9.6.3 - CHANGING THE HYDRAULIC OIL FILTER
The hydraulic oil filter should be replaced every 250 working hours or when the
clogging indicator light (A) is displayed.
To replace it, perform the following operations:
• Unscrew the cap (B) using a 32mm spanner.
• Extract the filtering element (C);
• Filters should only be replaced with original filters and before they become completely clogged.
• Always check the O-ring and seals when a component of the hydraulic circuit is dismounted or is
replaced. If broken or damaged, replace them.
• Close the cap again and tighten it with the spanner with a maximum torque of 20 Nm.
