Keep the hydraulic system clean. Remember to:
•Thoroughly clean before the filling cap is opened or any connector is loosened.
•Use clean containers when filling the oil.
•Only use clean oil that has been stored in a sealed container.
•Do not reuse drained oil.
•Change the oil and filter according to the intervals specified in “Maintenance schedule” on page 29.
In order for a hydraulic system to function without problem, it must be free from foreign objects. When used, the system produces particles, which can cause both wear and abnormal function. In order to remove these particles, the system contains filters. The filters are sized so as to capture the produced particles, but if contaminants are introduced from outside the system, the filters can quickly become clogged and fail to function as intended. If there are contaminants in the system, further contamination will be produced in a
