Changing pneumatic tyres

CAUTION
• 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.
