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. After installing machine in operational area, it is imperative that the four adjusting legs be adjusted to level the machine and also eliminate rocking.

4. 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.

5. After checking and making sure the power supply is correct, plug in your machine. NEVER OPERATE MACHINE WITHOUT TRAY AND GUARD INSTALLED (Machine will not run with tray removed).

6. Machine must be properly grounded. Use qualified electrician to install according to building codes.

MOTOR WIRING AND ELECTRICAL REQUIREMENTS

(A) Interchange of current is made in motor outlet box. Leads are properly marked. Changing instructions are

on the motor plate or motor outlet box.

(B) 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.

ALWAYS LEVEL MACHINE BEFORE USING

(D) Rated voltage of the unit shall be identical with full supply voltage.

(E) Voltage drop on the supply line shall not exceed 10% of full supply voltage. (F) 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.

(G) 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.

(H) The size of the electrical wiring required from the power source to the grinder on the 3, 5, 7

HP Grinders is

a MINIMUM OF No. 10 WIRE. On the 10 & 15 HP Grinders a MINIMUM OF No. 8 and No. 6 respectively.

(I) The BIRO Manufacturing Company is not responsible for permanent wiring, connection or installation.

7. Located on the side of the machine is a toggle handle that activates the internal on/off switch. The interlock safety switch is mounted to the top of the internal switch and will break contact with the magnetic starter should the tray be removed.

8. Turn the toggle handle to the “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.

9. If machine runs clockwise (backwards), it must be rewired to correct rotation, otherwise serious irreparable damage may occur to grinding components.

10. 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.

11. Check placement of all warning labels and Manual. Machine is now ready for trained operators to process product.

12. Use meat deflector attached to tray to eliminate meat splatter.

13. Contact your local Distributor or BIRO directly if you have any questions or problems with the installation or operation of this machine.

NOTE TO OWNER AND ELECTRICIAN: IF THIS MACHINE IS NOT CORD AND PLUG CONNECTED TO THE ELECTRICAL SUPPLY SOURCE, THEN IT SHOULD BE EQUIPPED WITH, OR CONNECTED TO, A LOCKABLE, MANUALLY-OPERATED DISCONNECT SWITCH (OSHA 1010.147).
