performance.

screwed into the correct outlets. It should not be possible to unscrew them by hand
while the regulator is under pressure. Examine them closely along their entire length
to ensure that there are no kinks, twists or cuts. If they are fitted with hose protectors
do not forget to slide them back so that you can check underneath.
2 - Check the two corrugated hoses connected to the second stage and to the mouthpiece.
Verify that they are secured by the locking collars. Carefully check their condition along
their entire length to ensure that they are not twisted, cut, jammed or torn.
3 - Visually check that the outside of the 1st and 2nd stage is in good condition.
4 - Check that the mouthpiece is in good condition and has no cuts.
5 - Check that the two mouthpiece screw connections are correctly tightened. Do not
use any tools to tighten them.
6 - Ensure that the two lugs on the locking collars are aligned with the mouthpiece
(middle position). Starting from this middle position, you can adjust the position to meet
your personal preference.
