The following are general rules:
Higher air pressure: Low rolling resistance / less suspension comfort
Lower air pressure: Higher rolling resistance / more suspension comfort
See point 7.5 for sizes and air pressure for the guide and rear wheels.
4.1 Rear wheels with drum brake
The drum brake allows safe braking, which is independent of the tyre pres-
sure. It is activated with the brake lever on the right and left push bar with
four engagement options. A safety catch engages with an audible „click“
by pulling the lever. The brake is applied in the fourth click position. Release
the brake by pulling the lever again and pressing the red safety catch at the
same time. By braking lightly on one side it is possible to achieve a steering
movement when pushing.
Setting the drum brakes
The drum brakes are set by turning the
setting screws (
A ) in or out. They are
located at the lower end of the brake
cable in the brake saddle. Unscrew the
screw a little for precise adjustment un-
til you hear a grinding noise with tur-
ning the rear wheel. The brake jaws are
placed lightly against the hub housing
in this state. Then turn the setting screw
1 turn back and clamp it in place with
the nut. Check the function of the drum brake and readjust the setting screw
if necessary.
Leave this work to your specialist dealer in case of any uncertainty.
The drum brake may only be used on the level with maximum load as a par-
king brake due to safety reasons. The knee lever brake must always be used
on a slope and tilt up to a maximum of 8%.
