SECTION 2.0 DESIGNATED USE
2.1 Warning
WARNING
WHIZARD TRIMMERS ARE USED FOR REMOVAL
OF FAT AND TISSUE, THE RECOVERY OF LEAN MEAT
FROM FAT AND AS AUNIVERSAL CUTTING TOOL
IN THE MEAT INDUSTRY. ANY USE IN APPLICATIONS OTHER
THAN THOSE FOR WHICH THE WHIZARD TRIMMERS HAVE BEEN
DESIGNED AND BUILT MAY RESULT IN SERIOUS INJURIES.
WARNING
THE MANUFACTURER ASSUMES NO LIABILITY FOR ANY
UNAUTHORIZED DESIGN CHANGES, MODIFICATIONS, OR USE OF
PARTS NOT SUPPLIED BY THE MANUFACTURER
OR
THE USE OF PARTS NOT DESIGNED FOR USE
ON THE SPECIFIC MODEL
AND
INCLUDES CHANGES IN OPERATING PROCEDURES
MADE BY THE OWNER OR ANY OF HIS PERSONNEL.
THE USE OF PARTS OTHER THAN THOSE LISTED IN THE PARTS
LIST OF THIS MANUAL MAY CAUSE BLADE LOCK-UP RESULTING
IN AN UNSAFE OPERATING CONDITION.
FOR SAFE AND PROPER OPERATION, READ ENTIRE
MANUAL BEFORE USING THIS EQUIPMENT.

SECTION 3.0 FUNCTION
3.1 Machine Functions
This universal motor drive unit features a 1/3 HP motor which will drive all
current electric Whizard Trimmers with all the advantages, the power, and with all
the performance to improve your yields and profits.
A vertical motor drives a flexible shaft. The flexible shaft drives a rotating blade
in the handpiece via a gear and pinion. The force to cut through meat and fats is
now provided by the drive motor and no longer by the worker. Forces applied by
the worker are greatly reduced and limited to guiding the rotating knife blade.
The design locks the handpiece in the hanger and shuts the motor off when the
handpiece is placed in the hanger.
The motor will not start if the handpiece is in the hanger. An emergency slap-stick
stops the unit.
The handpiece has no metal to metal contact with the motor.
3.2 Safety Recommendations And Warnings
WARNING
ALWAYS TURN OFF THE MOTOR AND PLACE THE HANDPIECE IN
THE HANGER BRACKET. NEVER LAY THE HANDPIECE DOWN ON
THE WORKSTATION OR LET IT HANG FREE BY THE FLEX SHAFT
CASING. NEVER PLACE THE HANDPIECE IN THE HANGER WHILE
THE BLADE IS STILL REVOLVING.

3.2 Safety Recommendations And Warnings (Continued)
WARNING
ALWAYS DISCONNECT THE POWER
AND REMOVE THE TOOL FROM THE
FLEX SHAFT PRIOR TO SERVICING.
WARNING
IF AT ANY TIME THIS MACHINE DOES NOT APPEAR TO OPERATE
NORMALLY OR EXHIBITS AMARKED CHANGE IN
PERFORMANCE, IT SHOULD BE IMMEDIATELY SHUT DOWN AND
TAGGED AS "UNSAFE" UNTIL SUCH TIME AS PROPER REPAIRS
ARE MADE THE MACHINE AGAIN OPERATES NORMALLY.
WARNING
AVOID USE OF THIS MACHINE IN STANDING WATER.

OPERATING BETTCHER MODEL UN-84 MOTOR
INSTRUCTIONS INDUSTRIES, INC. Rev. October 17, 2011
Page 6
SECTION 4.0 SAFETY FEATURES
The sealed enclosure is extremely water resistant with only one small vent hole.
Switch mechanism is located on top of the motor and is completely enclosed under
the motor cover for protection from moisture.
Bottom mounted extra long on/off switch rod.
Strain relief design allows motor to be free-swinging.
The machine has an interlock on the handpiece hanger that prevents hanging the
handpiece while the motor is running or turning the motor on while the handpiece
is in the hanger. The motor will shut off automatically if the handpiece is placed
into the hanger.
SECTION 5.0 INSTALLATION
Correct installation is extremely important to achieve maximum efficiency for
both the Whizard Trimmer unit being used and the operator. Incorrect installation
may possibly hamper the operator's movements and cause undue wear or damage
to the flex shaft and flex shaft casing parts of the unit.
5.1 Space Requirements
CAUTION
IT IS STRONGLY RECOMMENDED THAT ASAFETY CABLE OR CHAIN BE
INSTALLED THROUGH THE SUPPORT YOKE AND AROUND AFIXED
OVERHEAD STRUCTURE.
A 3/4" diameter pipe should be fastened to an overhead beam with the pipe
centerline 12 inches (300mm) to the right of the operator's shoulder for a right-
handed operator (or 12 inches (300mm) to the left of the operator's shoulder if the
operator is left-handed). Pipe centerline for Small Tool Models should be 12
inches (300mm) back from the front edge of the table and 15 inches (380mm)
back from the front edge of the table for the Large Tool Models (see Figure 1).
The pipe should be long enough to provide vertical clearance between the motor to
the casing adapter and the top of the table surface. Actual clearance dimensions
vary between Whizard tools -see listing of tools as illustrated in Figure 1. (Table
top height may be set differently based on operator height and the height of the
meat product on the table).
The yoke should be rigidly mounted and parallel to the work station.

collar and inserting the adapter end of the casing into the disconnect body.
It may be necessary to rotate the casing assembly to align the square drive of the
flex shaft with the square hole in the motor shaft adapter.
Release the disconnect collar to secure the casing to the motor assembly. The flex
shaft casing assembly should swivel freely.
5.3 Connecting The Power
Connect the motor power cord to the prescribed voltage on the motor nameplate.
The motor must be connected to a ground. Use only approved type connector.
WARNING
ELECTRICAL SHOCK MAY OCCUR!
USE ONLY 3WIRE GROUND TYPE CONNECTOR.
THIS MUST BE CONNECTED TO APLANT GROUND
VIA ASUITABLE GROUNDED THREE CONDUCTOR
RECEPTACLE. AVOID USE OF THIS MACHINE
