■ SHARPENING (MA8)
Always keep the file or sharpener at an angle of 45° to
the blade, and:
• Always grind in the direction of the cutting edge;
• Note: files cut only in one direction; lift the file from

the blade when returning to start a new pass; 

• Remove all burr from the edge of the blade with a

slip stone;

• Remove as little material as possible;
• Before refitting the sharpened blades, remove filings

and then apply grease. 

Do not try to sharpen a damaged blade: change it or
take it to a Service dealer.
