Check the filter service indicator
Check to see that the OEM specified service interval has been reached or that the service indicator shows that the filter is due for servicing.
Turn system off and release pressure
Ensure that the hydraulic system is turned off.
Check that there is no pressure present.
Unscrew and remove the old filter and gasket
Properly dispose of the used filter according to local regulations.
Wipe the filter head with a clean cloth
Inspect the new filter for damage
Check the new filter you will be installing for any shipping and handling damage. Do not install a damaged filter.
Apply a thin film of motor oil to the gasket
Align threads – spin filter until gasket contact
Fit the housing to the filter head as instructed on the housing.
