Installation Notes

Oil filter replacement is performed by qualified technicians as part of a standard engine oil service. Always shut down the engine and allow it to cool before removing the filter to prevent burns from hot oil. Use a filter wrench to break loose the old filter and hand-tighten the new unit until the gasket contacts the seating surface, then snug per the equipment manufacturer's specification. Dispose of used oil and filters in accordance with applicable local regulations.
