SECTION 2.0 Designated Use
2.1 Warning
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 THIS
SPECIFIC MODEL, AND INCLUDES CHANGES IN
OPERATING PROCEDURES MADE BY THE OWNER
OR ANY OF HIS PERSONNEL.
FOR SAFE AND PROPER OPERATION, READ THE ENTIRE
MANUAL BEFORE USING THIS EQUIPMENT.
2.2 Recommended Operation
The Whizard® Power Knife is a hand-held, motorized circular knife created especially for
slicing thin strips of cooked meat for sandwiches such as Gyros and Kabobs. This meat
comes pre-formed as a "cone", which is normally slow-cooked on a vertical oven or broiler.
SECTION 3.0 Function
3.1 Machine Functions
Cutting is accomplished by means of a circular blade driven by a low-voltage motor inside
the handle of the tool. The bottom inner edge of this blade is ground and honed to razor
sharpness. An adjustable depth gauge determines how deep the blade is allowed to cut into
the meat, and also helps to guard the blade. The bottom of the Headpiece frame forms a
support on which to rest the Power Knife when not in use. This ensures that the sharp blade
edge is safely facing downward, and also allows the hot meat juices to drain from the blade.
SECTION 4.0 Safety Features
The Power Knife incorporates a safety trigger to minimize accidental starting of the tool and
an adjustable depth gauge which helps to guard the blade.

SECTION 6.0 Installation
Please review and read all instructions carefully before attempting to use your Whizard®
Power Knife.
To use the Whizard® Power Knife, first provide a
clear work area. Place the Power Supply in a
clean, dry location near the vertical oven or
broiler. Plug the power cord into an appropriate
wall outlet. (Refer to the data plate on the power
supply cover for voltage information for your
unit). Plug the Motor Unit into the power supply
receptacle, lining up the locator tabs on both the
cord and the receptacle as shown at right. Tighten
the knurled fitting.
COMPANY CONFIDENTIAL

Operating Bettcher Industries, Inc. Whizard® Power Knife Manual
Instructions Rev. January 29, 2016
Page 4
SECTION 6.0 Installation (continued)
A six-foot long extension cable is available (Part Number 109128), which allows the Power
Supply to be located away from the work area. A tool holder (part number 109164) may be
installed on the countertop to provide secure storage for the PowerKnife between uses.
Assemble the Motor Unit into the
back of the Headpiece Assembly,
lining up the four lugs on the Motor
Unit with the four notches in the
Headpiece frame. Turn Motor Unit
clockwise until snug, but do not over
tighten as it may damage the handle.
The finned driver will automatically
align itself with the drive pinion
during assembly. Note that the
motor unit will fit into the Headpiece
only one way.
SECTION 7.0 Instructions For Operation
The Power Knife is easy to use. Slice thickness is carefully and consistently controlled by
the depth gauge. This uniform quality of product has traditionally been possible only from a
highly skilled operator using a straight knife. Uniformly-cooked meat can be served due to
its consistent thickness.
The Power Knife consists of three components:
1. The Headpiece Assembly.
This contains the frame
assembly, blade, blade
housing, drive pinion, pinion
cover, depth gauge, and two
bolts with hand knobs.
There is also an optional
blade cover available. This
Headpiece assembly is
quickly removable, and may
be disassembled without
tools. This assembly is fully
cleanable.

SECTION 7.0 Instructions For Operation (continued)
2. The Motor Unit. This
consists of the motor in a
handle-shaped housing, the
drive adapter with a
replaceable finned driver, the
cap/switch assembly with
power cable, and the switch
lever.
3. The Power Supply. The
Power Supply converts
normal grounded AC line
voltage to low-voltage DC
for the motor.
Each component assembly will be covered fully in the sections which follow.
The Power Knife incorporates a safety trigger to minimize accidental starting. TO START,
hold the tool in your operating hand. Use your other hand to push the end of the lever
forward, and simultaneously squeeze the lever with your operating hand. TO SHUT OFF,
simply release the lever.
The tool may be used in either hand.

Operating Bettcher Industries, Inc. Whizard® Power Knife Manual
Instructions Rev. January 29, 2016
Page 6
SECTION 7.0 Instructions For Operation (continued)
To slice meat, START the Power Knife and hold it against the meat with the handle
horizontal (see illustration). Apply a slight cutting pressure and move the knife up (or down)
the meat, as you prefer. Cutting is always done with the trailing edge of the blade- i.e., if
you use a down-stroke, the top half of the blade is cutting. Conversely, on an up-stroke, the
bottom half of the blade is cutting. (Refer to the illustration) Near the bottom of the cone, it
is necessary to use an up-stroke to trim as close as possible to the cone support plate.
The strips of meat will drop from between the blade and the depth gauge as they are cut.
Note: The Power Knife will not cut properly without its depth gauge in place.

