Fault:
Mowing operations are significantly
shorter than usual
Possible cause:
– Grass is very high or too wet
– Machine (mowing deck, drive wheels) is
very dirty
– Battery has reached end of service life
Remedy:
– Adjust the cutting height (
Set the rain sensor (
11.11)
Change the active times (
– Clean the machine (
16.2)
– Replace the battery – observe
corresponding recommendation in the
display ( ), (
24.)
Fault:
The robotic mower is docked, the battery is
not charging
Possible cause:
– Battery does not need to be charged
– Docking station not connected to power
supply
– Incorrect docking
– Charging contacts corroded
– Power supply unit defective
– Machine is in standby
Remedy:
– No action necessary – battery charging
occurs automatically below a certain
voltage
– Check power supply to the docking
station (
9.8)
– Place the robotic mower in the mowing
area and send it back to the docking
station (
11.6), check for correct
docking – if necessary, correct the
position of the docking station (
– Replace charging contacts ( )

( )
– Press any button to wake up the robotic
mower – status screen appears

Fault:
Docking not working
Possible cause:
9.5)
– Uneven entry area to docking station
– Uneven areas around or underneath
11.7)
docking station floor plate
– Docking station floor plate bent
– 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 entry area to docking station
(
9.1)
– Level out uneven areas around or
underneath docking station floor plate
(
9.1)
– Ensure that floor plate is level and flat
(
9.1)
– Clean drive wheels and docking station
floor plate (
– Re-route perimeter wire – ensure
correct routing in area of docking
station (
– Cut 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 environmental

9.10)
– Perimeter wire incorrectly routed in
area of docking station
Remedy:
– Link robotic mower and docking station
again – ensure that robotic mower is in
correct alignment to docking station
(
11.16)
– Re-route perimeter wire – ensure
correct routing in area of docking
station (
9.9)
Check for correct connection of
perimeter wire ends in docking station
(
9.10)
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 robotic mower
Remedy:
– Check routing of perimeter wire
(
11.13), check clearances using
iMOW® Ruler (
12.5)
– Check routing of perimeter wire; block
off areas with excessively steep slope
inclinations (
11.13)
– Contact your STIHL specialist dealer
( )
Fault:
The robotic mower frequently becomes
stuck
Possible cause:
– Cutting height too low
– Drive wheels dirty
