Changing The Wheelbase - Otto Bock M1 Intro Bedienungsanleitung

A

6.2 Changing the wheelbase

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.
DANGER!
Please note: If the rear wheels are in a more forward position and the user's body is
not appropriately positioned, the user may tip backward - even on level ground!
DANGER!
For untrained wheelchair users and when there are extreme adjustments to the rear
wheel, an anti-tipper is strongly recommended!
DANGER!
For transfemoral amputees it is essential to shift the rear wheels backwards!
INFORMATION!
For Start M1 Intro, M2 Effect, M3 Hemi and M6 Junior: Loosen the screws A of the
rear wheel adapter (Fig. 24) at the frame and mount the rear wheel adapter (with
sides reversed) in the desired position. The distance between rear wheel and side
panel can be continuously adjusted by adjusting the counter nut on the outer side
of the frame.
INFORMATION!
Make sure to firmly retighten all screws and nuts after making adjustments. The
proper torque of the screw connection of the rear wheel adapter is 8 Nm.
INFORMATION!
For Start M4 XXL and M5 Comfort: Loosen and remove the 4 screw connections B
(Fig. 25) which connect the rear wheel adapter to the frame. The adapter can then
be shifted to the desired position on the frame tube and the plastic adapter.