SECTION 8.0 Maintenance
This tool is easily disassembled for cleaning without the use of tools. For best
operation, the Power Knife must be kept clean and sharp.
8.1 Headpiece Assembly
WARNING:
The cutting edge of this blade is VERY SHARP! Handle with care!
Note: The use of cut-resistant gloves is recommended
when handling the blade.
Adjusting the Depth Gauge
This operation is to be performed with the POWER OFF.
The Power Knife is adjustable for
depth of cut by moving the depth
gauge up or down. Two types of
depth gauges are available for the
Power Knife. The regular depth
gauge is shown in the top
illustration. When using the
optional blade cover a short-style
gauge must be used. Both types of
gauges are adjusted the same way.
To adjust, loosen the two knobs
and slide depth gauge UP for
thicker cuts, or DOWN for thinner
cuts. For normal cuts, a setting
where the bottom of the depth
gauge is even with the bottom of
the blade is correct.
Re-tighten the knobs. Do not over-
tighten.

8.1 Headpiece Assembly (continued)
Adjusting the Blade Housing
IMPORTANT: During normal
operation, it may be necessary to
periodically loosen and re-tighten
the knobs ONE AT A TIME with
the tool running to allow the
blade to reposition itself within
its housing.
BE CAREFUL! Keep your
hands away from the moving
blade edge.
If the depth gauge is allowed to
move, it must be readjusted as
described.
Blade Maintenance
A sharpening stone and a Bettcher "steel" are
provided with your Power Knife to help you
maintain a good cutting edge, as a sharp
blade requires less effort to cut and gives
better results. When sharpening or steeling
the blade, move the depth gauge up enough
to expose the blade edge. Re-adjust after
sharpening.
STEELING the blade hones the edge to razor
sharpness. This should be done frequently.
However, when the blade edge becomes
nicked and dull and can no longer be brought
to a sharp condition, it is necessary to
SHARPEN the blade using the stone
provided. Sharpening actually removes some
of the blade material to repair the blade edge.
Clean tool thoroughly after sharpening.

STEELING the Blade
CAUTION:
Sharp Blade Cut Hazard
Hold Power Knife in your operating
hand and START tool.
Holding steeling rod horizontal with
your other hand, lay knife flat on the
steel and move it lightly back and forth
across steel several times. Next place
the end of the steeling rod down
through the notch in the depth gauge
and lightly touch the inside surface of
the blade to `raise' the edge for better
cutting. The notch helps to hold the
steel at the proper angle to the blade
edge to prevent "rounding off" or
rolling the edge.
Clean tool thoroughly after sharpening.

8.1 Headpiece Assembly (continued)
SHARPENING the Blade
CAUTION:
Sharp Blade Cut Hazard
Before sharpening, clean the Power Knife
according to the instructions in Section 9.0.
Reassemble the tool.
Place the sharpening stone on a soft, non-
skid surface such as a folded rag or paper
towel.
Turn power ON.
Carefully lower the blade down against the stone. DO NOT get your fingers near the revolving blade, as it is
extremely sharp. Keep the blade level and parallel with the stone. Hold the blade against the stone while
moving it lightly back and forth. Do this just long enough to make the bottom surface of the blade smooth and
flat.
After sharpening is complete, steel the blade following the instructions. Clean Headpiece thoroughly after
sharpening to remove all abrasive dust, following the instructions given. NOTE: Both serrated-edge blades
and straight- edge blades are sharpened and steeled in the same manner.
Blades may also be returned to Bettcher Industries for sharpening, using the small shipping box included with
your Power Knife. There is a fee for this service.
8.2 Motor Unit
Routine Service There are no adjustments on the Motor
Unit.
The finned driver is removable. The
handle has a slot at one end as shown to
allow access to the setscrew. Loosen the
setscrew and remove the driver. When
replacing the driver, make sure the fins are
seated properly in the metal adapter before
tightening the setscrew. Do not over tighten
the setscrew as it can damage the plastic
driver. A drop of nail polish or threadlocker
may be applied to the threads to prevent
loosening. The setscrew should be checked
periodically, as well as the condition of the
driver.
IMPORTANT: The Motor Unit is not
waterproof. DO NOT IMMERSE IT IN
WATER! Damage to the motor could
result.
