Periodic Replacement Of Safety Critical Parts - Komatsu PW160-7H Operation & Maintenance Manual

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 materials easily wear or deteriorate. How-
ever, it is difficult to judge the condition of the parts simply by peri-
odic 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 replace-
ment 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.
