Must not show signs of damage such as twisted,
bent or deformed parts of blades.
Must be properly attached by the flange in the
middle of blades.

The fastening bolts of the flange must not be
damaged.
For proper and reliable functioning the blades are
statically balanced by the manufacturer. This
balance must be preserved during the entire use of
the blade

sharpening
To tighten the blade, use a torque wrench and a
specified tightening torque of 60 Nm
If the blades are damaged, it is prohibited to:
Straighten them

Ream them or otherwise change their
construction.
When replacing worn-out parts follow these
rules:
The blade may only be sharpened within the
permitted wear limit. Balancing must be carried
out after sharpening.

turn it off and contact your local dealer.
