deformed parts of the blade;

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. The blade must be statically balanced after each sharpening
To tighten the blade, use a torque wrench and a specified tightening torque of 60 Nm
If the blade is damaged it is prohibited to:
straighten it

When replacing worn-out parts follow these rules:
The permitted wear of the blade is 12 mm (0,5 inch). Blade must be replaced it the wear is higher than
permitted.
Balancing must be carried out after sharpening
The blade cannot be repaired / renewed.
When changing the blade, use new fastening bolts if the current ones show signs of damage. Only
high-tensile steel bolts may be used for this purpose. No other steel bolts are acceptable.
If the mowing mechanism vibrates when engaged, do not continue operating the mower, turn it off and
contact your local dealer.
