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

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!
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.

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!

4.13. 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.

4.13.1. Back sling

The more taut the back sling, the more rigid the backrest will feel. First
remove the back cushion which is fixed in place with a hook and loop
fastener. You can then change the tension of the individual straps so
that they are more or less taut. In order to relieve tension on certain
areas of your back, you can make the straps there slightly looser. You
must now refix the back padded cover with the hook and loop fastener.

4.13.2. Backrest height

In order to be able to adjust the backrest height, we recommend
removing the sideguards and back padded cover first. You can then
undo the screw fitting on both sides (Fig. 29) and move the frame to
the required height. Then refit the screws in the recesses provided for
this purpose and tighten them by hand.

4.14. Push handles

The height of the push handles can be adjusted to make it more
comfortable for the attendant. Undo the lever screw (Fig. 30) on the
push handle and move to the required height. Then re-tighten the lever
screw to lock the push handle in place.

4.15. Tipping aids

In order to make it easier for an attendant to negotiate obstacles such
as kerb edges, tipping aids can be used. Hold the wheelchair firmly
with both hands on the push handles. Press one foot onto one of the
tipping aids and at the same time push the hands down (Fig. 31).
Tipping may be restricted by the anti-tip wheels.
