4.3 Wear parts
Replace wear parts such as the filter element or air cleaner ele-
ment at the time of periodic maintenance or before they reach
the wear limit. The wear parts should be replaced correctly in
order to ensure more economic use of the machine. When
replacing parts, always use KOMATSU genuine parts.
As a result of our continuous efforts to improve product quality,
the part number may change, so inform your KOMATSU distrib-
utor of the machine serial number and check the latest part num-
ber when ordering parts.
