TO AVOID SERIOUS PERSONAL INJURY
PROPERLY INSTALL EQUIPMENT IN ADEQUATE WORK AREA
ALWAYS Use Qualified Technician and Electrician for Installation.
ALWAYS Connect to Proper Voltage & Phase.
ALWAYS Install Equipment in Work Area with Adequate Light and Space Away From Children
and Visitors.
ONLY Operate on a Solid, Level, Non-Skid Surface.
NEVER Bypass, Alter, or Modify This Equipment in Any Way From Its Original Condition.
NEVER Operate With Tray Removed.
NEVER Operate Without all Warning Labels Attached and Owner/Operator Manual Available to
the Operator.
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. Install machine on a level, solid, non-skid surface in a well-lighted work area away from children and visitors.
3. This machine is complete except for a knife and plate. There is a bowl shipping plug (stamped steel) placed in
the output end of the grinding bowl to retain the grinding worm during shipment. REMOVE THE BOWL
SHIPPING PLUG AND THE GRINDING WORM.
4. After checking and making sure the power supply is correct, plug in your machine. NEVER OPERATE
MACHINE WITHOUT TRAY INSTALLED.
5. Machine must be properly grounded. Use qualified electrician to install according to building codes.
6. A toggle switch that activates the internal on/off switch is located on the motor junction box.
7. Lift the toggle handle up to “ON” position. CHECK THE ROTATION OF THE WORM DRIVE SHAFT
ROTATION MUST BE COUNTER-CLOCKWISE as indicated by the rotation decal affixed to the grinding bowl.
ROTATION MUST ONLY BE CHECKED WITH THE GRINDING WORM REMOVED, otherwise serious
irreparable damage may occur to grinding components. Push toggle handle down to “OFF” position.
3

8. If machine runs clockwise (backwards), it must be rewired to correct rotation, otherwise serious irreparable
damage may occur to grinding components.
9. Check that the grinding bowl is properly seated and that the bowl lock assembly is tight. Insert worm assembly
into grinding bowl, place knife (sharp edges out) onto the square end of the worm assembly. The breaker plate
slides over the worm knife drive pin, and is held from rotating by pins in the grinding bowl. Put on 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.
10. Check placement of all warning labels and Manual. Machine is now ready for trained operators to process
product.
11. Contact your local Distributor or BIRO directly if you have any questions or problems with the installation or
operation of this machine.
MOTOR WIRING AND ELECTRICAL REQUIREMENTS

on the motor plate or motor outlet box.
(2) All grinders are wired for the voltage as ordered. 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 BIRO Manufacturing Company is not responsible for permanent wiring, connection or installation.

2. Remove grinding bowl end ring, breaker plate, knife and grinding worm.
DO NOT POWER SPRAY DIRECTLY AT ELECTRICAL COMPONENTS
3. 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.
4. The grinding bowl can be removed for cleaning if desired. This is accomplished by unscrewing the bowl lock
assembly.
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.

CLEANING THE BOWL - RING AND WORM
CARE OF TIN COATED PRODUCTS
(DO’S AND DON’TS)
1. Do not clean with 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. Donot use a detergent containing a high percentage of tri-sodium phosphate or meta-silicate.
Tin is reactive to both.
4. Rinse well and dry thoroughly after washing to remove agents that may be reactive to tin.
5. Ifsterilizing agent containing chlorine is used, the tinned surface must be thoroughly rinsed.
Chlorine is corrosive to tin.
6. Dry thoroughly after rinsing and store in a dry environment.
7. Ifwater is exceptionally hard, drying will be necessary to prevent spotting.
