6.7 Finding breaks in the loop wire
Breaks in the loop wire are usually the result of
unintentional physical damage to the wire such
as when gardening with a shovel. In countries
with ground frost, also sharp stones that move in
the ground can damage the wire. Breaks can
also occur due to the wire being stretched
excessively during installation.
Mowing the grass too low right after the
installation can damage wire insulation. Damage
to the insulation may not cause disruptions until
several weeks or months later.
CAUTION: Always select the
maximum cutting height the first weeks
after installation and then lower the
height one step at a time every second
week until the desired cutting height
has been reached.
A defective splicing of the loop wire can also lead
to disruptions several weeks after the splice was
done. A faulty splice can, for example, be the
result of the original coupler not being pressed
together hard enough with a pair of pliers, or that
a coupler of lower quality than the original
coupler has been used.
Note: Please first check all known splices before
further troubleshooting is done.
A wire break can be located by gradually halving
the distance of the loop where the break may
