Sensors
Obstacle/contact sensor:
When the robot mower meets an obstacle, it will
reverse and change direction to avoid the obstacle.
If it does not find a new way within 3 seconds, the
cutting motor stops. If it does not find a new way
within 10 seconds, the robot will shut down and it
will require a manual restart to get it running again.
Rain sensor:
In case of heavy rain, the robot will automatically
return to the docking station and restart cutting
when the next working cycle begins. Raindrops
from overhanging branches may activate the rain
sensor, in which case the robot will return to the
docking station.
Lift sensor:
This sensor is placed close to the wheels and meas-
ures the gravity of the wheels.
If the robot is lifted manually or if both wheels run
into a hole, the robot will shut down and must be
restarted manually. Restart on the lawn can only
take place if you move the machine so that it has
a maximum distance of 2 meters to the boundary
wire and press "Same Area" button and "START".
The working cycle will not be changed.
Tilt sensor:
A 6-axle sensor is integrated in the robot mower to
measure the tilt angle in all directions. If the tilt an-
gle exceeds 30o, the cutting motor will stop imme-
diately, but continue driving. If the angle decreases
within 10 seconds, the cutting motor will restart au-
tomatically. If, however, the angle does not decease
within 10 seconds, the mower will shut down and
will need a manual restart.
Restart on the lawn can only take place if you move
the machine so that it has a maximum distance of 2
meters to the boundary wire and press "Same Area"
button and "START". The working cycle will not be
changed.

Maintenance and Winter Storage
Ordinary cleaning:
You p rolong the life of your robot mower if you currently keep it clean.
Top cover
Lift the top cover and cl ean it for grass and dirt using a soft brush. You can wipe it with a wet cloth (do not
rinse with water due to the electronics).
Bottom
Clean also the bottom using a soft brush. Particularly, ensure that blades, blade holder and f ront wheels can
in wet grass, it is important to ensure that the blades are cleaned for grass so that they can rotate.
Docking station
You shall also clean the docking s tation frequently by removing di rt and grass from the base pla te.
Switches
Clean the switches on the robot mower and the docking s tation with fine emery paper or s teel wool a couple
of times during the season. Clean the two cha rging tentacles of station.
It is important to make sure that all bolts, screws and nuts are fastened
correctly at all times to give the robot mower the best possible working
conditions.
Replacement of spare parts:
Blades:
The blades have 2 sharp -cut edges. Therefore, they are reversible if they
have become unsharp on one edge. If both edges are unsharp, the blades
can easily be replaced using a screwdrive r.
Note:
When you have taken out the screw, it is important to remove grass and other dirt f rom the blade holder.
Then you can insert the new blad e. Screw the blade screw firmly in. Check that the blades are rotating.
Note: It is important that all 3 blades are reversed or replaced at one time.
Battery:
Gene rally, the battery life is 5 years, depending on the workload and main tenance of the robot mower.
You can easily replace the battery by unfastening the 4 screws in the battery compartment cover and re-
placing the old battery with a new on e.
Note: Always use original/authorized spare parts!
Winter storage:
Before winter storage, we recommend that you charge your robot mower in the docking station.
During the winter, we recommend that you take your robot mower and charging station inside and store
It is a good idea to charge the battery a couple of times during the winter to ensure good performance. You
can either do it by taking your docking station inside too or by putting your robot mower in to the docking
station outside and take it back inside after charging.
If there is any risk of frost in the room whe re you store your robot mower, you can take out the battery and
keep it in a warm and dry place.
