Siemens interranger DPS300 Instructional Manual page 34

Extending the Arms
Swing the extension arms (and transducer assembly) out 90 degrees into the
clarifier and bolt the extension arm hinges to the chassis using the supplied
washers and nuts.
Before Leaving
If a Siemens Skimmer Guard is used, insure that is has been properly oriented in
line with the skimmer's travel. Refer to the Skimmer Guard instructions.
Insure that the conduit clamping u-bolts are sufficiently tight to hold the conduit
fixed.
Start the skimmer and let it pass by the Skimmer Guard (if used) to ensure that
everything is well-positioned. See Orienting the Skimmer Guard on page 31 for
more details. Make any necessary adjustments and tighten the 1" u-bolts securely.
Finally, bolt the extension arms to the base plate.
