9 9
Probable Cause/Event
The time between operations is too long
because of long inactive time windows.
Grass is growing very fast.
The shape of the lawn is complicated (Narrow
Passages, obstacle and islands).
The set area is smaller than the actual lawn size.
Wrong clock time is set in the mower.
Rain Sensor is disabled or its sensitivity is set
too low.
The Islands feature is set to on. In this case the
unit is searching for the base by moving around
the lawn. This special search method takes
more time, and may create an impression that
the unit is still mowing, while in fact it is already
searching for the Base Station.
The Extension Cable is disconnected or
damaged between Power Box and the Base
Station.
Perimeter Wire is cut.
Poor connections
Twisted cables or a screw terminal which is
insulated with insulation tape is not a
satisfactory splice.
Soil moisture causes the conductors to oxidize.
