KOWA (KOMATSU OIL WEAR ANALYSIS) 4
This system requires that oil samples be periodically collected and analysed. This is a preventive maintenance
service, which makes it possible to identify faulty parts or worn machine components timely. Thus, failures are
avoided and dead time is reduced.
Many years of experience and the availability of countless data and information allow Komatsu to accurately
determine the conditions of the machine. This also allows us to locate troubles and suggest the most suitable and
fast repair solutions.
Only actual costs are charged to the customer, who receives a report with the analysis results and indications
about the interventions to be carried out. This low-cost service is very useful and allows customers to save money
and avoid many problems.
