3.8.1 ADJUSTING THE HYDRAULIC SYSTEM
The hydraulic systems provided come equipped with one-way fl
ow regulators (1-2, Fig. 62) which allow for the regulation of the
quantity of oil during opening (1) or closing (2), depending on how
the regulators have been installed:
Flow from E to F, free;
Flow from F to E, choked (regulated).
To regulate, loosen the lock nut (3, Fig. 62) and turn the knob (4).
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.
