DO NOT STORE SWEEPS IN THE BIN!
Sweeps are NOT designed to remain in a bin during
filling, storage, or bottom (gravity) unloading. A sweep
left in a bin during these operations may be serverly
damaged. The GSI Group, Inc. will not be responsible for
such damages.
The following action may reduce damages to a sweep
remaining in a bin: Lifting the sweep off the center pivot,
positioning it parallel to the intermediate wells (along
side of - not on top of) and fully supporting the sweep to
the bin floor. However, even with this procedure, The
GSI group, Inc. will not be responsible for any damges to
the sweep.

the drive belts are installed.
Oil must be added before assembly. The chain
reducer is shipped without oil.
Do NOT add more oil than recommended. Additional oil may damage the seals or be forced out
through the vented fill plug.
For lubrication in normal operating temperature
between 40° F to 120° F, we recommend the use
of non foaming, multi purpose gear oil, SAE 90
weight. For temperatures below 40° F, use a SAE
80 weight oil. Use grade commercially available
for automotive differentials. Extra pressure
additives may be of value in severe applications.

3. FLIGHT & SHIELD ASSEMBLY
Assembly
A Commercial Bin Sweep can be made up of several
sections of flighting and back shields. The quantity and
lengths of the sweep flight and back shield sections will
vary depending on the bin size. Use the chart below for the
number and length of sections for your size of bin.
The sweep flight with a cut back must connect to the drive
assembly . The remaining sections should be assembled in
the order shown in the chart below. The section furthest
from the drive has mounting holes for the sweep tractor .
The assembly instructions in this section cover assembling the complete Commercial Sweep. Refer to pages 3033 and read where use of only a part of the sweep auger
may be recommended when starting to sweep unload a
bin, particularly a large bin. You may choose to only
assemble one or two sections of sweep flight, back
shields, and bearing stands for initial sweep unloading.
Remember, any number of sweep sections can be used
together up to a maximum of six. If a sweep auger with
four or more sections was selected, a truss assembly is
included. The truss should be used when four or more
sections are assembled together. Refer to p age 24 for
truss assembly instructions. If the truss assembly you
have is for a greater number of sweep auger sections
than you are assembling, be sure to tie off the extra
cable length so it does not become entangled in the
sweep auger.

9. INSTALLATION & UNLOAD PROCEDURES
A. Shut down and lock out the unloading unit before
entering the bin.
If the bin is not equipped with intermediate wells, the
Commercial Sweep Auger may be placed in the bin
after all the grain has been removed that will gravity
flow through the center well.
The grain remaining should appear as in Figure
21. DO NOT enter a bin if the grain has bridged or
flowed abnormally out of the bin as shown in
Figure 19 or Figure 20. Suffocation can occur if
grain suddenly breaks loose, burying persons
who are inside the bin.
Abnormal grain flow can easily fall and bury
a person, suffocating them. DO NOT enter a
Figure 19
bin with abnormal grain flow.
Keep clear of all augers.
DO NOT ENTER this bin!
If you must enter this bin:
1. Shut off and lock out all power.
2. Use safety harness and safety line.
3. Station another person outside the bin.
4. A void the center of the bin.
5. Wear proper breathing equipment
or respirator .
Failure to heed these warnings will
result in serious injury or death.
Figure 20
Bridged grain can easily break loose and
bury a person, suffocating them. DO NOT
enter a bin with bridged grain.
Figure 21
Grain should look similar to this. Always
shut down and lock out the power to all
devices before entering a bin.

9. INSTALLATION & UNLOAD PROCEDURES (cont.)
B. If the bin is equipped with intermediate bin wells, open
them after grain has stopped flowing into the center
well and before the sweep auger is placed in the bin.
Open the intermediate wells near the bin center first.
Then when grain flow stops, open the wells near the
bin wall. (See Fig. 22 and Fig. 23) The Commercial
Bin Sweep Auger can then be installed. Always shut
down the unloading equipment and lock out power
before entering the bin.
C. Place the sweep motor mount pivot pin into the pivot
tube of the center well. Lay the sweep auger assembly on the pile of sloping grain or in the area of the
intermediate wells where additional grain has been
removed.
Figure 22
Installation
KEEP OUT OF BIN WHILE SWEEP IS IN OPERA TION.
D. The Commercial Bin Sweep Augers are made with the
sweep auger and back shield in two or more sections.
One of the sections can be used first alone by attaching the section to the drive unit and mounting the
reduction wheel on that section. Then, after the center
portion of the bin has been emptied, another section of
sweep auger and back shield may be added and the
unloading process continued. (See Fig. 24, 25, and
26) If the sweep is equipped with a truss, be sure to

tie-off extra cable length so it does not become
entangled in the sweep auger . Always shut down the
unloading equipment and lock out power before
entering the bin.
Using the gradual method of unloading described
above helps to avoid situations where cascading grain
can bury the sweep causing high torque loads and
possible damage to the sweep assembly . This kind of
12" & 14" Commercial Bin Sweep Augers PNEG-1050
damage is not covered by the warranty .
This type of operation may also be used to prevent the
unloading of one side of the bin totally before any grain is
removed from the other side. T otal unloading of one side of
large diameter bins without some unloading from the other
side can cause structural damage to the bin. Check with
your grain bin dealer or the bin manufacturer for bin
unloading recommendations.

