Robomow RM200 Operating & Safety Manual page 13

1.2.4
 Obstacles that are relatively rigid and higher than 15cm (6 inches), such as trees, phone poles and
power poles can be left in the lawn without any consideration during the wire setup. The Robomow
will turn when it collides with this type of obstacle.
 Other obstacles such as, flowerbeds, fountains and small trees, must be protected from the
Robomow using the perimeter wire. This is done as part of the setup process and is commonly
referred to as a perimeter island. However, for the most gentle and silent operation, it is preferable to
demarcate all fixed objects in the working area.
To create a perimeter island (Figure 1.8):
 Take the wire from the perimeter section closest to the obstacle;
 Peg it around the obstacle, using the RoboRuler short distance;
 Returning back to the same spot of the edge you started from;
 The wires leading to the perimeter island and coming back to the edge should be parallel and
touching BUT they cannot be crossed. The wires to and from the perimeter island can be secured
with the same pegs. The mower will not recognize these two wires and mow over them as if they do
not exist. The single wire around the perimeter island will be recognized and prevent the mower from
entering this area.
 Areas with obstacles grouped closely together should be covered by a single perimeter island or if
they are close to the edge of the lawn, leave them out of the designated area.
While the picture shows two
wires separate, they should
be adjacent and placed
under the same pegs
Caution! Setting the Perimeter Wire
counter-clockwise around the
obstacle will cause Robomow to
drive into the island".
1.2.5 Slopes
The Perimeter Wire should not be laid across a slope that is steeper than 15cm (6in) per distance of 1
meter/3.3ft (15%). There is a risk that Robomow will find it difficult to turn and might cross the wire outside,
especially in damp weather conditions, as the wheels can slip on the wet grass.
However, the perimeter wire can be laid across a slope steeper than 15% if there is an obstacle (fence,
wall or dense hedge) that can prevent Robomow from slipping out of the area.
The maximum slope limit Robomow can mow inside the working area is 33%, roughly equals to 33cm (1ft)
of rise per 1 meter (3ft). In any event, a slope that causes the front of the mower to raise from the ground
while climbing is too steep and should not be included as part of the cutting area (see area marked as 'B' in
Figure 1.9). Sloping area greater than 33% cannot be included in the working area.
