4.0 MAINTENANCE
Here follows a list of various maintenance operations to be carried
out periodically. Lowered operating costs and a longer lasting
seeding machine depend, among others, on the methodical and
constant observation of these rules.
CAUTION
- The maintenance periods listed in this booklet are only
indicative and are for on normal conditions on use, therefore
be varied depending the kind of service, the more or less
dusty surroundings, seasonal factors, etc. For more serious
conditions of service, maintenance will logically be done
more often.
- Before injecting grease, the nipples must be cleaned to avoid
mud, dust and foreign bodies from mixing with the grease,
otherwise they will reduce or even annul the effect of the
lubrication.
ATTENTION
- Always keep oils and grease out of reach of children.
- Always read the instructions and precautions shown on the
containers and on the product safety sheets.
- Avoid skin-contact.
- After use wash the equipment thoroughly.
- Dispose of grease and used oils in conformity with the
legislation in force.
ATTENTION
Before performing maintenance on the machinery, be sure
to wear appropriate personal protection equipment (safety
footwear, overalls, gloves and safety glasses).
ATTENTION
All maintenance operations must be carried out with the
equipment resting on the ground and disconnected from the
tractor, with support devices securely in place and the rear
rollers resting on the ground.
4.0.1 WHEN THE MACHINE lS NEW
- Before starting the seeding operation grease all parts indicated
by transfer nr. 9 (‘GREASE’) at page 29 of this lea fl et.
- After the fi rst hours of work check that all the bolts are still tight.
- With a new machine, check the hydraulic hoses and connections
before starting the system, and then after that check their
operating safety condition at least once a year.
3.8 ADJUSTING THE HYDRAULIC SYSTEM
1) At the moment of connecting the hydraulic tubes to the hy-
draulic 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 fi 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 surgi-
cal 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 un-
load the hydraulic pressure carrying all the hydraulic
commandos in all the positions some times after to have
extinguished the motor.
12) Before carrying out checking operations, maintenance or
adjustment on the hydraulic system, the operator must put
on suitable PPEs*.

during all of the machine´s operating phases
13) When the hydraulic tubes are not connected to the tractor,
they must be placed in the adequate holder (
