Discs, knife bolts and knives are made of hard-alloy hardened materials. Therefore, to ensure

by original parts specified in the spare parts catalog.
Replacement of knives is made in the following cases:
- knife is bent;
- width of the knife is less than 30 mm (Figure 3.5) (measure 10 mm from the edge of the rotor
disk);
- length of the knife is less than 90 mm (Figure 3.6);
