INTRODUCTION 47524342 29/05/2013 1
INTRODUCTION Foreword - How to use and navigate through this manual 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 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 their machine it is usually because a function or system on their ma- chine is not working at all, is not working efficiently, or is not responding correctly to their 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, you will then 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 - the component or function on the machine, that the piece of technical information is going to describe (e.g., Fuel tank). • INFORMATION TYPE - the piece of technical information that has been written for a particular component or func- tion on the machine (e.g., Capacity would be a type of Technical Data describing the amount of fuel held by the fuel tank). • PRODUCT - the model for which the piece of technical information is written. Every piece of technical information will have those three categories attached to it. You will be able to use any combi- nation of those categories to find the right piece of technical information you need to resolve that customer's concern on their machine. That information could be: • the procedure for how to remove the cylinder head • a table of specifications for a hydraulic pump • a fault code • a troubleshooting table • a special tool 47524342 29/05/2013 4
INTRODUCTION Safety rules Personal safety This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible death or injury.

  • 9. INTRODUCTION Foreword - How to use and navigate through this manual 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 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 their machine it is usually because a function or system on their ma- chine is not working at all, is not working efficiently, or is not responding correctly to their 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, you will then 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 - the component or function on the machine, that the piece of technical information is going to describe (e.g., Fuel tank). • INFORMATION TYPE - the piece of technical information that has been written for a particular component or func- tion on the machine (e.g., Capacity would be a type of Technical Data describing the amount of fuel held by the fuel tank). • PRODUCT - the model for which the piece of technical information is written. Every piece of technical information will have those three categories attached to it. You will be able to use any combi- nation of those categories to find the right piece of technical information you need to resolve that customer's concern on their machine. That information could be: • the procedure for how to remove the cylinder head • a table of specifications for a hydraulic pump • a fault code • a troubleshooting table • a special tool 47524342 29/05/2013 4
  • 10. INTRODUCTION Safety rules Personal safety This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible death or injury. Throughout this manual and on machine decals, you will find the signal words DANGER, WARNING, and CAUTION followed by special instructions. These precautions are intended for the personal safety of you and those working with you. Read and understand all the safety messages in this manual before you operate or service the machine. DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury. The color associated with DANGER is RED. WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury. The color associated with WARNING is ORANGE. CAUTION, used with the safety alert symbol, indicates a hazardous situation which, if not avoided, could result in minor or moderate injury. The color associated with CAUTION is YELLOW. FAILURE TO FOLLOW DANGER, WARNING, AND CAUTION MESSAGES COULD RESULT IN DEATH OR SERIOUS INJURY. Machine safety NOTICE: Notice indicates a situation which, if not avoided, could result in machine or property damage. The color associated with Notice is BLUE. Throughout this manual you will find the signal word Notice followed by special instructions to prevent machine or property damage. The word Notice is used to address practices not related to personal safety. Information NOTE: Note indicates additional information which clarifies steps, procedures, or other information in this manual. Throughout this manual you will find the word Note followed by additional information about a step, procedure, or other information in the manual. The word Note is not intended to address personal safety or property damage. 47524342 29/05/2013 9
