– Press any button to wake up the robotic
mower – the status screen appears
( 10.13)
Fault:
Docking not working
Possible cause:
– Uneven entry area to docking station
– Dirty drive wheels or dirty floor plate
– Perimeter wire incorrectly routed in
area of docking station
– Ends of perimeter wire not cut
Remedy:
– Level out the entry area to the docking
station ( 9.5)
– Clean the drive wheels and the floor
plate of the docking station (
– Re-route the perimeter wire – ensure
correct routing in the area of the
docking station ( 9.6)
– Cut the perimeter wire as described and
route it without excess length – do not
roll up protruding ends (
Fault:
The robotic mower travels past the
docking station or docks at an angle
Possible cause:
– Wire signal affected by
– Perimeter wire incorrectly routed in
area of docking station
Remedy:
– Link the robotic mower and docking
station again – ensure that the robotic
mower is in correct alignment to the
docking station ( 9.8)
– Re-route the perimeter wire – ensure
correct routing in the area of the
docking station ( 9.6)
Check for correct connection of the
perimeter wire ends in the docking
station ( 11.4)
146
Fault:
The robotic mower has crossed the
perimeter wire
Possible cause:
– Perimeter wire incorrectly routed,
clearances are not correct
– Slope inclination of mowing area too
steep
– Interference affecting the robotic mower
Remedy:
– Check the routing of the perimeter wire
( 10.14); check the clearances with
the iRuler (
– Check the routing of the perimeter wire;
block off areas with excessively steep
slope inclinations (
15.2)
– Contact a VIKING specialist dealer ( )
Fault:
The robotic mower frequently becomes
stuck
9.7)
Possible cause:
– Cutting height too low
– Drive wheels dirty
– Depressions or obstacles in the mowing
area
Remedy:
– Increase the cutting height (
– Clean the drive wheels (
– Fill up holes in the mowing area, install
no-go areas around obstacles such as
exposed roots, remove obstacles
( 9.6)
Fault:
The impact sensor is not activated when
the robotic mower hits an obstacle
Possible cause:
– Low obstacle (height less than 8 cm)
11.5)
10.14)
9.3)
15.2)
– The obstacle is not firmly attached to
the ground – e.g. fallen fruit or tennis
ball
Remedy:
– Remove the obstacle or block it off with
a no-go area ( 11.8)
– Remove the obstacle
Fault:
Driving tracks at edge of mowing area
Possible cause:
– Excessively frequent edge mowing
– Starting points in use
– Battery is charged very frequently
towards the end of its service life
– Offset drive home (passage) not
switched on
Remedy:
– Switch off edge mowing or reduce it to
once per week ( 10.14)
– Start all mowing operations at the
docking station in suitable mowing
areas ( 10.15)
– Replace the battery – observe
corresponding recommendation in the
display ( ) ( 23.)
– Switch on offset drive home (passage)
( 10.14)
Fault:
Unmown grass at edge of mowing area
Possible cause:
– Edge mowing switched off
– Perimeter wire routed inaccurately
– Grass is out of reach of mowing blade
Remedy:
– Mow the edge once or twice per week
( 10.5)
– Check the routing of the perimeter wire
( 10.14); check the clearances with
the iRuler ( 11.5)