Installation
10. INSTALLATION & UNLOAD PROCEDURES (cont.)
E. Attach suitable electric wiring to the motor in a
manner that will permit the sweep to rotate several
times about the bin. The motor starting controls must
be located outside of the bin. They must never be
installed on the sweep auger inside the bin. Locate
the motor starting controls outside the bin, but near
the door so the operator has full view of the operation
inside the bin. (See Fig 27.)
F. S tart the under floor bin unloading equipment before
starting the Commercial Bin Sweep Auger. The sweep
auger will work towards the floor at approximately a

45° angle and then empty the bin or center area of the
bin in one revolution after reaching the floor . As soon
as the bin or center area of the bin empties, the
sweep auger will rotate rapidly around the bin. Shut
down the sweep auger as soon as the bin or center
area of the bin is empty .
The height of the Commercial Bin Sweep back shield
above the bin floor can be adjusted at the motor mount
and at the bolted connection between back shields.
Be sure back shields will clear splices in metal
flooring or cracks in concrete floors.

11. FINAL CLEAN-OUT
The following procedure is recommended for cleaning the
floor of the bin after the sweep auger has removed as
much grain as possible.
1. Lockout all power.
2. Clean (scoop and sweep by hand) the outer area of
the floor into a circular pile towards the center of the
bin. (See Fig. 28)
3. Get out of the bin.
4. After making sure everyone is outside the bin and
clear of the equipment, start the under floor unloader
and the sweep auger. In a short time, the circular pile
towards the center of the bin will have been removed.

Power Source
12. POWER SOURCE
A. The horsepower recommendations are for augering reasonably dry grain. High moisture grain (above 15%) will
require greater power if maximum capacity is to be maintained. The maximum possible capacity will be less
with high moisture grain than with dry grain.
A main power disconnect switch capable of being locked only in the off position should be
used. The switch should be locked out whenever sweep is not in operation.
1. Electric motors and controls should be installed by a qualified electrician and must
meet the standards set by the National Electrical Code and all local and state codes.
2. A magnetic starter should be used to protect your motor when starting and stopping. It
should stop the motor in case of power interruption, conductor fault, low voltage,
circuit interruption or motor overload. Then the motor must be restarted manually.
Some motors have built-in thermal overload protection. If this type motor is used, use
only those with a manual reset.
3. The motor starting controls must be located outside the bin. They must never be
installed on the sweep auger inside the bin. Locate the motor starting controls outside
the bin, but near the bin door so the operator has full view of the operation inside
the bin.
4. Disconnect power before resetting motor overloads.
5. Reset and motor starting controls must be located so that the operator has full view of
the entire operation.
6. Make certain all electric motors are grounded.
7. Shut off power to adjust, service or clean.
Use the table below to determine the horsepower and electric motor pulley size your specific
sweep requires. Use an electric motor that operates at 1750 RPM (motor pulley not furnished).

(non-foaming) oil until the oil level reaches the
check point.
B. For lubrication in normal operating temperature
between 40º F to 120º F , we recommend the
use of non-foaming, multi purpose gear oil. Use
SAE 90 weight for normal operating temperatures. For temperatures below 40º F , use SAE
80 weight oil. Use a grade of oil commercially
available for automotive differentials. Extra
pressure additives may be of value in severe
applications.
Enclosed Drive
Fill Plug
15. REDUCTION SWEEP WHEEL
A. Add two ounces of multi purpose gun grease to the
sweep wheel drive enclosure during assembly and
each time the bin has been emptied. Use the grease
zerk on the drive housing.
16. TROUBLE SHOOTING
A. LOW CAPACITY
Sweep capacity may vary as the angle of sloping grain
varies. Check the horsepower requirements on pages 34,
to determine correct operating speed and the motor pulley
size recommended for that speed. If a greater or lower
capacity is desired it may be possible to change the
motor pulley which will change the sweep flight speed. Do
not attempt operation at speeds greater than 50 to 100
RPM above standard recommended speed. Do not operate
a sweep that is overfeeding the unloading auger unit. The
slide gate in the center well should be left full open during
sweep operation.
B. SWEEP FLIGHT & BACK SHIELD NOT MOVING
DO NOT STORE SWEEPS IN THE BIN!
Sweeps are NOT designed to remain in a bin during filling,
storage, or bottom (gravity) unloading. A sweep left in a bin
during these operations may be serverly damaged. The
GSI Group, Inc. will not be responsible for such damages.
Check Plug
FIG. 30
DO NOT add more oil than recommended.
Additional oil may damage the seals or be forced
out through the vented plug.
12" & 14" Commercial Bin Sweep Augers PNEG-1050
The following action may reduce damages to a sweep
remaining in a bin: Lifting the sweep off the center pivot,
positioning it parallel to the intermediate wells (along side
of - not on top of) and fully supporting the sweep to the bin
floor. However , even with this procedure, The GSI group,
Inc. will not be responsible for any damges to the sweep.
Check clearance between back shield and the bin floor for
excessive drag. It may be possible to adjust the back
shield up by working the slotted connections between
back shields at bearing brackets.
The grain may have gone out of condition due to moisture
or insect activity and has become hard or caked. Stop the
sweep auger and lockout power before entering the bin to
correct this or any other difficulty . Make sure the grain
hasn’t flowed abnormally or bridged over. See p age 30 for
illustrations.
