7. SERVICE
Grind the fixed knives
Information! The fixed knives are reversible. This means
that the fixed knife has two cutting edges and can be
reversed once before grinding or discarding is necessary.
Note! Fixed knives with IMD technology are reversible,
but not grindable.
1. Read page 7:16 “General rules, Grind the knives”.
2. Sharpen the fixed knife’s cutting edges by grinding
the knife’s top coat. Use a surface grinder. Grind until
all irregularities have disappeared.
3. Repeat point 2 until all fixed knives have been
grinded on one side.
4. Measure the knives’ thickness after grinding.
5. Select the most thin knife.
6. Grind the other side of the fixed knife.
7. Remove the knife but keep the settings on the surface
grinder.
8. Measure the knife’s thickness after grinding.
Note! If the fixed knife’s thickness is less than 10
mm, the fixed knife must be discarded and replaced
by a new fixed knife.
9. Repeat point 6–8 until all fixed knives have been
grinded on the other side.
Note! Grind all fixed knives equally. All fixed knives
must have the same measure and weight (within a
gramme).
Grind the scrapers
The scrapers are reversible and grindable. The scrapers
are grinded in the same way as the fixed knives, accept
from the fact that the scraper’s minimum thicknes is 8
mm.
Note! If the scraper’s thickness is less then 8 mm, the
scraper must be discarded and replaced by a new scraper.
