Driving information
Avoid driving across an incline
(always try to drive in the direction of the incline / decline).
There is an increased danger of tipping
when climbing or descending gradients if:
the Scooter is loaded at the back and
additionally
the backrest (captain's seat) is leant towards the back and
the seat has been adjusted to its rear position.
You can achieve increased tipping safety if:
you adjust the seat in a more forward
position.
you adjust the backrest (captain's seat)
to be vertical
you lean your upper body slightly forwards
(see sketch)
