Inserting and clamping grinding bowls in the PM200
1 2 3 4
5 Up = free 5 Down = locked
Only operate the PM200 with grinding bowls up to a
maximum nominal volume of 125ml. In order to avoid
unpleasant vibrations, 2 grinding bowls with the same gross
weight must always be inserted.
 Clean grinding bowl disk 1
 Insert grinding bowl 2 into the grinding bowl fixture
 Insert threaded spindle 4 with pressure piece into the
latching brackets 3
 Pull red sleeve 5 upwards and clamp the grinding bowl by
turning the three-point grip to the right
 Let red sleeve 5 latch audibly downwards, if necessary,
retighten gently
 It should now be impossible to turn the three-point grip.
Should the red locking sleeve not move completely
downwards when released (audible clacking), briefly retighten
threaded spindle 4.
The red locking sleeve, which is now in the locked position,
prevents the threaded spindle becoming loose.
Tightening and loosening the grinding bowl
clamping fixture using the counter spanner
The counter spanner prevents the drive turning while the grinding bowl clamping fixture is being
tightened or loosened!
 Push the counter spanner 6
under the red sleeve 5, the
spindle is now released  To clamp, pull the three-point grip to the right
(clockwise direction) and to loosen, pull to the left
(anticlockwise). The drive now turns only as far as till
a latching bracket 4 rests against the counter spanner
6. Easy tightening or loosening is then possible.
 For the PM200 the counter spanner 6 must be turned
180° and inserted when the grinding bowl fastening
device is in the highest lock-in position.
