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 replace-
ment of the parts given in the table. 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 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 safety critical parts.
