Safety measures concerning the hydraulics
1) At the moment of connecting the hydraulic tubes to the
hydraulic system of the tractor, make sure that the hydraulic
systems of the operating machine and the tractor are not under
pressure.
2) For the operative hydraulic connections between tractor and
operating machine, the sockets and plugs should be marked
with colours to distinguish them, to avoid them being used
wrongly. There would be a danger of accident if the connections
were to be swapped round.
3) The hydraulic system is under high pressure; because of
the accident risk, when searching for leakage points special
auxiliary instruments should be used.
4) Not to never carry out the search losses with the ngers or the
hands. The liquids that exit from the holes can be nearly not
visible.
5) During transport by road the hydraulic connections between
tractor and operating machine should be disconnected and
secured to the support provided.
6) Do not use vegetable oils under any circumstance. These
could cause a risk of damage to the cylinder gaskets.
7) The operating pressures of the hydraulic system should be
between 100 bars and 180 bars.
8) Never exceed the indicated hydraulic system pressure levels.
9) Check that the quick hook-ups are coupled correctly; parts of
the system could get damaged if they are not.
10) Oil escaping at high pressure can cause skin injury with the
risk of serious wounds and infection. Call a doctor immediately
if such an incident occurs. If the oil with surgical means is not
removed quickly, can take place serious allergies and/or infec-
tions. Therefore, the installation of hydraulic components in the
tractor driver's cab is strictly forbidden. All the components of
the system should be positioned carefully to avoid parts being
damage during use of the equipment.
11) In case of participation on the hydraulic system, to unload the
hydraulic pressure carrying all the hydraulic commandos in all
the positions some times after to have extinguished the motor.

USE AND MAINTENANCE
Maintenance in safety
During work and maintenance operations, use suitable per-
sonal protection gear:
1) Do not proceed with maintenance and cleaning if the power
take-off has not been disconnected rst, the engine power off,
the hand brake pulled and the tractor blocked with a wooden
block or stone of the right size under the wheels.
2) Periodically check that the bolts and nuts are tight, and if
necessary tighten them again. For this it would be advisable
to use a torque wrench, respecting the values of 53 Nm for
M10 bolts, resistance class 8.8, and 150 Nm for M14 bolts
resistance class 8.8 (Table 2).
3) During assembling, main-tenance, cleaning, fitting, etc.,
with the machine raised, place adequate supports under the
equipment as a precaution.
4) The spare parts must correspond to the manufacturer's spe-
ci cations. Use only original spares.
