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

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 .
