... And the manual is not done well in this regard! My advice: 1 / drill with a small hole in the forest which the valve is put in position 2 / to empty once with the bell of the Takaje, then immediately press the valve to keep it down 3 / repeat until the valve does not release more than empty (listen closely if there is a whistle).
Depending on the containers, they keep the empty more or less time. The must is the combination with wiss familia at Le Parfait (it pierces the metal seal, vacuum and then press on the valve by screwing the cover) !!!!!!
