PNEG-1156ETL Design III Series Grain Stir-Ator CSA 41
6. The unit should be hung slightly higher at the center than at the bin wall. Stand at a right angle to the
frame rails and sight along them and across to the wall track. When the center height is properly
positioned, the frame should be 1" higher at the center on an 18' diameter bin; 1-1/2" higher on
a 27' diameter bin; and 2" higher on a 36' diameter bin. Be sure the suspension tube is always
positioned level so it will not be hit by any part of the Stir-Ator as it rotates around the bin.

1. Check to be sure the shut off hook end of the suspension tube is located 90° to the switch box. If not,
reposition the suspension chain hooks around the center fill hole.
2. Attach the link end of the shut off chain to the “S” hook on the switch box handle. Re-hook the
excess chain with an “S” hook attached to the shut off chain so that it will not get caught on the unit.
