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.37): 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.38): 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, straigh-
tening or modifying the shape.
