SECTION 2.0 Designated Use
2.1 Warning
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.

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 fuse
enclosure 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.
WARNING
SHARP BLADES MAY CAUSE CUT INJURY!
UNPACK THE WHIZARD® POWER KNIFE CAREFULLY.

Operating Bettcher Industries, Inc. Whizard® Power Knife Manual
Instructions October 21, 2020
Page 4
SECTION 6.0 Installation (continued)
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.

Operating Bettcher Industries, Inc. Whizard® Power Knife Manual
Instructions October 21, 2020
Page 5
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 October 21, 2020
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
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.
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.

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.

8.1 Headpiece Assembly (continued)
Steeling the Blade
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.
CAUTION:
Sharp Blade Cut Hazard

8.1 Headpiece Assembly (continued)
Sharpening the Blade
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 and 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.
