Technical information
This manual has been produced by a new technical information system. This new system is designed to deliver
technical information electronically through Web delivery (eTim), DVD and in paper manuals. A coding system called
SAP has been developed to link the technical information to other Product Support functions, e.g., Warranty.
Technical information is written to support the maintenance and service of the functions or systems on a customer's
machine. When a customer has a concern on his machine it is usually because a function or system on his machine
is not working at all, is not working efficiently, or is not responding correctly to his commands. When you refer to
the technical information in this manual to resolve that customer's concern, you will find all the information classified
using the SAP coding, according to the functions or systems on that machine. Once you have located the technical
information for that function or system then you will find all the mechanical, electrical or hydraulic devices, compo-
nents, assemblies and sub assemblies for that function or system. You will also find all the types of information that
have been written for that function or system, the technical data (specifications), the functional data (how it works),
the diagnostic data (fault codes and troubleshooting) and the service data (remove, install adjust, etc.).
By integrating SAP coding into technical information, you will be able to search and retrieve just the right piece of
technical information you need to resolve that customer's concern on his machine. This is made possible by attaching
3 categories to each piece of technical information during the authoring process.
The first category is the Location, the second category is the Information Type and the third category is the Product:
• LOCATION - is the component or function on the machine, that the piece of technical information is going to describe
e.g. Fuel tank.
• INFORMATION TYPE - is the piece of technical information that has been written for a particular component or
function on the machine e.g. Capacity would be a type of Technical Data that would describe the amount of fuel
held by the Fuel tank.
• PRODUCT - is the model for which the piece of technical information is written.
Every piece of technical information will have those 3 categories attached to it. You will be able to use any combination
of those categories to find the right piece of technical information you need to resolve that customer's concern on his
machine.
That information could be:
• the description of how to remove the cylinder head
• a table of specifications for a hydraulic pump
• a fault code
• a troubleshooting table
• a special tool

INTRODUCTION
How to use this manual
This manual is divided into Sections. Each Section is then divided into Chapters. Contents pages are included at the
beginning of the manual, then inside every Section and inside every Chapter. An alphabetical Index is included at the
end of a Chapter. Page number references are included for every piece of technical information listed in the Chapter
Contents or Chapter Index.
Each Chapter is divided into four Information types:
• Technical Data (specifications) for all the mechanical, electrical or hydraulic devices, components and, assemblies.
• Functional Data (how it works) for all the mechanical, electrical or hydraulic devices, components and assemblies.
• Diagnostic Data (fault codes, electrical and hydraulic troubleshooting) for all the mechanical, electrical or hydraulic
devices, components and assemblies.
• Service Data (remove disassembly, assemble, install) for all the mechanical, electrical or hydraulic devices, com-
ponents and assemblies.
Sections
Sections are grouped according to the main functions or a systems on the machine. Each Section is identified by a
number 00, 35, 55, etc. The amount of Sections included in the manual will depend on the type and function of the
machine that the manual is written for. Each Section has a Contents page listed in alphabetic/numeric order. This
table illustrates which Sections could be included in a manual for a particular product.
