Scooter slow
The charge status of the batteries is low. Charge the
batteries as soon as possible.

Battery voltage is too low Driving is not
possible
The charge status of the batteries is empty. Charge
the batteries as soon as possible. Check the battery,
connections, and cables.
3
Battery voltage is too high Driving is not
possible
The charge status of the batteries is too high. Causes
can include excessive charging and/or descending a
hill (since in this case the batteries are automatically
charged). When descending a hill, reduce the speed
in order to not charge the battery further. Switch the
scooter off and back on.
4
Time limit for maximum
current limit exceeded or
control unit too hot
Driving is not
possible
The scooter has consumed too much current for an
overly long period of time, which could be attributed to
an excessive load, jamming, or the throttling of the motor.
Switch the scooter off and wait a few minutes before
switching it on again. The control unit has discovered a
short circuit in the motor. Check the cable harness for
short-circuited electrical circuits and check the motor.
Contact your customer service.

Check whether the gearshift lever for the parking brake

brake and the cables for short-circuited electrical circuits
or exposed cables. Contact your customer service.

Driving is not
possible
A STOP function is enabled or a charge blocking has
occurred. Disable the STOP function and separate the
charging unit from the scooter. Bring the control lever
into a neutral position and switch the scooter off and
back on. The control lever may need to be recalibrated.
Check the cables of the control lever.
