Ensure Compatibility:
The bicycle tube must only be used for the intended wheel sizes and tire pressures.
Installation Instructions:
When installing, ensure that the tube is correctly seated in the tire and is not twisted.
Place the valve correctly to avoid damage during inflation.
Also, ensure even distribution of the tube in the tire to prevent pressure points and resulting damages.
Operating Instructions: Do not exceed the recommended tire pressure range, as this may cause the tube to burst. After significant impacts (e.g., potholes), check the tube for potential damages.
Warnings:
A damaged or worn tube must not be used.
High temperatures, such as those caused by extreme sunlight or in vehicles during summer, can damage the tube and lead to bursting.
Replacement in Case of Wear: Regularly check the tube for wear or damage. If you notice wear, uneven abrasion, cracks, or damages, replace the tube immediately.
