Caster Wheels - Otto Bock M1 Intro Instructions For Use Manual

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.
When changing the adjustments originally made in the factory, two other component groups of
the wheelchair must be readjusted, refer to sections 6.3 and 6.4.

6.3 Caster wheels

Adjusting the caster wheel journal angle
After the rear wheels have been mounted in the appropriate position, the caster wheel journal
angle must be readjusted.
The threaded axle should be as horizontal as possible in relation to the ground to ensure optimal
driving behavior of the wheelchair. The caster adapter allows for continuous angle adjustment.
