Blade Maintenance
Clean (don’t use grease solvent) any resin and plant residue from the
blades before and after using the machine.
With new blades: after the first working hour you need to inspect the
blades and if necessary adjust the gap between them for a correct
play.
Adjustments (Fig.46): loosen nut (1): slightly tighten screw (2), then
unscrew it 1/4 of a turn. Tighten nut (1). Occasionally disassemble and
clean screw and nut (1 and 2).
Sharpening (Fig.47): always keep the file or sharpener at an angle of
45° to the blade, and:
• Always grind in the direction of the cutting edge;
• 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.
WARNING: Do not try to sharpen a damaged blade:
change it or take it to a Service Dealer.
• Check that the blade guard is not damaged or distorted. Replace
the blade guard if it is bent or damaged.
• Never repair damaged cutting attachments by welding,
straightening or modifying the shape.
