INSTRUCTIONS
The Graef CC120 is designed to sharpen either Straight edge or Serrated edge
blades:
1. Sharpen Serrated Edge Blades only in Stage 3. Do not sharpen serrated blades in
Stages 1 and 2, as that will unnecessarily remove more metal from the serrations.
See Section titled Procedure for Sharpening Serrated Blades for more details.
2. Straight Edge Blades can be sharpened in all three stages, however, use of Stage
1 may be necessary only if the knife is very dull or if you wish to create an edge
with extra "bite". See following Section for more details.
PROCEDURE FOR SHARPENING STRAIGHT EDGE BLADES
STRAIGHT EDGE BLADES: SHARPENING FIRST TIME
Before you turn on the power, remove the cover positioned over Stage 1 and slip a
knife blade smoothly into the slot between the left angle guide of Stage 1 and the
elastomeric spring. Do not twist the knife. (See Figure 3.) (Retain the Stage 1 cover as
a ready reminder of the sharpening steps.)
Move the blade down in the slot until you feel it contact the diamond disk. Pull it to-
wards you, lifting the handle slightly as you approach the tip. This will give you a feel
for the spring tension. Remove the knife and press the Power Switch. A red "indicator"
on the switch appears when this switch is turned "ON."
Stage 1: (If your knife is already reasonably sharp, skip Stage 1 and go directly to
Stage 2.) If you are sharpening a knife for the first time or if the knife is very dull, start
in Stage 1. Pull the knife once through the left slot of Stage 1 (Figure 3) by slipping the
blade between the left angle guide and the polymeric spring while pulling the blade
toward you and simultaneously moving the blade downward in the slot until it engages
the diamond coated disk. You will hear it make contact with the disk. Insert the blade as
close as possible to its bolster or handle. If the blade is curved, lift the handle slightly as
you sharpen near the tip of the knife, keeping the blade edge approximately parallel to
the table. Sharpen the entire blade length. For an eight (8) inch blade, each pull should
take about 4 seconds. Pull shorter blades through in 2-3 seconds and longer blades in
6 seconds. Next, repeat with one full length pull in the right slot of Stage 1.
Note: Each time you insert the blade you should simultaneously pull the blade toward
you. Never push the blade away from you. Apply just enough downward pressure to
make contact with the wheel - added pressure does not modify or speed the sharpen-
ing process. To ensure even sharpening along the entire blade length, insert the blade
near its bolster or handle and pull it at a steady rate until it exits the slot. In each stage,
make an equal number of pulls alternating in the left and right slots in order to keep the
edge facets symmetrical. Generally in Stage 1 you will find that only one pull in each
(left and right) slot is adequate. Then proceed to Stage 2.
