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
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 have occurred
until there is only a very short section of the wire left.
