4.0 OPERATIONS FOR PUTTING THE MACHINE
INTO SERVICE
4.1 WHEN THE MACHINE IS NEW
- Assemble onto the equipment any parts that may have been delivered
disassembled for transport purposes (follow the instructions given
in the assembly diagrams attached to these parts).
4.2 CHECKS AND PREVENTATIVE MAINTENANCE
- Check that the safety bolts are present on the pins:
a) 3-point linkage connecting pins;
b) pins for locking the row marker arms for road transport.
- Check that the pipes of the hydraulic system are undamaged.
- Check that all the screws are tight.
- Grease the universal joint spiders.
- Grease the row-marker disc pin.
- Check that all the suction tubes are well connected.
- Check that all the drive shafts are properly engaged.
- Carefully check moving parts, dri-ving parts and seed
distribution.
4.3 ATTACHMENT THE TRACTOR
- Connect the equipment to the third point of the tractor using the
safety devices.
- Connect the cardan shaft.
- Connect the hydraulic pipes to the distributors of the tractor.
- Plug the visual signalling units into the socket of the tractor's
electrical system.
- Remove the safety bolts of the row marker arms and the toolbar,
and operate the hydraulic systems to check they are working
correctly. If necessary, adjust the flow regulators where present.
- Lift the equipment off the ground and remove the support legs.
- When travelling by road, lock the row marker arms and the toolbar
in transport position with the safety bolts.
4.4 PREPARING FOR SEEDING
- From the seed chart, according to the row spacing, obtain the
distance between one seed and the next along the row.
- From the longitudinal sowing distance adjustment table, obtain
the combinations of gears on the gearbox and on the drive
wheel that will produce this distance.
- Insert the right seed discs in the distributors.
- Put a small quantity of seed in the hoppers.
- From the driverís seat of the tractor, raise the seeder;
- Operate the power take-off;
- Using the gear lever, put the tractor engine into neutral;
- Brake the tractor and if necessary, secure it with wooden blocks
sized according to the size of the wheels;
- Manually turn the seeder gear drive wheel in the direction in
which the machine is moving;
- Adjust the selector and control through the grate that the plate is
only holding one seed per hole;
- Adjust the planting depth.
- Check the degree of preparation of the seedbed and adjust the
height of the front clod clearer.
- Move along the seedbed for a few metres with the equipment in
working position, and adjust the third point tie rod to obtain true
perpendicularity between machine and ground.
- Start sowing: after a few metres check whether the distributors
are correctly dropping one seed at a time.
4.5 DISTRIBUTION OF CHEMICAL PRODUCTS
- Hoppers and tanks can be filled by hand or using a lifter with a
capacity of at least 200 kg, which must be regularly approved by
the relative authorities.
- When filling the fertilizer and insecticide hoppers, be careful
that foreign bodies do not enter (string, bag paper, etc.).
- Set the quantity to distribute following the information given in
the table (the values given in the table are a rough guide only).
- Adjust the working depth and the distance of the fertilizer
placement units from the sowing row, carefully following the
specific agronomic instructions of each crop.
4.6 DURING SEEDING
- At the end of each run, while reversing, always keep the power
take-off running at sufficient revs. per minute to ensure that the
seeds remain attached to the distributor plates.
- During seeding check the seed distribution frequently and, if
irregular, adjust the selector.
- If there is a loss or decrease of suction, check that the pipes
are not damaged or clogged; if so, replace or clean them,
checking the aspirator belt also.
CAUTION
- The shape, dimensions and material of the drive shaft elastic
pins have been selected for reasons of safety. The use of
non-original or more resistant pins could cause serious dam-
age to the seeding machine.
- Start the power take-off gradually; sudden movements are
harmful to the aspirator belt.
- Avoid curves with the machine grounded, and do not work in
reverse. Always lift it when changing direction or reversing.
- Do not work with the power take-off synchronized with the
wheels.
- Do not exeed the number of revolutions per minute indicated
on the power take-off.
- Never push the tractor to maximum revs.
- Maintain a seed planting speed that is compatible with the
type and preparation of the soil in order to avoid breakages
or damage.
- Low the seeding machine while the tractor is moving so as
not to clog or damage the coulter parts. For the same reason
it is unadvisable to manoeuvre in reverse with the seeder
lowered.
- When filling the seed, fertilizer and insecticide hoppers,
ensure that no foreign bodies (string, paper, etc.) enter them.
DANGER
The seeding machine can transport chemical substances. Do
not allow children, people, pets to come near the seeding
machine.
WARNING
Do not place any bags of fertilizer or any other object on the
fertilizer distributor container covers to avoid breaking them
or endangering property or persons. Load from the outer sides
of the machine.
It is forbidden to come near the containers of the chemical
substances or to open them when the seeding machine is
operating or about to operate.
