11. After checking and making sure that the power supply is correct, plug in your machine.
12. Machine must be properly grounded. Use qualified electrician to install according to local building codes.
13. With rear motor cover removed and chute cover in the closed position, push the green “start” button located on
the side of the rear cover. Be sure that the motor and transmission are rotating in the proper direction. Should
be COUNTERCLOCKWISE when viewing the transmission output shaft and machine crank arm, as indicated by
the arrow on crank arm. Should machine be operating backwards, push red “stop” button. Disconnect machine
from incoming power source and interchange two lead wires.
14. When machine is operating in proper direction, replace rear motor cover. Machine is now ready for trained
operators to process product.
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 chippers 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 frozen block chipper is a MINIMUM OF
No. 10 WIRE if the distance from the machine to electrical box is 25 feet or less. Over 25 feet a MINIMUM OF
No. 8 WIRE is to be used.
(9) The BIRO Manufacturing Company is not responsible for permanent wiring, connection or installation.

OPERATION
MOVING SHUTTLE WITH SHARP CHIPPING BLADES
TO AVOID SERIOUS PERSONAL INJURY
·ONLY Properly Trained Personnel Should Use This Equipment.
·ALWAYS Keep Hands Clear of Sharp Chipping Blades and Other Moving Parts.
·NEVER Operate With Product Chute Cover in the Open Position.
·DO NOT Tamper With or Remove Product Chute Cover.
·ALWAYS Close Product Chute Cover Completely Before Operating Machine.
·DO NOT Tamper With, Bypass, Alter, or Modify This Equipment in Any Way From Its Original
Condition.
·ALWAYS Turn Off, Unplug from Power Source and Perform Lockout/Tagout Procedure to This
Machine Before Cleaning or Servicing, or When Not in Use.
·NEVER Leave Unattended While Operating.
·NEVER Operate Without All Warnings Attached.
A. TO PROCESS PRODUCT
1. Place Meat Lug under machine to catch chipped product.
2. Prepare for processing a 60 pound tempered meat block. For optimum chipping the recommended block
temperature is 15 to 25 degrees F. With a maximum block size of 8" ´1612"´1912". This will yield finished
product chips approx. 312"´312"´14". For narrower meat blocks there is available an optional Chute Filler
Plate (Item No. 51526).
3. Lift the Chute Cover slightly to release the Chute Support. Close the chute cover completely. The magnet
attached to the chute must contact the safety switch. The machine will not operate with the Chute Cover in
the open position.
4. Push the green “START” button. When the machine is finished chipping, which should be approx. 60
seconds, push the red “STOP” button. Unplug machine from power source and perform lockout/tagout
procedures.
5. Remove meat lug from under machine. Product is now ready for grinding or mixing/grinding.
