Komatsu oil & wear analysis program
The Komatsu Oil & Wear Analysis (KOWA) program uses independent laboratories across the United States to determine how your machine is performing, based on a small sample of oil or other fluids. KOWA detects fuel dilution and coolant leaks, identifies contaminants, and measures wear-metals. C.N. Wood technicians will help interpret this information. Regular sampling provides indications of increasing contaminants, so you can schedule repairs at the optimum time.
