CONSUMABLE PARTS
Replace consumable parts such as the filter element or air cleaner element at the time of periodic maintenance
or before they reach the wear limit. The consumable parts should be replaced correctly in order to ensure more
economic use of the machine. When replacing parts, Komatsu recommends using Komatsu genuine parts.
As a result of our continuous efforts to improve product quality, the part number may change. Inform your Ko-
matsu distributor of the machine serial number and check the latest part number when ordering parts.
