1.3.2 Laying Out the Perimeter Wire
Start setting the perimeter wire by placing pegs every few meters and at the lawn corners according to
your plan; do not forget obstacles that need to be demarcated while laying the wire.
After removing enough wire within a given section, use the RoboRuler provided to set the correct distance
from the lawn edge. The RoboRuler is used to help position the perimeter wire along walls, fences,
sidewalk, driveways, flowerbeds and other perimeter zones.
There are two basic measurements that are used on the RoboRuler (Figure 1.12).
The shorter distance
is used along perimeter edges where the area outside the immediate perimeter is
free of obstacles and is the same relative height as the perimeter edge or lower (sidewalk on the same
level or flowerbeds).
The longer distance
is used along perimeter edges where the area outside the immediate perimeter has
obstacles or differences in the height along the perimeter edge (walls and fences).
Important
If the lawn's edge borders with a pond, swimming pool or watercourse or where the grass level is higher
than 70cm (2ft) from the edge around it, then it is required to keep a distance of at least 1.2m (4ft)
between the wire and the water (or chasm) otherwise supplement a fence or the same along the lawn's
edge, so Robomow can detect it. The height must then be at least 15cm (6 inch). This will prevent
Robomow, under any circumstances, from crossing the wire outside the working area
1.3.3 Fastening The Wire To The Ground
It is not necessary to bury the perimeter wire, though you may do so if you wish, up to 10 cm
(4 inches) deep.
Small pegs or stakes are supplied with the Robomow and they are used to fasten and hold the
perimeter wire to the ground, below grass level.
Initially place a minimum number of pegs to fasten the wire down. Remember that you will want to test
the wire set up before you fill in additional pegs and you may find some areas where you will need to
move the wire position slightly.
Upon hammering the peg to its final depth in the ground, pull the wire tight. It is a lot easier to insert
pegs into wet soil. If the soil is dry, water the yard before perimeter wire set up.
WARNING!
Damage to the eye is possible. Use proper eye protection and wear
appropriate work gloves when hammering the pegs. Hard or dry ground
may cause pegs to break when driving them in. In extreme cases,
watering the lawn where the pegs will be driven can be beneficial.
