■Sharpening (MA7)

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.
