Action/Check
Check all passages in the working area by positioning
the mower beyond the passage, seen in the direction
from the charging station, and press Home. If the mower
does not pass through the passage, change the Corridor
width setting via Garden - Follow loop – Corridor width
(shortcut 3-2-3).
Check that the charging station has been placed as set
out in the installation instructions.
Check the F-signal from the charging station: Place the
Automower in the test position and then check the value
via the Quick check function (Press and hold the 0 key
down for 2 seconds). The F-coil is defective if the value
for F is lower than 300. The charging plate must be
replaced.
Check the charging current from the charging station:
Place the Automower in the test position and then check
the value via the Quick check function (Press and hold
the 0 key down for 2 seconds). Contact is poor if the
current (I) is lower than 1.6 A. Now check the contact
strips on the charging station and charging strips and
charging cabling on the mower.
When the running time on the mower exceeds
3000 hours the battery is spent.
Let the Automower dock itself in the charging station by
pressing Home. Check that the charging strips and
contact strips make good contact. Also test the charging
current with the help of the Quick check function (press
and hold the 0 key down for 2 seconds). The current (I)
should be at least 1.6 A.
Check that the charging station does not lean to the side
and that the charging plate is not bent.
Check the cable lugs. File off any corrosion. Replace the
entire charging cable assembly if necessary.
Lift off the cover on the charging station and check the
connection.
Check that the contact strips on the charging station are
not jammed. Round off the charging strips on the
Automower if necessary using emery cloth and lubricate
with copper paste.
Check that the charging cable connectors and the
charging cables on the mower are undamaged.
Replace the control box. See page 108 to replace.
Remove the object.
Check that the contact strips on the charging station are
not jammed. Round off the charging strips on the
Automower if necessary using emery cloth and lubricate
with copper paste.
