3.2.11 Hand wheels
The distance between the hand wheels
and the driving wheels is adjustable. To
change this distance, loosen the four fix-
ing screws (fig. 48/
) by approximately
one turn. Move the hand wheel to the
required position parallel to the driving
wheel. Tighten the fixing screws cross-
wise.
3.2.12 Brakes
The wheelchair can be halted via the
hand wheels, the toggle joint brakes
(fig. 49) or the drum brakes (carers
only).

3.2.12.1 Safety information
The wheelchair must not be pushed
when the brakes are locked on.
If the braking effect reduces, the
wheelchair should be repaired im-
mediately at an authorised repair
centre.
In order to prevent unwanted swerv-
ing when stopping the wheelchair
or when locking the brakes on a slop-
ing surface, both brake levers should
be activated simultaneously.
Do not lean on the lateral brake le-
ver (fig. 49/
).
Attention:
!
The braking effect is dependent on:
– the condition of the tyres,
– the condition and fixing of the
brakes,
– the brake lever setting,
– the quality of the road surface.

3.2.12.2 Toggle joint brake
Activation of the toggle joint brake causes
a brake bolt to press on the tyre (fig.
50).
3.2.12.3 Drum brake
Activation of the drum brake causes
brake pads to press against the wheel
hub from the inside.
3.2.12.4 Service brake function
For measured braking, the lateral brake
levers of the toggle joint brakes (fig. 49/
) should be pushed forward slightly
and equally.
