3.5 Filling and bleeding
After the first installation and after any maintenance you must fill the system with hydraulic
oil.
This operation is intended to completely remove the air from the system ensuring its proper
operation. The hydraulic system must be filled from its highest point, i.e. at the level of the
control station.
After filling, wait 24 hours and vent again to eliminate any air bubbles in the hydraulic system.
NOTE
To avoid the formation of air bubbles in the oil, you need to slowly fill the tank.
NOTE
The filling and bleeding operations must be carry out by at least two operators.
