creates friction, leading to
increased power consumption.
15.3 Checking the mowing blade wear
limits
Risk of injury!
A worn mowing blade may break 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 normal.
The mowing blade must be
replaced at least every
200 operating hours, resharpening
must be carried out by a VIKING
specialist dealer. (
● Activate the disabling device. (
● Tilt the robotic mower onto its side and
lean it securely against a stable wall.
Carefully clean the mowing deck and
mowing blade. ( 15.2)

Check the blade width A and blade
thickness B using a slide calliper.
If the blade width is less than 25 mm or the
blade thickness is less than 1,3 mm at any
point, the mowing blade must be replaced.
