FOLLOW SAFETY INSTRUCTIONS
Carefully read all safety messages in this manual
and on your machine safety signs. Keep signs in
good condition. Replace missing or damaged
safety signs. Be sure new equipment compo-
nents and repair parts include the current safety
signs. Replacement safety signs are available
from the manufacturer.
Learn how to operate the machine and how to
use controls properly. Do not let anyone operate
without instruction.
Keep your machinery in proper working condi-
tion. Unauthorized modifications to the machine
may impair the function and/or safety and affect
machine life.
If you do not understand any part of this manual
and need assistance, contact your dealer.
STAY CLEAR OF ROTATING PARTS
Entanglement in rotating augers will cause serious
injury or death. Make sure everyone is clear of Stir-
Ator before starting or operating the unit.
Keep all shields and covers in place at all times.
Wear close fitting clothing. Stop and lock out power
source before making adjustments, cleaning, or
maintaining equipment.
OPERATE MOTOR PROPERLY
Do not operate the Red Giant Stir-Ator unless the shut-off chain has been
properly installed.
Do not operate electric motor equipped units until motors are properly
grounded. All electrical connections should be in accordance to Local and
National Electrical Codes.
Disconnect power on electrical driven units before resetting motor overloads.
Do not repetitively stop and start the drive in order to free a plugged condition.
Jogging the drive in this type of condition can damage the equipment.

6PNEG-1358 Red Giant Stir-Ator
PRACTICE SAFE MAINTENANCE
Always disconnect and lockout all power
sources before servicing equipment.
Understand service procedures before doing
work. Keep area clean and dry.
Never lubricate, service, or adjust machine while
it is in operation. Keep hands, feet, and clothing
from rotating parts.
Keep all parts in good condition and properly
installed. Fix damage immediately. Replace
worn or broken parts. Remove any build up of
grease, oil, or debris.
Use
Ladders
Safely.
AVOID FALLS
When working using ladders be sure to have rubber pads or
some other method of keeping the ladder from slipping on
the bin or silo floor.
Because the Stir-Ator is suspended from chains in the
center, be cautious of positioning ladder against the Stir-Ator.
The Stir-Ator can move or swing from the weight of a person
climbing on the ladder.
Also, when setting a ladder against the Stir-Ator, a vise grip
or some other type of tie down should be used in the front
and back of the track drive unit. This keeps the Stir-Ator from
rolling or sliding around the bin while service work is being
performed.
During heavy service work, such as removing auger drive,
electric motors, or replacing electrical swivel, tying the ladder
to the main frame or some other solid component is advised.
Using a ladder in a partially filled bin is not recommended.
The ladder can sink into the grain allowing it to become
unstable and fall.
Climbing out on the main frame from either a ladder or roof
manhole should not be attempted. The Stirator can swing,
causing a fall.
Do not climb Stirator down augers to make adjustments or
re-pairs. Slipping could cause falling, bodily injury, or both.

Keep a first aid kit and fire extinguisher handy.
Keep emergency numbers for doctors, ambu-
lance service, hospital, and fire department near
your telephone.
WEAR PROTECTIVE CLOTHING
Wear close fitting clothing and safety equipment
appropriate to the job.
Safety glasses should be worn at all times to
protect eyes from debris.
Wear gloves to protect your hands from sharp
edges on plastic or steel parts.
A respirator may be needed to help prevent
breathing potentially toxic fumes and dust.
Wear hard hat and steel toe boots to help
protect your head and toes from falling debris.

