A Foreword – Reading instructions 7 page References between different information types The maintenance manual contains different types of information and is mainly divided in function groups, see section A Foreword . The basic rule of searching for information is to use function groups to find different types of information regarding the function or com- ponent in question. As a complement to this, there are written ref- erences according to the below.
Function descriptions (Section 0-12) Hydraulic diagrams (Section E) Error codes (Section D) Diagnostic test Wiring diagrams (Section 8) (Section E) From Function description to Hydraulic diagram, for hydraulic diagrams of function in question. From Error codes to Diagnostic test, for diagnostic menu to trou- bleshoot component or function in question. From Error codes to Function description, for further informa- tion about components or function. page Product alternatives and optional equipment The information in the manual is divided in modules.
For product al- ternatives and optional equipment, handling of the modules differs depending on if it is the one or the other that is described, see be- low. Special equipment is not described in the manual. When uncertain about the equipment with which the machine is provided, use the machine card to decide which information applies, see Machine card page 8 . Product alternatives Product alternatives are such options that exclude certain standard equipment (e.g., engine alternative). Similar information for different product alternatives are described in separate sections following each other in the same function group.
To show that there are different alternatives, the added text "Product alternative" is used in the heading, together with a simple description of which alternative is described, e.g., "(Product alterna- tive Air conditioning ECC)". Further, alternatives that are optional equipment are marked with the symbol for optional equipment. UDRF01.04GB Maintenance manual DRF 400–450
