We often fall victim to the logic that equipment can withstand many hours of operation in the hardest environments without the need for extraordinary maintenance. The reality is that machines cannot survive without dedicated attention to contaminants, which can be introduced through many forms (repairs, humidity, hose failures, attachments, wrong fluids and more). In fact, keeping a machine's hydraulic system clean is not an easy task. It requires trained understanding of contamination, root cause, and utilization of advanced tools to control machine health. Some of the tools currently used on mobile equipment include intelligent filter caddies, by-pass filtration, desiccant breathers, sponge projectiles and on-site contamination testing equipment with the ultimate tool being oil analysis. Each of these tools has a specific function and time depending on application and contamination level. Learn how to recognize levels of contamination, probable causes, leading indicators and recommended procedures.
