3. Introduction
Product Introduction
Congratulations! Your selection of the GSI Series II Sweep is a wise investment. It will give you years of
dependable service. The main function of the Series II Sweep is to clean out the remaining grain, from
the bin, after all gravity unloading has finished. The GSI Series II Sweep is a single pass sweep only.
The unit will only operate in a round grain bin equipped with a center sump in the bin floor.
NOTE: The bin manufacturer should be contacted for their recommendations on your bin’s structural
integrity. The following are sweep criteria recommendations.
Issues Recommendations
A track is required under each of the sweep tires and jack wheels where they travel
over the aeration (steel) floor. This is the case for all steel flooring including full floor
and flush floor aeration. The track should be a minimum of 10 Ga. thick and made
from steel. The steel can be galvanized for the jack wheel paths but needs to have
a non-slip coating for the drive tire paths. The drive tire track coating must not be
Flooring
course enough to damage the drive tires. A Chart on Page 18 is included that shows
radius dimensions locating the points of contact between the sweep and the bin floor.
The dimensions may be used to figure the material quantities of track to support the
sweep across the aeration flooring. The track material is not supplied with the sweep
and must be supplied by the installer or purchased from GSI. The dimensions
are approximate and the assembled sweep should be checked for exact points
of contact.
When installing a 12" standard sweep, the minimum recommended opening is
36" x 36". With a 16" standard sweep, it is 42" x 42". If installing a sump with collector
ring, the opening will be 42" x 42" for both sweep sizes.
Center Sump Size
Number of Intermediate Sumps
Routing the Power Supply to
the Sweep
Floor Level Tolerance
The sump hopper supplied by GSI was designed with sufficient clearance around the
collector ring housing to allow grain to gravity flow through the hopper and be carried
away by the material handling equipment below. 42-3/4" is the maximum opening
size to allow rolling clearance for the casters assembled to the head end jack. If
made smaller, grain flow may be decreased to an unacceptable level.
**Flow of grain is limited to 15,000 BPH when using this sump and collector ring
housing assembly. The collector ring housing extends 22-1/2" down from the floor
surface and is approximately 14-1/4" x 14-1/4" in size.
Intermediate sump pumps must be installed on a maximum of 10' centers where the
sweep will be parked during storage. The first intermediate sump should be placed at
a maximum of 10' from the center sumps and the end sump should be no more than
4' from the bin wall.
The extra sumps will help clean out the grain in front of the sweep, reducing the
start-up load. Doing this will save labor dollars and hours of work to dig out the
sweep and will help the sweep during start-up. The sweep is not designed to start-up
when submerged in material. The sweep should be parked behind the intermediate
sumps with sumps on the auger side of the sweep.
There are three (3) options for routing the power. The most common option is to run
the cords out the door in the sidewall. Another option is to use the hopper sump with
collector ring. This allows the power to be transferred through a mechanical device in
the center sump and does not twist any cords. The third option is to use the pivot kit,
which routes the power cord through the center sump. Using this kit requires the
sweep to be backed up to the start point after sweeping. The pivot kit is not the
preferred choice due to the repeated cord twisting.
The top edge of the sump hopper and the top edge of the “X” brace support must be
level with the floor. The floor must be level within 3/4" plus (or) minus, preferably less.
Any high or low points must be gradually sloped. The change in elevation should be
no more than 3/4" over 60".
PNEG-720-G2 12" and 16" Series II Sweep 15
3. Introduction
Issues Recommendations
Bin Roundness Tolerance
Bin Opening Size
Required for Installation
Voltage Specification
Diameter tolerances are limited by foundation limits and sweep operation as well as
structural issues. For 72' diameter and larger, the overall tolerance would be plus or
minus 1-1/4" on the radius, plus or minus 1" on 42'-66' diameter bins and plus or
minus 3/4" on 30'-39' bins.
The tail section is the largest piece of a standard Series II Sweep. The dimensions
for a 16" tail section are 23-1/2" x 55-1/4". If the bin wall is not too thick, this unit
should fit through a 23-1/2" x 47" opening. The dimensions for a 12" tail section are
21-1/4" x 51-1/2". Again, if the bin wall is not too thick, the section should fit through
an opening 21-1/2 x 45".
GSI offers a special Knock Down Sweep, uniquely designed for storage units with
small doors. This sweep is broken into 10 main pieces that can fit through a door as
small as 30-1/2" in diameter for 16", 27-1/2" in diameter for 12" or a 20" x 24"
rectangular door. The components are then assembled inside the storage unit.
The Series II Sweep is designed to operate using 460 Volt 3 Phase 60 Cycle
Power. The voltage must be within plus or minus 4% for proper operation.
Voltages outside of this range may cause excessive power draw or other operating
problems. Please contact the factory for applications outside of these parameters.
Electrical controls and wiring should be installed by a qualified electrician. The motor
disconnect switches and conductor cables should comply with the National Electric
Code and any local codes which may apply.
Electrical Requirements
A main power disconnect switch capable of being locked only in the OFF position
should be used. This has been integrated into the control panel after June of 2010.
Disconnect and lock out the power before servicing the equipment, entering the bin
or resetting the motor overloads.
The control panel MUST be mounted OUTSIDE the bin near the door. It must be
located so the operator has a full view of the equipment and can see that all
personnel are clear. It must NEVER be installed inside the bin. The foot switch has to
be plugged into the control panel and depressed before the sweep is operational.
It has a 10' cord so the sweep can only be monitored from OUTSIDE the bin. The
thermal protection cord must also be wired into or plugged into the control panel
before the sweep will operate.