FINAL INSPECTION CHECK LIST
1. HAVE YOU READ THE OWNER’S MANUAL COMPLETELY - YOURSELF? STUDY IT.
2. Is there at least 7" clearance between the top of the track and the lowest part of the roof or roof
braces?
3. Are the track splices correctly installed? Consult the Drawings in the OWNER’S MANUAL?
4. Is the suspension tee properly hung, LEVEL, with the end loops down, with lead-in wire and
shut-off chain properly installed?
5. IstheframeoftheStiratorabout1"higheratthecenter of the bin for NEW BIN INSTALLATION,
and LEVEL WITH EXISTING BINS?
6. Are augers 3" off the drying floor at the bin wall?
7. Were the augers notched with a file (NOT A TORCH) where the clamp bolts serve as a driving
key?
8. Did you note the instructions NOT to weld flighting at the top end of the auger?
9. Are you keeping a record of the serial number of each owner?
10. IfyourRedGiantStir-atorisequippedwiththreephasepower,BESUREYOURELECTRICIAN
HAS INSTALLED ADEQUATE MOTOR PROTECTION, (either magnetic or manual starters
can be used) or you will void the warranty on your three-phase motors.
11. Didyoumakesurethattheownerreceivedhisowner’smanual,andwasinstructedthatreading
and understanding the manual will help immensely?
12. If electric motors other than the ones provided by David Manufacturing Company are used,
modification of the motor belt shield may become necessary. Cut to fit. Do not operate without
the shields being in place.
13. Did you put safety decals on bin; inside walk-in door; under side of man-hole cover?
14. NOTE: Operating the Stir-Ator during bin unloading can be beneficial, and can prevent auger
damage. When the grain no longer flows into the center sump, the Stir-Ator should be shut off
to prevent auger damage.

STEP 1
All Red Giant Grain Stir-Ators come
shipped as follows:
(1) Trolley Base Assembly - 4 Auger
and 6 Auger Units
(1) Trolley Extension Bundle -
6 Auger Only
(1) Frame Rail Bundle
(1) Track Bundle
(1) Electrical Parts Box 26" x 26" x 18"
(2) Parts Boxes 16" x 16" x 54"
STEP 2
Before starting to assemble the bin, the
complete Red Giant Stir-Ator, less augers,
should be laid in the center of the concrete
pad. The top ring and roof assembly of the
bin is assembled in the usual way. The
Stir-Ator wall track is then installed, as
shown in (Drawing A on page 33.) The
5/16" hole for the track bolts should be
drilled, or punched, in the bin metal
progressively; that is, starting with a
double-hole end of a track section, the first
hole is drilled or punched, and the three-
hole connector, track bracket, and bolt
installed. Then, using the holes in the track
as a guide, the rest of the bolts and
brackets can be installed around the bin.
Be sure to have track splices smooth and
aligned. See parts Drawing "O" on page
28.
ALL RED GIANT STIR-ATORS
REQUIRE 12-5/8" SPACING TRACK.

MANUFACTURER FOR ANY
SPECIAL UNIT HANGING OR
SUPPORT LOCATIONS.
NOTE

14 PNEG-1358 Red Giant Stir-Ator
STEP 3
NOTE THE SEVEN-INCH DISTANCE
FROM THE EAVE OF THE BIN TO THE
CENTER LINE OF THE HOLES IN THE
TRACK. Bins with steeply-pitched roofs
may allow the 7" distance to be reduced.
Roofs with the low or “flat” profiles may
require more clearance. Reinforcements
for the roof or inner ladders which might
interferewiththemovementofthe Stir-Ator
should be trimmed off as indicated in
Drawing A on page 33. If this cannot be
done, the 7" distance from the eave to the
bolt holes must be incresed
proportionately.
STEP 4
There should be slightly more track
materialthan isrequired.Uponmaking the
complete circuit of the bin, the end of the
last section should be cut off so as to fit
snugly against the forward end of the first
length and a 7/16" hole drilled, 5/8" from
the cut-off end. ALL TRACK JOINTS
SHOULD BE ALIGNED AS SMOOTHLY
AS POSSIBLE. Mis-alignment should be
correctedbyfilingor bending,ifnecessary.
STEP 5
Because the Stir-Ator augers run very
close to the bin wall, INSIDE WALL
LADDERS MUST BE MOUNTED VERY
CLOSETOTHE BIN WALL. If this cannot
be accomplished, the ladder must be
removed.Aportableladder isadvised,and
this can be obtained form your dealer. If
thewalk in door protrudes over 2-1/2" into
the bin itself, SKID PLATES SHOULD BE
PUT ON THE DOOR so that the augers
will not get caught during Stir-Ator
operation.
NOTE THE CLEARANCE REQUIREMENTS IN
DRAWING A AND B.
STEP 6
At this time, hook the three suspension chain hooks over the
top edge of the fill hole. Space them equally around the fill
hole. See Drawing B on page 36 or Photo 1.
STEP 7
Install the switch box above the inspection hole. Be sure the
Red Giant will not hit it,and do not forget the brace. See Photo
1 or Drawing A on page 33.
Lead-in cord and shut-off chain need to be positioned so that
the Stir-Ator will not catch them as it rotates around the bin.
