Use and Maintain the AeroSpreader Feed Spinner
Adjust the Feed Spread
Change the angle of the nozzle to change the size of the feed spread.
Loosen the bolt (A) on the T-bolt clamp.
Turn the nozzle (B) to set the size of the feed spread.
Turn the nozzle opening down for a smaller spread circle.
Turn the nozzle opening up for a larger spread circle.
Push the nozzle until the edge of the nozzle touches the edge of the upper elbow (C). There must be no gap.
Tighten the bolt (A) on the T-bolt clamp. Do not overtighten the bolt.
Check the Bolt Protectors
Check the bolt protectors regularly. Each bolt protector must cover a bolt. If a bolt is not covered, the end of the bolt can damage fish scales.
Look at the bolt protector at the counterweight. Make sure that the bolt protector covers the counterweight bolt.
If the pole has 2 pieces, look at the bolt protector at the pole connector. Make sure that the bolt protector covers the bolt on the pole connector.
If a bolt protector has moved, slide the bolt protector back over the bolt.

Lift the bearing and the upper elbow off the lower elbow.
Clean with Water and Soap

Rinse the bearing well with clean water.
Clean with Compressed Air
Blow compressed air into the bearing.
Rotate the bearing in both directions while you blow air into the bearing. This removes dirt from inside the bearing.
Attach the Bearing Again
