DO NOT OPERATE OR USE THIS EQUIPMENT UNTIL THE FOLLOWING
OPERATING AND SAFETY INSTRUCTIONS HAVE BEEN READ AND
UNDERSTOOD. FAILURE TO UNDERSTAND AND PRACTICE GOOD SAFETY
PROCEDURES COULD RESULT IN PERSONAL INJURY OR DEATH.
All farm machinery is inherently dangerous to children and to persons unfamiliar with its general
operation. Children should not be permitted in areas where machinery of this nature is operating.
Since mills contain numerous moving parts, some of which may not always be visible to the operator,
they can be extremely dangerous. Steps should be taken to assure the safety of the operator, and
any other people in the area. Automatic Equipment strongly recommends that no person be permitted
to operate this mill without a thorough understanding of how the machine works and the precautions
to be observed.
The operator of this machine should be a responsible adult who is familiar with farm machinery,
and trained in its operation. REMEMBER! Your best insurance against accidents is a careful and
responsible operator. A careless operator is a liability to himself and those who work with him.
Because of the dry, highly ammable material associated with this machine, FIRE FIGHTING
EQUIPMENT SHOULD BE READILY AVAILABLE DURING THE OPERATION OF THIS MACHINE.
Before operating this equipment, be sure to read and understand this operator’s manual. If there is any
portion of the manual, or any phase of the roller mill’s operation you do not understand, be sure to contact
your local Automatic dealer or Automatic Equipment, Pender, Nebraska. 402-385-3051.
SAFETY PRECAUTIONS - BEFORE OPERATION
1. Keep the mill in good repair. Good maintenance is your responsibility. A poorly maintained

any obstruction from the mill. Never try to push or force feed grain or snow
that may be bridged or laying in the hopper.
7. NEVER sit or stand on the mill while it is in operation.
8. NEVER adjust or service the unit while it is in operation.
9. NEVER open shields, mill access doors or clean out doors while the mill is in operation.
10. DANGER Avoid contact between the discharge conveyor and overhead electrical lines. Failure
to heed warnings will result in serious personal injury or death.
11. Hydraulic uid can cause serious burns. Hydraulic uid escaping under pressure can have
enough force to penetrate the skin and may also infect a minor cut or opening in the skin. If
injured by escaping uid, see a doctor at once. Make sure all connections are tight and that hoses
are in good condition.

SAFETY PRECAUTIONS - SERVICE AND REPAIR
1. SAFETY SHUTDOWN PROCEDURE: Working on the mill when it is operating is expressly
prohibited. Never clean, adjust, lubricate, or otherwise service this machine until the following
steps have been taken.
A. Disengage the power source.
B. Lock all switches.
C. Wait until all mechanical motion has stopped on the mill.
Only when these precautions have been taken, should you proceed in the adjustment or servicing
of the mill. Failure to follow the above procedure could lead to death or serious personal injury.
2. Keep the mill in good repair. Good maintenance is your responsibility. A poorly maintained
machine is an invitation for trouble. Always use proper tools when servicing machine, making
certain that they are removed from the unit when services or repairs have been completed.
3. All mills are equipped with shielding to protect the operator from injury. For purposes of clarity
only, some illustrations in this manual may show the mill with the shields removed or missing.
Although shields may be opened or removed for servicing and repair of the mill, they MUST
always be closed or replaced before operation resumes.

