Sharpening Cutting Knives - Farmi CH27 ACR Operation, Maintenance And Spare Parts Manual

SHARPENING CUTTING KNIVES

Sharpen all knives equally.
This ensures disk balance.
!
Avoid heating the knife
during sharpening.
CAUTION!
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 without 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.
