00-3 GENERAL SAFETY RULES SAFETY NOTES To ensure that machines entrusted to Authorised Service Centres for repair or overhaul continue to function correctly, it is very important that all repair work is carried out in the prescribed manner. The procedures for checks and repairs indicated in this manual are safe and effective. Some of the operations described require the use of special tools and equipment: these tools have been designed for a specific purpose and may ordered directly from the Manufacturers. DO NOT USE MAKESHIFT TOOLS; not only is there is risk of personal injury, but such tools are rarely suited to the purpose for which they are used. To prevent injury to operators, the symbols and are used in this manual to indicate the safety precautions required. The warnings accompanying these symbols must always be adhered to carefully. In potentially hazardous situations, always give priority to personal safety and take the necessary actions to eliminate the danger. GENERAL SAFETY RULES 1 - Even if you have a thorough knowledge of the machine as regards its components, operation and controls, always take particular care when carrying out the following operations. Remember that the machine you are working on is in need of repair or overhaul and consequently may not always be- have as expected. 2 - Before starting work, clean the machine thoroughly to remove all mud, dust and road dirt. Also clean the cab to remove all traces of oil, snow and ice from the access steps and grab rails. 3 - When climbing up to or down from the cab, always ensure you maintain three points of contact at a time (foot or handholds) in order to keep your balance and prevent accidental falls. 4 - Always take special care when carrying out fault diagnosis operations; these operations often require two persons, who must never stand in front of the wheels when the engine is running. 5 - When carrying out checks and repairs, wear close-fitting clothing, safety goggles and protective gloves that are suitable for the task (cleaning, draining fluids, repairs). When working near moving parts, long hair should be gathered up and secured safely under a cap to prevent the risk of entanglement and sever injury. 6 - Do not allow anyone who is not directly involved in the work to come near the machine; ensure that they remain at a safe distance. 7 - Keep well clear of moving parts; when the engine is running, some moving parts are not easily visible and therefore present a risk of entanglement, even if protected by safety guards. 8 - Ensure that the area is well ventilated before starting the engine in order to avoid the formation of dangerous concentrations of toxic gases; always connect suitable fume extraction equipment to the exhaust pipe.

00-4 9 - Under no circumstances start the engine with the safety guards removed; all repair and adjustment operations must be carried out with the engine stopped. 10 - Do not top up fuel, oil or coolant levels when the engine is running. 11 - Never smoke and ensure there are no naked flames nearby when topping up fuel or oil. Always remove the battery from the machine before recharging. 12 - Before checking or removing the battery, stop the engine and remove the key from the starter switch. 13 - Remove the battery and recharge in a well-ventilated area where the tem- perature exceeds 0°C. 14 - When checking or recharging the battery, do not smoke or allow naked flames in the vicinity as the hydrogen gas given off by the battery is highly explosive. 15 - The liquid (electrolyte) contained in the battery is very harmful if it comes into contact with the skin and the eyes; for this reason, always wear gloves and safety goggles with side shields when checking or topping up the battery. Should any electrolyte accidentally come into contact with your skin, wash the affected parts immediately with copious amounts of water. If electrolyte comes into contact with your clothing, this should be removed as soon as possible. In case of accidental ingestion of electrolyte, drink copious amounts of water, milk or vegetable oil and take antacids such as magnesium, bicarbo- nate, etc.. and seek medical attention immediately. 16 - Before working on the electrical systems, always disconnect the battery terminals. IMPORTANT! Always disconnect the negative terminal (--) first and then the positive terminal (+); when re-connecting the battery on completion of the work, first connect the positive terminal (+) and then the negative (--). 17 - Before carrying out any arc welding, on the tractor, always disconnect the battery terminals and unplug all the connectors of the electronic control units and the alternator. 18 - When topping up lubricants, always wear suitable protective gloves. 19 - Do not wear clothing contaminated by engine or hydraulic oil; prolonged contact with the skin can be harmful and may cause allergic reactions. 20 - Used engine oil and hydraulic oil must be disposed of in a proper manner; recover used lubricants and dispose of them in accordance with the applicable regulations. 21 - Before carrying out any work on the hydraulic or pneumatic systems, dis- charge all residual pressure from the circuits. 22 - Before carrying out any work on the hydraulic system or engine, allow the oil and engine coolant to cool down. GENERAL SAFETY RULES

00-5 23 - When removing and refitting certain assemblies, it will be necessary to support the machine; use stands, jacks or blocks capable of supporting the weight and arrange them in a triangular pattern to prevent the machine from overturning. 24 - To lift heavy components, use a hoist or crane. Check that wire ropes, chains or fibre slings are not worn and that hooks are not damaged. 25 - Always use lifting equipment of suitable capacity for the weight of the components to be removed. Ensure lifting equipment is attached correctly. 26 - When lifting or supporting an assembly or component, manoeuvre the parts slowly and carefully to avoid oscillation or collision with other components. 27 - Never work on components suspended from a hoist or crane. 28 - When removing the retaining bolts of a component that could fall, always leave two opposing bolts in place for safety; these bolts should only be removed when the component has been securely attached to a hoist or when supporting blocks have been put in position. 29 - Any oil or fuel spilled during removal or dismantling operations should be cleaned up as soon as possible to prevent the risk of slipping and fire. 30 - When refitting electrical wiring looms and wires, ensure that they are prop- erly secured with their original retaining straps or brackets to prevent the possibility of damage caused by vibration. 31 - Never insert your fingers or hands to check the alignment between fixing holes in components; always use a suitable dowel of soft material. 32 - When refitting assemblies or components, always use the specified tightening torques; the tightening torques indicated in the paragraphs regarding assembly/refitting operations have been determined through experimentation and must be scrupulously adhered to. 33 - When refitting parts that are subject to vibration or that rotate at high speed, take particular care when carrying final installation checks. GENERAL SAFETY RULES

