ENVIRONMENTAL INFORMATION
Allow the pressure in the hydraulic oil tank to dissipate by opening the hydraulic oil filler neck before unscrewing
the filter casing cover. Otherwise oil is forced out of the filter casing and may enter the environment. Dispose of the
old filter element and escaped hydraulic oil in an environmentally compatible manner.
1. Park the loader on a horizontal surface and apply the parking brake.
2. Lower the lifting frame completely.
3. Switch off the engine.
4. Depressurize the hydraulic system.
5. Unscrew the filter casing cover.
6. Remove the filter element.
7. Fit a new filter element.
8. Check the seal. Replace the seal.
