65 CH27 ACR & ACC
Sharpen all knives equally. This en-
sures disk balance.
Avoid heating the knife during shar-
pening.
The knives need sharpening when:
• The self-feeding of wood has decreased
• The power demand has increased
• The chip surface is rough
• The individual chips have become smaller.
Normally, the knives can be sharpened several times wit-
hout actually being removed (with, e.g., a sharpening stone
or belt grinder).
More thorough conditioning is carried out with a surface
grinder, with the knives removed.
Burrs are removed from the knife fastening bolt side,
grinding with the surface.
