Row Marking Arm Length - Gaspardo PA1 Emploi Et Entretien

SYSTEM REGULATION
The hydraulic system is supplied oil-free.
For this reason, before using the machine, make sure that all the
hydraulic cylinders are engaged slowly in both directions until the
piping and cylinders are fi lled with oil.
When the system is operated for the fi rst time and at the be-
ginning of each season, proceed as follows:
- Keep the row marker closed (Fig. 427) and remove the plug (det.
B) from both hydraulic cylinders.
- Release the safety devices (Fig. 425) and open the row marker
arms manually until they sit on the ground.
- Fit the plugs back on the cylinders (det. B, Fig. 428) and close
the row marker arms by engaging the hydraulic system.
The hydraulic systems provided come equipped with one-way ow
regulators (Fig. 429) 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 (Fig. 429);
- Flow from B to A, choked (regulated) (Fig. 429).
To regulate, loosen the lock nut (1) 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 to damage the structure itself. Never
exceed the maximum admissible pressure for the hydraulic
system.

4.9.1 ROW MARKING ARM LENGTH

See Fig. 424 and observe the following rules for correct row market
arm adjustment:
L = D (N +1)
where:
L= the distance between the outer-most element and the row
marker;
D= the distance between the rows;
N= the number of elements working;
Example: D= 13 cm (inch. 5); N= 23 elements.
L= 13 (23+1) = 156 cm
The row marker arms have a safety bolt (A, Fig. 430) so that the
planter unit structure will not be damaged. If they happen to bump
into an obstacle, this bolt will break and so the row marker arm will
rotate to leave the equipment structure intact. Replace the safety
bolt with the bolt supplied (B, Fig. 430).
