Installation Notes

Installation should be performed by a qualified technician. Before servicing, relieve all hydraulic system pressure and allow the system to cool to prevent burns from hot fluid. Apply a light coat of clean hydraulic fluid to the filter gasket before threading on by hand, then tighten according to the filter housing manufacturer's specifications. Dispose of used hydraulic fluid and the old filter in accordance with local environmental regulations.
