7.2 Repair7.2.1 Inner tube/rim tape/tyre replacement

INFORMATIONWhen driving outdoors, always carry a repair kit and tyre pump (when using pneumatic tyres) in case of emergency. 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 minimal technical skills. Users may change tyres themselves if they wish:

Removal and Preparing for Installation1) 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.

73 74

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 Tyre1) 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.4) Insert the tube into the tyre. 5) Mount the other side of the tyre on the rim, starting from the position across the valve. Ensure that the tube is

not pinched between the tyre and rim during this process.

Ottobock | 37discovery tmax

Maintenance/Repair

75 76

Inflating the Tube1) Ensure that the valve is positioned perpendicularly for proper positioning of the tube and tyre in the region of

the valve. 2) Firmly screw on the valve nut.3) Inflate the tube so that the tyre can still be pressed in easily with your thumb.

INFORMATION: If the circumferential lines on the two sides of the tyre are both at an even distancefrom the rim, the tyre is centred. If not, let some air out and realign the tyre.

4) Inflate the tube to the maximum pressure specified by the tyre manufacturer (see information printed on thecasing).

5) Firmly screw the valve cap onto the valve.

7.2.2 Special Case of Wheels with PU TyresIf the PU tyres have to be replaced, the entire wheel also has to be replaced on both sides (in pairs).
