off and cause serious injuries. The
instructions for blade maintenance
must therefore always be
observed.
Mowing blades are subject 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
mowing blade will be subjected to
greater loads and will wear more
quickly than the average.
Check procedure:
The mowing blade (1) must be cleaned
thoroughly before each check procedure.
● Place the machine in the cleaning
position. (
Mowing blade thickness:
The blade thickness (A) must be ensured
at all points on the mowing blade. The
most important points are marked in the
illustration. (Check using slide calliper.)
A = 2 mm
Wear limit of the cutting edges:
The cutting edges must not be ground
back by more than distance (B) during
sharpening. When checking, place a
ruler (2) against the front blade edge (3)
and check for wear.
