UNCRATING AND SET UP
1. Read this Manual thoroughly before installation and operation. Do not proceed with installation and
operation if you have any questions or do not understand anything in this Manual. Contact your local
Distributor, or BIRO rst.
2. Remove all banding, shipping carton, and all equipment from inside the tub. Then take machine off
shipping pallet.
3. Install machine on a level, non-skid surface in a well-lighted work area away from children and
visitors.
4. This machine is complete except for knife and plate. There is a bowl shipping plug (cardboard) placed
in the output end of the grinding bowl to retain the grinding auger during shipment. REMOVE THE
BOWL SHIPPING PLUG AND THE GRINDING AUGER.
5. After checking and making sure the power supply is correct, plug in your machine.
NEVER OPERATE MACHINE WITH PRODUCT SAFETY COVER OPEN.

MOTOR WIRING AND ELECTRICAL REQUIREMENTS
2. Connect leads to machine in a manner that will be approved by local electrical inspectors.
3. Rated voltage of the unit shall be identical with full supply voltage.
4. Voltage drop on the supply line shall not exceed 10% of full supply voltage.
5. The feederline conductor size in the raceway from the branch circuit to the unit must be correct to assure
adequate voltage under heavy starting and short overload conditions.
6. The feederline conductor shall only be used for the supply of one unit of the relevant horsepower. For
connections of more than one unit on the same feederline, a local electrician will have to be consulted to
determine the proper conductor size.
7. The size of the electrical wiring required from the power source to the Single phase mixer-grinder/chopper
is a MINIMUM OF No. 10 GAUGE WIRE.
8. The BIRO Manufacturing Company is not responsible for permanent wiring, connection or installation.
PRE-OPERATION AND AUGER ROTATION CHECK
ROTATION MUST ONLY BE CHECKED WITH THE
GRINDING AUGER REMOVED, otherwise serious irreparable
damage may occur to grinding components.
1. Turn the hand/foot selector switch to the hand position. Push the green start button. CHECK THE
ROTATION OF THE AUGER DRIVE SHAFT; ROTATION MUST BE COUNTER-CLOCKWISE as
indicatedbytherotationdecalafxedtothegrindingbowl.
2. If machine runs clockwise (backwards), it must be rewired to correct rotation, otherwise serious irreparable
damage may occur to the grinding components.
3. When supplied, check operation of optional pneumatic footswitch. Plug footswitch cord into female
coupling located on the same side as the operation controls. Move selector switch to foot. The machine will
operate with pressure on the footswitch bellow. Releasing the bellow stops the machine. The footswitch
operates the mix and grind together.
4. Insert auger assembly into grinding bowl, place knife (sharp edges out) onto the square end of the auger
assembly. The breaker plate slides over the worm knife drive pin, and is held from rotating by pins in the
grinder bowl. Install the retaining ring.

Three phasegrindersarewired208/220voltsunlessotherwisespecied.Besuremotorspecications
(voltage,cycle,phase)matchpowersupplyline.Besurevoltageisuptospecication.
The size of the electrical wiring required from the power source to the Three phase mixer-grinder/chopper
is a MINIMUM OF No. 12 GAUGE WIRE.
1. Single phasegrindersarewired208/220voltsunlessotherwisespecied.Besuremotorvariable
frequency drive parameters are adjusted for correct line voltage. Be sure to read line voltage for correct
parameter adjustment. See variable frequency drive manuals for parameter settings.

5. Check placement of all warning labels and be sure anyone who is to operate this MINI-22 MIXER
GRINDER has read and fully understands the operators manual. Machine is now ready for trained operators
to process product.
6.Usemeatdeectorattachedtogrindingbowltoeliminatemeatsplatter.
7. Contact your local distributor if you have any questions or problems with the installation or operation of this
machine.

OPERATOR’S NOTES
ONLY HAND TIGHTEN RETAINING RING
For best results, use knife and plate as a set. Do not operate machine for any
period of time without product in the grinding bowl. This will cause
heating and dulling of the knife and plate.

ELECTRICAL MAINTENANCE

17
DO’s DON’Ts
• Always keep knife & plate as matched set.
• Always keep the knife & plate sharp.
• Always install the knife & plate in correct
sequence, knife 1st, then plate.
• Always inspect the plates making sure all holes
are clear - that there are no cracks.
• Always keep knives & plates lubricated in storage
and when starting machine.
• Always check for straightness by laying the knife
on the plate before inserting in machine.
• Always use coolant when sharpening plates.
• Never, never mix different knives to different plates.
• Never, never over tighten the bowl retaining ring
on the machine.
• Never, never hit the plate against anything to
clean the holes.
• Never, never run the grinder without product.
Product is a natural lubricant. Heat can build up so
fast that cold product could crack the plate.
• Never, never throw the knives & plates.
GRINDER KNIVES & PLATES
SAFETY
Always inspect parts for cracks, heat fractures, discoloring. Never run on parts that have these defects.
Always use O.S.H.A. lockout tagout procedures when changing knives and plates!
Always wear gloves when handling knives and plates.
Never run plates below minimum thickness.
Customer is responsible for safety, installation, and operation of equipment. It is the responsibility of the user to
comply with all O.S.H.A. or A.P.H.I.S. regulations.
IMPORTANT!
USE KNIFE AND PLATE TOGETHER
Always use the same knife and plate together. If one
has gradually worn away from perfect level, the other
will have worn with it. As a result they may still be
used together. If however, one is matched with a
different member which is ground true, the set will
certainly not turn out a good product. In addition, such
practice will probably break the new member.
