Section 10 - Maintenance
Hydraulic Oil Inspection
Replacement or testing of the hydraulic oil is essential for good machine performance and service life.
Dirty oil may cause the machine to perform poorly and continued use may cause component damage.
Extremely dirty conditions may require oil changes to be performed more often.
Before replacing the hydraulic oil, the oil may be tested by an oil distributor for specific levels of
contamination to verify that changing the oil is necessary.
Hydraulic oil should be tested yearly and replaced if it fails. If the hydraulic oil is not replaced at the
Annual Inspection, test the oil quarterly. Replace the oil when it fails the test.
Note: Perform this procedure with the platform in the stowed position.
1. Slide out the Component Tray.
