Sharpening the Knife 

When and How Often to Sharpen the Knife 

 

Symptoms of a dull knife are excess waste on the unsliced portion. 

 

The blade needs to be sharpened periodically to provide consistent slices and maximum food product. 

 

Sharpening the blade lightly every few days is more effective than heavy sharpening at less frequent intervals. 

 

WARNING

: The blade can be sharpened up until the distance between  

the cutting edge of the blade and the inside border of the blade guard ring 

is no more than 6 mm, corresponding to a decrease of about 10 mm of 

the size of the original diameter.  Once this value has been reached, it is 

NECESSARY TO REPLACE THE BLADE. 

 

Sharpening the Knife

 

 

NOTE: Before starting check that the grindstones have been cleaned. 

 

Turn the slicer off and rotate the thickness 

selection knob clockwise until it stops and 

the slicer fence plate covers the knife. 

 

Pull back the carriage all the way to the left. 

 
 
 
 
 
 
 
 

 

Clean and dry both sides of the blade before 

sharpening. Please refer to cleaning 

instructions.  

 

Lift the sharpener cover. 

 
 
 
 

 

Turn the sharpener towards the blade.  The 

sharpener is now in the correct position.  

 

 

 

Plug in and select the start button on the slicer. 

 

Push the sharpening stone button and keep it 

pressed for 10-15 seconds 

 
 
 
 
 
 

 

Press the deburring button for 2-3 seconds 

(more could damage the blade edge). 

 

T

URN SLICER OFF

 before inspecting.
