1. Knife Sharpener Description
The Edlund Company Inc manufactures the Model 401 knife sharpener. It is approved by the
appropriate certifying organizations. The knife sharpener uses a 3-inch diameter by one-inch wide
grinding wheel to sharpen knives and other utensils. The sharpener consists of a grinding wheel,
which is mounted on an arbor and attached to a drive motor. The motor is mounted to a stainless
steel base using motor mounting plates. The sharpener is enclosed in a stainless steel housing
with a plastic knife guide assembly secured to the base with the snap in guides. The unit is
equipped with a rocker switch to turn the motor on or off and a safety interlock switch which will not
allow the unit to operate if the plastic knife guide is not in place.
2. Knife Sharpener Operation
To operate, plug the power cord into a grounded outlet with the same voltage as listed on the
bottom of the knife sharpener base. Turn the unit on using the rocker switch and then use the
following steps.
1. Sanitize your hands and knife prior to sharpening.
2. Hold knife against the outside edge of the left slot.
Warning! Hold knife firmly so that it will not be pulled away by
the rotation of the grinding wheel.
3. Pull the knife through in a horizontal motion keeping pressure on
the wheel light and even.
4. Hold the knife against the outside edge of the right slot and pull
through in a horizontal motion keeping pressure on the wheel light
and even.
5. Repeat steps 2-4 until the desired edge is achieved.
6. Sanitize knife and hands.
Initial sharpening of knives may require several passes to create
the correct angle of the knife. Subsequent sharpening will only
require a few passes to achieve a sharp, long lasting knife-edge.

4. INSTRUCTIONS FOR REPLACING GRIND WHEEL
The grinding wheel is designed to last up to several years based on normal use (this may vary
depending on use). The grinding wheel is fully worn out and needs replacing when the knife no
longer makes contact with the wheel while positioned against the plastic knife guide. A
replacement wheel and arbor can be ordered from your local Edlund dealer as part number
#A526S. To replace the grinding wheel, first unplug the unit from the power source. Remove the
knife guide. Loosen the setscrew (use a 3/32” Allen wrench) until you are able to slide the wheel
and arbor off of the motor shaft (FIGURE 1). Replace with the new wheel and arbor, the factory
sets the stone and arbor with Shim (S291). This shim should be placed between the motor and
the wheel. The wheel should be placed flush against the shim and the setscrew tightened. Next
remove the shim and the wheel will be set .120 inches away from the motor
FIGURE 1. ATTACHING WHEEL
Replace the knife guide. The grinding wheel should be aligned after installation so that an equal portion of
the wheel is visible in the left and right knife guide slots when the knife guide is in place (FIGURE 2). The
knife sharpener is now ready for use.
