Periodic replacement of important component parts

To ensure safety in operation, you are strongly requested to inspect and service the machine at regular intervals. For added
safety, ask your KUBOTA dealer to replace the following important component parts.
These parts are prone to degradation in material or subject to wear and tear with time. It is difficult to judge how much they
have been affected at regular inspection. It is therefore necessary to replace them with new ones, whether wear is visible
or not after a specified time of use.
If any of them is found worn even before the specified use, it must be repaired or replaced the same way as other parts.
If any of the hose clamps is found deformed or cracked, the hose clamp must also be replaced.
For the hydraulic hoses other than the ones to be replaced periodically, inspect them for the following points. If found
unusual condition, tighten them up, replace them.
When replacing the hydraulic hoses, change their O rings and sealings with new ones.
For replacement of the important parts, contact your KUBOTA dealer.

At the following periodic inspections, check the fuel hoses and hydraulic hoses as well.
