GENERAL WARNINGS Warnings shown cannot be representative of all danger situations possibly occurring. Therefore, it is suggested to contact immediate superiors where a danger situation occurs which is not described. Use both specific and general—purpose toolings according to the prescriptions contained in respective use and maintenance handbooks. Check use state and suitability of tools not subjected to regular check. The manual handling of loads must be assessed in advance because it also depends, besides weight, on its size and on the path. Handling by mechanical means must be with hoisters proper as for weight as well as for shape and volume. Hoisters, ropes and hooks used must contain clear indications on maximum carrying capacity acceptable. The use of said means is compulsorily permitted to authorised personnel only. Stay duly clear of the load, and, anyhow, never under it. In disassembling operations, always observe provided prescriptions; prevent mechanical parts being taken out from accidentally striking workshop personnel. Workshop jobs performed in pairs must always be performed in maximum safety; avoid operations which could be dangerous for the co—operator because of lack of visibility or of his/her not correct position. Keep personnel not authorised to operations clear of working area. Learn operation and safety knowledge necessary relating to the vehicle prior to each intervention on it. Scrupulously observe all safety warnings on the vehicle. Apply suitable signals for the vehicles being repaired. Once the repair intervention has been completed, before starting up the vehicle, perform all checks indicated on paragraph “Controls care of user” of Use and Maintenance handbook. In lack of visibility in operating from the vehicle, charge a person on the ground with assistance. Do not leave unmanned a vehicle in motion during repair interventions. Keep the vehicle stationary by proper chocks. In the case of an intervention on a vehicle lifted from the ground, check the vehicle to be quite steady on special support stands and, in the case of lifting by means of a lift, check manual/automatic safeties to be activated. When it is necessary to perform an intervention on methane—fed vehicles, observe the indications contained inside the document, as well as all specific safety regulations provided. Only remove radiator cap when the engine is cold by cautiously unscrewing it in order to let system residual pressure out. Inflammable fuel and all inflammable fluids and liquids must be handled with care, according to what contained on harmful materials 12—point cards. Refuelling must be performed outdoors with the engine off, avoiding lit cigarettes, free flames or sparks in order to prevent sudden fires/bursts. Adequately store inflammable, corrosive and polluting fluids and liquids according to what provided by regulations in force. Compulsorily avoid to use food containers to store harmful liquids. 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 original spares. During workshop activity, always keep the work place clean; timely clear or clean floors from accidental liquid or oil spots. Electric sockets and electric equipment necessary to perform repair interventions must meet safety rules. For every intervention on vehicle hydraulic, pneumatic, conditioning and AIR — BAG systems, scrupulously observe indications specified in relating manual sections. !

GENERAL WARNINGS Clean units or assemblies detached from the vehicle and carefully check their integrity before overhaul. Tidy up detached or disassembled parts with their securing elements (screws, nuts, etc.) into special containers. Check for the integrity of the parts which prevent screws from being unscrewed: broken washers, dowels, clips, etc. Self—locking nuts with an insert made of nylon must always be replaced. Avoid contact of rubber parts with diesel oil, petrol or other not compatible substances. 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 commercial and assistance network is available to give all clarifications necessary to perform repair interventions not provided in this document. Before welding: - Disconnect all electronic central units, take power cable off battery positive terminal (connect it to chassis bonding) and detach connectors. - Remove paint by using proper solvents or paint removers and clean relevant surfices with soap and water. - Await about 15 minutes before welding. - Equip with suitable fire resistant protections to protect hoses or other components where fluids or other materials flow which may catch fire easily on welding. Should the vehicle be subjected to temperatures exceeding 80°C (dryer ovens), disassemble drive electronic central units. The disposal of all liquids and fluids must be performed with full observance of specific rules in force. Put on, where required by the intervention, garments and protections provided in accident prevention rules; contact with moving parts can cause serious injuries. Use suitable, preferably tight—fitted garments, and avoid to use jewels, scarves, etc. Do not leave the engine in motion at workshop locations not provided with a pipe to scavenge exhaust gas outside. Avoid to breathe fumes coming from heating or from paint welding because they can cause damages to health; operate outdoors or in suitably ventilated areas. Put on proper inspirator if paint powder is present. Avoid contact with hot water or steam coming from the engine, radiator and pipings because they could cause serious burns. Avoid direct contact with liquids and fluids present in vehicle systems; where an accidental contact has occurred, refer to 12—point cards for provisions to make.

GENERAL WARNINGS ON THE ELECTRIC SYSTEM To start up the engine, do not use fast chargers. Start up must only be performed with either separate batteries or special truck. A wrong polarisation of supply voltage in drive electronic central units (for instance, a wrong polarisation of batteries) can cause them to be destroyed. Disconnect the batteries from the system during their recharging with an external apparatus. On connecting, only screw up connector (temperature sensors, pressure sensors etc.) nuts at prescribed tightening torque. Before disconnecting the junction connector from an electronic central unit, isolate the system. Do not directly supply electronic central units servo components at nominal vehicle voltage. Cables must be arranged such as to result to be parallel to reference plane, i.e. as close as possible to chassis/body structure. Once the intervention on the electric system has been completed, recover connectors and wiring harnesses according to original arrangement. Key memorisation procedures are influenced by electromagnetic jamming (mobile phones, etc.). Therefore, during key memorisation: 1 Pay attention that jamming sources are not present in the cab or near the keys. 2. Keys not insered in the panel must be at least 1 meter away. If an intervention has to be made on the electric/electronic system, disconnect batteries from the system; in this case, always disconnect, as a first one, the chassis bonding cable from batteries negative terminal. Before connecting the batteries to the system, make sure that the system is well isolated. Disconnect the external recharging apparatus from the public utility network before taking apparatus pins off battery terminals. Do not cause sparks to be generated in checking if the circuit is energised. 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 system and are carefully recovered after repair or maintenance interventions. Measurements in drive electronic central units, plugged connections and electric connections to components can only be made on proper testing lines with special plugs and plug bushes. Never use improper means like wires, screwdrivers, clips and the like in order to avoid the danger of causing a short circuit, as well as of damaging plugged connections, which would later cause contact problems. Connectors present must be seen from cable side. Connectors views contained in the manual are representative of cable side. ! NOTE Base — October 2004 Print 603.93.381 VI

Print 603.93.381 Base — October 2004 VII 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. — Electronic central units negative cables must be connected both to a system bonding point such as the dashboard opening bonding (avoiding “serial“ or “chain“ connections), and to battery negative terminal. — Analog bonding (sensors), although not connected to battery negative system/terminal bonding, must have optimal isolation. Consequently, particularly considered must be parasitic resistances in lugs: oxidising, clinching defects, etc. — Screened circuits braiding must only electrically contact the end towards the central unit entered by the signal (Figure 2). — If junction connectors are present, unscreened section d, near them, must be as short as possible (Figure 2). — Cables must be arranged such as to result to be parallel to reference plane, i.e. as close as possible to chassis/body structure. 1.

Base — October 2004 Print 603.93.381 VIII OPTIONAL ELECTRICAL AND MECHANICAL PARTS INSTALLATIONS Accessories mounting, additions and modifications on the vehicle are to be performed complying with IVECO mounting instructions (specific document “Instructions for transformation and preparation” is available at Assistance Network workshops). 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. For any exception to mounting instructions, IVECO’s authorisation is necessary. Lack of observance of above described prescriptions involves guarantee lapse. It is absolutely forbidden to make modifications or connections to electric central units wiring harnesses; in particular, the data interconnection line between central units (CAN line) is to be considered inviolable.
