22. PERIODIC REPLACEMENT OF CRITICAL PARTS
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 user should also carry out periodic replacement of the
parts given in the table on the next page. These parts are particularly closely connected to safety and fire prevention.
With these parts, the material changes as time passed, or they easily wear or deteriorate.
However, it is difficult to
judge the condition of the parts simply by periodic maintenance, so they should always be replaced after a fixed time
has passed, regardless
of their condition.
This is necessary
to ensure that they always maintain their function
completely.
However, if these parts show any abnormality
before the replacement interval has passed, they should be repaired
or replaced immediately.
If the hose clamps show any deterioration,
such as deformation
or cracking, replace the
clamps at the same time as the hoses.
When replacing the hoses, always replace the o-rings, gaskets, and other such parts at the same time. Ask your
Komatsu distributor to replace the critical parts.
No.
