If you wish to increase the number of revolutions of the fan for
distributing heavier seeds, carefully proceed as follows (Fig. 31):
a) loosen the handwheel (1 Fig. 31);
b) rotate the handwheel (2 Fig. 31) clockwise or anticlockwise
to reduce or increase pressure and adjust the number of
revolutions of the blower accordingly.
It is prohibited to touch the grain (3) since the hydraulic system
could work to high speed; this can cause the breach of the
motor, the pump or the fan.
Remember furthermore that at the successive start-up of the
system, with cold oil and the position of the regulator untouched,
there will be an initial increase in the blower speed which, once
the right working temperature has been reached, will return to
that set.
4.4 OIL COOLING
When using a dependent system it is important to check the
capacity of the tractor's oil tank and whether the cooling system
is sufficient. If necessary have an oil cooler or a larger tank
installed on the tractor by the dealer: the ratio between the volu-
me of oil in the system and the capacity of the tank should be
approximately 1:2. With the independent system, check the oil
level in the tank daily during the period of use; top up if necessary.
Oil tank capacity (AGIP OSO 32, ISO-L-HM classification) 55 litres.
- Always keep oils and grease out of reach of children.
- Always read warnings and precautions indicated on the
containers carefully.
- Avoid skin-contact.
- After use wash the equipment thoroughly.
- Treat the used oils and polluting liquids in conformity with the
laws in force.
The Manufacturer declines all responsibility due to negligence
and non-observance of these rules.

4.5 HYDRAULIC SYSTEM
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 fingers
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 infections. 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.
