Installing the mowing blade:
● Clean the blade, carrier plate and
fastening nut prior to installation.

nut (2) on the carrier plate (3) as
illustrated. Ensure correct position of the
retainers (4) in the mowing blade.
Screw on the fastening nut (1) as far as
possible. Several clicks are audible during
tightening. Ensure secure seating of the
mowing blade by shaking carefully.
● Following installation of a new mowing

Risk of injury!
Check the blade for damage before
installing. The blade must be
replaced if notches or cracks are
identified or if its width is less than
25 mm, or its thickness is less than
1,3 mm at any point. (Ö 16.3)
The carrier plate and the
fastening nut must also be
replaced if damaged (e.g. broken,
worn). The fastening nut in
particular must engage cleanly in
the carrier plate.
Only new mowing blades are
balanced with the necessary
precision and guarantee proper
functioning of the machine as well
as low noise emissions.
The carrier plate can be removed in
order to clean the mowing deck.
