TROUBLE SHOOTING
The robotic lawnmower has got
caught in something.
The robotic lawnmower is stuck
behind a number of obstacles.
The boundary wire connections to
the charging station are crossed.
The boundary wire is too close to the
edge of the working area.
The working area slopes too much
by the boundary loop.
The boundary wire is laid in the
wrong direction around an island.
Disturbances from metal objects
(fences, reinforcement steel) or
buried cables close by.
The robotic lawnmower finds it hard
to distinguish the signal from an
installation close by.
Wrong PIN code has been entered.
Five attempts are permitted, and
the keypad is then blocked for five
minutes.
The robotic lawnmower has got
caught in something.
The working area includes a steep
slope.
The guide wire is not laid at an angle
on a slope.
The robotic lawnmower has got
caught in something.
The contact between the charging
strips and contact strips may be poor
and the robotic lawnmower has made
a number of charging attempts.
An object is obstructing the robotic
lawnmower.
There is an object in the way of the
robotic lawnmower, preventing it from
leaving the charging station.
The robotic lawnmower is leaning too
much or has turned over.
The robotic lawnmower is set to the
Secondary area operating mode.
Free the the robotic lawnmower and rectify the
reason for it becoming trapped.
Check if there are any obstacles which make it
hard for the robotic lawnmower to move on from
this location.
Check that the boundary wire is connected
correctly.
Check that the boundary wire has been laid
according to the instructions, see 3 Installation on
page 16.
Try moving the boundary wire.
Place the robotic lawnmower in the charging
station and generate a new loop signal, see 6.5
Security on page 47.
Enter the correct PIN code. Contact the local
dealer if you forget the PIN code.
Free the robotic lawnmower and rectify the
reason for the lack of drive. If it is due to wet
grass, wait until the lawn has dried before using
the robotic lawnmower.
Maximum guaranteed slope is 45%. Steeper
slopes should be isolated. Refer to page 20.
If the guide wire is laid on a slope, it must be
laid at an angle across the slope. Refer to 3.6
Installation of Guide Wire page 28.
Free the robotic lawnmower and rectify the
reason for the lack of drive. If it is due to wet
grass, wait until the lawn has dried before using
the robotic lawnmower.
Dock the robotic lawnmower in the charging
station and check that the charging strips and
contact strips make good contact.
Remove the object.
Turn the robotic lawnmower the right way up.
Place the robotic lawnmower in the charging
station. This behavior is normal and no action is
required.
