and clean it.
2. Check the float (2300/2) for damaged surfaces
and sealing areas (arrow).
3. Weight float (2300/2): Specified weight: max. 12 g.
4. For exceeded specified weight: replace the entire
casing ventilation (2300).
5. Check the sealing edge of the radial shaft sealing
ring (arrow) in the valve insert (2300/1):
-
For this purpose, place the float (2300/2) on a
suitable object (e.g. hex head nut).
