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 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’’).
Before adjusting, maintaining or repairing
the machine, perform the safety shutdown
procedure.
Immediately replace worn or damaged parts with
genuine KUHN parts.
Always replace both knives per disc to avoid
creating an out-of-balance force.
