All wheelchair users have expectations regarding wheelchair type, accessories, seating and

handling. Your Motus adaptive wheelchair offers many options that permit the wheelchair to be

adapted according to your requirements. We recommend consulting with your dealer or therapist

to determine which wheelchair settings will work best for you.

6.1 Adjusting Seat Height and Seat Inclination (Fig. 33)

The higher the rear wheel is attached to the frame, the more the seat inclines downward. This

has two effects:

•

First, the wheelchair has a greater tendency to tilt backwards.

•

Secondly, the user sits deeper in the wheelchair and thus has more stability.

A careful and synchronized height adjustment of both the rear wheels and the casters will allow

to adapt the seat height to the user's individual requirements.

The Motus offers the possibility to change vertical position of the rear wheel by shifting the rear

wheel adapter along the frame. Loosen all four screw connections (Fig. 33, see arrow) and

remove the screws. Shift the adapter to the desired position and firmly retighten the screws.

To achieve additional rear wheel positions, the rear wheel adapter can be turned by 180°.

When the rear wheel position is changed, the angle of the caster axle in relation to

INfORMATION

the ground also changes. Ensure that this angle is always approx. 90° wide (see Chapter 6.3).

The wheel lock must be re-adjusted as well (see Chapter 6.4).

Make sure to firmly retighten all screws and nuts after making adjustments. The proper

INfORMATION

torque for the screw connection of the rear wheel adapter is 8 Nm. The proper torque for the

screw connection of the fitting is 50 Nm�
