Dirty oil and a clogged suction strainermay cause the machine to perform poorly andcontinued use may cause component damage.Extremely dirty conditions may require oil changesto be performed more often. For hydraulic oilspecifications, Refer to Specifications, HydraulicSpecifications.Note: Before replacing the hydraulic oil, the oil maybe tested by an oil distributor for specific levels ofcontamination to verify that changing the oil isnecessary. Replace the oil when it fails the test.Refer to Maintenance Procedure, Test or Replacethe Hydraulic Oil.1 Collect a sample of hydraulic oil and place in aclear container.
