Maintenance
Virtually the only thing that may limit the useful life of your grain bin is rust.
MFS/YORK/STORMOR has specified a galvanized coating on the steel used to
fabricate your bin that will give many years of service if properly maintained. However,
some rusting over a period of years can be expected with any galvanized products
exposed to the weather. We suggest the following:
1 Do not allow the galvanized surfaces of your bin to become cluttered with
grain or foreign material. As these organic materials deteriorate, they produce
acids that may cause immediate damage to the galvanized coating. Clean
off any such buildups immediately.
2 Check the horizontal surfaces of your bin for any rain water ponding. Dry
and correct the source of ponding immediately.
3 The useful life of bins installed in coastal or acid rain areas may be improved
through periodic rinsing of the exterior surfaces with fresh water.
4 After unloading your bin, any organic material clinging to the interior walls
or floor should be removed.
5 Any large areas of zinc oxidation, commonly called “white rust”, may eventually
lead to deterioration of the base steel itself exhibited by the formation of normal
“red rust”. Small areas of white rust may be periodically repaired by steel
brushing and touch up painting with a wash primer and enamel paint. Large
areas of white rust or any red rusted areas should be repaired by sanding to
base metal and painting with a quality zinc-rich paint.
Besides stopping the premature development of rust, other things you should
periodically check are:
1 Any obvious foundation settlements. Major settlement may cause structural
failure of your bin.
2 Deterioration or looseness of any bolts or fasteners.
3 Continued secure attachment of all sidewall and roof ladders.
4 Proper functioning and attachment of all bin openings such as roof caps.
Be certain all latches and hold down clips are used as intended.
5 If your bin is equipped with a floor, periodically remove the fan transition and
check beneath the floor for the condition of the floor supports, pests, or a
buildup of dust or FM. Clean or repair as required.
6 MFS/YORK/STORMOR strongly suggests that any mechanical or electrical
auxiliary equipment installed in or on the bin be checked on a yearly basis
by a qualified service technician. Consult your dealer for this service as
they are well versed in the care and maintenance of this equipment.

Operating Safety
FOLLOW THESE (4) BASIC SAFETY RULES
Follow the four rules below to make certain that accidents do not occur! Make certain
that everyone working with or around your equipment follows these rules!
1 Be certain that all covers, grates, and guards are in place and securely
fastened before operating!
10
2 Never step or walk on equipment covers grates or guards!
3 Lock out all power before removing covers, grates, or guards! Secure
all chains and belts so that they can’t move before working on any
part of your equipment.
4 Don’t modify or redesign your equipment without first obtaining written
ALL INFORMATION ON THIS PAGE
IS WARNING INFORMATION!
approval from the manufacturer.
Following these 4 basic safety rules is a proven way to reduce accidents! Be certain
to provide all employees working on or near your equipment with effective safety
training, including management.
It is ok to add extra safety rules for your job site but DO NOT SUBSTITUTE other
safety procedures for the 4 safety rules! Following the safety rules given for the safe
use of your equipment requires a commitment at all levels within your company.
SECONDARY SAFETY DEVICES
Devices such as interlock switches, may be helpful but are not fail safe and should
not be substituted for a proper lock out procedure. Do not rely on a switch that
can fail, can lose adjustment or can be bypassed. A proper lock-out procedure will
prevent accidents.
REMEMBER! There is no substitute for a commitment to safety!
OTHER IMPORTANT OPERATING SAFETY CONCERNS
1 Do not make contact with or place body parts near moving parts or moving
equipment! Also remember, do not wear loose clothing near moving parts or
moving equipment!
2 Have a safety program in place for all personnel. Make certain all personnel in your
work area know where all emergency controls and devices are!
3 Work area lighting is part of work area safety!
4 Completely fence off open conveyor(s), hoppers or spouts. Place warning signs
around your fences.
Mfs/Stormor Operator’s Manual 017860 6-09 [1]
2 Safety
Lock-Out
FOLLOW A PROPER LOCKOUT PROCEDURE!
11
1 Shut down the equipment in a normal manner.
2 Shut off energy to the unit at the main power source.
3 Turn the power switch back on to confirm that power has been
deactivated.
4 Attempt to restart the equipment to guarantee that the power is shut off and
then return the switch to the off position.
5 Using your own lock, lockout all (other) energy sources which could provide
any power to the equipment.
6 With your lock in place test the disconnect to make certain the power cannot
be restored.
7 Make absolutely certain that the power can’t be supplied by any means to
the equipment.
8 All authorized personnel must put his/her own personal lock on the switch to lock
it in the off position. Everyone must use only his or her own personal key.
9 Nobody is to return power to the equipment until all work on the unit
has been completed and, all locks have been removed.
Company management needs to look for maintenance or other employees working
on the equipment without following the proper lock out procedure. Management also
needs to look for any cover or guard not in its proper place. It is the responsibility
of everyone to report any missing grates, guards, equipment failures, or failures to
lock out. Make certain that no cover is removed unless power is locked out.

