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.
If the blades hit a foreign body such as a stone, they should
be inspected before using them again.
The blades should be balanced after sharpening. Let the
servicing agent judge whether the blade can be repaired/
ground or must be replaced.
