Risk of injury!
A worn or damaged mowing blade
may break off and cause serious
injuries. The instructions for blade
maintenance must therefore always
be observed.
Blades are subjected to differing
degrees of wear depending on the
location and duration of use. If you
use the machine on sandy ground
or use it frequently under dry
conditions, the blade will be
subjected to greater loads and will
wear more quickly than the
average.
