8.3 Repair
8.3.1 Inner tube, rim tape and tyre replacement
CAUTION
Improper tyre replacement
Injuries to the user due to incorrect installation, product damage
f
No person is permitted to sit in the wheelchair during tyre replacement�
f
Before removing a wheel, support the product so it cannot tip over�
f
Always replace the tyres in pairs� Two differently worn tyres affect the directional stability of the wheelchair�
INFORMATION
Tubeless TUFO indoor sport tyres can be ordered as an option for this wheelchair type� They have to be replaced
entirely in case of damage�
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�
