2.4 Removing the wheels
Generally, the twion wheels will remain on your wheelchair. If they need to be removed
(for example, for transport purposes), please proceed as follows:
• Switch the twion wheels off if you have not already done so (see chapter 2.3).
• When using Alber anti-tippers:
raise your wheelchair as described in chapter 8.2, and activate the anti-tippers.
• Press the locking mechanism [3] located at the centre of the wheel hub and carefully
pull the twion wheel off of the wheelchair.
• Once both wheels have been removed you can replace the anti-tippers to their ori-
ginal position, as described in chapter 8.2.
•
Without Alber anti-tippers:
lift your wheelchair by its push handles.
• Press the locking mechanism [3] located at the centre of the wheel hub and carefully
pull the twion wheel off of the wheelchair.
When removing a twion wheel never pull on its push rim [4]. This
could damage the fitted sensors.
Instead, hold the twion wheel by its tyre or the wheel hub when
removing.
Detaching the stub axle (if necessary)
If the twion wheels are stored laying on their rear side, the stub axles [6] protrude above
the wheel hub by a few centimetres. We therefore recommend taking the stub axles out
of the wheel entirely, to prevent any possible damage.
• Hold the stub axle [6] between your index and middle finger as shown in the diagram,
and press the locking mechanism [3] with your thumb.
• Pull the stub axle [6] out of the wheel hub and put it down.
Inserting the stub axle
If the stub axles have been taken out of the wheel as described above, they need to be
reinserted in the wheel hubs before you next attach wheels to your wheelchair.
• Hold the stub axle [6] between your index and middle finger as shown in the diagram,
and press the locking mechanism [3] with your thumb.
• Insert the stub axle [6] into the wheel hub.
Only insert the supplied stub axles into the twion wheels.
Do not use the stub axles of the manual wheelchair wheels because
when used with the twion wheels these do not have the necessary
length to ensure a secure fit in the brackets [7].
