INSPECTION OF KNIVES AND SECURING ELEMENTS
A. KNIVES :
Should be inspected systematically each time before the machine is operated.
Cutting quality as well as safe operation depend on the regular inspection and care given to the knives. Knives
should be replaced in the following cases :
1. Damaged knives
Very rough conditions can cause knives to crack and become deformed leading to :
- increased risk of accidents ;
- deterioration of cutting quality ;
- risk of damage to the cutterbar.
2. Worn knives
The width (B) of a knife, measured at a distance
of 10 mm away from the edge of the disc should
be greater than 3/4 the nominal width of the knife.
The hole (L) for the securing bolt must not become oval by more than :
20 mm for a hole of 18 mm
18 mm for a hole of 16 mm
B. SECURING ELEMENTS :
To be inspected regularly !
(particularly the tightening torque of the nut)
- Inspect immediately after hitting an obstruction.
- Inspect when replacing knives.
To avoid creating an out-of-balance force, the
two KUHN knives fitted per disc must always
be the same type .
- Check at the beginning of each season.
