CAUSE
◾
The mower is overloaded.
◾
The mower deck is clogged with grass and debris.
◾
The mower is overheated.
◾
The battery pack(s) in the mower's battery
compartment is overheated, resulting in combined
Ah rating of all inserted batteries to be below
15Ah.
◾
The mower is in Limp-Home mode.
◾
The mower is hit by a foreign object, resulting in
motor self-protection.
◾
The mower is in Limp-home mode and the blades
are not turned off.
◾
The mower stops driving on a slope and the
operator is off the seat without setting the
parking-brake pedal at the braking position.
◾
When the mower is turned off on level ground
without removing the battery pack(s) from
the mower, the battery indicators will remain
illuminated for 60 minutes.
◾
When the mower is turned off on a slope without
setting the parking-brake at the braking position,
the battery indicators will keep on until the battery
charge is depleted. The audio indicator keeps

SOLUTION
◾
Raise the deck cutting height or slow down the driving
speed to reduce the load of the mower.
◾
Clean the mower deck and make certain that the
blades have freedom of movement.
◾
Reduce the load of the mower, by raising the deck
cutting height or slowing down the blade/driving
speed 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 battery compartments.
3. Reduce the load of the mower by raising the deck
cutting height or slowing down the mowing when
resuming operation.
◾
When the mower is in Limp - Home mode, the blades
are automatically switched into low rotation speed.
The operator should stop working and drive to the
battery charging area as soon as possible.
◾
Push the PTO switch down and then up to restart the
blade motors.
◾
Push the PTO switch down to turn off the blade
motors. The audio indicator will stop sounding when
the blade motors are turned off.
◾
Set the parking-brake pedal in the braking position
before leaving the mower on the slope.
◾
No action is needed. The battery indicators will go off
after 60 minutes has passed.
◾
Set the parking-brake pedal in the braking position
before leaving the mower on the slope.
