mowing blade
● Activate the disabling 
device (Ö 5.2) and wear

● Tilt the robotic mower onto its 
side and lean it securely against a 
stable wall. Carefully clean the mowing 
deck and mowing blade. (Ö 16.2)
Removing the blade:
Push in both tabs (1) on the 
carrier plate with one hand and 
hold. Remove the fastening 
nut (2) with your other hand. 
Remove the mowing blade together with 
the fastening nut.
Installing the mowing blade:
● Clean the blade, carrier plate and 
fastening nut prior to installation.
Fit the mowing blade (1) and fastening 
nut (2) on the carrier plate (3) as 
illustrated. Ensure the correct position of 
the retainers (4) in the mowing blade.

Risk of injury!
Check the blade for damage before 
installation. 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.
