70.3 HYDRAULIC CONTROL AND ADJUSTMENT
CAUTION
In this chapter, unless specically indicated, in order to view the setting pressure values and choose
the appropriate pressure gauge, refer to the hydraulic diagrams (670.1.1 679449 HYDRAULIC DIAGRAM,
5 35))37+ (670.1.2 685268 HYDRAULIC DIAGRAM, 5 39)41
70.3.1 MAIN CIRCUIT PRESSURE SETTING
Setting the main pressure relief valve (14, 070.1.1), (14,, 070.1.2)
- On the distributor, connect a pressure gauge to M (1, 070 11).
- Switch on the access platform.
- Control the lowering of arms 1/2 and maintain the control when
the cylinder reaches the stop.
- Check that the pressure gauge displays the pressure recommended
in the hydraulic diagram.
- As required, adjust the setting of the main relief valve (2, 070 11).
70.3.2 STEERING, BASKET/TURRET ROTATION CIRCUIT PRESSURE SETTING
Setting the pressure relief valve (13, 070.1.1), (13, 070.1.2)
- On the distributor, connect a pressure gauge to M1 (1, 070 12).
- Switch on the access platform.
- Control the steering to one side and maintain the control when
the cylinder reaches the stop.
- Check that the pressure gauge displays the pressure recommended
in the hydraulic diagram.
- As required, adjust the setting of the pressure reducer (2, 070 12)
