Foreword - How use and navigate through this manual

This manual has been produced a new technical information This new system designed deliver technical information electronically through web delivery and paper A coding system called SAP has been developed link the technical information other Product Support functions, e.g., W arranty .

T

echnical information written support the maintenance and service the functions systems a When a customer has a concern their machine usually because a function system their chine not working not working ficiently , not responding correctly their When you refer the technical information this manual resolve that you will find all the information classified using the SAP coding, according the functions systems that machine. Once you have located the technical information for that function you will then find all the electrical hydraulic and sub assemblies for that function Y will also find all the types information that have been written for that function system: the technical data the functional data (how the diagnostic data (fault codes and and the service data install

integrating SAP coding into technical you will able search and retrieve just the right piece technical information you need resolve that concern his This made possible attaching 3 categories each piece technical information during the authoring process.

The first category the the second category the Information T ype and the third category the Product:

• LOCA TION - the component function the machine, that the piece technical information going describe Fuel

• INFORMA TION TYPE - the piece technical information that has been written for a particular component tion the machine Capacity would a type T echnical Data describing the amount fuel held the fuel

• PRODUCT - the model for which the piece technical information written.

Every piece technical information will have those three categories attached Y will able use any nation those categories find the right piece technical information you need resolve that concern their

That information could be:

• the procedure for how remove the cylinder head

• a table specifications for a hydraulic pump

• a fault code

• a troubleshooting table

• a special tool

Manual content

This manual divided into Sections. Each Section then divided into Chapters. Contents pages are included the beginning the then inside every Section and inside every Chapter alphabetical Index included the end each Chapter Page number references are included for every piece technical information listed the Chapter Contents Chapter

Each Chapter divided into four Information types:

• T echnical Data (specifications) for all the electrical hydraulic assemblies sub -

• Functional Data (how works) for all the mechanical, electrical hydraulic devices, components, assemblies sub -

• Diagnostic Data (fault electrical and hydraulic troubleshooting) for all the electrical hydraulic assemblies sub -

• Service Data (remove install) for all the electrical hydraulic assemblies sub -

Sections
