grinding bowl.
2. FIRST GRIND
3. SECOND GRIND
4. Unplug machine from power source and perform lockout/tagout procedures.
a. Fill product hopper (maximum 150 pounds), close product mixer safety cover.
b. Push the mix green start button only.
c. After the desired mix, press green grinder start button to operate the grinding auger and grind out
the product.
b. Push both grind and mix green start buttons to feed rst grind. It is recommended to use a breaker plate
with a ⅜” diameter or larger holes.

MAINTENANCE
A. GRINDING BOWL INSTALLATION
1. Mount the grinding bowl on the two threaded studs on the front of the machine. Tighten in position with
provided nuts.
2. Place the grinding auger in the grinding bowl and fully seat rear drive tang into auger drive shaft.
3. Install knife, breaker plate, and end retaining ring.
ONLY HAND TIGHTEN RETAINING RING
B. LUBRICATION
1. MOTOR: The grinder motor has pre-lubricated, sealed motor bearings.
2. ROLLER CHAIN AND DRIVE SPROCKETS: The main drive chain has been pre-lubricated at the factory
to protect it against dirt and moisture. Chain life will vary appreciably depending upon lubrication. The
better the lubrication, the longer the chain life.
Lubrication effectiveness will vary with the amount of lubricant and frequency of application. Ideally, a
luricant lm should always be present between the working parts. Manually lubricate the chain as often as
is needed (possibly once a week). NEVER exceed three months without lubricating.
Lubricating just the outside of the chain does little good. Apply lubrication on the inside of the chain span
so that it will work through the moving parts and joints by centrifugal force as the chain rotates and reaches
the area where one surface “scrubs” another.
7
ROTATING GRINDING AUGER
TO AVOID SERIOUS PERSONAL INJURY
• ALWAYS Turn Off, Unplug Machine From Power Source and Perform Lockout/Tagout
Procedure to this Machine BEFORE Attempting to Unjam or Unclog, Cleaning or Servicing.
• NEVER Touch This Machine without Training and Authorization by Your Supervisor.
• NEVER Place Hands into Machine Input or Output Openings.
• NEVER Bypass, Alter, or Modify This Equipment in Any Way From Its Original Condition.
• PROMPTLY REPLACE Any Worn or Illegible Warning Labels.
• USE ONLY GENUINE BIRO Parts and Accessories Properly Installed.
4. When the bowl assembly is mounted and tight, there should be approximately ⅛” gap between the back
inside wall of the grinding trough and the back of the auger. The bowl ring wrench which is provided with
each grinder is used for REMOVAL of the end retaining ring for cleaning purposes or for changing knife
and breaker plate.

B. LUBRICATION continued
3. BEARING HOUSING: The main bearings are housed in an enclosed and sealed journal box. Re-lubricate
semi-annually with a good grade of bearing grease. Do not over-grease.
4. MIXER TRANSMISSION: Oil in the mixer transmission should be changed after the rst four (4) weeks
of operation. This is to remove the “run-in” oil and also any small metal shavings that may have been
generated during the mating of the gears. After the intial oil change, subsequent changes should be
performed every six (6) months. After draining the oil, rell the unit to the “level” plug on the back side
of the transmission with petroleum-based #8 gear oil.
5. PROCEDURE FOR REPLACING OIL IN WINSMITH MIXER TRANSMISSION:
a. Unplug mixer/grinder from power source and perform lockout/tagout procedures.
b. Remove rear drive or access cover.
c. Remove breather plug from top of transmission and oil level plug from back side of transmission.
e. When all oil has drained, clean the drain plug and replace in the transmission.
f. Rell transmission with petroleum-based #8 gear oil or equivalent until oil appears at bottom of oil
level hole. For applications that involve severe ambient temperature extremes, Winsmith recommends
the use of Synthetic Lubricants such as: Texaco Vanguard 460, Mobile SHC 630, and Mobile SHC 634.
These gear reducers contain 0.9 QT. of lubricant.
d. With a container in place to catch old oil, remove the drain plug from the bottom of the transmission.
g. Replace breather and oil level plugs.
h. Reinstall rear drive or access cover.
C. MIXER DRIVE CHAIN TENSION
1. Unplug mixer/grinder from power source and perform lockout/tagout procedures.
2. Remove rear drive or access cover.
3. Loosen the four bolts holding the ¾ HP motor and transmission to its mounting plate.
4. Slide transmission to the right.
5. When approximately ⅛” total chain ex has been attained, retighten transmission bolts.
6. Reinstall rear drive cover or access cover.
D. MAIN DRIVE CHAIN TENSION
5. To Loosen Chain Tension. Turn motor adjusting studs counterclockwise. Grasp motor and pull toward
adjusting stud. Be sure to turn both adjusting studs the same amount and evenly. Total chain ex should be
⅛ to ⅜”. Be sure to keep motor shaft parallel with auger drive shaft.
8
a. Unplug mixer/grinder from power source and perform lockout/tagout procedures.
b. Remove rear drive or access cover.
c. Spray or brush lubricant on inside of chain, slowly and carefully turning the large sprocket by hand.
d. Reinstall rear drive cover.
Recommended types of chain lubricant are those with Molybdenum Disulphide or Graphite added. Also
bonded lubricants such as Dow Corning Molykote 321R or equivalent are excellent for open chains. The
lubricant should be of a viscosity whereby it will “ow” somewhat and penetrate the internal working
surfaces. Thick stiff greases are of little value because they cannot work into moving parts of the chain.
1. Unplug mixer/grinder from power source and perform lockout/tagout procedures.
2. Remove rear drive or access cover.
3. Loosen the four bolts that hold the motor to the frame of the machine.
4. Loosen the lock nuts on the motor adjusting stud.

