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.
