Carrying Out KOWA (Komatsu Oil Wear A nalysis) KOWA is a mainte nance service that makes it po ssible to prevent machine fail ures and downt ime. With KO WA, the oil is periodically s ampled and analyzed. This en ables early detection of wear of the machine drive parts a nd other problems. We strongly reco mmend you to use this service. The oil analysis i s carried out at actual cost, so the cost is low, and the results of the analysis are reported together w ith recommendations which will reduce rep air costs and machine downtime.
