10 Tighten locknut (2) with SW 36, torque max. 40 Nm.
Note:
Take note for VEGAPULS 68 with rinsing air connection that the holes
in the antenna and in the process fitting correspond. This ensures a
sufficient air flow (the air is led through the holes to the feed system. A
rinsing of the parabolic antenna in total is not intended).
