result. The robotic lawnmower can also mow in the rain,
however wet grass easily sticks on the robotic
lawnmower and there is a greater risk of slipping on
steep slopes.
The blades must be in good condition to obtain the best
mowing result. In order to keep the blades sharp for as
long as possible it is important to keep the lawn free
from branches, small stones and other objects.
Replace the blades regularly for the best mowing result.

1.2.3 Working method
The robotic lawnmower automatically mows the lawn. It
continuously alternates between mowing and charging.
When the robotic lawnmower body hits an obstacle or
approaches the boundary wire the robotic lawnmower
reverses and selects a new direction. Sensors at the
front and back will sense when the robotic lawnmower is
approaching the boundary wire. The front of the robotic
lawnmower always passes the boundary wire by a
specific distance before the mower turns around. The
distance can be changed to adapt to the installation if
required.
The STOP button on the top of the robotic lawnmower is
mainly used to stop the robotic lawnmower when it's
running. When the STOP button is pressed a hatch
opens, behind which there is a control panel. The control
panel is where you manage all the robotic lawnmower

settings.The STOP button remains pressed in until the
hatch is closed again. This together with the START
button acts as a start inhibitor.
1.2.4 Movement pattern
The movement pattern of the robotic lawnmower is
random, which means that a movement pattern is never
repeated. With this cutting system the lawn is mown
evenly without any mowing lines from the robotic
lawnmower.
1.2.5 Finding the charging station
The robotic lawnmower can be set to search for the
charging station in up to 3 different ways. The robotic
lawnmower automatically combines these 3 search
methods to locate the charging station as fast as
possible but also to avoid as much tracks forming as
possible.
Using the manual settings options the 3 search methods
can be combined to optimize the search for the charging
station for the shape of the garden in question, see
Installation on page 28 .
1.2.5.1 Search method 1 - Irregular
The robotic lawnmower operates irregularly until it gets
close to the charging station.
The benefit with this search method is that there is no
risk of tracks on the lawn from the robotic lawnmower.
The disadvantage is that search times can be somewhat
long.
