. MAINTENANCE OUTLINES OF SERVICE KOWA ANALYSIS ITEMS Measurement of density of metal wear particles This uses an ICP (Inductively Coupled Plasma) analyzer to measure the density of iron, copper, and other metal wear particles in the oil. Measurement of quantity of particles This uses a PQI (Particle Quantifier Index) measurer to measure the quantity of iron particles of 5 µ m or more, enabling early detection of failures. Others 4 - 6 CARRYING OUT KOWA (Komatsu Oil Wear Analysis) KOWA is a maintenance service that makes it possible to prevent machi ne failures and downt ime. With KO WA, the oil is periodically sample d and analyzed.
This enables early detection of wear of the machine drive parts a nd other problems. We strongly recommend you to use this service. The oil analysis is carri ed out at actual cost, so the cost is low, and the results of the analysi s are reported together with recommendations which will reduce rep air costs and machine downtime. ade of items such as the ratio of water in the oi l, density of the antifr eeze coolant , ratio of amic viscosity, enabling a highly precise diagn osis of the machine's OIL SAMPLING Sampling interval 250 hours: Engine 500 hours: Other com ponents mpling oil is well mixed before sampling. at regular fixed intervals.
