PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS 4
To ensure safety at all times when operating or driving the machine, the user of the machine must always carry out
periodic maintenance. In addition, to further improve safety, the parts in the safety-critical parts list on the next
page must also be replaced at the specified interval. These parts are particularly closely connected to safety and
fire prevention, so please contact your Komatsu distributor to have them replaced.
Material quality of these parts can change as time passes and they are likely to wear out or deteriorate. However,
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 impor-
tant 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 peri-
odic 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 checks with hydraulic hoses which need to be replaced periodically. Tighten all loose clamps and
replace defective hoses, as required.
When replacing hoses, always replace O-rings, gaskets, and other such parts at the same time.
