PERIODIC REPLACEMENT OF SAFETY CRITICAL PARTS

PERIODIC REPLACEMENT OF SAFETY 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. 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.
