    1. Hello Renko,
      using the presta valve key is very simple.
      Just ft the key hole over the valve mechanism and turn counter-clockwise to unscrew it.
      Once the mechanism is removed, just make sure its rubber seal has no solid residue of latex (if so, take it away; if you cannot, just use a new valve mechanism).
      To reinstall the valve mechanism: fit the mechanism on the valve stem, then use the key to tighten it, this time turning clockwise. Et voila!
