MAINTENANCE
LUBRICANTS, COOLANT AND FILTERS
When carrying out inspection or maintenance of the hydraulic circuits, always bleed the air to release the inter-
nal pressure.
Inspection or maintenance consists of checking the hydraulic oil level, replacing the filters, and changing the
hydraulic oil.
When removing high-pressure hoses, check that the O-ring is not damaged. If it is damaged, replace it.
