Using the one-hand brake, you have a parking brake which you can
use to brake both drive wheels using a brake lever.
The option can be fitted left or right.

| Lightweight wheelchair
Never use the brake lever as a support - e.g. when
transferring or standing up -, otherwise there is a
risk of tipping over and falling! The lever could
break off!
The parking brake - with or without brake lever
extension - only works on one drive wheel and
must therefore always be used on both sides!

4.13. Drum brake (optional)

The drum brake does not replace
the parking brake.
Adjusting the brakes must only be carried out by
trained personnel. Please bear in mind that if
the brakes are set incorrectly this can have life-
threatening consequences.
As an option, the wheelchair can be fitted with a drum brake which can
only be operated by an attendant using the brake lever on the push
handles (Fig. 27).
Adjusting the drum brake
Basic setup for the drum brake is carried out on the cable clamping
screw. Fine adjustment is carried out using the adjusting nut on the
brake cable. Unscrewing the adjustment nut will increase the braking
effect (Fig. 28).
• Drum brakes only work on one drive wheel at a time!
• Drum brakes are also subject to natural wear. If the braking effect
decreases, the wheelchair must no longer be used. In order to avoid
this happening, for your own safety you should check that the
brakes are working properly each time before setting off!
• Once you have finished the adjustment, re-tighten all screws and
carry out a brake test!

4.14. Backrest

In order to ensure a comfortable seating position, the rigidity
of the back sling can be adjusted. You can also adjust the backrest
height.
