MAINTENANCE

ROTATING GRINDING AUGER

TO AVOID SERIOUS PERSONAL INJURY

� ALWAYS Turn Off, Unplug From Power Source and Perform Lockout/Tagout Procedure to

This Machine BEFORE 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.

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

4. When the bowl assembly is mounted and tight, there should be approximately

1

8

" 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 only for REMOVAL of the end retaining ring for cleaning purposes or for changing knife
and breaker plate.

B. LUBRICATION

1. MOTOR: The grinder motor has pre-lubricated motor bearings. These bearings should be re-lubricated
annually with a good grade of bearing grease. Do not over-grease.

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 its 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
lubricant film 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

B. LUBRICATION (cont.)

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. e
lubricant should be of a viscosity whereby it will “flow” somewhat and penetrate the internal working surfaces.
ick stiff greases are of little value because they cannot work into moving parts of the chain.
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.

3. BEARING HOUSING: e 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 first four (4) weeks of
operation. is 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 initial oil change, subsequent changes should be performed every
six (6) months. After draining the oil, refill the unit to the “level” plug on the back side of the transmission
with pertoleum-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.
d. With a container in place to catch old oil, remove the drain plug from the bottom of the transmission.
e. When all oil has drained, clean the drain plug and replace in the transmission.
f. Refill transmission with pertoleum-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 Lubricant such as: Texaco Vanguard 460, Mobile SHC 630, and Mobile SHC 634. ese gear
reducers contain 0.9 QT. of lubricant
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 cover or access cover.

3. Loosen the four bolts holding the ¾HP motor and transmission to its mounting plate.

4. Slide transmission to the right.

5. When approximately 1/8” total chain flex has been attained, retighten transmission bolts.

6. Reinstall rear drive cover or access cover.

D. MAIN DRIVE CHAIN TENSION

1. Unplug mixer/grinder from power source and perform lockout/tagout procedure.

2. Remove rear drive cover 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.
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 flex should be
1/8“ to 3/8“. Be sure to keep motor shaft parallel with auger drive shaft.
To Tighten Chain Tension. Turn motor adjusting studs clockwise. Be sure to turn both adjusting studs the
same amount and evenly. Total chain flex should be 1/8“ to 3/8“. 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 the rear drive cover or access cover.

LUBRICATION FOR GROVE GEAR REDUCER

1. Factory Filling

The speed reducers are oil filled 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

WHEN CHANGING OIL FOR ANY REASON,

DO NOT MIX DIFFERENT OILS IN THE REDUCER.

OILS SHOULD BE COMPATIBLE WITH

VITON

®

SEAL MATERIAL.

Therefore, when changing to a different oil, it is recommended that the housing be completely drained and
thoroughly flushed with a light flushing oil prior to refilling with the appropriate lubricant. The oil level should
be rechecked after a short period of operation and adjusted, if necessary.

OIL SHOULD BE CHANGED MORE OFTEN IF THE

REDUCER IS USED IN A SEVERE ENVIRONMENT

(i.e., DUSTY, HUMID)

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 filled 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 first. 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

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°F 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.

3. Overfilling or Underfilling

If a speed reducer is overfilled with oil, the energy used 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 underfilled, the
resultant friction can cause overheating and possible damage. If this occurs, fill 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

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.

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 seal bore. The outer face of the seal should be flush with the

surface into which it is mounted.
