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 23

4. This machine weighs approximately 1,302 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 using the following steps. a. Unbolt leg and turn leg adjusting nut (Item No. 60120) counterclockwise until caster rests on floor. b. Retighten lock nuts 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 THIS MACHINE WITH 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 with 10HP grind motor is a MINIMUM OF No. 6 WIRE.

9. The BIRO Manufacturing Company is not responsible for permanent wiring, connection or installation

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).

10. Install step assembly Part No. 43032 on grinder's frame cross brace. See diagram below.

11. Two green and one red pushbuttons are located on the front of the machine that activate the magnetic contactors that control the mix and grind motors. The magnetic interlock switch is mounted behind the wireway cover located at the top-side of the hopper. It lines up with the magnet attached to the product mixer safety cover. When the safety cover is raised the machine will stop operation. Before initial power is applied for start-up, the product mixer safety cover must be lifted slightly and closed again before pushing the mixer start and/or grinder start push buttons.

12. Push the green start button for grind. CHECK THE ROTATION OF THE AUGER 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 AUGER REMOVED, otherwise serious irreparable damage

may occur to grinding components. Rewire if necessary at the plug.

13. Push the green start button for mix. CHECK ROTATION OF THE MIXING PADDLE; ROTATION MUST BE COUNTER-CLOCKWISE as indicated by the rotation decal located on the paddle front mounting hub. Backwards operation will not allow mixing paddle to feed product to the grinding auger.

14. 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.

15. Check operation of optional footswitch if equipped. Plug footswitch cord into fitting at the bottom of the pushbutton control box. Move toggle selector to foot. The machine will operate with pressure on the footswitch treadle. Releasing the treadle stops the machine. The footswitch operates the mix and grind together.

16. 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.

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

18. Use meat deflector attached to grinding bowl to eliminate meat splatter.

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

CLEANING

ROTATING GRINDING AUGER & ROTATING MIXING PADDLE

TO AVOID SERIOUS PERSONAL INJURY

· ALWAYS Turn Off, Unplug From Power Source and Perform Lockout/Tagout Procedures to This Machine Before Cleaning or Servicing.

· ONLY Use Recommended Cleaning Equipment, Materials, and Procedures.

· NEVER Spray Water or Other Liquid Substances Directly at Motor, Power Switch or any Other

Electrical Components.

· ALWAYS Thoroughly Clean Equipment at Least Daily.

CLEANING THE BIRO MIXER GRINDER

1. Disconnect mixer grinder from power source and perform lockout/tagout procedures.

2. Remove grinding bowl end ring, breaker plate, knife and grinding auger.

3. Remove mixing paddle. Be sure front most paddle arm is pointing up. Loosen the thumb screw on the mixer paddle lock arm (Item No. 53852). 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. The grinding head can be removed for cleaning if desired. This is accomplished by removing the three nuts on the back flange of the grinding head.

6. After machine has been cleaned and allowed to 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 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.

B. MIXING PADDLE INSTALLATION

1. Holding the mixing paddle by the center shaft and with the front blade up carefully fit drive male collar into the end of the drive shaft. Insert paddle lock arm assembly (Item No. 53852) into the front of the mixing tub and onto the front of the mixing paddle.

2. When fully seated, turn the lock arm counterclockwise so the protruding arm is behind the lock set screw bracket. Tighten the mixer paddle lock set screw (Item No. 53568).

C. LUBRICATION

1. MOTORS: The mix and grind motors have pre-lubricated bearings. These bearings should be re-lubricated annually with a good grade of bearing grease. Do not over-grease.

2. BEARING HOUSING: The main bearings are housed in an enclosed and sealed journal box. Re-lubricate semi-annually with a good grade of bearing grease. Do not over-grease. This may cause seal damage.
