the product is at a standstill. This is not a ser-
vice brake which is suitable for reducing
speed.

, pull the brake lever back
up and rearwards again. In the open position,
the distance between the brake pin and the

25.1.2 Setting the brake
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
Settings on the brake could be necessary for
the following reasons:
You have changed the tyre or the tyre
pressure.
You have changed the wheel tracking or
the position of the drive wheels.
The brake is pulling unevenly or insuffi-
ciently after extended use.
To adjust the knee lever brake, proceed as
follows on both sides:
1. Initial situation: Drive wheels mounted on
the product and the knee lever brakes
open. The drive wheels have the specified
inflation pressure.
2. For the
correct positioning
of the knee
lever brake, slightly loosen the M5 fixing
screws (AF 4 mm) so that the knee lever
brake can be moved on the brake holding
rail.
