CAUTION
Risk of accidents and injury due to lack of brake functionality. Incorrect brake settings can lead to
a loss of braking power. Repairs and settings must only be made by authorised personnel. Replace
damaged Bowden cables with new ones immediately.
Correct brake settings are essential for driving. This is why Otto Bock recommends inspecting
the brake every three months.
To avoid excessive friction, the radius of the Bowden cable must not be less than 10 cm.
Damaged Bowden cables must be replaced immediately, for example if individual wires are
protruding or there is a kink in the black sheath.
