62
56-VOLT LITHIUM-ION ELECTRIC ZERO TURN MOWER — ZT4200L/ZT4200L-FC
CAUSE
◾
The combined Ah of the inserted batteries is less
than 15Ah.
◾
The PTO switch is not pushed down when the
mower is stopped last time.
◾
The mower is overloaded at the moment the
blades starting, resulting in motor self-protection.
◾
Under extreme cold weather, the blade motor may
not start successfully due to the low temperature
protection.
◾
The blade interferes with the deformed mower
deck
◾
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 a foreign object, resulting in
motor self-protection.
SOLUTION
◾
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.
◾
Push the PTO switch downward and restart the
mower's blades.
◾
Start the mower grass cutting in lower blade speed
first and until the blades are getting successed
rotation, do not accelerate the blade speed as needed.
◾
Always store the mower and battery in warm
environment. Restart the mower when it is warmed
up. Please do not make repeated attempts under
extreme cold weather which may damage the
machine. Recommended operating temperature is
32°F–104°F (0°C–40°C).
◾
Call EGO Customer Service Center
◾
Raise the deck cutting height or slowing 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
without grass cutting. The operator should stop
working and drive to the battery charging area as
soon as possible.
◾
Push the PTO switch downward and restart the
mower blades.
