10. Grip the clamp directly over the turning point then and turn it all
the way back.
11. The grinding set is pressed upward out of the gap by the ball pres-
sure pieces and can be pulled forward towards the body by the
grips.
12. It can happen that the grinding set sticks to the rubber plate and
cannot be moved forward because of that. A thin, firm object
(such as a knife) can be slid between the rubber plate and the
grinding set to loosen the rubber plate. Afterwards, the rubber
plate ought to be treated with talcum (bicycle or automotive
accessories), which greatly reduces the adhesion. This should be
repeated weekly.
The cause for the adhesion is due to the grinding set getting too
hot during grinding. The rubber is resistant to temperatures only
up to 200 °C. If the rubber becomes blistered, it should be
replaced. The grinding set can also stick if it was clamped in for a
longer duration.
