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
first.
2. Remove all banding, shipping carton, and all equipment from inside the tub. Then take machine off shipping
pallet.
3. This machine is shipped with the adjustable legs fully retracted. The legs allow for a height adjustment from the
floor to centerline of bowl 24
1
2
" minimum to 34" maximum.
4. This machine weighs approximately 600 pounds. To avoid accidents block up machine after raising to desired
operating height.
5. The adjustable legs can now be unbolted and lowered to the floor. Replace bolts and tighten securely.
6. Install machine on a level, non-skid surface in a well-lighted work area away from children and visitors.
7. This machine is complete except for knife and plate. There is a bowl shipping plug (stamped steel) 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.
8. After checking and making sure the power supply is correct, plug in your machine. NEVER OPERATE
MACHINE PRODUCT MIXER SAFETY COVER OPEN. (Machine will not run with cover open.)
9. Machine must be properly grounded. Use qualified electrician to install according to local building codes.

MOTOR WIRING AND ELECTRICAL REQUIREMENTS
1. Interchange of current is made in motor outlet box. Leads are properly marked. Changing instructions are on
the motor plate or motor outlet box.
2. All grinders are wired 220 volts unless otherwise specified. Be sure motor specifications (voltage, cycle, phase)
match power supply line. Be sure line voltage is up to specification.
3. Electrical connections to be in accordance with safety codes and National Electrical Code.
4. Rated voltage of the unit shall be identical with full supply voltage.
5. Voltage drop on the supply line shall not exceed 10% of full supply voltage.
6. 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.
7. 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.
8. The size of the electrical wiring required from the power source to the mixer grinder is a MINIMUM OF No. 10
WIRE.
9. The BIRO Manufacturing Company is not responsible for permanent wiring, connection or installation

10. Located on the side of the machine are a green and red pushbutton for activating the internal motor control
contactor. The magnetic interlock switch is mounted under the rear machine cover. It lines up with the magnet
attached to the product mixer safety cover. When the safety cover is raised the machine will stop operation.
11. Push the green start button. CHECK THE ROTATION OF THE MIXING PADDLE; ROTATION MUST BE
COUNTER-CLOCKWISE as indicated by the rotation decal affixed to the mixer paddle front mounting hub.
Backwards operation will not allow mixing paddle to feed product to the grinding auger efficiently
12. Lift slightly the clutch arm and push to the rear of the machine. CHECK ROTATION OF THE AUGER
DRIVESHAFT; ROTATION MUST BE COUNTER-CLOCKWISE as indicated by the rotation decal located on
the grinding bowl. ROTATION MUST ONLY BE CHECKED WITH THE GRINDING AUGER REMOVED,
otherwise serious irreparable damage may occur to grinding components.
13. If machine runs clockwise (backwards), it must be rewired to correct rotation, otherwise serious irreparable
damage may occur to grinding components. Both the auger and the mixing paddle must operate in the same
direction.
14. Check operation of optional footswitch if equipped. Plug footswitch cord into fitting on control panel. Turn
selector lever to foot. The machine will operate with pressure on the footswitch treadle. Releasing the treadle
stops the machine.
15. 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 grinding
bowl. Install the retaining ring.
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.
16. Check placement of all warning labels and Manual. Machine is now ready for trained operators to process
product.
17. Use meat deflector attached to grinding bowl to eliminate meat splatter.
18. Contact your local Distributor or BIRO directly if you have any questions or problems with the installation or
operation of this machine.

paddle lock arm (Item No. 53853). While supporting the mixing paddle, remove the lock arm. Turn the mixing
paddle counterclockwise, slide forward to disengage from drive shaft and lift from product hopper.
DO NOT POWER SPRAY DIRECTLY AT ELECTRICAL COMPONENTS
4. Machine is now ready to be cleaned using warm soapy water and rinsed with clean water. Machine may be
cleaned by power spray washing, taking care to not spray directly at any electrical controls.
5. After machine has been cleaned and allowed to air dry, all exposed metal surfaces should be coated with a good
food grade light oil or grease.

DON’Ts
•
Never, never mix different knives to different
plates.
•
Never, never over tighten the bowl retaining ring
on the machine.
•
Never, never run the grinder/mincer without prod-

1. Do not use abrasive cleaning materials, such as brillo pads or metal scrapers. Tin is a soft metal and should be
cleaned with a soft cloth and dried.
2. Do not use a cleaning agent containing a high percentage of free alkali or acid.
3. Do not use a detergent containing a high percentage of tri-sodium phosphate or meta-silicate.
Tin is reactive to both.
4. Rinse well and dry throughly after washing to remove agents that may be reactive to tin.
5. If sterilizing agent containing chlorine is used, the tinned surface must be throughly rinsed.
Chlorine is corrosive to tin.
6. Dry throughly after rinsing and store in a dry environment.
7. If water is exceptionally hard, drying will be necessary to prevent spotting.
