Inspection of knives and securing elements
Knives
Inspect systematically all knives before the machine is
operated to:
- ensure the cutting quality.
- ensure safety in use.
- Prevent cutterbar damage risks.
Replace knives in the following cases:
- Damaged knives. Very rough conditions can cause
knives to crack and become deformed.
- Worn knives
Knife length C must exceed 65 mm (2.6’’).
Knife width B, measured at a distance A of 10 mm (0.4’’)
from the disc edge must exceed 20 mm (0.8’’).
The hole L for the securing bolt must not become oval by
more than 20 mm (0.8’’).
Always replace both knives per disc to avoid creating an
out-of-balance force.
Immediately replace worn or damaged parts with
genuine KUHN parts.
