12.2 Checking blade wear

Maintenance interval:
Before each use.
Risk of injury!
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.
A worn blade may break off and
cause serious injuries. The
instructions for blade maintenance
must therefore always be
observed.
