Solution
Insert the safety key then press and
hold the START/STOP button for
more than 3 seconds to turn on the
mower.
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.
Reduce the load of the mower by
raising the deck cutting height or
slowing down the blade/driving
speed. Take a break and allow the
mower to cool.
1. The mower can continue working
if the combined battery Ah rating,
overheated battery excluded, is
equal to or more than 15Ah. Once
the overheated battery returns to
normal temperature, it will join in
powering the mower immediately.
2. If the combined battery Ah rating
is less than 15Ah, the mower will
not work until more battery packs
are inserted into the vacant bat-
tery compartments.
3. Reduce the load of the mower by
raising the deck cutting height or
slowing down the mowing when
resuming operation.
