Changing The Wheelbase; Setting The Wheel Camber And Toe-In - Otto Bock Motus Bedienungsanleitung

6.2 Changing the Wheelbase (Fig. 34)
Shifting the rear wheel backwards lengthens the wheelbase and thus provides for greater sta-
bility of the wheelchair. Shifting the rear wheel forwards (only for advanced wheelchair drivers!)
relieves the load on the casters. This increases the maneuverability of the wheelchair. The caster
wheels can then also be lifted more easily to clear obstacles such as curbs or steps.

The distance between rear wheel and side panel can be continuously adjusted by adjusting the
counter nut on the outer side of the rear wheel adapter.
When changing the adjustments originally made in the factory, two other component groups of
the wheelchair must be readjusted, refer to Chapters 6.3 and 6.4.
