Warning and safety instructions

-Store the butyl tube in a place protected from light
-Make sure that the tube is not trapped between the tire and the rim during assembly.
-Use suitable plastic tire levers
-Do not allow the tube to come into contact with solvents such as Acteon etc.
-Only use the tube in tires of the approved size
-Always install the tube with talcum powder so that it can settle in the tire without creases.
-After assembly and before inflating, check that the valve insert is firmly seated in the valve stem.
-When assembling on the move, make sure that no foreign objects such as sand or stones get into the tire when inserting the tube.
This is particularly true for velomobiles, in which fine sand and dirt often accumulate in the wheel house. This can lead to chafing between the tire and the tube and the tube can react prematurely with a loss of pressure.
