Oil Filter Replacement Procedure

Unscrew and discard the old oil filter
Clean the filter shell and clear differential pressure through holes
Verify differential pressure transmitter functionality
Fill new filter with oil and lubricate sealing ring
Install filter until contact with gasket, then hand-tighten an additional 1/3 turn
Check for leaks after startup

Note: Filter replacement must be performed when the machine is stopped and pressure released. Caution required for hot oil to prevent burns.
