After 4–20 operating hours, de-
pending on the wear on the
knives, these become dull and
regrinding is necessary.
For this purpose, we recommend
using a hand grinder of 15,000
– 20,000 rpm with a pot-shaped
grinding pin of 25 mm in diam-
eter and approx. 35 mm in length
or a special grinding tool.
Grinding the knives is essential
for a clean and smooth opera-
tion.
Grinding is done using the
front of the grinding pin only,
guiding it from the back of the
knife to the tip of the blade.
Blades must not heat in the
process. They are destroyed
when they turn blue (glowed out
and soft).
Do not round off the blade tips
(P).
Do not grind the blades in a
curve (P).
Use a grinding stone to re-
move any burr.
