Installation Guide

Light Cause Action
Blue flashing light The boundary loop is not connected to the
charging station
Check that the boundary wire connector is fit-
ted properly to the charging station. See Con-
necting the boundary wire on page 18 .
Break in the boundary loop Find out where the break is. Replace the dam-
aged section of the boundary wire with a new
loop wire and splice using an original coupler.
See Finding breaks in the loop wire on page
43 .
Yellow flashing light The guide wire is not connected to the charging
station
Check that the guide wire connector is properly
connected to the charging station. See Laying
and connecting the guide wire on page 19
Break in the guide wire Find out where the break is. Replace the dam-
aged section of the guide wire with a new loop
wire and splice using an original coupler.
Red flashing light Interruption in the charging station’s antenna Contact your local McCULLOCH representa-
tive.
Solid blue light Weak signal as the boundary wire is too long.
Max length is 400 m.
No steps have to be taken if the robotic lawn-
mower operates as expected.
Shorten the boundary wire by reducing the
working area or replacing islands with barriers
the robotic lawnmower can collide with.
Solid red light Fault in the circuit board or incorrect power
supply in the charging station. The fault should
be rectified by an authorized service technician.
Contact your local McCULLOCH representa-
tive.
Symptoms
If your robotic lawnmower does not work as expected, follow the troubleshooting guide below.
There is a FAQ (Frequently Asked Questions) on www.mcculloch.com which provides more detailed answers to a num-
ber of standard questions. Contact your local McCULLOCH representative if you still cannot find the reason for the fault.
Symptoms Cause Action
The robotic lawnmow-
er has difficulty dock-
ing.
The boundary wire is not laid in a long straight
line that is far enough out from the charging
station.
Check that the charging station has been in-
stalled according to the instructions in Laying
the boundary wire on page 17
The guide wire is not inserted in the slot at the
bottom of the charging station.
It is absolutely critical for operation that the
guide wire is perfectly straight and is in the cor-
rect position under the charging station. There-
fore make sure that the guide wire is always in
its slot in the charging station. See Laying and
connecting the guide wire on page 19 .
The charging station is on a slope. Place the charging station on a surface that is
entirely level. See Charging station on page 10 .
