7.3.1.2 Green flashing light
ECO mode is enabled in the product and no loop signals
are therefore being transmitted in the loop wires. If the
product has been removed from the charging station
manually without pushing STOP before, ECO mode may
still be enabled (green flashing light) so that the loop
system is not transmitting any signals. To start the loop
system manually:
1. Place the product in the charging station and push
the STOP button.
7.3.1.3 Blue flashing light
A blue flashing light is most likely a break in the
boundary loop.
1. Check the connections to the charging station.
2. Disconnect all cables from the charging station.
3. Measure the resistance in the boundary wire using a
multimeter. The resistance value for a non-faulty
boundary wire should be between 0-20 Ohm.
•
Value >20 Ohm: Indicates a break in the boundary
loop. Identify and repair the break. Refer to
Boundary loop on page 6 .
•
Value <20 Ohm: Indicates that the boundary loop is
intact. Replace connectors to the charging station.
Replace the circuit board in the charging station if
the fault remains. Refer to
tower on page 20 .
7.3.1.4 Yellow flashing light
A yellow flashing light indicates malfunction in the guide
wire.
1. Check that the guide wire connector is properly
connected to the charging station.
2. Replace the guide connector.
3. Break in the guide wire: Find out where the break is.
Replace the damaged section of the guide wire and
splice the ends using an original coupler.
7.3.1.5 Red flashing light
A red flashing light is most likely an interruption in the F-
wire in the charging station's antenna.
1. Replace the charging tower. Refer to
charging tower on page 20 .

7.3.1.6 Solid red light
A solid red light is probably a fault in the circuit board, or
an incorrect power supply in the charging station.
1. Check the power supply.
2. Replace the charging tower. Refer to
charging tower on page 20 .
7.4 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.
7.5 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.
7.5.1 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 emty the product stops. The
result of the battery test is then saved automatically
and can be found in Autocheck.
7.5.2 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
