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 parts in the safety-critical parts list on the next
page must also be replaced at the specified interval. These parts are particularly closely connected to safety and
fire prevention, so please contact your Komatsu distributor to have them replaced.
With these parts, the material changes as time passes, or they easily wear out 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.
In addition, carry out the following checks for the hydraulic hoses not listed as periodic replacement parts. If any
abnormality is found, tighten or replace the parts.
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.
