General Safety Statement
Our foremost concern is your safety and the safety of others associated with grain handling equipment.
This manual is to help you understand safe operating procedures and some problems that may be
encountered by the operator and other personnel.
Asownerand/oroperator, youareresponsible toknow whatrequirements,hazards,and precautionsexist
and inform all personnel associated with the equipment or in the area. Safety precautions may be required
from the personnel. Avoid any alterations to the equipment, which may produce a very dangerous
situation, where SERIOUS INJURY or DEATH may occur.
You should consider the location of the bin site relative to power line locations or electrical transmission
equipment. Contact your local power company to review your installation plan or for information
concerning required equipment clearance. Clearance of portable equipment that may be taken to the bin
site should also be reviewed and considered. Any electrical control equipment in contact with the bin
should be properly grounded and installed in accordance with National Electric Code provisions and other
local or national codes.
This product is intended for the use of grain storage only. Any other use is a misuse of the product.
Sidewall bundles or sheets must be stored in a safe manner. The safest method of storing sidewall
bundles is laying horizontally with the arch of the sheet upward, like a dome. Sidewall sheets stored on
edge must be secured so that they cannot fall over and cause injury. Use care when handling and moving
sidewall bundles.
Personnel operating or working around equipment should read this manual. This manual must be
delivered with equipment to its owner. Failure to read this manual and its safety instructions is a
misuse of the equipment.
This product has sharp edges, which may cause serious injury. To avoid injury, handle
sharp edges with caution and always use proper protective clothing and equipment.

Safety Sign-Off Sheet
As a requirement of O.S.H.A., it is necessary for the employer to train the employee in the safe operating
and safety procedures for this equipment. This sign-off sheet is provided for your convenience and
personal record keeping. All unqualified persons are to stay out of the work area at all times. It is strongly
recommended that another qualified person who knows the shut down procedure be in the area in the
event of an emergency.

Proper Storage of Grain Bin/Silo Materials Prior to Construction
Wetstorage stain(rust) willdevelopwhen closelypacked bundlesofgalvanizedmaterial, suchas sidewall
and roof sheets, have moisture present. Inspect roof and sidewall bundles on arrival for any moisture. If
moisture is present, it must not be allowed to remain between the sheets. Separate the sheets or panels
immediately and wipe them down. Spray with a light oil or diesel fuel.
If possible, sidewall bundles, roof sheets and other closely packed galvanized materials should be stored
in a dry, climate controlled building. If outdoor storage is unavoidable, the materials should be stored so
that they are raised above the ground and vegetation. Any stacking and spacing materials should not be
corrosive or wet. Be sure to protect materials from the weather, but permit air movement around the
bundles if possible.
Storing roof bundles and sidewall sheets at a slight incline can also help minimize the presence of
moisture. Storing the bundles with the center of the dome up (like an arch) is one option for minimizing
moisture during storage. Sidewall bundles can also be stored on edge but must be secured so that they
do not fall over and cause injury.
If “white rust” or “wet storage stain” occurs, contact the manufacturer immediately about ways to minimize
the adverse effect upon the galvanized coating.

4. General Information
Bulk Feed Tank Assembly Manual General Instructions
First, read the Assembly Manual completely before starting to assemble your Bulk Feed Tank. Check your
shipment with the packing list to be sure there are no shortages.
1. Decal protective mask must be removed when assembling tank. Mask may become difficult to
remove if left exposed to sunlight.
2. Vertical seams must be staggered on all sidewall rings.
3. When legs extend up 2 rings, the leg holes must be in alignment in the bottom 2 rings.
4. All hopper seams and the hopper collar use truss head bolts. The heads of the bolts must be on the
inside of the tank.
5. Hex head bin bolts are used on all sidewall and roof seams with the bolt heads on the outside of
the bin.
6. Hex head bolts are to be used on all leg to sidewall connections with the bolt heads on the inside of
the tank.
7. All bolts are to be tightened from the nut side only. Do not allow bolt heads to spin.
8. 7' Diameter sidewall sheets must be bolted together so there is 65-5/8" between leg holes.
(See Page 80.)
9. Drift punches can be used to align holes.
10. All vertical sidewall sheet seams must be overlapped in the same direction.
11. A hole spacing of 3-1/8" is used at the top of all top sidewall sheets and at the bottom of all bottom
sidewall sheets.
Selecting the Proper Site
The selected site should be level, firm and free from underlying debris. The tank can be installed
satisfactorily on slopes, but as the slope increases, additional labor and materials are required for the
foundation. The concrete foundation surfaces must be level. If some fill is required, it should be watered
andtamped thoroughlyto preventunevensettling fromtheweightof thetank.Goodwater drainageshould
be provided to prevent water collecting under or around the tank. The site must allow convenient access
for loading and unloading and provide additional space for future units. Also, consider the positioning of
handling equipment, availability of electricity, etc.
Tools
Tools recommended for assembly of Bulk Feed Tanks.
1. Assorted sizes of combination wrenches
2. Hammer
3. 3-12" Long drift punches
4. 1 Large flathead screwdriver
5. 1 Pair of slip joint pliers
6. Two (2) adjustable wrenches
7. Ratchet and sockets
8. Impact wrenches and sockets (if available)
