10. Use operating rod to open the vent valve . Fix it in place by inserting a

suitable fixing pin (

∅

4 mm) into the hole above the guide .

Pass connecting rod into the guide pipe of the bayonet base cap and
screw it into the connecting sleeve by turning it to the right until the
adjustment setting 30

1 mm is attained. Tighten lock nut , remove fixing

pin and close the vent valve .

Checking the adjustment
The square piece has to protrude 15 + 2 mm from the guide pipe.
It must be easily possible to push the complete operating rod assembly
(connecting rod and operating rod weigh approx. 8 kg) smoothly approx.
6 mm upwards (vent valve does not open yet, i. e. idle lift).

If this is not possible modify the adjustment setting in such a way that the
specified setting (15

mm) is maintained and the idle lift of the valve

0.5 mm) is also taken into account. Secure the bayonet base cap by

using hexagon-head bolts M8 x 40 and nuts M8 .
