General precautions:

• Before performing any greasing or repairs, read all the safety labels stuck to the machine. For the locations of the safety labels and detailed explanation of precautions, see the operation and maintenance manual.• Locate a place in the repair workshop to keep the tools and removed parts. Always keep the tools and parts in their correct places. Always keep the work area clean and make sure that there is no dirt, water or oil on the floor. Smoke only in the areas provided for smoking. Never smoke while working.• When performing any work, always wear the safety shoes and helmet. Do not wear loose work cloths, or clothes with buttons missing. 1. Always wear the protective eyeglasses when hitting parts with a hammer.Always wear the protective eyeglasses when grinding parts with a grinder, etc.• When performing any work with 2 or more workers, always agree on the working procedure before starting. While working, always keep conversations of the work between your fellow workers and your self on any step of the work. During the work, hang the warning tag of “UNDER WORKING” in the operator’s compartment.• Only qualified workers must perform the work and operation which require license or qualification.• Keep the tools in good condition. And learn the correct way to use the tools, and use the proper ones among them. Before starting the work, thoroughly check the tools, lift truck, service vehicle, etc.• If welding repairs is required, always have a trained and experienced welder with good knowledge of welding perform the work.

FOREWORD
GENERAL
This shop manual has been prepared as an aid to improve the quality of repairs by giving the serviceman an
accurate understanding of the product and by showing him the correct way to perform repairs and make judgements.
Make sure you understand the contents of this manual and use it to full effect at every opportunity.
This shop manual mainly contains the necessary technical information for operations performed in a service
workshop. For ease of understanding, the manual is divided into the following chapters; these chapters are further
divided into the each main group of components.
STRUCTURE AND FUNCTION
This section explains the structure and function of each component. It serves not only to give an understanding
of the structure, but also serves as reference material for troubleshooting.
In addition, this section may contain hydraulic circuit diagrams, electric circuit diagrams, and maintenance
standards.
TESTING AND ADJUSTING
This section explains checks to be made before and after performing repairs, as well as adjustments to
be made at completion of the checks and repairs.
Troubleshooting charts correlating “Problems” with “Causes” are also included in this section.
DISASSEMBLY AND ASSEMBLY
This section explains the procedures for removing, installing, disassembling and assembling each component,
as well as precautions for them.
MAINTENANCE STANDARD
This section gives the judgment standards for inspection of disassembled parts.
The contents of this section may be described in STRUCTURE AND FUNCTION.
OTHERS
This section mainly gives hydraulic circuit diagrams and electric circuit diagrams.
In addition, this section may give the specifications of attachments and options together
