a second period of operations and a third drain and refill are needed, installation of new filters is desirable. Filters must

Flushing Grease Systems. For systems using grease, it is normally necessary to disassemble the system
and wash the parts, especially the bearings, in a suitable solvent. The parts are then wiped dry, inspected for wear and
pitting, replaced if needed and repacked with the proper product.
