IMPORTANT

When mounting the blade, make sure to fasten the
spacer, washer and bolt, then fasten the nut.
■ SHARPENING
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.
