8.1 FREQUENCY OF CHECKS
The frequencies of maintenance operations are given as a
guideline and may vary depending on the type of service
and use of the machine, environment, temperature, climate
factors, etc.
- BEGINNING OF THE SEASON
Check the machine's general operation; this check should be
performed with the seed drill empty.
Run the turbine for a few minutes to remove any moisture
that may be present in the pneumatic circuit due to conden-
sation.
Check that the plastic parts are in good condition. Any de-
terioration of this material due to natural ageing or other
factors may cause damage to these machine components.
Check that the mechanical components are in good condi-
tion and are not rusted.
Clean the parts that are in contact with seeds or fertilizer, such
as hoppers and dispensers; if necessary, disassemble the com-
ponent.
Check that the signalling lights are working properly.
Check that the hydraulic circuit couplings and lines are not
leaking oil.
For models with a separate hydraulic circuit. Check the oil
filter. If it is saturated, change the oil and the filter (use ATF
DEXRON II oil - fill up to the dipstick level, approximately 45
litres). Check the pump's Valvoline oil level. If necessary, top
up to the level mark (SAE 90).
- PERIODICALLY
Make sure that there is no seed or fertilizer in the hoppers
before cleaning the seed drill with compressed air.
Check the condition of all the nuts and bolts. Especially the
parts that are in contact with the ground. Tighten all screws
and bolts.
Check that there are no traces of material, dust, etc. in the
dispensers or in the pneumatic circuits. The accumulation of
debris can damage the pneumatic system.
- END OF THE SEASON
Clean the machine thoroughly with pressurized air; make
sure that there is no seed or fertilizer in the hoppers and
pipes. Pay particular attention when cleaning parts that are
in contact with chemicals.
Adequately lubricate the machine's moving parts (see sec-
tion 8.4 GREASING AND LUBRICATION).
Paint any metal components that have lost their paint due
to wear and tear.
To properly store the machine, you can cover it with a tar-
paulin and store it in a dry place.
Thoroughly inspect all parts and replace any that are damaged
or worn.
It is recommended to place the machine under cover to protect
it from bad weather.
KEEP THE COULTER UNITS CLEAN; ACCUMULA-
TION OF SOIL, STONES, GRASS, ETC. MAY OB-
STRUCT THE SEEDING LINES.
THESE OPERATIONS MUST BE CARRIED OUT
WITH THE TRACTOR ENGINE COMPLETELY
STOPPED AND THE IGNITION KEY REMOVED
FROM THE IGNITION.
Careful maintenance of the machine ensures good perfor-
mance and long life.
