9.1 SERVICE FREQUENCY
Service frequency indicated below is illustrative; it can vary
according to the service type and machine use, the environ-
ment, temperature, weather factors, etc.
- SEASON START
Check the general machine operation by performing a revi-
sion with hopper without seeds.
Verify that the plastic parts are in good condition; the wear
of this material due to natural ageing or due to rodents re-
sults in damage to these elements.
Make sure that the mechanical components are in good con-
ditions and not rusted.
Clean the parts in contact with seeds or fertilizer, such as hop-
pers and dispensers.
Make sure that the signalling lights operate correctly.
Verify that the hydraulic circuit fittings and hoses are free
from oil leakages.
For models with an independent 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
Before washing the seed driller with compressed air, make
sure that there are no seed or fertilizers inside the hoppers
and distributors. After washing, start the turbine for some
minutes for extracting the humidity form the pneumatic cir-
cuit.
Check the conditions of the screws. Specially, those in con-
tact with the ground. Tight all screws and bolts.
Verify that there is not material remainders, dust, etc., inside
the dispenser or the pneumatic circuit. Accumulation of re-
mainders may damage the pneumatic system.
- SEASON END
Dully wash the machine with compressed air; make sure that
no seed, fertilizers or any other product remain inside the
hopper, distributor and hoses. Specially, wash the parts in
contact with chemical products.
Dully lubricate the movable parts of the machine (see sec-
tion 9.4 LUBRICATION AND GREASING POINTS)
Paint the metallic components that due to work wear have
lost the painting.
For correct machine storage, cover it with canvas and stor-
age it in a dry environment.
Thoroughly check all the parts and substitute the damaged or
worn ones.
KEEP THE SOWING EQUIPMENT CLEAN; ACCU-
MULATION OF EARTH, STONES, HERB, ETC.,
MAY CLOG THE SOWING HOSES.
Good machine maintenance ensures good operation and
long-lasting life.
THESE OPERATION MUST BE PERFORMED WITH
THE TRACTOR ENGINE FULLY OFF AND WITH
THE KEY OFF THE IGNITION CONTACT.
