PERIODIC REPLACEMENT OF DEFINED LIFE PARTS
For using the machine safely for an extended period of time, you must periodically replace the safety and fire
prevention-related parts listed in the table of defined life parts.
Material quality of these parts can change as time passes and they are likely to wear out or deteriorate. Howev-
er, it is difficult to determine the extent of wear or deterioration at the time of periodic maintenance. Hence, it is
required to replace them with new ones regardless of their condition after a certain period of usage. This is im-
portant to ensure that these parts maintain their full performance at all times.
Furthermore, should anything abnormal be found on any of these parts, replace it with a new one even if the
periodic replacement time for the part has not yet arrived.
If any of the hose clamps show deterioration like deformation or cracking, replace the clamps at the same time
as the hoses.
Also perform the following checks with hydraulic hoses which need not to be replaced periodically. Retighten all
loose hoses and replace defective hoses, as required.
When replacing hoses, always replace O-rings, gaskets, and other such parts at the same time.
Have your Komatsu distributor replace the defined life parts.
