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 34 mm (1.4’’).
The hole L for the securing bolt must not become oval by
more than 20 mm (0.8’’).
Immediately replace worn or damaged parts with
genuine KUHN parts.
Always replace both knives per disc to avoid
creating an out-of-balance force.
