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 diffi cult
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 specifi ed time of use.
If any of them is found to be worn before the specifi ed use. They must be repaired or replaced
the same as other parts.
If any of the hose clamps are found deformed or cracked, the hose slamps must also be
replaced.
For the hydraulic hoses other than the ones to be replaced periodically, inspect them for the
following points. If found loose or very worn, tighten and/or replace the hose.
When replacing the hydraulic hoses, change their O rings and sealing components 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.
