replace the parts listed in the following table of important parts.
Serious injury or a fire could result if they deteriorate or are damaged.
Table of Important Parts
Above important parts are vulnerable to aging and wear or deterioration and it is difficult to
determine the degree to which they have deteriorated on the occasion of periodic service.
To maintain their proper function at all times, therefore, replace them with new ones after
using them for a specific period of time even if no abnormality is found with the parts. If you
find abnormalities in these parts before their scheduled replacement time is reached, repair
or replace them immediately. If a hose clamp is deformed or cracked, replace it immediately.
When replacing the important parts, please contact a Takeuchi sales or service outlet .
Also check the hydraulic hoses other than the above important parts. If any abnormality is
