Assembly on wheelchair
Before installing your trivida wheels, check
what axle holders your wheelchair has!
This works with the supplied quick-release
axles. Remove a wheel on your wheelchair. If the wheel
is secured with a quick-release axle, unlock the axle by
pressing the button at the end of the axle. Remove the
axle along with the wheel from the wheelchair. Test
with the new supplied quick-release axle to see
whether the diameter fits. If the axle sits firmly in the
bore hole, the axle holder diameter of your wheelchair
is 12 mm. If the axle wobbles in the bore hole, you have
a ½” holder or a non-standard dimension. In this case
you can replace the adapter bushing on the wheelchair
with the supplied bush. If the bush on your wheelchair
cannot be exchanged, please contact your medical
supply dealer or us.
If the diameter already fits, check the insertion length
of your bush. Insert the axle without wheel into the
assembly bush until the lock engages. You will notice
this when the button at the end of the axle returns to
the starting position. Now retract the axle as far as the
stop of the lock and mark the length of the exposed axle
with a marker. The measured distance must be 50 mm.
If this is the case, you can install the trivida wheels on
your wheelchair with the new quick-release axles
without any additional steps. In the case of different
lengths, please exchange the bush for the supplied
connectors. The bushes must be tightened to a torque
of 30-35 Nm. If it is not possible to install the supplied
quick-release axle bushes, please contact your medical
supply dealer or us.
When assembling the wheels ensure that
the lock of the quick-release axle is fully
engaged.
Only use your wheelchair when you are absolutely
certain that both wheels are securely mounted on the
wheelchair and the quick-release fasteners are
properly engaged.

Handling the trivida wheels
Wheel segments may only be removed
when both parking brakes of the
wheelchair are securely locked.
Please note that the braking effect of the parking
brakes may vary due to different wheel sizes. Before
using the trivida wheels for the first time ensure that
the brakes of your wheelchair are optimally adapted to
the wheel size. Observe all information and instructions
from your wheelchair manufacturer with regard to the
parking brakes.

Preparing for a transfer
Position yourself with your wheelchair beside the area
where you want to sit. Ensure that the parking brake is
applied on the side of the transfer just below a
separating edge of the trivida wheel. Maintain approx.
10 cm distance to the side in order to be able to open
the quick-release lever.
