4.2.2 UNHOOKING THE SEED DRILL FROM THE TRACTOR

Unhooking the seed drill from the tractor is a very angerous
operation. Great caution must be used and the whole operation
must be carried out following the instructions.
For a correct unhooking operation of the seed drill it is necessary
to proceed on a horizontal level.
1) Lower the supporting base elements
2) Slowly lower the seed drill until it rests completely on the ground.
3) Disconnect the hydraulic pipes from the tractor distributors and
protect the quick couplings with the caps.
4) Unhook the Cardan shaft from the tractor and put it on the
special hook.
5) Loosen and unhook the third point, following the fi rst and se-
cond.

4.3 ADAPTING THE CARDAN SHAFT

The Cardan shaft, supplied with the machine, is of standard length.
It might, therefore, be necessary to adapt the cardan shaft. Should
this be the case, before proceeding, consult the Manufacturer.
- When the Cardan shaft is with drawn to the end of its stroke,
the two pipes should ovelap by at least 15 cm (A Fig. 10/2).
When it is inserted all the way, the minimum admissible play
is 4 cm (B Fig. 10/2).
- When using the equipment on another tractor, check that
conditions are as stated above and check that the guards
complete ly cover the rotating parts of the Cardan shaft.
ATTENTION
For transportation of the seeder, always follow the Manufac-
turer's instructions.

4.4 ADJUSTING THE HYDRAULIC SYSTEM

System regulation
The hydraulic systems provided come equipped with one-way fl ow
regulators (Fig. 11) which allow for the regulation of the quantity
of oil during opening or closing, depending on how the regulators
have been installed:
Flow from A to B, free;
Flow from B to A, choked (regulated).
To regulate, loosen the lock nut (1, Fig. 11) and turn the knob (2).
Once this adjustment has been made, re-tighten the lock nut.
Make sure that the result of this adjustment does not cause
the rising or descent speed, of the lateral frame and the arms
rows marker, to damage the structure itself.