9
To Tighten Chain Tension. Turn motor adjusting studs clockwise. Be sure to turn both adjusting studs the
same amount and evenly. Total chain ex should be ⅛ to ⅜”. Do not overtighten chain as this will put
excessive and damaging pressure on the motor bearings. Be sure to keep motor shaft parallel with auger
drive shaft.
6. Retighten motor mounting bolts.
7. Retighten motor adjusting stud lock nuts.
8. Reinstall rear drive cover or access cover.

“EAGLE” DRIVE SYSTEM
Tensioning Instructions
1. Place a straight edge on top of the belt and across both sprockets as shown in the diagram.
2. Set the large O-Ring at the 1st Graduation (⅛” line) on the Tension Tester,
Item No. H384-EAGL-TSTR.
3. Set the small O-Ring on the deection force scale to ZERO.
4. Place the tension tester squarely on the belt at the center of the belt span (see Diagram).
c. Retighten the motor mounting bolts.
Do not rely on “feel” for the proper belt tension as this typically results in belts that are
under-tensioned.
Loose belts will fail due to “ratcheting” (jumping a tooth), tooth shearing, and breakage.
5. Apply a force to the plunger until the large O-Ring is even with the bottom of the straight edge which has
been laced across both sprockets (⅛” belt deection).
6. Remove the tension tester and read the force recorded from the bottom of the small O-Ring on the force
scale.
7. The force should be equal to the value indicated in the force table #1-7 depending on the “HP” of the
grinder, and if the belt is “new” or “used.”
8. If the force values do not equal those shown in table #1-7, increase the tension as follows:
a. Loosen the 4 motor mounting bolts slightly.
A
b. Advance the jacking screw ¼ turn each (be sure to advance both screws an equal amount).
B
d. Re-check the belt tension according to the above procedure.
Note- The “Eagle” drive belts do not stretch. However, there is a “break-in” period where the teeth in the
belt “mesh” with the teeth of the sprockets during the 1st few hours of operation.
The belt should be re-tensioned after 1 week of operation, according to this tensioning procedure.
No further maintenance is required after this initial adjustment.

LUBRICATION FOR GROVE GEAR REDUCER
1. Factory Filling
The speed reducers are oil lled at the factory to the proper level for the standard mounting position. The oil level
should be checked and adjusted (if necessary) prior to operation, using the oil level plug provided and while the unit is
oriented in its operating position.
2. Oil Changing
OIL SHOULD BE CHANGED MORE OFTEN IF THE
REDUCER IS USED IN A SEVERE ENVIRONMENT
(i.e., DUSTY, HUMID)
Therefore, when changing to a different oil, it is recommended that the housing be completely drained and thoroughly
ushed with a light ushing oil prior to relling with the appropriate lubricant. The oil level should be rechecked
after a short period of operation and adjusted, if necessary.
A. Initial Oil Change
The oil in a new speed reducer should be changed at the end of 250 hours of operation. (30 days for 8 hour per day
service, 15 days for 16 hour service, 10 days for 24 hour service.)
All standard reducers ordered from the factory are lled with lubricant to operate within a 30° to 100° F ambient
temperature range.
B. Subsequent Oil Changes
Under normal conditions, after the initial oil change, the oil should be changed after every 2500 hours of operation,
or every six months, whichever occurs rst. Under severe conditions (rapid temperature changes, moist, dirty, or
corrosive environment) it may be necessary to change oil at intervals of one to three months. Periodic examination
of oil samples taken from the unit will help establish the appropriate interval.
C. Synthetic Oils
3. Overlling or Underlling
If a speed reducer is overlled with oil, the energy in churning the excessive oil can result in overheating. If this occurs,
shut down the drive, remove the oil level plug and allow oil to drain until oil ceases to drain from the level hole,
reinstall the oil level plug and restart the drive. If the speed reducer is underlled, the resultant friction can cause
overheating and possible damage. If this occurs, ll the speed reducer to the oil level plug hole and check the gearing
for excessive wear. NOTE: Oil capacity is 1¾ pints.
4. Oil Seals
A. When installing a new seal, cover the keyway and any other surface discontinuity with smooth tape to protect the
seal lip from being damaged.
B. A sealant should be used between the O.D. of the seal and the I.D. of the bore into which the seal is installed. The
seal bore should also be free of any burrs, nicks, or scratches.
C. Be sure that the seal is not cocked in the bore. The outer face of the seal should be ush with the surface into which
it is mounted.
WHEN CHANGING OIL FOR ANY REASON,
DO NOT MIX DIFFERENT OILS IN THE REDUCER.
OILS SHOULD BE COMPATIBLE WITH
VITON SEAL MATERIAL.
®
Synthetic lubricants can be advantageous over mineral oils in that they generally are more stable, have a longer life,
and operate over a wider temperature range. These oils are appropriate for any application but are especially useful
when units are subjected to low start-up temperatures or high operating temperatures. Use of synthetics can cause
problems if they are not compatible with the seals or the conventional lubricants they replace. For continuous duty
at normal ambient temperatures (-10° to 105°F) we recommend the use of Mobile SHC 634 which is compatible
with the standard compounded oil shipped in our product and the Viton seal material used through size 252.
®
Although the speed reducer uses high quality oil seals and precision ground shafts to provide a superior seal contact
surface, it is possible that circumstances beyond the speed reducer’s control can cause oil seal leakage (damage during
shipment or installation, etc.) When replacing a shaft oil seal, using the following suggestions will help to insure leak-
free operation and long seal life:
