To avoid the wheelchair tipping backward, we recommend that
the wheelchair should be equipped with an antitipper (see
Chapter 4).
Please note that a heavy backpack fixed to the backrest can
affect the tipping behaviour of the wheelchair.
The position of the seat module influences the balance and the
tipping tendency of the wheelchair. The centre of gravity must be
re-defined after adjustments have been made.

Driving over stairs and steps
Always be very careful and move slowly when driving
over curbstones, stairs or other steps.
Do not try to drive over steps which have a height of more
than 25 cm.
Only drive on stairs with more than one step if an aide is
behind the wheelchair.

Driving down a step
Drive to the edge of the step, make sure that the wheelchair
is in a straight position.
Hold on to the two push handles on the rear of the
wheelchair and tilt backward so that the front wheels leave
the ground.
Hold the wheelchair in this position and push it down the
step slowly. The wheelchair driver can support you by using
the hand rims.
