9• ASSEMBLY - DISASSEMBLY - ACCESS TO COMPONENTS
CAUTION! Beware: the turning of one blade causes the
turning of the other.
• The lock washers must comply with standard DIN 128, which applies
to right-hand threaded screws as well as left-hand threaded screws.
We recommend that you use only ETESIA original washers (ref.
71052).
• Each time the blade is dismantled, replace the lock washer situated
underneath the head of the blade screw, as well as the shearing
screws (a picture 18).
• Before re-mounting the blades, check the condition of the couplings,
keys (one key per coupling), shearing screws and retaining washer.
• Before re-mounting the blade coupling, do not forget to grease the
end of the shaft.
• Re-mount the blades positioning them at 90° one to the other (picture
19).
• Tighten the blade screws (50 Nm).
• Tighten the shearing screws (8 Nm).
• So that you do not mix up the blades when re-mounting them, they
are marked as follows. R for the right-hand blade, L for the left-hand
blade. «Left» and «Right» are to be understood with the machine
facing forward.
• Mount the blades with the cutting edge in the direction of the
ejection channel.
9• 4 • 3 REPLACING THE SHEARING SCREWS
• The shearbolts (a picture 18) make the connection between the blade
and the blade coupling. In the event of a violent impact, the instant
shearing of these screws protects the whole transmission system.
• Use only ETESIA original shearbolts.
• Tighten the screws to a torque of 8 Nm.
• If you do not possess the tools or skills necessary, please contact
your dealer.
