5.6 Periodic replacement of safety-critical parts
To ensure safety at all times when operating or driving the
machine, the user of the machine must carry out periodic main-
tenance. In addition, to further improve safety, the parts in the list
of safety-critical parts on the next page must also be replaced at
the specified intervals. These parts are particularly important for
safety and fire prevention. Please contact your Komatsu distribu-
tor to have them replaced.
The material quality of these parts can change as time passes,
and they are likely to wear out or deteriorate. However, it is diffi-
cult to determine the extent of wear or deterioration during peri-
odic maintenance. Hence it is required to replace these parts
regardless of their condition after a certain period of usage. This
is important to ensure that these parts maintain their full perfor-
mance at all times.
Furthermore, should anything abnormal be found on any of these
parts, replace it with a new one even if the replacement interval
for the part has not yet expired.
If any of the hose clamps show deterioration like warping or
cracks, replace the clamps with the hoses.
Also perform the following checks on those hydraulic hoses that
do not need to be replaced periodically. Tighten loose clamps and
replace defective hoses as required.
When replacing the hoses, always replace the o-rings, gaskets,
and similar parts at the same time.
Contact your Komatsu distributor for the replacement of safety-
critical parts.
