Threaded connection on the sprinkler is 2½" female thread.
For sealing the thread, hemp and a jointing compound has to be used e.g. Fermit special

Do not turn the sprinkler by using the jet pipe.
Screw on the connection socket up to the detent, so
that the sprinkler cannot unscrew itself during
operation.
The impact lever has to deflect approx. 60 degrees. The angle of
deflection can be regulated at the stop screw, after the hexagon nut
has been loosened. The marking is on the inside of the screw (bolt).
If the sprinkler is equipped with nozzles that have a smaller
diameter, or if the operating pressure is somewhat lower, then the
impact lever will have a smaller angle of deflection.
Larger deflection = turn the screw in the direction +.
If bigger nozzles are used, or if the pressure is high, the angle of
deflection will be larger.
Less deflection = turn the screw in the direction -.

The braking effect can be set, after the both lock
nuts has been loosened.
More braking effect, tighten the grub screw.
Less braking effect, loosen the grub screw.
The braking effect should be such, that the
sprinkler does not turn backwards, during
rotation of the impact lever.
Loosen or tighten both grub screws in the same
way.
