IMPORTANT :
ALWAYS REPLACE
SECURING ELEMENTS (LOCK-
NUTS AND BOLTS) WHEN THEY
HAVE BEEN REMOVED 5 TIMES.
CAUTION :
ALWAYS REPLACE
DAMAGED KNIVES, NEVER
STRAIGHTEN A BENT KNIFE.
NEVER REPLACE ONE KNIFE ONLY
PER DISC, ALWAYS REPLACE
BOTH OF THEM TO AVOID CREAT-
ING AN OUT-OF-BALANCE FORCE.
Discs are secured by 4 nipple-screws (B) and 4
conical spring washers (C) on a hub (fig. 1).
Two of these diametrically opposite bolts are also used to secure the conical covers on top of the discs. Tighten
all 4 bolts to a torque of
12 daNm (90 ft.lbs)
.
The discs must have their largest diameters positioned at right angles to each other. This positioning must be
scrupulously respected so as to avoid interference between the knives.
Take extra care when fitting the conical spring washers (C) (fig. 1), which must be positioned with the conical centre
at the top.
Discs supplied through our spare
parts department come with a 1 mm
spacer (part no. 568 071 00) (fig. 2)
attached to them. When installing a
new disc check if the gap between
the blades or their mounting bolts
and the cutterbar protection shields
is at least 1 mm. If this is not the case
fit the 1 mm spacer between the disc
and its mounting hub for increased
clearance (fig. 2).
CAUTION
: BEFORE CARRYING OUT SERVICE OR ADJUSTMENTS TO THIS MACHINE, TURN
OFF THE TRACTOR ENGINE, REMOVE IGNITION KEY AND DISCONNECT THE PTO SHAFT.
