Maintenance

Replacement of the

hydraulic system parts



Ensure that the tractor and machine hydraulic systems are not
pressurized.



Identify the connectors using the color code to avoid incorrect
connections (inverting the functions could cause accidents).

DANGER

Work on the hydraulic system must only be carried out by a

trained and authorized technician

DANGER

The hydraulic system is pressurized.

Before any intervention on the hydraulic system:



Lock the folding extension and all the hydraulically controlled
accessories in rest position.



Reduce the pressure between the tractor and the machine.



Reduce the pressure between the hydraulic accumulators and
the cylinders, even when the accumulators are located on the
cylinders.

Failure to carry out these actions could result in serious
injury or death.

The accumulators contain pressurized gas even when the

hydraulic pressure has dropped.

The hydraulic circuits may be equipped with blocking components.
Consequently, even if you think that the pressure has dropped, be

careful.
