 Insert the counter spanner 6
under the red sleeve 5. The
spindle is now unlocked.  Turn the three star grip to the right (clockwise) for
tightening and to the left (anticlockwise) for
loosening. The drive now turns only until a latched
bracket 4 is in contact with 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.
Only use type "C" grinding bowls.
This, in conjunction with the grinding bowl fixture, is a safety
component.
Unforeseen risks may arise if third-party or old grinding
bowls are used in the PM100.
Never allow grinding bowl clamping arrangement 3 to lie
loose in the grinding bowl fixture without the grinding bowls
being clamped in.
Danger of being hurled out!
Especially in cases of lengthy grinding periods, check at the
intervals in the following schedule that the grinding bowl is
sitting securely:
after 3 mins, after 1h, after 5h and then every 10-12h. A
gripping force of 10Nm is the optimum for the grinding bowl
clamping fixture.
Risk of being hurled out!
Safety Instructions for starting the PM 100
The grinding bowl clamping fixture has proven its worth over many years as an easy-to-manage and
reliable appliance. A precondition here both for the operator’s safety and also to ensure that the
components have a long service life is that the grinding bowl must be clamped conscientiously.
Please bear in mind that the PM 100/200 is a grinder that inputs a very high level of energy into the
material being ground and the grinding bowl must therefore be clamped conscientiously.
To avoid operating errors, the correct grinding bowl clamping is queried each time before the
machine starts.
Personnel who are particularly well trained and very familiar with how the PM is operated may hide
this safety instruction permanently. However, we particularly advise against this if the operating
personnel vary!
The software for the PM 100/200 is set up in such a way that each time before the machine starts
up, when the starting button is activated, it is necessary to confirm in the following display that the
grinding bowl has been clamped.