Additional Safety Recommendations
You may decide to buy and install “auxiliary equipment” made by other
manufacturers. MFS/YORK/STORMOR has no control over the design and
manufacture of this equipment. If you buy and install auxiliary equipment, then at
a minimum we suggest that you do the following:
1 Obtain, read, and understand the instructions and cautions of the
auxiliary equipment manufacturer. Be certain all equipment is
installed according to the manufacturers recommendations.
2 Check with MFS/YORK/STORMOR or your dealer. Be certain your bin is
designed to support any additional loads supplied by the auxiliary equipment.
3 Obtain any applicable safety decals from the auxiliary equipment
manufacturer. Display each safety decal in its correct visible location.
4 Make certain all electrical equipment is properly installed and
grounded by a qualified electrician.
5 Check availability and operation of electrical lockout and emergency
stop systems.
6 Be certain all guards or shields are securely in place.
7 Store all operations/maintenance manuals in a safe place available
for future use.
In this and other manuals, shields and guards may have been removed for illustrative
purposes. Do not operate the equipment without shields and guards in place. Failure
to heed this warning may result in serious personal injury or death.
The relatively closed environment of a grain bin may promote the presence of
toxic molds, hazardous dust, or a lack of oxygen. Never enter a bin without proper
respiration equipment and someone else present to watch you.
Heed the suffocation warning decal shown on page 14. Flowing or crusted grain
within a bin can cause a person to become buried and suffocate.
When climbing bin sidewall and roof ladders, take care not to fall into or from the
bin. Common sense dictates that such appurtenances should not be used when
conditions such as rain or wind preclude their safe use. MFS/YORK/STORMOR strongly
recommends that optional climbing equipment be purchased to meet the current
specifications set forth by OSHA or ANSI whether the individual operator is required
by law to do so or not. A properly secured safety belt should be used at all times when
performing operations work or maintenance on the bin roof and sidewall.
Care must be taken to avoid entanglement in equipment installed in or on the bin.
Securely Lock-out all power, be it electrical or PTO, prior to working on or near
such equipment.
Field modification of the bin or auxiliary equipment without the authorization of the
manufacturer may present unknown dangers to the operator and must be avoided.
Do not attempt construction when the weather makes it unsafe! Especially, when
wind conditions are not favorable!

DESIGN CRITERIA
Farm bins are designed to store free-flowing, noncorrosive material with a bulk
density of 50 lbs/ft3 [800 kg/m3] (62 lbs/bushel) or less.
Commercial Bins are designed to store free-flowing, noncorrosive whole grains with
a bulk density of 52 lbs/ft3 [834 kg/m3] (65 lbs/bushel) or less.
All bins are designed to be filled through the center roof opening only, and to be
emptied only from the center. Any off-center unloadings should be used only for
clean-out after discharge has been complete to the angle of repose, through the
center. Sidewall unloading may be done on commercial bins only with a properly
installed grain baffle system. See the instructions on page 25.
Sectional sweep augers with sections no longer than half the radius must be used
on 42’ diameter and larger Farm Bins and 72’ and larger Commercial Bins unless the
Commercial Bin has been specifically upgraded for non-sectional sweep use. The center
section should be completely cleaned out before the next auger section is added.
Have your builder make all non-bin equipment in excess of the company’s
recommendations, like LEGS, WALK-WAYS, SPOUTING and CONVEYORS self
supporting.
ROOF LOAD
NOT CORRECTLY SUPPORTED
ROOF LOAD
CORRECTLY SUPPORTED
Do not overfill the bin roof area. This prevents proper air movement through roof
vents and may also cause roof damage or failure.
Adequate ventilation area must be furnished to match the cubic foot per minute
output of the aeration fan installed on the bin. Some sources recommend a
minimum of 1 square foot exhaust area for every 1000 CFM of air introduced into
the bin. When you run your fans, make certain your VENTS ARE OPEN and
kept clean of all debris and frozen matter. An aeration system can, without
proper management, create a greater load on a roof than equipment or snow and
can damage the bin roof.
Vents are also important for filling bins. Use of vents is required on bins with load/unload
rates in excess of 5000 bushels/hr. Hopper tanks or bins used for load-out require vents
to operate properly.

