2. Switch on the power switch. The red power indicator will be illuminated, and the motor starts.
Note: Do not twist the knife while sharpening. (See: Figure) Each time you insert the blade
simultaneously pull the blade toward you as soon as you feel it coming in contact with the abra-
sive disc. Apply just enough downward pressure to maintain the contact-more pressure will not
modify or speed the sharpening process.
CAUTION: Always ensure that you keep the knife moving along the used slot when it is tangi-
bly in contact with the motor-driven abrasive disc. Otherwise the blade will get jagged. Some
specialized blades are sharpened only at one side of the blade. Select the correct slot for these
knives: in all stages the upwards facing side of the blade will be grinded. Always sharpen the
entire blade length.
3. Slip the knife blade into one slot of the requested stage, ensuring to hold the blade always
horizontal and in parallel with the slot.
To insure even sharpening along the entire blade, insert the blade as close as possible to its
handle.
4. Move the blade gently down until you feel it having
contact with the abrasive disc. At this moment pull the knife
at a steady rate towards you until it exits the slot. Do not
use violence!
For a 20 cm blade (ca. 8 in) each pull should take about
4 seconds. Accordingly, pull shorter blades through in a
shorter time. However, most important for getting a good
result is to pull in a steady way with constant speed.
If the blade is curved, lift the handle slightly as you reach
the curved part of the blade, keeping the part of the blade
edge horizontal (in relation to the table) that is currently in
the middle of the slot
5. As you reach the tip, lift the knife slightly out of the slot.
6. Repeat with the other slot of the selected stage.
In each stage, make an equal number of pulls alternating in
the left and right slots in order to keep the edge facets sym-
metrical.
7. If the edge produced in the currently used stage is
sufficient, on occasion repeat the process in the next stage.
(See: Selecting the Required Stages)
8. If the knife is sufficiently sharp, switch the power switch to the Off position. The red power
indicator light goes out. Unplug the appliance from the power supply.
