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. The grinding bowl assembly is packed separately in the
crate. Remove the grinding bowl assembly from the carton. Disassemble the grinding bowl. Assemble the
grinding bowl only into the front of the grinder. Insert and screw in tight the bowl lock handle under the grinding
bowl. Be sure that the back flange of the grinding bowl is tight against the front of the machine. Do not install
grinding worm at this time.
4. Install the feed tray to the top of the grinder. After checking and making sure the power supply is correct, plug in
your machine. NEVER OPERATE MACHINE WITHOUT TRAY INSTALLED. (Machine will not run with tray
removed.)
5. Machine must be properly grounded. Use qualified electrician to install according to building codes.
6. Pushbuttons that activate the internal on/off switch are located on the front of the machine. The interlock safety
switch is mounted inside the machine case toward the front and will break contact with the magnetic starter
should the tray be removed.

7. Push the green “ON” button. 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 red “STOP” button.
8. If machine runs clockwise (backwards), it must be rewired to correct rotation, otherwise serious irreparable
damage may occur to grinding components.
9. 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 a pin 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.
