CHECKING
BLADES ALIGNMENT
General informations:
Excessive vibration when cutting and an uneven cut
can be due to misalignment of the blades owing to
deformation of the flanges or the shafts as a result
of accidental knocks.

• Put the machine into a vertical position
Always wear strong gloves when handling the
blades.
To check the alignment of the blades, one of them
must first be removed and refitted after having remo-
ved the shaft key (2), to permit independent blade
rotation.
NOTE
Take note of the unscrewing and screwing direction
of the central screw of each blade (1).
With the blades disengaged, firmly hold each blade
and bring the cutting edges together in the various
positions possible (A-B; A-B1; A1-B1; A1-B); at each
position they should be aligned to within 2 mm.
If higher amounts are found, check that the blades
are not distorted. If this is not the case, check the sup-
ports or the shafts for the blades [see 6.9], replacing
if necessary, and check the condition of the point
where the flanges rest on the cutting deck.
