GENERAL INSTRUCTIONS
FOR BLADE OR RAM REPLACEMENT
Daily check the condition and wear of blades and rams and their pins.
If you notice irregular consumptions or breaks, carry out immediately the part replacement.
USE ONLY ORIGINAL SPARE PARTS.
BEFORE CARRYING OUT REPLACEMENT, IT IS NECESSARY TO REMOVE THE MACHINE
FROM THE TRACTOR AND BEND IT FORWARD, MAKING IT LAYING ON COUPLING FOR
MODELS WITHOUT BONNET.
For partial replacement:
Besides the blade or ram pair worn or broken, it is necessary to substitute the blade or ram pair diametrically
opposed for not changing the already existing balancing.
For total replacement:
Small differences in weight of parts are unavoidable.
Weigh the single blade or ram blocks, chosing pairs of the same weight.
These pairs should be assembled on the rotor in diametrically opposed positions.
CHANGE THE SELFLOCKING NUTS EVERY TIME
Tighten the M16 nuts with a torque wrench of 100 Nm.
Tighten the M20 nuts with a torque wrench of 250 Nm.
After the adjustment check that there is a small end play (1-2 mm) between blades or rams and their supports.
After the repair,
for checking the balancing
, connect the tractor.
Keeping the machine raised from the ground, slowly increase the P.T.O. speed until reaching the R.P.M.
If the repair has been carried out correctly the machine should rotate at a R.P.M. without strong vibrations.
If the machine assembles the Y blades with
ventilation blades, it is necessary to include also
them in the weighing.
If ventilation blades are used, check the right
direction of assembly.
