Wear safety goggles
and gloves!
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.
l 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.
l Blades must not heat in the
process. They are destroyed
when they turn blue (glowed out
and soft).
l Do not round off the blade tips
(P).
l Do not grind the blades in a
curve (P).
l Use a grinding stone to re-
move any burr.
