CHECKING BLADES ALIGNMENT

Put the machine into a vertical position
or:
Remove the cutting deck.
WARNING! Always wear strong gloves
when handling the bla des.
WARNING! The blades are connected to
each other, the rotation of each blade engages
the rotation of the other.
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.

ports or the shafts for the blades [see 6.9], re placing if
necessary, and check the condition of the point where
the flanges rest on the cutting deck.
IMPORTANT ­ Always replace damaged blades
and do not at tempt to repair or straighten them. Al­
ways use ma nufacturer's genuine spare parts!
