Prevent Roof Damage Due to Vacuum Pressure
• Roof damage can result from excessive vacuum or internal
pressure from fans or other air moving systems. The manufacturer
does not warrant this type of roof damage.
• Adequate ventilation or “makeup air” devices must be provided for
all powered air handling systems.
• The manufacturer does not recommend the use of downward flow
systems (suction).
• Severe roof damage can result from any blockage of air
passages.
• Running fans during high humidity or cold weather conditions can
cause air exhaust or intake ports to freeze.
ST-0028-2
Unload the Bin Correctly
• Use CENTER FLOOR OUTLET ONLY until NO grain
remains above this outlet.
• Side floor outlets to be used ONLY when above condition
is satisfied.
• Lock all side floor outlets to avoid accidental premature use.
• See manufacturers instructions for proper use of factory
supplied sidedraw (wall) discharge systems.
ST-0060-1
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.

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
Do Not Enter Bin
• Rotating flighting will kill or dismember.
• Flowing material will trap and suffocate.
• Crusted material will collapse and suffocate.
- If you must enter the bin:
1. Shut off and lock out all power sources.
2. Use a safety harness and safety line.
3. Station another person outside the bin.
4. Avoid the center of the bin.
5. Wear proper breathing equipment or respirator.

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. ST-0047-1
Do Not Overfill the Bin
• Do not overfill bin. Stored grain must be no higher than
the roof eaves at the outer edge.
• Filling the bin above this point creates excessive internal
pressure and can cause swelling and eventual roof
failure. The over filling of a bin can also cause the
blockage of roof vents and eaves, which will lead to a
build-up of air pressure causing roof damage.
ST-0050-1
Install and Operate Equipment Properly
• This product is intended for the use of grain storage only. Any other
use is a misuse of the product.
ST-0057-1
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.

Guidelines for Proper Storage of Grain Bin Materials Prior to
Construction
Storage of the build materials prior to construction is important. Do not to allow moisture to remain
between sheets or panels.
Wetstorage stain(rust)will developwhen closelypacked bundlesof galvanizedmaterial,such assidewall
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.
