Solution
Insert the safety key then press and
hold the START/STOP button for more
than 3 seconds to turn on the mower.
Have repairs performed by a qualified
service technician.
No action is needed. The mower can
continue working if the combined
battery Ah rating, over-current battery
excluded, is equal to or more than
15Ah. Once the over-current battery
returns to normal, it will join in power-
ing the mower immediately and the
icon will disappear.
In order to start this mower, EGO
batteries totaling 15Ah (2 X BA4200/
BA4200T) or more are required. For
best performance, we recommend
use of EGO batteries that total 30Ah
or more.
Raise the deck cutting height or slow
the driving speed to reduce the load of
the mower.
Clean the side discharge chute after
each use.
