The turn adjusters have a normal right hand

wise to fully closed (position zero [0]). Then,
turn counter clockwise to open, and count
the clicks until you reach the recommended
number of clicks. See Set-up data.
Do not use force, delicate sealing surfaces can
be damaged. Handtighten only.
Loosen the screw
...and adjust with
a C-spanner
... by turning the spring
