Red Giant Grain Stir-Ator - David Manufacturing Co.

The augers are manufactured to allow
them to be shortened by cutting off from
the bottom end instead of the top. All
augers have flighting to within 8" of the top,
and hard surfaced augers will have all but
the top pitch of flighting hard surfaced. Lay
the auger down and mark where the auger
will be cut off. Weld the flighting to the shaft
in three places within the first pitch just
above this mark before cutting off the
bottom part of the auger. See Photo 36
and Auger Cut-off Drawing. File a notch
on each side of the shaft, 3/4" down from
the top end of the auger. Install the augers
to the gear box output shafts with the 2
piece auger couplers. Tighten the clamping
bolts uniformly on each side of the clamp
to insure that the auger is aligned to the
output shaft. See Drawing N on page 57.

Weld last pitch in three
places with 3/4" long welds.
DO NOT WELD THE FLIGHTING TO
THE SHAFT AT THE TOP OF THE AU-
GER. TO DO SO VOIDS THE WAR-
RANTY. THE FLIGHTING AND SHAFT
MUST REMAIN UNWELDED TO MINI-
MIZE DISTORTION AND WEAKENING
OF THE SHAFT.
STEP 34
A professional electrician should be
employed to bring power line to the Red
Giant Stir-Ator. IF EQUIPPED WITH
THREE PHASE, THE CUSTOMER MUST
PROVIDE MOTOR PROTECTION,
EITHER MANUAL OR MAGNETIC. THE
BIN MUST BE GROUNDED.
STEP 35
To test Stir-Ator operation in an empty bin,
be sure no one is inside the bin, then turn
“on” and “off” immediately. DO NOT
OPERATE THE RED GIANT STIR-ATOR
IN AN EMPTY BIN.
Install the “Danger” decals on the bin. One
on the inside of the walk-in door and one
on the inside of the manhole door. Place
the “DMC - Red Giant” decal on the outside
of the walk-in door.
