Chapter 1: Safety Precautions
Safety Guidelines for Bins
Safety guidelines must be followed at all times. This manual is written to help you understand safe operat-
ing procedures and problems that can be encountered by the operator and other personnel when using
this equipment. Save these safety guidelines for future reference.
As owner or operator, you are responsible for understanding the requirements, hazards, and precautions
that exist and to inform others as required. Unqualified persons must stay out of the work area at all
times.
Alterations must not be made to the equipment. Alterations can produce dangerous situations resulting in
SERIOUS INJURY or DEATH.
This equipment must be installed in accordance with the current installation codes and applicable regula-
tions, which should be carefully followed in all cases. Authorities having jurisdiction must be consulted
before installations are made.
When necessary, you must consider the installation location relative to electrical, fuel and water utilities.
Personnel operating or working around equipment must 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 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 bun-
dles 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.
CAUTION
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.

signs on your machine. Keep signs in good condition.
Replace missing or damaged safety signs. Be sure new
equipment components and repair parts include the current
safety signs. Replacement safety signs are available from
the manufacturer.

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
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.
ST-0061–1
PNEG-4105D 105 Ft. Diameter Z-Tek Bin 11

Chapter 1: Safety Precautions
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
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 manu-
facturer does not warrant this type of roof damage.
• Adequate ventilation or “makeup air” devices must be pro-
vided for all powered air handling systems.
• The manufacturer does not recommend the use of down-
ward flow systems (suction).
• Severe roof damage can result from any blockage of air
passages.
• Operating fans during high humidity or cold weather condi-
tions can cause air exhaust or intake ports to freeze.
ST-0028–2
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

Chapter 1: Safety Precautions
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
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 pres-
sure 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.

General Information
General information, overview and instructions needed before performing work.
Read this manual carefully. This manual will provide instructions on building the sidewall and stiffeners.
You will also need to consult other instructions in building the bin.
These include, but may not be limited to:
• A stiffener and sidewall gauge layout chart. If such a chart is not included with this manual, contact
GSI.
• Roof instructions must be followed. Roof instructions are included in this manual.
• Ladders, roof stairs, roof handrails and other products are covered by separate instruction manuals.
Consult the appropriate accessory manual. Inside ladder instructions are included in this manual.
• Aeration systems and transitions are to be installed according to the instructions provided with the
system or transition.
• It is critical that the anchor bolts are installed and spaced correctly.
Anchor Bolt Charts
Prior to setting any anchor bolts, you must be sure to have the correct anchor bolt placement. This is very
critical for stiffener alignment during bin erection.
NOTE: Refer to the proper chart to find the anchor chord dimensions that correspond to the bin that is
being built.
Start with one anchor bolt and work from it to the left to locate one quarter of the anchor bolts then to the
right to locate another quarter of the bolts. Working off of the last anchor bolts in each quarter, locate the
remaining anchor bolts in the last two quarters.
