Changing pneumatic tyres
Risk of injuries and damage
•
Make sure all air is released from the tyre, before removing it.
•
Make sure that no body parts, the inner tube nor any other objects are pinched
between tyre and rim.
•
Make sure all screws are firmly secured by hand before driving with the wheelchair.
•
Make sure that the pressure is correct, see the pressure indication on the tyres.
•
Inflate the tyre using inflating equipment which complies to regulations and with a
pressure indication in “bar”.
•
Only use replacement parts approved by Vermeiren.
To change the tyre or inner tube, proceed as follows:
1. Let all the air out of the inner tube.
2. Insert a tyre lever between de tyre and the rim.
3. Gently push the tyre lever downwards. This will pull the tyre over the edge of the
rim.
4. Move the lever along the rim so the tyre pops out.
5. Carefully remove the tyre from the rim and remove the tube.
Place the rim belt in position over the air valve before inserting it into the
rim. The rim belt can now be pulled over easily. Check that all spoke heads
are covered (a rim belt is not required in the case of a plastic rim).
Push the tyre over the edge of the rim, starting behind the air valve. Inflate
the tube slightly until it is round, and place it inside the tyre.
If the tube fits inside the tyre without any folds (in case of folds: let out some
air), then the upper side of the tyre can be pressed lightly onto the rim with
both hands, starting at the air valve. Lightly push the air valve inwards and
pull it out again to make sure that the tyre is positioned properly in the region
of the air valve.
