6. Brakes
6.1 The knee lever brake is a parking brake for blocking the wheels and may in no
circumstances be used for braking down the wheelchair’s speed!
Each wheelchair is equipped with two knee lever brakes. These
only have the purpose of blocking the wheels in their standstill
position. They are not designed for braking down the wheeling
chair. For this, your child should always use the grip rings and it is
also possible for you to deal with this, using the drum brake.
Please, keep in mind that strong friction will considerably heat
up the aluminium grip rings. For your child’s and your own
safety, always take care that the brakes are working perfectly.
Low air pressure, rainy and wet days, bad treads and a distance
too large between brakes and tyres, all may have an effect on
the functional performance of the brakes.
6.2 Knee lever brake - braked lockable (as option)
The same function as above, yet, in addition lockable by a
safety bolt. For securing the knee lever brake in braked-
state, lock the brake. The bolt will be interlocked as far as it
is not pulled out and turned by 90°. For releasing the brake
again, pull out the safety bolt and at the same time open
the brake.
6.3 Knee lever brake – braked and unbraked lockable (as option)
The same function as above, yet, in addition lockable by a red safety bolt in every
position. This bolt locks automatically in braked- or unbraked-state.
To actuate the brake, you only have to unburden the brake lever and pull the bolt
outwards to get the brake in the needed position. After that the bolt again locks
automatically and so it prevents a change of the brake position.
6.4 Brake lever lengthening (as option)
In case the brake is correctly adjusted but the operation lever
may no longer be reliably operated by manual power, in no
circumstances you may change the distance between brake
dowel and tyre! In this case, your child will need our brake lever
lengthening and your medical centre will be pleased to equip the
wheelchair with it. Please take care that your child is not sitting on
the lengthening – danger of breakage