4. General Product Information
There should ALWAYS be two (2) people in the work area.
A main power disconnect switch capable of being locked only in the OFF position
should be used. It should be locked in the OFF position whenever work is being
done on the Series II Sweep.
NOTE: The horsepower recommendations are for augering reasonably dry grain. High moisture grain
(greater than 15%) will require greater power for maximum capacity.
NOTE: Sweep drive and carrier wheels require plates or track over aeration flooring for travel and
supports not supplied with the sweep unit. Contact your installer or flooring provider for possible
sources and details.
B. A magnetic starter should be used to protect the motor when starting and stopping. It should stop
the motor in case of power interruption, conductor fault, low voltage, circuit interruption or motor
overload. The motor must be restarted manually. Some motors have built-in thermal overload
protection. If this is the type of motor being used, use only those with a manual reset.
C. The motor starting controls must be located outside the bin. They must NEVER be installed on the
Series II auger inside the bin.
D. Disconnect and lock out the power before resetting motor overloads.
E. Disconnect and lock out the power before entering the bin.
F. Disconnect and lock out the power before servicing the equipment.
G. Position the reset and motor starting controls so that the operators have full view of the equipment.
WARNING
H. Make sure electric motors are grounded.

4. General Product Information
Grade 5 Bolts
Grade 5 bolts are designated by three (3) slash marks on the head.
Grade 8 Bolts
Grade 8 bolts are designated by six (6) slash marks evenly spaced on the head of the bolt.
Under no condition shall any other fasteners be substituted for those supplied
by the manufacturer.
Torque values to be used when tightening the bolts on the Series II Sweep
It takes more force to tighten a 3/4"-10 bolt than to tighten a 1/2"-13 bolt because of its larger diameter. It
also takes more force to tighten a Grade 8 bolt than it does to tighten a Grade 5 bolt because of the greater
material strength. A bolt that is waxed or otherwise lubricated requires much less force to tighten. If the
same amount of force is used with a lubricated bolt as with a non-lubricated bolt, the lubricated bolt often
will break.
A Suggested Initial Tightening Torque is listed in the Chart below.

4. General Product Information
Wedging forces in the bushing saw slot, such as that exerted by a narrow edged
regular screw driver, may damage or break the bushing. This damage would not
be covered under the GSI warranty.
Do not lubricate the bushing taper, bushing bore, hub taper or the shaft. Doing so
could result in breakage of the product.
Do not use worn hex key wrenches. Doing so may result in a loose assembly or
may damage the screws.

2. Insert bushing in hub. Match the hole pattern, not threaded holes (each complete hole will be
threaded on one side only).
3. Lightly oil set screws and thread into the half-threaded holes indicated as in Figure 4A.
4. Position the assembly onto the shaft allowing for the small axial movement which will occur during
the tightening procedure.
5. Alternately torque set screws to recommended torque setting listed in the Chart below.
6. To increase the gripping force, hammer the face of the bushing using a drift or sleeve. (Do not hit the
bushing directly with the hammer.)
7. Re-torque the screws after hammering.
8. Recheck the screw torques after the initial run-in and periodically thereafter. Repeat Steps 5, 6
and 7 if loose.

4. General Product Information
Do not lubricate the bushing taper, bushing bore, hub taper or the shaft. Doing so
could result in breakage of the product.
Excessive screw torque may cause damage to either the bushing and/or the
sheave. Uneven pressure on the jackscrews may also damage the bushing flange
making removal difficult without damage to the bushing and/or sheave.
Do not use worn hex keys and/or wrenches. Doing so may result in a loose
assembly or may damage the screws.
To Remove
1. Remove all cap screws.
2. Insert the cap screws into the threaded jack hole or holes.
3. Tighten all the jackscrews alternately and evenly beginning with the screw farthest from the bushing
saw slot. Tighten until the bushing grip is released. Slide the unit off the shaft.