ROLLER MILL MAINTENANCE AND OPERATION
Automatic Grain roller mills are manufactured from the best materials and workmanship available -
each has been tested and properly adjusted at the factory before shipping. Simple adjustments and
minimum maintenance have been emphasized. Reasonable care and operation will assure many
years of trouble-free service.
• BE SURE roller mill is mounted on a rm base. The machine should be level while operating so
the grain will ow evenly across the rolls. This will eliminate unnecessary strain on roll bearings
and shafts, and also do a better job of rolling.
• ELECTRIC POWERED UNITS should be operated at about 600 RPM. Use a pulley ratio of 3 to 1
on 1800 RPM motors.
• IT IS IMPORTANT that all units be checked after the rst few hours of service to insure that all
set screws, lock collars, and other hardware has remained secure. This operation should be
performed periodically as part of general maintenance on your roller mill.
• ROLLER TENSION SPRINGS on oating roll are set at the factory to maintain just the right
amount of pressure. NEVER readjust compression spring tension. These springs prevent
stoppage, allowing foreign objects such as nails, bolts, etc. to pass between rolls. On all of our
mills, magnets are available and recommended, as they separate pieces of iron and steel from the
feed. Saving the life of just one animal will pay for several magnet installations.
• HOPPER GATE CONTROL. Your roller mill will not start with grain between rolls. Always start
roller and bring rolls to full RPM before opening feed gate. Make sure feed gate in hopper is
closed before putting grain in hopper. If grain is released to rolls before they are turning, grain will
pile up and it will be necessary to clean out between rolls and run remaining kernels through by
hand before starting.
• ADJUSTING FEED ROLLS from ne to medium or coarse grind, a turn of the handle on the quick-
adjust in the rear of the mill will set your rolls. To move roll inward, remove lock pin, turn quick-
adjust handle counter-clockwise. To move roll outward, remove lock pin turn quick-adjust handle
clockwise. This will assure you of an even and proper setting, adjusting both sides of the roll at
the same time. After the adjustment has been made always lock setting by placing lock pin on the
right side of chain link welded to the end plate
• DON’T OVERCROWD THE ROLLS - keep a ribbon of grain going between the rolls, and you’ll do
a better job of rolling. This is especially true of oats and barley. It is not necessary to completely
atten the kernel. The grain becomes easy to digest when the hard coat or hull is broken open,
exposing the nutrients to the digestive juices.
• BEARINGS - All pillow block and cast ange bearings are sealed and as a general rule, require no
lubrication. However, the bearing manufacturer does furnish grease zerks and recommends the
bearings be re-greased before one-third (1/3) of the bearings’ calculated life elapses. Usually just
a pump or two of grease per bearing before start up each harvest or after the unit has not been
used for a month or more will be sufcient.
IMPORTANT - DO NOT OVER GREASE. Over greasing can cause damage to the bearing seal.
• ROLLER CHAIN - All mill roller chains should be lubricated every 4 hours of normal use. Use a
chain lubricant or the following weight oil:
• REALIGNING ROLLS... If rolls should ever come out-of-alignment, (more gap on one side of
the roll pair than the other side), they must be realigned to maintain feed consistency. This can
be accomplished by rst removing the connecting link, from the quick adjust chain, and then
removing the chain from the sprockets. The rolls can now be brought back into alignment by
turning the quick adjust handle. Check the gap between the rolls with a feeler gage and turn the
quick adjust handle until the gap is equal at both ends of the roll pair.
Replace the chain and connecting link previously removed, to complete the procedure

Your roller mill is designed to eliminate complicated adjustments. There are only two (2) major points
of adjustment for any small grain or shelled corn - roller spacing and hopper control gate.
1. HOPPER GATE. Open feed gate gradually until you reach the maximum ow of grain that power
will handle. If it becomes necessary to stop the machine at any time before hopper is empty, be
sure to close the feed door before shutting off power.
2. ROLLER SPACING. This depends upon the type of grain to be rolled. Different grain varies in
size, shape, toughness and moisture content. This is also true of the same kind of grain from
different localities. For this reason, it is impossible for us to tell you how to set the rolls. Do not
over-roll hard or dry grains, as this will cause dusting. Remember, proper adjustment keeps dust
at a minimum, even when rolling the driest grain.
The closest roll setting is preset at the factory and as a rule and should not require additional
adjustment. However, for certain types or conditions of rolling, some “ne tuning” may be required.
IMPORTANT - Check to make sure the roll teeth do not come in contact with each other by turning
the mill by hand after each adjustment.
When ordering parts for your mill, please state your needs with the following information:
MODEL NO. SERIAL NO. PART NO. DESCRIPTION
LPM-200 x 4 000000 101-2467 Shim, 20 Ga
When you order in this way, you can be certain the correct part will be delivered in the shortest time possible.
IMPORTANT: Use only genuine factory replacement parts on your mill. Do not substitute homemade or non-
typical parts. If a bolt is lost or in need of replacement, for your safety and the preservation of your mill, be sure
to use a replacement bolt of the same grade (Usually Grade 5).
