    Avoid to drill or bore pressurised containers, and throw cloths impregnated with inflammable substances into suitable containers. Worn out, damaged or consumable parts must be replaced by IVECO Motors original spares. During workshop activity, always keep the work place clean; timely clear or clean floors from accidental liquid or oil spots.
  • Page 5: General Warnings

    Before washing under pressure mechanical parts, protect electric connectors, and central units, if present. Tightening screws and nuts must always be according to prescriptions; IVECO Motors commercial and assistance network is available to give all clarifications necessary to perform repair interventions not provided in this document.
  • Page 6 Do not use a test lamp in checking circuit continuity, but only use proper control apparatuses. Make sure that the electronic devices wiring harnesses (length, lead type, location, strapping, connection to screening braiding, bonding, etc.) comply with IVECO Motors system and are carefully recovered after repair or maintenance interventions.
  • Page 7 VECTOR ENGINES Bonding and screening Negative leads connected to a system bonded point must be both as short and possible and “star“-connected to each other, trying then to have their centering tidily and properly made (Figure 1, re. M). Further, following warnings are to be compulsorily observed for electronic components: Electronic central units must be connected to system bonding when they are provided with a metallic shell.
  • Page 8 Assemblies shall be modified and equipped with additions - and their accessories shall be fitted - in accordance with the assembling directives issued by IVECO Motors. It is reminded that, especially about the electric system, several electric sockets are provided for as series (or optional) sockets in order to simplify and normalise the electrical intervention that is care of preparation personnel.
