6756-VOLT LITHIUM-ION ELECTRIC ZERO TURN MOWER — ZT4200S/ZT4200S-FC
PROBLEM CAUSE SOLUTION
The blades stop working
during grass cutting.
◾
The mower is overloaded.
◾
Raise the deck cutting height or slow down the driving
speed to reduce the load of the mower.
◾
The mower deck is clogged with grass and debris.
◾
Clean the mower deck and make certain that the
blades have freedom of movement.
◾
The mower is overheated.
◾
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.
◾
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.
◾
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.
