4. PERIODIC REPLACEMENT OF CRITICAL PARTS
To assure prolonged and safe use of the Machine, be sure to conduct the periodic replacement
of parts listed on the table of critical parts especially related to safety and fire.
Since these parts are prone to degradation of material by aging and abrasion and the extent of
the degradation and deterioration cannot be determined, it is required to replace them even if no
abnormality is found in order to maintain their correct functions all the time.
If any abnormality is found in any of these parts, it is required to replace it even if it is before the
predetermined time for replacement.
As to the hoses, if any sign of degradation such as deformation or cracking of the clamp is
detected, replace the clamp at the same time.
Concurrently, conduct the periodic inspections indicated in the following table of the hydraulic
hoses other than the parts of periodic replacements, and if any abnormality is found, execute
retightening or replacement.
• In parallel to the replacement of hoses, replace the O-rings and gaskets as well.
• Contact us or our sales service agency for the replacement of critical parts.
• At a regular inspection indicated in the following table, conduct the inspection of hydraulic
hoses and fuel hoses.
