In general !
Since the drum brake is the most important safety device on your
wheelchair we recommend the use of a drum brake when an assisting
person is frequently pushing the wheelchair, the drum brake is optionally
available. Besides the drum brake allows deceleration.
At a drum brake the braking shoe does not effect the tire, but brakes
in the wheel hub, this braking system is largely independent of the tyre
condition (air pressure).
4.5.1. Drum brakes
Using the drum brakes by an accompanying person
The drum brake is operated by pulling both brake levers simultaneously
(Fig. 25). Remember that both sides must be pulled at the same time to
prevent the wheelchair from skewing sideways.
If you want to park the wheelchair, operate the brakes until the wheelchair
comes to a standstill. Then lock the knee lever parking brake (Fig. 22) to
25.
prevent the wheelchair from rolling away.

Adjustment of the drum brakes
The basic adjustment of the drum brake is carried out on the rope
clamping screw. The final adjustments are carried out with an adjusting
nut on the brake cable. If the adjusting nut is turned up, the braking
efficiency is increased.
• The drum brakes affect only one of the drive wheels at a time!
• Make sure that the drive wheels have the same air pressure to achieve
directional stability.

• Drum brakes get worn out as well. If the braking performance is redu-
ced, the wheelchair must be withdrawn from circulation. To avoid this
because of safety reasons your braking device should be checked by a
qualified mobility dealer every six months!
• After the adjustment are made, please tighten all the screws and
perform a brake test!
In general!
The adjustment of the brake system should be done only by a qualified
mobility dealer!
4.6. Seat height
There are 5 positions for tailoring the seat height to the user's
requirements. Driving wheel and steering wheel must be in the same
position in each case.
Adjustments of the seat height can affect the stability
of your wheelchair; a lower seat height has a positive
impact on stability.
