• 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.
