2.1 Installing the wheels
As described at the beginning, the two Esprit wheels [4] should remain on the wheelchair
at all times. However, if they have been removed, you must proceed as follows when you
re-attach them (with the help of an attendant if necessary):
• If you have not already done so, switch off the system at the control unit (see
chapter 5.2.2).
• Ensure that the wheel is engaged (see also the bottom left picture and the adjacent
explanations).
• Press the release mechanism [6] in the centre of the wheel hub (the coupling ring
[7]
must not, under any circumstances, be turned at the same time) and, at the
same time, push
- the stub axle [9] of the Esprit wheel into the wheel retainer [2] and
- the wheel plug [8] of the Esprit wheel into the wheel plug socket [3].
The coupling ring [7] must not, under any circumstances, be turned
while pressing the release mechanism [6] as this can cause damage
to the wheel. It is then no longer possible to remove the wheel.
The Esprit wheel must be engaged in order to attach it to the wheel-
chair.
•
Check whether the Esprit wheel can be pulled out of the wheel retainer [2] without
pressing the release mechanism [6]. If so, the Esprit wheel is not sitting correctly in
the wheel retainer [2] and needs to be inserted again as described above.
• Attach the second Esprit wheel on the other side of the wheelchair.
• Check the colour displayed in the viewing panel [5] of the Esprit wheel. The colours
green or red indicate the respective set operating mode. The following indications mean:
- green: The wheel is engaged; motorised operation is active.
- red: The wheel is disengaged; motorised operation is not possible. The wheel
must be moved manually.
• For more details regarding the operating modes, see subsequent chapters.
• To change the operating mode you need to rotate the coupling ring [7] by about
40 degrees around its axis until it stops.
In these few steps, you have attached the Esprit wheels to your wheelchair. To start
motorised travel you need to select the "green" operating mode on the Esprit wheel and
then switch on the system using the control unit (see chapter 5.2.1).
