NOTICE!
Grinding disks are worn down during grinding. That is why
the grinding gap needs to be checked and readjusted if nec-
essary depending on the use and the degree of wear. This is
done as described in Ä Chapter 6.3 ‘Setting the zero point’
on page 25 andÄ Chapter 6.4 ‘Setting the gap width’
on page 27.
6.5 Revers mode
If the grinding disks are worn on one side, the Revers mode can be
selected.
1.
To switch from the "Parameter" menu to the "Check/Setup"
menu, press the arrow keys (c,d) until the - and + symbols on the
bottom right of the display have a black background. Switch to the
Check/Setup menu then by pressing the keys + (a) or - (b).
2. Use the arrow keys (c,d) to select Revers and then activate (On) or
deactivate (Off) the Revers mode with the + (c) or - (d) keys
respectively.
NOTICE!
Grinding disks are subjected to natural wear after
longer use and need to be replaced when necessary.
If you notice that the grinding disks are worn on one
side, they do not need to be replaced right away. You
can change the drive motor's direction of rotation by
using the Revers setting. After that, the abrasive
edges on the back side of the grinding disk are uti-
lised. At this point at the latest, replacement grinding
disks should be ordered. (See Ä Chapter 9.2
‘Exchanging the grinding disks (5 + 6)’ on page 39)
