6. TROUBLESHOOTING
Cause
The guide wire is incorrectly
positioned in the charging
station.
The boundary wire is disturbing
the guide signal in the charging
station.
Dirt/leaves/grass have
accumulated in the charging
station and are preventing
the mower's charging strip
from making contact with the
charging station's charging strip.
The cables for the charging
strips in the mower are not
connected or connected
incorrectly.
The cables for the contact strips
in the charging station are not
connected or are connected
incorrectly.
The lawnmower cannot detect
the F field and therefore does
not turn in front of the charging
station.
Cause
Impaired battery capacity.

the Operator's Manual. If the boundary wire is
positioned along the left side of the charging
station it can affect the guide signal
