4. SAFETY CRITICAL PARTS
For using the machine safely for an extended period of time, you must periodically replace the safety
critical and fire prevention-related parts listed in the table of important parts.
Material quality of these parts can change as time passes and they are likely to wear out or deteriorate.
However, it is difficult to determine the extent of wear or deterioration at the time of periodic maintenance.
Hence, it is required to replace them with new ones regardless of their condition after a certain period of
usage. This is important to ensure that these parts maintain their full performance at all times.
Furthermore, should anything abnormal be found on any of these parts, replace it with a new one even if
the periodic replacement time for the part has not yet arrived.
If any of the hose clamps show deterioration like deformation or cracking, replace the clamps at the same
time as the hoses.
Also perform the following checks with hydraulic hoses which need to be replaced periodically. Tighten a
ll loose clamps and replace defective hoses, as required.
• When replacing hoses, always replace O-ring, gasket, and other required parts at the same time.
• When replacing safety critical parts, contact us or our sales service agency.
