Remove knife screws A (8 pcs) and lock washers E & D (4 pcs each). Remove knife F. Sharpen or replace the
knife. Mount the knife with screws and lock washers. Sharpen knives in pairs to keep lengths the same and
maintain disk balance.
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.
