WARNING! Wear safety gloves when working on the blade and close to it! Use
proper tools to remove debris, e. g. a wooden stick! Never use your bare hands!
Always use original spare parts for replacement.
The replacement of the blade should be done by a qualified specialist! Rework or
sharpening blades is not recommended unless it is done by a repair service or a
similarly qualified specialist!

and work on the cutting device. Avoid tilting the product in order to prevent fuel
and oil leakages.
Keep the underbody and blade clean and free of debris. Remove clippings from the
discharge chute.
