Tighten the blade bearings with a torque of 75–80 Nm

IMPORTANT INFORMATION
When tightening the blade shaft screws,
the transmission side should always be
tightened first and then the blade
screws.
The belt pulley can be turned the wrong
way, the thicker side should be turned
downwards towards the blade.
An oil filter wrench, for example, can be used to
hold the pulley in place when the screw is
tightened.
