7.8 Wheel change
A wheel/tyre change requires technical
knowledge. You should therefore have
this work carried out by an authorised
workshop. Sitting in the wheelchair dur-
ing a wheel change is not permitted.
The wheelchair must stand on a level
and firm surface. Before starting the dis-
assembly work, support the frame to
prevent the wheelchair from tipping
over and secure it to prevent an un-
wanted movement or tipping over.
