3.3.5 Driving wheels
The driving wheels are mounted on a
fixed axle or a full floating axle, depend-
ing on the wheelchair model.
Note:
The tyre pressure is shown on both
sides of the tyre surface and can also
be found in the Technical data.
3.3.5.1 Full floating axle
The driving wheels can be installed or
removed without the need for tools (Fig.
30). Free the axle by pressing on the
rubber cap and pull outwards.
To install the driving wheels, free the
axle by pressing on the rubber cap (Fig.
30) and push the wheel into the axle
opening until it locks.
Warning:
Each time the wheels are installed,
!
test the locking mechanism by pull-
ing/pushing the driving wheel from
the side (Fig. 31).

– The full floating axle must be kept
clean. A functional fault may occur
in the case of contamination due to
sand or earth or in the event of freez-
ing of moist cold air.
– If the drive wheel has too much lat-
eral play or the full floating axle does
not lock, it should be repaired im-
mediately by an authorised ORTOPE-
DIA dealer.
3.3.5.2 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. 32/
) by approximately
one turn. Move the hand wheel to the
required position parallel to the driving
wheel. Tighten the fixing screws cross-
wise.
3.3.6 Brakes
The wheelchair can be halted via the
hand wheels, the toggle joint brakes
(Fig. 33) or the drum brakes (carers
only).
3.3.6.1 Safety information
The wheelchair must not be pushed
when the brakes are locked on.
If the braking effect reduces, the
wheelchair should be repaired immedi-
ately at an authorised repair centre.
In order to prevent unwanted swerv-
ing when stopping the wheelchair or
when locking the brakes on a sloping
surface, both brake levers should be ac-
tivated simultaneously.
