3. Remove the wheel brake including the Bowden cables and replace if required.
Properly reassemble all components upon completion of the work.

6.6.2 Setting/Adjusting the Brake Release

The Bowden cables are normally adjusted on the brake release housing. If the correct setting
cannot be obtained by means of the adjustment screw, the threaded rod on the other end of the
Bowden cable can be moved by approximately 5 – 8 mm on the drive motor side. Subsequently,
the brake release must be completely readjusted. When making adjustments for the first time
(e.g. cable replacement), the Bowden cable should have very little play before adjusting it.
Tools:
❒ 2 open-end or combination wrenches, size 7, to establish the setting
❒ 2 open-end or combination wrenches, size 8, to make adjustments
INFORMATION
Lock the adjustment screw every time the setting is changed. Otto Bock recommends making adjust-
ments in small increments (½ turn).

Steps:
1. Loosen the M5 counter nut (SW 8) and turn the adjustment screw clockwise on the brake
release housing.
2. Commence functionality check from the beginning.
b) Adjusting a slack Bowden cable
Steps:
1. Loosen the M5 counter nut (SW 8) and turn the adjustment screw counter-clockwise on the
