For bin sizes 15'-36' the center gate is controlled independent of the intermediate gates. For bin sizes
42' diameter and larger the intermediate gate closest to the center gate is operated with the center gate
control. When the center gate is 50% open, the next intermediate gate is opened together with the center
gate such. Similarly, the center and next intermediate gate are closed together.

ALWAYS UNLOAD FROM THE CENTER GATE FIRST. Unloading from the
intermediate gates when the bin is still mostly full, causes excessive stress
on the grain bin and can cause the grain bin to be damaged or collapse.
