TO THE READER:

This workshop manual provides safety information for service activity, general information such as specifications and
dimensions of the machine, mechanisms and structure descriptions of the machine, and service procedures.
Safety
This section contains safety service descriptions and safety label information.
General
This section contains general instructions, tightening torques, general machine information and special tools.
Maintenance
This section contains information for the recommended oil and general maintenance procedures.
Each section basically consists of mechanism and servicing.
Mechanism
Mechanism part contains information and explanations for the structure, functions, and specifications of the machine
or component parts. This part should be comprehended before proceeding with troubleshooting, disassembling,
assembling, and servicing works.
Servicing
Servicing part contains information and procedures for maintenance, troubleshooting and repair works. The reader
should follow these instructions in order to satisfy any servicing work safely, correctly and quickly.
In this WSM, service specifications and service limits are defined as followings.
Service specifications:
Specification which corresponds to new machine’s ex-factory. It is based on quality standard, drawings, or actual
measurements conducted by Kubota. This value is used to determine whether there is a problem with the machine in
the event of a troubleshooting. However, it is necessary to consider degradation due to wear, based on the operating
time of the machine, application or maintenance condition.
Service limits:
Service limit is a value corresponding to the recommended performance limit by taking long term-use wear into
account. When the service limit is reached , the machine is required to have proper repair, overhaul or replacement in
order to keep safe and adequate performance.
All of the illustrations, photographs, specifications, and other information in this manual were created based on the
latest model at the time of publication.
The parts names used in this manual are unified into names representing the functions of the parts. Therefore, it does
not necessarily correspond to the names used in other materials (parts list, operators manual etc.) and the name on
the label/ identification plates on the product.
Kubota reserves the right to change all information at any time without notice.
