- Mowing motor has faced over-
current conditions for too long as a
result of high grass or an obstacle
that is stuck or wrapped around
the blade.
- Something is preventing a blade
from rotating freely (Accumulated
grass clippings under the mowing

Corrective Actions
- Make sure the Base Station is connected to
the mains supply.
- Disconnect the Power Box from the mains
power and reconnect after 10 seconds.
- Check that the low voltage cable between
the Power Box and the Base Station is
connected.
- Check the LED indications on the Power
Box.
- Check the connection of the Perimeter Wire
to the Base Station / Perimeter Switch.
- Check the installation for cut wire. Repair
broken cable with the waterproofed
connector supplied in the box.
- Confirm Power Box is plugged into the
power outlet.
- Turn power on to the power outlet.
- Check the power outlet using another
appliance.
- Clean the contacts with a brush or piece of
cloth.
- Confirm a good connection of the Power
Box to the Base Station.
- CAUTION – Switch off the Safety Switch
before checking the blade.
- Inspect blade for foreign material or debris
preventing rotation.
- Clean out accumulated grass clippings using
a wooden stick.
- Check the drive wheels and remove the
grass or other objects.
- If Robomow has driven onto an obstacle,
Switch off the Safety Switch, raising the front
end: Remove or exclude the object from the
mowing area.
- If Robomow is being used on a slope too
steep for safe mowing, exclude this from the
mowing area.
- If high grass is preventing the front wheel
from fully turning on the ground, raise the
cutting height.
- If the ground contains large holes or
indentations where the front wheel can drop
into when passing across, fill these areas
with soil and level off.
