10.4 Maintenance Overview
During normal operating condition, the oil will be maintained at the correct
operating temperature.
In order to get the best value from the hydraulic system (including the
recirculation system) one should change the filter element when it indicates
that it is time. The hydraulic oil should be changed after 2,000 hours or 1 year
of service (whichever comes first) or whenever a fluid sample indicates that it is
contaminated and beyond being fixed by simply operating the filter.
