6. Laying boundary wire
Read the entire section before starting work!
The laying of the boundary wire is the most important thing during installation, since proper
cable laying gives a more satisfactory result.
The robot lawn mower cannot cut all the way to the edge due to safety requirements
(distance from the cutting deck to the blades). You should therefore be aware, that an
edge of grass is left all the way around the lawn, which cannot be cut by the robot lawn
mower. Here you have to cut the grass with a grass trimmer or a regular lawn mower,
when needed. Alternatively, you can lay a wide tile edge (at least 12 cm) all the way
around the lawn at the same level as the grass, which the robot can drive on. Then you
avoid a grass edge that cannot be cut. See section "Cutting along tiles"
Ideally, you want this uncut grass edge as small as possible, and therefore the boundary
wire should be placed as close to the edge as possible.
Under optimal conditions, a distance of 20 cm will be ideal, but it requires some conditions
to be met:
The lawn must be flat along the edges so that the robot cannot slip in wet conditions
Flowers, plants, and branches should not hang low over the lawn
The wheels must not enter the soil bed while driving
Wheels and cutting deck must not come into contact with any obstacles
This means that the robot must be able to drive all the way around the boundary wire
unhindered without coming into contact with anything and not drive into the soil bed with
the wheels.
If the above cannot be met, it may be necessary to increase the distance. It depends on
the specific garden layout. It is recommended to have at least 1 cm extra distance, as the
boundary wire may shift slightly after some time when the grassroots grows.
If you make a change using the boundary wire (e.g., around a flower bed in the middle of
the lawn or an inground swimming pool / trampoline), then it is recommended to increase
the distance to 25-30 cm so that it does not risk falling.
Preparation:
First, find the cable reel and find the loose end. Next, find the wire pegs. Prepare a folding
ruler or a homemade distance ruler as a measuring stick of e.g., 20 cm long, so you can
easily make a consistent and correct distance to the grass edge / obstacles. In addition, a
hammer, a crimping pliers and a scissor / wire-cutter must be used to cut the wire (this is
not included).
Remember the grass must not be higher than 60 mm before starting work, otherwise
it must first be mowed with a regular lawn mower (with collection) first. It is
recommended that you cut the grass down to 35-40 mm before installing the robot.
Laying the boundary wire
Start the cable laying at the charging station and put a long part under the charging
station, which reaches about 50 cm further back, so there is plenty of cable to work with
when connecting the wire into the connectors on the charging station.
