Chapter 1: Safety Precautions
Maintain Equipment and Work Area
• Understand service procedures before doing work. Keep
area clean and dry.
• Never service equipment while it is operating. Keep hands,
feet, and clothing away from moving parts.
• Keep your equipment in proper working condition. Replace
worn or broken parts immediately.
ST-0003–1
Operate Motor Properly
• All electrical connections must be made in accordance with
applicable local codes (National Electrical Code for the US,
Canadian Electric Code, or EN60204 along with applicable
European Directives for Europe). Make sure equipment and
bins are properly grounded.
• Lock-out power before resetting motor overloads.
• Do not repetitively stop and start the drive in order to free a
plugged condition. Jogging the drive in this manner can
damage the equipment and drive components.
ST-0009–3
Rotating Auger Hazard
• Keep clear of rotating augers and
moving parts.
• Do not remove or modify guards or
covers.
• Lock-out power source before making
adjustments, cleaning, or maintaining
equipment.
• Failure to follow these precautions will
result in serious injury or death.
ST-0037–1
Stay Clear of Hoisted Equipment
• Always use proper lifting or hoisting equipment when assem-
bling or disassembling equipment
• Do not walk or stand under hoisted equipment.
• Always use sturdy and stable supports when needed for
installation. Not following these safety precautions creates
the risk of falling equipment, which can crush personnel and
cause serious injury or death.
ST-0047–1

Chapter 1: Safety Precautions
Stay Clear of Rotating Parts
• Do not enter the bin while the equipment
is in operation.
• Entanglement in rotating augers will
cause serious injury or death.
• Keep all guards and covers in place at
all times.
• Lock-out power source before making
adjustments, cleaning, or maintaining
equipment.
ST-0008–2
Use Unload Equipment Properly
• Do not operate this equipment alone. Make sure someone
nearby is aware of the proper shut down sequence in the
event of an emergency.
• Do not allow any person intoxicated or under the influence of
drugs to operate this equipment. All operators must be
adequately rested and prepared to perform all functions of
operating the equipment.
• Do not start equipment until all persons are clear of the work
area and safety guards are in place.
• Do not allow anyone inside a bin, truck, or wagon which is
being unloaded by an auger. Flowing grain can trap and suf-
focate in seconds.
• Use ample overhead lighting after sunset to light the work
area.
• Always use caution to not hit the auger when positioning the
load.
• Do not leave equipment operating while unattended.
• Be aware of pinch points, which can trap or catch objects
and cause injury.
• Be sure all equipment is locked in position before operating.
• Always lock out all power sources to the equipment when
unloading is finished.

Chapter 2: General Information
Bolt Torque Specifications
What You Should Know
It takes more force to tighten a 3/4'' bolt than to tighten a 1/2'' 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.
CAUTION
Under no condition shall any other fasteners be substituted for those supplied by
the manufacturer.

Chapter 2: General Information
Auxiliary Intermediate Well
What You Should Know
In all the power sweeps, the well which is immediately next to the center well is the auxiliary intermediate
well. There will be a need to use the auxiliary intermediate well if the center well is plugged or if there is
any difficulties in opening the center well during the gravity unloading process.
1. The auxiliary intermediate well (61) is the intermediate well closest to the center well (53) and will be
operated by the smaller diameter control rod.
2. The auxiliary well control rod (81) is assembled as rod-in-rod with the larger diameter intermediate
well control rod (75) and can be connected to the rack and pinion assembly (77) tube by placing a
5/16" x 1-1/2" HHCS bolt (17) through the rack and pinion assembly (77) tube to the auxiliary well
control rod (81).
NOTE: During gravity unloading, if the center well (53) is plugged, the auxiliary intermediate well
gate (116) must be opened independently from the rest of the intermediate well gates (70).
Make sure to remove the 5/16" x 1-3/8" safety pin (80) to open the auxiliary well gate (116)
alone.

Chapter 3: Installation
Power Sweeps in Bins with Concrete Floors
NOTE: GSI does not recommend installing the Direct Gear Drive Power Sweep in concrete. When
flush-floor installations are necessary, a pre-formed trench is needed. A steel trench cover
adequate for the grain height and trench size must be installed. Consult the factory for further
information.

Chapter 3: Installation
Installing the Center Well
1. Locate the center of the bin and place the center well (53) into position with the vertical shaft in the
gearbox at the center of the bin.
2. Attach the center well (53) to the unload tube (54) using four half bands (55), eight 5/16" x 1-1/4"
HHCS bolts (16) and eight 5/16" flange nuts (39).

53 Center well 62 Center well gate
3. Level the center well (53) to the concrete floor by adjusting the length of the leveling leg (56) using
both 3/4" hex nuts (44) (above and below the center well flange) located at the bottom corners of the
center well (53).

Chapter 3: Installation
Installing the Bin Flange for Unload Tube
1. Attach the upper bin flange (57) and lower bin flange (58) loosely to the unload tube (54) using
5/16" x 1-1/2" HHCS bolts (17) and 5/16" flange nuts (39).

54 Unload tube
2. Make sure that the bin wall opening is large enough for the well control rods to pass through the bin
wall before connecting the flange to the bin wall.
3. Slide the bin flanges flush up to the bin wall and tighten the bolts connecting the two flanges.
4. Drill the holes in the bin wall through the four holes located in the upper bin flange (57) and two
holes located in lower bin flange (58) and secure the bin flanges to the bin wall using six standard
bin bolts (A) and flange nuts (B).
