necessary, follow the procedure outlined on Page 5-6. Remem ber to unplug the electrical supply cord.

(4) Loosen sharpener lock pin (Figure 3 [4]) which bears against sharpener post, then lift sharpener assembly

(Figure 1 [6]) and rotate it 1/2 turn (180 degrees). Then seat it down over knife.

(5) Tighten sharpener lock pin (Figure 3 [4]). As the lock is tightened, it bears on the sharpener post and

automatically aligns the grinding and debumng stones to the precise orientations which are preset at our factory.

(6) Turn slicer ON. Depress the sharpener button and hold in which will start the grinding wheel rotating. Run

until the beveled cutting surface cleans up. This can take from 30 seconds to several minutes depending on how dull the blade was allowed to become. Release sharpener button.

(7) Turn slicer OFF and check for the formation of a very slight burr on the side of knife opposite the bevel

which indicates complete grinding of the bevel. This slight burr can be detected either visually of by picking with a small piece of stiff paper.

(8) Turn slicer ON. Lightly press deburring (honing) button and hold for 1 to 2 seconds while you turn OFF the

slicer. Blade should now be completely sharpened and honed.

CAUTION: It is very important for best slicing results not to deburr the knife too lone or the keen edge will be destroyed due to the formation of an undesirable second bevel on the opposite side. This condition tends to be the primary cause of unsatisfactory slicing results.

(9) Turn slicer OFF. Loosen lock pin, ( Figure 3 [4]) then lift and return sharpener to its storage position. Tighten

lock pin.

(10) Clean slicer and knife according to the cleaning procedure on Page 5-6 in order to thoroughly remove

grinding debris.
