Restoring from service position

down and slide in the unit.
2 Replace the cutting height stay and the belt.

Checking the blades
To achieve the best mowing results it is important that the
blades are undamaged and well-sharpened.
Check that the blades’ attachment screws are tight.
The blades should be balanced after sharpening.
Damaged blades should be replaced when hitting obstacles
that result in a breakdown. Let the servicing dealer judge
whether the blade can be repaired/ground or must be
discarded.