00-6 SAFETY PRECAUTIONS FOR REMOVAL AND REFITTING OPERATIONS ★ When removing or refitting parts, always take the following safety precautions. 1. PRECAUTIONS FOR REMOVAL OPERATIONS • Unless otherwise indicated, lower the working equipment until it rests on the ground. • After disconnecting hydraulic and fuel system pipes, always fit plugs to the open ends of the pipes to prevent ingress of impurities. • Before removing a cylinder, fully retract the piston and secure it in this position using a retaining strap. • Use containers of sufficient capacity when draining oil, coolant or fuel. • Before removing a part from the machine, check for alignment markings indicating the correct assembly position. If necessary, make new markings to ensure correct assembly. • When unplugging electrical connectors, always grip the connectors firmly to avoid pulling on the wires. • Where necessary, label wires and pipes before removal to avoid confusion when reconnecting. • Check the number and thickness of any shims removed and keep them to- gether in a safe place. • To lift the machine or any of its main components, use lifting equipment of suitable capacity. • When using eyebolts for lifting tractor components, first check that they are not deformed or damaged, screw them fully home and then turn the bolt so that the eye is aligned with the lifting hook. • Before removing a part, clean the surrounding area and, after removing the part, cover it to prevent the ingress of dirt and dust. 2. PRECAUTIONS FOR REFITTING OPERATIONS • Tighten nuts and bolts to the specified tightening torques. • When refitting flexible pipes and wires, take care not to twist or tangle them. • Always fit new seals, O-rings, cotter pins and safety stop rings on reas- sembly; make sure that the ends of the cotter pins are separated and bent back so that the pin cannot be withdrawn from the hole. • Ensure that circlips are correctly installed in their seatings. • Always fit new seals, O-rings, cotter pins and safety stop rings; ensure that cotter pins are bent over so that they cannot work loose. • When applying sealant, first clean the surface removing all traces of oil and grease and check for dirt or indentations, then apply the sealant evenly making sure that it forms a continuous film around any fixing holes. • Clean all parts, removing dirt, oxidisation, carbon deposits, burrs and indentations. SAFETY PRECAUTIONS FOR REMOVAL AND REFITTING OPERATIONS

00-7 • Coat all moving parts with a thin film of engine oil. • When reconnecting electrical connectors, first remove all traces of oil, dust and water from the inside of the connector and then push the two halves to- gether firmly; only apply the force necessary to clip the two halves togeth- er. • Bolt down flanged fittings evenly, tightening the bolts gradually in a cross- wise pattern. 3. PRECAUTIONS TO BE TAKEN ON COMPLETION OF REMOVAL/REFITTING OPERATIONS • If coolant has been drained from the engine, refit the drain plug and add new coolant to the correct level. Start the engine to circulate the coolant and then check the level again and top up. • After removing hydraulic components, top up the hydraulic oil to the specified level. Start the engine to circulate the oil in the hydraulic circuits and then recheck the level and top up as necessary. • After having removed a variable displacement pump, connect the drain pipe and fill the pump casing with oil through the filler hole provided. • Grease stub axle housings, cylinder pivot mountings and drive shafts thoroughly after assembly. SAFETY PRECAUTIONS FOR REMOVAL AND REFITTING OPERATIONS

00-8 LIFTING INSTRUCTIONS Components weighing over 25 kg or of significant size must be supported and removed using suitable lifting equipment with wire rope or polyester slings. In the paragraphs regarding removal and refitting operations, the weight of the component or assembly to be lifted is indicated with the symbol WIRE ROPES - SLINGS • Use wire ropes or polyester slings of suitable capacity for the parts to be lifted, referring to the following tables: NOTE. Lifting capacities are calculated with a safety coefficient. • The lifting hook should be attached to the central part of the rope or sling; if the hook is attached near the ends of the rope/sling, this could cause the load to slip during lifting. • Never lift a heavy load using a single rope; always use two or more symmetrically arranged ropes. Suspension of a load from a single rope could cause the load to start rotating and consequently cause the rope strands to untwist or the load to slip; this could lead to serious injury. • Never lift a heavy load when the two branches of the ropes form a wide angle. The permitted load (kg) decreases in inverse proportion to the angle of suspension; the table below indicates how the permitted load varies according to the angle of suspension for two Ø 10 mm ropes each with a load capacity of 1000 kg.