Important Operation Information
CHECK THE FOLLOWING BEFORE THE FIRST BIN USE
1 All bolts are in place and properly tightened.
2 All ladders, handrails, platforms, and stairways are securely in place.
3 The bin has been properly anchored to the foundation.
4 Unloading equipment operates freely and all control gates are operable.
5 Temperature cables, if used, are fastened to the floor according to the
manufacturer’s recommendation to prevent displacement during filling.
6 The working areas around the bin are clean and free of clutter.
7 All guards and shields are in place.
8 Do not bypass or take shortcuts with electrical safety equipment.
9 Check electrical performance and install lock-outs on equipment.
10 Know who or where to call for immediate help in case of an emergency or injury.
FILLING THE BIN
1 Check that the bin has been cleaned after the last filling.
2 Make certain that everyone is out of the bin before filling the bin.
3 Check to see that the door is closed properly and latched.
4 If temperature cables are used, attach them to the floor with twine or fishing line.
5 Always load the bin at the center fill hole! Off center loading will void the warranty.

USE AND STORAGE
It is beyond the scope of this manual to instruct the operator in proper aeration
procedures. We advise that the operator consult with his state university and
local extension service plus draw on his own experience to best tailor his aeration
operation to suit his needs. Below are several comments that could prove helpful.
1 Proper air exhaust must be provided during fan operation to prevent roof
damage (note decal installed on the outer door panel). We advocate the use
of optional roof vents for this purpose as they are weather tight and pest tight
and allow the operator to keep the roof manway opening closed to weather
during operation. Vents should be regularly inspected to insure that they have
not been obstructed by chaff or ice during cold weather.

2 Grain management is the key to proper drying and aeration of a stored crop.
The fruits of your year’s labor are in your storage bin. The good operator
frequently checks the temperature and moisture content of the grain during
drying and storage operations. The result of these checks allow the operator
to modify his drying and storage procedures before any grain goes out of
condition. MFS/YORK/STORMOR recommends probing for moisture content
and temperature at least once a week during storage.
3 Proper air exhaust openings reduce the amount of condensation that occurs
on the interior of the roof sheets during operations. Condensation should be
periodically checked to insure that dripping into the top grain layer is not severe
enough to cause spoilage.

WORKING CORRECTLY
4 It is normally advisable to aerate grain stored after drying for any period
of time. It is desirable to keep the stored grain within 15° F of the ambient
temperature to reduce moisture migration and resultant heating spoilage.
Most operations, however, will not reduce the grain temperature below
freezing. Reduction of the grain temperature within the bin during the winter
months also reduces insect activity and resulting damage.
5 Certain days are not conducive to aeration as the relative humidity may
exceed the equilibrium moisture content humidity of the stored grain,
theoretically adding moisture back into the kernel. Consult your local
extension service for further information.
Mfs/Stormor Operator’s Manual 017860 6-09 [1]

4 Operator’s Section
6 In areas of the country where ambient temperatures are not low enough to reduce
winter insect activity, it may be desirable to fumigate the stored grain. For proper
and safe fumigation techniques, consult your local extension service.
7 It is always advisable to have three people involved, two on the outside and
one inside, when entering a questionable bin/storage circumstance. The person
in the bin should be secured or fastened to a safety rope with the two persons
outside capable of lifting that person out without entering the bin. One person
outside cannot do this, and cannot go for help and maintain preliminary aid.
8 MFS/STORMOR Bins are designed to accommodate only free flowing grain.
22
Storage of non-free flowing material (such as Soy Bean Meal) will void the
warranty.
9 Only dry grain, not to exceed 15% moisture content, is to be stored in
MFS/STORMOR bins. High moisture content, will go out of condition quickly.
Out-of-condition grain will not flow freely and may cause other problems. Wet
holding bins and hopper tanks are designed to hold wet grain only for short periods
of time (48 hours), such as to feed a dryer. No MFS/STORMOR Bins are designed
to hold wet grain for long periods of time.

