on page 23 andsee chapter 4.5 "Connecting tubes", page 24.
– If necessary, also remove the rim protecting ring.
– Loosen and remove two wheel nuts positioned next to each other near to the
valve.

PA tube and the valve.
The PA tube should be able to be guided to the tire valve without stretching,
upsetting deformation or twisting.
