Locking The Steering Casters - Otto Bock B500 Instructions For Use Manual

A spring and shock absorber element on each of the two
steering casters increases driver comfort and improves
traction, especially on uneven surfaces.
The suspension effect is improved even more by a drive
wheel suspension.
If the power wheelchair is equipped with a drive wheel sus­
pension, then the batteries are stored in a drawer.

6.12.5 Locking the steering casters

The power wheelchair may be equipped with a steering
caster lock.
These serve to lock the steering casters in the forward dir­
ection, so that turning is no longer possible. Having the
power wheelchair drive in a perfectly straight line increases
safety when driving on ramps or using elevators.
Engaging the steering caster lock
► Push the folding lever on the front of the frame to the
side a bit until it disengages from the centre position.
