A radiator for cooling the hydraulic circuit oil and a
biodegradable hydraulic oil can be provided as *op-
tional. In case of its refill or replacement, it is impera-
tive to comply with the technical specifications of the
product already present in the system.
To check these pressures, it is necessary to be
equipped with a manometer. Make sure that the ma-
chine is closed and in the rest position and that no-
body is present in the machine's operating range.
Visually inspect all hoses, fittings and all other com-
ponents of the hydraulic system in order to identify
any possible leaks. Normally, leaks on the pipes can
be eliminated by correctly tightening the fittings. If
leaks in the sealing areas (o-rings, sealing rings,
etc.), the restoration of the seal can only be carried
out by replacing the gasket.
All the operations requiring the interven-
tion on the components of the machine,
shall be carried out by authorized and
trained technical staff.
Non-authorized staff shall not replace any
components. Many components have been
calibrated: a correct calibration of these
parts (only in CMC or in authorized Ser-
vices) is necessary to ensure the safety of
the machine.
