8.1 Replace wear bar
The wear bar must be replaced after every 50 hours of operation. The
replacement is done as follows:
1.
First the hood has to be opened and the eccentric clamping device
has to be released.
2. If there is a grinding set inserted, take it out.
3. Remove the worn wear bar with the help of a screwdriver by slip-
ping it under the bar and pressing up.
4. Insert the new bars with the rounded edges fitting into the groove
and press in.
The wear bars fit very precisely and need to be
pressed into the recesses with some force or with the
help of a rubber hammer.
