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
Sharp Edge Hazard
• This product has sharp edges, which can cause serious injury.
• To avoid injury, handle sharp edges with caution and always use
proper protective clothing and equipment.
ST-0036-2
Store Bin Sheets Properly
• Sidewall bundles or sheets must be stored in a safe manner.
The safest method of storing sidewall bundles is by laying them
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.
ST-0058-2
Stay Clear of Hoisted Equipment
• Always use proper lifting or hoisting equipment when assembling 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.

4. General Information
Bulk Feed Tank Assembly Manual General Instructions
First, read the assembly manual completely before starting to assemble the Bulk Feed Tank. Check the
shipment with the packing list to be sure there are no shortages.
1. Decal protective mask must be removed when assembling tank. Use soapy water to soak the decal
protective mask for 5 minutes to ease removal.
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. Drift punches can be used to align holes.
9. All vertical sidewall sheet seams must be overlapped in the same direction.
10. 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
and tamped thoroughly to prevent uneven settling from the weight of the tank. Good water drainage should
be provided to prevent water collecting under or around the tank. The site must allow convenient access
for loading and unloading and plus 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)
