Solution
Reduce the load of the mower by rais-
ing the deck cutting height or slowing
down the blade/driving speed. Take a
break and allow the mower to cool.
Follow the instructions in the section
"COLD WEATHER OPERATION".
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 battery
compartments.
3. Reduce the load of the mower by
raising the deck cutting height or
slowing down the mowing when
resuming operation.
Stop working and return to the battery
charging area.
NOTE: When the mower is in Limp-
Home mode, the blades are automati-
cally switched into low rotation speed
and meanwhile the audio indicator will
keep beeping. The operator should
push the PTO switch downward to
turn off the blade motors. The audio
indicator will stop beeping after the
blades stop.
The mower will stop working imme-
diately. The operator should transport
the mower to the battery charging
area for charging.
