Replacing the oil and filters of the hydraulic tank

Changing the hydraulic oil and filter will introduce air in the hydraulic/hydrostatic system and thus it
requires an hydrostatic startup after the replacement. Refer to the training manual to perform an hy-
draulic/hydrostatic oil change, an oil filter change or an hydrostatic startup.
