The hydraulic system of the towed machine consists of two independent hydraulic circuits.
•
Vario drive for the blower function with its own oil reservoir
• Hydraulic block with oil supply from the tractor
Within the hydraulic circuits, the drive components and actuators are connected with each other via
hydraulic lines.
In the operating mode, the hydraulic system of the machine is subject to high pressure. In the
operating mode, the temperature of the oil in the system is approx. 90 °C.
WARNING!
Danger due to high pressure and high temperature in the hydraulic system
Hot fluid escaping under high pressure may cause serious injury
.
u
Depressurize the hydraulic system before carrying out any work.
