5.4 Downtimes
NOTICE!
Risk of material damage due to medium remaining in the
Börger machine
If the medium remains in the Börger machine during storage
periods and long downtimes, it can cause material damage to the
wedge wire screen and make it more difficult to start the Börger
machine.
— It is essential to empty the Börger machine before storage or
long downtimes, especially with swelling media such as
paper.

can be restarted after a long downtime.
