Action
Increase the mowing time, see 6.4
Timer (2) on page 49.
Try limiting the working area or
extending the working time, see 6.4
Timer (2) on page 49.
Replace all the blades and screws so
that the rotating parts are balanced.
Increase the cutting height and then
successively lower.
Check that the skid plate and blade
disc rotate easily. If not, the skid plate
and perhaps the blade disc must be
removed and the grass and foreign
objects removed. See 8.5 Cleaning
on page 72.
Set the clock, see Time and date
(4-4) on page 64.
Adjust the start and stop time settings
for mowing, see 6.4 Timer (2) on
page 49.
Inspect the blades and screws and
replace them if necessary.
No action. The blade disc does not
rotate when the mower is searching
for the charging station.
Dismantle and clean the skid plate
and blade disc.
No action.