10 Drying of grains may only take place in bins specifically designed as drying bins.
Consult your dealer for the type of bin installed. All Farm Bins have a placard inside
the door cover with loading information (including stirring machine usage for the
various bin types.)
11 Fumigation for insect control or mold inhibitors may be applied according to
chemical manufacturer specifications. Liquid chemicals that contain acids or
other corrosive chemicals may void the bin warranty. Check with your Dealer
or Manufacturer before applying liquid fumigant or mold inhibitor.
12 Peak loads are designed to handle the total loads in excess of roof snow loads.
These loads include spouts, catwalks, spreaders, stirring machines and others.
If multiple items are supported by the roof the sum of their weights must be used
to check capacity.
13 Load and unload rates for Farm Bins are listed on the placard on the inside door
cover. Commercial Bins are designed to handle a standard load/unload rate of
15,000 bushels per hour (375 MTPH).
WARNING! Do not enter this bin while it is being loaded
or unloaded!
WARNING! Observe ALL SAFETY PRECAUTIONS IN THIS
MANUAL!
14 When using stirring augers, do not operate them or start them near the bin
sidewall. Stirring augers must be kept at a safe distance from the sidewalls!

UNLOADING THE BIN
1 Grain must be unloaded from the center of the bin to maintain uniform loading
on the sidewalls. Off center unloading may void the warranty of your bin. Center
gates must be opened first and the intermediate sumps must not be used
until all the grain that will has flowed by gravity through the center opening.
If your center sump becomes blocked, consult the MFS/YORK/STORMOR
Engineering Department for unloading recommendations. Heed the warning
decal on page 14 of this manual and on your access doors when unloading.

CENTER UNLOADING & ADEQUATE
VENTS FOR UNLOADING
2 Make certain there are adequate vents installed on your bin to prevent a vacuum
from forming in the upper portion of the bin during bin unloading. The pressures
on the roof caused by such a vacuum could damage or cause structural failure
to your roof.
3 After all grain has flowed by gravity through the center unload sump, it is
acceptable to open and drain the intermediate sumps to create a valley near
the door for installation and starting of a sweep auger.
4 When inside the bin, installing a sweep auger or cleaning, LOCK OUT all unload
equipment power. NEVER enter a bin when unload equipment is operating, as
you may become entangled in the sweep or the unload auger. Failure to heed
this warning may result in serious personal injury or death.
5 MFS/YORK/STORMOR recommends on bins 42’ diameter and larger Farm Bins
and 72’ and larger Commercial Bins where two (2) section sweep augers are
used, that the inner sweep section be used to make a preliminary pass around
the bin prior to using the full length sweep. This will result in more uniform
stresses on the walls and foundation anchorage of these larger bins.
6 Do not unload from the side discharge system and center bottom discharge at the
same time. (Do not use (2) side-discharge systems to unload at the same time.)
Mfs/Stormor Operator’s Manual 017860 6-09 [1]
4 Operator’s Section
Side Draw Discharge System Operation
A Side Draw discharge system is optional on Commercial Bins. Side Draw discharge
systems are only available in stiffened Commercial Bins. Side Draw discharge systems
are only designed to be used with whole, free flowing grains. If your bin has been
designed to accommodate a Side Draw discharge system and if such a system was
installed on your bin, special rules for the operation of your bin must be followed. These
special rules for bins with Side Draw discharge systems are listed below.
25
WARNING! Important Side Draw Instructions to follow!
1 Side draw systems are intended
for use with dry grain only. Don’t
use a side draw with any poorly
flowing products.
2 In multiple systems only one side
draw may be used at any (1) time.
3 A side draw discharge is not
to be considered the primary tank
discharge. A standard center
discharge and conveyor should
be installed.
4 Use of a side draw will leave the
grain in the bin in a sloped
condition, creating eccentric
loads on both the bin wall and the
foundation. Prior to prolonged
storage, the grain should be
leveled by use of the center
discharge to equalize wall
pressures; this will help prevent
differential settlement in the
foundation and deformations in
the bin.
Mfs/Stormor Operator’s Manual 017860 6-09 [1]
5 Before adding any grain to the bin,
make certain the grain is in a
level or cone down position.
6 A side draw system is not
intended to be used as a continuous
fill/empty system.
7 If a wind ring is used in
conjunction with a side draw, field
cut the baffles to allow passage
of the wind ring.
8 The discharge chute must be placed
no lower than the fourth ring from
the bottom. Locating the discharge
chute any lower will void the
warranty on the bin.
9 The top discharge baffle should
start in the second ring from the
top. Care should be taken with
the start of the baffles so that the
discharge chute is not located
on a vertical seam.
