 14mm spanner. If the bolt was loose when it was being used then it can get too short and not leave enough clearance between the bolt and the machine in order to push up and turn to release the implement. If this happens take the open ended spanner, grasp the implement and rotate the spanner clockwise (when looking up at the machine from below. Once the nut is loose rotate the implement until there is enough clearance to remove it normally.
