2. Safety
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 which may be
encountered by the operator and other personnel.
As owner and/or operator, you are responsible to know what requirements, hazards and precautions
exist 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 po wer line locations or ele ctrical 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.
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.
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 store d 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.

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 auger. 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.

2. Safety
Proper Storage Grain Bin/Silo Materials Prior to Construction
Wet storage stain (rust) will develop when closely packed bundles of galvanized material, such as
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 tacking and spacing materia ls 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.

3. Decals
The manufacturer does not warrant any roof damage caused by excessive vacuum or internal
pressure from fans or other air moving systems. Adequate ventilation and/or “makeup air”
devices should 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/cold weather conditions can
cause air exhaust or intake ports to freeze.
CAUTION!
Excessive vacuum (or pressure) may
damage roof. Use positive aeration
system. Make sure all roof vents are
open and unobstructed. Start roof
fans when supply fans are started.
Do not operate when conditions exist
that may cause roof vent icing.

Roof Stair with Transition Assembly Instructions (72'-105')
1. Begin assembly at the bottom eave of the roof with the bottom three (3) step section,
part #LDRbracket and the roof rib, then fasten with 5/16" x 1-1/4" bolts and nuts.
2. Follow up the bottom three (3) step section (LDR-5129) with intermediate three (3) step sections
(LDR-4210). Continue adding intermediate three (3) step sections (LDR-4210) until you are within
72" of the roof transition. At this point, measure the distance remaining to pass the roof transition
and decide whether the two (2) step section (LDR-4211) will fit best above or below the four (4) step
transition section (LDR-4406). Figure 10A on Page 32 shows the two (2) step section below the
four (4) step transition sections. If the distance is more than 48", the two (2) step section (LDR-4211)
will most likely fit better below the four (4) step transition section (LDR-4406).
3. After the two (2) step section (LDR-4211) and the four (4) step transition section (LDR-4406) have
been utilized, continue attaching intermediate three (3) step sections (LDR-4210) towards the peak
of the roof. (See Figure 10B on Page 33.)
4. The last section attached at the peak of the roof should be the top four (4) step section (LDR-42 39).

2. Follow up the bottom three (3) step section (LDR-5129) w/ twelve (12) intermediate three (3) step
sections (LDR-4210). At this point, the four (4) step transition section (LDR-4406) should be placed.
NOTE: The 135' package does not include a two (2) step section. (See Figure 10A on Page 32.)
3. After the four (4) step transition section (LDR-4406) has been utilized, continue adding intermediate
three (3) step sections (LDR-4410) towards the peak of the roof. (See Figure 10B on Page 33.) The
135' roof requires five (5) more intermediate sections to be placed after the transition section.

1. Loosely assemble five (5) handrail posts (LDR-4332) with upper (LDR-5120), lower and
intermediate (LDR-5121) handrails connecting the posts as shown in the typical post view
on Page 35.
2. Loosely assemble entrance posts (LDR-4337) to the handrails using the upper L.H. (LDR-4335)
and R.H. (LDR-4334) brackets and four (4) lower brackets (LDR-4336) as shown in the entrance
view on Page 35.
3. Field fitting must be done to connect the entrance posts to the upper post of the top four (4) step
stair package. Cutting and field drilling on LDR-4338 and LDR-4339 is required for a good fit.
4. The flattop handrail posts should be equally spaced on the flattop as shown in the upper view
on Page 35. Detail A on Page 35 shows the welding procedure required to fit the posts to the flattop.
5. Be sure and tighten all hardware. NOTE: 5/16" Hardware is used in all for all connections.
Use a 5/16" washer for slotted connections.
NOTE: Because of catwalks and conveyors, altering of the handrail may be required. Posts may need
to be excluded if this is the case. Longer of shorter field fabr icated handrails may be required to
ensure the handrail wraps completely around the flattop. Paint any non-galvanized surfaces (for
instance, welds) to ensure rusting is kept to a minimum.
