To Find A Break In The Boundary Loop; Battery Test - Husqvarna Automower 405X Workshop Manual

8.4 To find a break in the boundary loop

A break in the loop wire is normally due to physical
damage to the wire, e.g. using a spade while gardening.
In countries with ground frost, also sharp stones that
move in the ground can damage the wire. Breaks can
also be due to too high a tension in the wire during
installation.
Cutting the grass very short immediately after the
installation can damage the wire's insulation. Certain
damage to the insulation may not cause disruptions until
several weeks or months later. To avoid this, always
select the maximum cutting height the first week after
installation and then lower the height one to two steps at
a time every week until the desired cutting height has
been reached.
A wire break can be found by using a break detection
tool from the manufacturer or with the manual method
that is described in the Operator's manual.
The procedure involves 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.

8.5 Battery test

If the product's battery starts to perform poorly, the
product mows for shorter time periods. The product can

also stop and show the
Note: A battery test can be run on the workbench with
Autocheck, but the most reliable test result is achieved
when the product is run in an installation.
8.5.1 To do a battery test
1. Fully charge the battery.
2. Set the cutting height to maximum.
Note: The product must have a low level of cutting
resistance during the battery test.
3. Let the product to mow in manual operation mode
until the battery is empty.
4. When the battery is empty the product stops. The
result of the battery test is then saved automatically
and can be found in Autocheck or in the
menu .
8.5.2 To evaluate the battery test
A new battery has a total capacity of about 2100 mAh
but is charged to a maximum of 1700 mAh. The test
results from a battery test on a new battery are thus
normally around 1,600 to 1700 mAh.
As the battery ages the battery capacity decreases. If
the battery capacity displayed is approximately 1,000
mAh or lower, it is possible that the battery is poor and
needs to be replaced. The assessment should be based
on the most recently conducted test as the first test can
show an incorrect value. It is therefore more practical to
1582 - 001 - 23.12.2020
perform a battery test in connection with the product's
normal operation or in connection with it having recently
been in operation.
Note: The values are approximate and vary between
different products and batteries.
Note: If the product has not been in operation for more
than two months, at least two and preferably three
battery tests should be carried out.
