8.2.1 Inner tube, rim tape and tyre replacement

CAUTION
Improper tyre replacement
Injuries to the user due to incorrect installation, product damage
► No person is permitted to sit in the wheelchair during tyre replacement
► Before removing a wheel, support the product so it cannot tip over.
► Always replace the tyres in pairs. Two differently worn tyres affect the directional stability of the wheelchair.
INFORMATION
When driving outdoors, always carry a repair kit and tyre pump (when using pneumatic tyres) in case of emer­
gency.
Suitable tyre pumps are listed on the order form and are supplied with the product. An alternative is tyre foam,
which fills your tyre and then hardens (available from bicycle shops, etc.).
Repairing flat tyres requires only the necessary tools and users may change tyres themselves if they wish:
Removal and preparing for installation
1) Carefully remove the tyre from the rim using appropriate tools.
INFORMATION: Take care not to damage the rim or the inner tube.
2) Unscrew the valve nut from the valve and remove the tube.
3) Repair the tube according to the directions in the repair kit or replace it with a new tube.
4) Before fitting the tyre again, inspect the rim bed and tyre inner wall for foreign objects. This could have caused
the puncture.
5) Before installing the tube, check that the rim band is in proper condition. The rim band protects the tube from
being damaged by the ends of the spokes.

Replacing the rim band (only when necessary)
1) If the rim band needs to be replaced, remove it from the rim.
2) Install the new rim band on the inside of the rim, making sure the valve opening is in the right position.
3) Glue the rim band in place if this is intended. Ensure that all spoke ends are covered.
Installing the tube and tyre
1) Behind the valve, push one side of the tyre over the edge of the rim.
2) Slightly inflate the tube until it starts to assume its round shape.
3) Unscrew the valve nut from the tube and push the valve through the valve opening in the rim.
