cleaning position. (Ö 13.2)
● Clean mowing blade (1).
● Use a slide calliper to measure the 
blade thickness A at 5 points at least. 
In particular, minimum thickness must 
also be ensured in the area of the blade 
wings.
● Check the blade width B in the area 
marked in grey X at 3 points at least 
using a slide calliper.
Wear limits:
Blade thickness A: 1,6 mm
Blade width B: 56 mm
The blade must be replaced
– if it is damaged (notches, cracks),
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 average. A 
worn blade may break off and 
cause serious injuries. The 
instructions for blade maintenance 
must therefore always be observed.
