2.1 Installing the wheels
From a technical point of view, the stub axles [11] of the e-fix wheels are similar to the
stub axles of your usual manual wheelchair wheels. In this respect you can attach the
e-fix wheels to your wheelchair in the usual way.
• If you have not already done so, ensure that the system is switched off 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 catch [4] in the centre of the wheel hub (the coupling ring [5] must
not under any circumstances be turned at the same time) and push
- the stub axle [11] of the e-fix wheel into the wheel mount [13] and then
- the bushing [10] of the e-fix wheel into the torque plug [12].
The coupling ring [5] must not under any circumstances by turned
whilst pushing the release catch [4] as this can cause damage to the
wheel. The wheel can then no longer be removed.
The e-fix wheel must be engaged to attach it to the wheelchair.
• Check whether the e-fix wheel can be pulled out of the wheel receiver [13] without
pressing the releasing device [4]. If so, the e-fix wheel is not sitting correctly in the
wheel receiver [13] and needs to be inserted again as described previously.
• Attach the second e-fix wheel on the other side of the wheelchair.
• Check the colour displayed in the viewing panel [3] of the e-fix 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 needs to be moved manually.
• For more details regarding the operating modes, see chapter 6.
• To change the operating mode you need to rotate the coupling ring [5] by about 40
degrees around its axis until it stops.
In these few steps, you have attached the e-fix wheels to your wheelchair. To start
motorised travel you need to select the “green” operating mode on the e-fix wheel and
then switch on the system using the control unit (see chapter 5.2.1).
