OPERATIONAL ADJUSTMENTS
1. OUTBOARD AUGER TILT
The standard DESIGN III Stir-Ator has an
adjustable outboard auger tilt. When adjusting
the auger toward the bin wall or if
your Stir-Ator is equipped with an offset
trolley, the inside wall ladder can interface
with the operation of the Stir-Ator and may
have to be removed or reinstalled closer to
the bin wall.

upper bearings. See Photos 1A and 1B.
Loosen the 3/8" nuts on the adjustment bolt
under the trolley. Adjusting this bolt will
move the auger closer or farther from the
wall. See Photo 1C.
