Before each use
●
Tilt the mower upwards into the
cleaning position. (
●
Clean the mowing blade (1) and check
it for damage (notches or cracks) and
wear; replace if necessary.
●
Use a slide calliper (not included in
standard equipment) to measure blade
thickness at 5 points at least. In
particular, the minimum thickness must
also be ensured in the area of the blade
wings.
●
Place a ruler (2) against the front blade
edge and measure permissible
grinding.
Wear limits:
Distance A:
The cutting edges may not be ground back
by more than
1
5 mm
.
Distance B:
The minimum width of the mowing blade
must not be less than

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.
In order to prevent damage to the
blade fastening screw, use a
suitable 22 mm hexagon socket
(not included in standard
equipment).
Risk of injury!
The mowing blade (2) must only be
installed as shown. The tabs (6)
must face downwards (to the lawn)
and the curved wings must point
upwards (to the machine).
Observe the specified torque of
1
0
-
1
5 Nm
when tightening the
blade fastening screw, as the
secure attachment of the cutting
tool depends on this. Additionally
secure the blade fastening
screw (3) with
Loctite 243
.
The blade fastening screw (3) must
be replaced each time the blade is
replaced.
