Trouble shooting chart

Refer to "Sound and lamp indications" for explanations of the Auto Mower indications. Before trouble shooting, first charge the Auto
Mower battery in the charging station to eliminate faults due to low battery charge. Read through the entire Operator's Manual to
make sure that the fault cannot be easily solved by using the keypad commands or the power switch.

TROUBLE SHOOTING

Possible cause
The transformer is not connected to the
mains or its automatic fuse has tripped.
Break in the boundary wire.
If this only happens at certain places on
the lawn it may be caused by metal objects
(fencing, iron strengthening bars etc.) or
cables buried nearby.
If this happens near to an "island", it may
be because the boundary wire has been
laid in the wrong direction around the
"island" and is cancelling out its own signal.
Incorrectly adjusted docking unit. The
Mower charging pins do not make good
connection with the charging station
contact plates.
Auto Mower cannot find the search wire.
Break in the search wire.
Battery requires reconditioning.
Battery is worn out.
Action
• A continuous beep means that the search
and boundary wires are not broken.
• An series of beeps means incorrect
installation or a break in the search or
boundary wire. Ensure that the search and
boundary wires have been installed in
accordance with the installation instruc-
tions, or repair the break in the wire.
Use the test switch on the charging station to
check loop wires and power supply. Repair
the break in the loop wire using Husqvarna's
waterproof connector, part no. 535 0443-01.
Check by moving the position of the bound-
ary wire.
Ensure that the boundary wire has been laid
in accordance with the installation instruc-
tions.
• Use a fine abrasive cloth to clean the
surfaces of the charging pins and contact
plates.
• Make sure that the mower is standing on
flat ground and that neither of the rear
wheels is in a dip.
• Adjust the docking unit horizontally and
vertically.
• If necessary bend the contact plates down
slightly.
Change the route of the search wire so that it
goes into every part of the working area.
Check the wire by using the test switch as
described above.
The battery requires reconditioning. Place
the Auto Mower in the charging station and
enter 71 #. The battery will be recondi-
*
tioned automatically, which will take 6–10
hours. The mower will give its usual charging
signals during this time. When reconditioning is
complete the mower will return automatically to
normal operation. It is an advantage if the
battery is reconditioned at night when it is
cooler. If the problem persists, contact your
dealer for assistance.
Contact your dealer to get a replacement
battery.
