The controller type is identified by a code which is attached to each module. The code, for example, ’DB/DS’ identifies it as the module used on a tractor with a 16x16 transmission controlling those functions highlighted in the table above. All the modules on the tractor are linked by the CAN harness and this also links in the instrument cluster, gear display (16x16 only) and diagnostic connector. Refer to the system diagrams in Section 55, Chapter 1 of this repair manual for full controller details and inter connectivity.

DIAGNOSTIC CONNECTORS (ADDITIONAL “C” PILLAR LOCATION) A single diagnostic port, 2, located behind the trim under the transmission control levers, or on the right hand “C” pillar, 1, to interrogate all of the controllers is incorporated into the wiring harness. With the aid of special service tool 380000843, the port can be used to gain access to the on-board H-menu diagnostics, see Section 55, Chapter 1 of this Repair Manual for full details, to download software or to connect in more specialized diagnostic equipment such as the E.S.T. (Electronic Service Tool).

SECTION 00 -- GENERAL -- CHAPTER 1 SAFETY RULES

5

Disconnect the batteries and label all controls to warn that the tractor is being serviced. Block the machine and all equipment which should be raised.

Do not wear rings, wristwatches, jewels, unbuttoned or flapping clothing such as ties, torn clothes, scarves, open jackets or shirts with open zips which could get caught on moving parts. Use approved safety clothing such as anti--slipping footwear, gloves, safety goggles, helmets, etc.

Never check or fill fuel tanks or batteries, nor use starting liquid if you are smoking or near open flames as such fluids are flammable.

The fuel filling gun should always remain in contact with the filler neck. Maintain this contact until the fuel stops flowing into the tank to avoid possible sparks due to static electricity build--up.

Wear safety glasses with side guards when cleaning parts using compressed air.

To transfer a failed tractor, use a trailer or a low loading platform trolley if available.

Damaged or frayed wires and chains are unreliable. Do not use them for lifting or towing.

Wear suitable protection such as approved eye protection, helmets, special clothing, gloves and footwear whenever welding. All persons standing in the vicinity of the welding process should wear approved eye protection. NEVER LOOK AT THE WELDING ARC IF YOUR EYES ARE NOT SUITABLY PROTECTED.

To load and unload the machine from the transportation means, select a flat area providing a firm support to the trailer or truck wheels. Firmly tie the machine to the truck or trailer platform and block wheels as required by the transporter.

Always use lifting equipment of appropriate capacity to lift or move heavy components.

Chains should always be safely fastened. Ensure that fastening device is strong enough to hold the load foreseen. No persons should stand near the fastening point.

The working area should be always kept CLEAN and DRY. Immediately clean any spillage of water or oil.

Never use gasoline, diesel oil or other flammable liquids as cleaning agents. Use non--flammable non--toxic proprietary solvents.

Do not pile up grease or oil soaked rags, as they constitute a great fire hazard. Always place them into a metal container.

Generalities • Carefully follow specified maintenance procedures. •

repair

and

Never carry out any repair on the machine if someone is sitting on the operator’s seat, except if they are qualified operators assisting in the operation to be carried out. Never operate the machine or use attachments from a place other than sitting at the operator’s seat or at the side of the machine when operating the fender switches. Never carry out any operation on the machine when the engine is running, except when specifically indicated. Stop the engine and ensure that all pressure is relieved from hydraulic circuits before removing caps, covers, valves, etc. All repair and maintenance operations should be carried out with the greatest care and attention.

SECTION 00 -- GENERAL -- CHAPTER 1 YOUR HANDS TO CHECK FOR LEAKS, but use a piece of cardboard or a piece of wood for this purpose. If any fluid is injected into the skin, seek medical aid immediately. Lack of immediate medical attention may result in serious infections or dermatitis.

START UP • Never run the engine in confined spaces which are not equipped with adequate ventilation for exhaust gas extraction. •

Never bring your head, body, arms, legs, feet, hands, fingers near fans or rotating belts.

ENGINE • Always loosen the radiator cap very slowly before removing it to allow pressure in the system to dissipate. Coolant should be topped up only when the engine is stopped. •

Do not fill up fuel tank when the engine is running.

Never adjust the fuel injection pump when the tractor is moving.

WHEELS AND TYRES • Check that the tyres are correctly inflated at the pressure specified by the manufacturer. Periodically check for possible damage to the rims and tyres. •

Stay at the tyre side when inflating.

Check the pressure only when the tractor is unloaded and tyres are cold to avoid wrong readings due to over--pressure.

Never cut, nor weld a rim with the inflated tyre assembled.

To remove the wheels, block both front and rear tractor wheels. Raise the tractor and install safe and stable supports under the tractor in accordance with regulations in force.

Deflate the tyre before removing any object caught into the tyre tread.

Never inflate tyres using flammable gases as they may originate explosions and cause injuries to bystanders.

Never lubricate the tractor when the engine is running.

ELECTRICAL SYSTEMS • If it is necessary to use auxiliary batteries, cables must be connected at both sides as follows: (+) to (+) and (--) to (--). Avoid short--circuiting the terminals. GAS RELEASED FROM BATTERIES IS HIGHLY FLAMMABLE. During charging, leave the battery compartment uncovered to improve ventilation. Avoid sparks or flames near the battery area. Do no smoke. •

Do not charge batteries in confined spaces.

Always disconnect the batteries before performing any type of service on the electrical system.

HYDRAULIC SYSTEMS • Some fluid coming out from a very small port can be almost invisible and be strong enough to penetrate the skin. For this reason, NEVER USE

Always take system pressure readings using the appropriate gauges.

REMOVAL AND INSTALLATION • Lift and handle all heavy components using lifting equipment of adequate capacity. Ensure that parts are supported by appropriate slings and hooks. Use lifting eyes provided to this purpose. Take care of the persons near the loads to be lifted.

COOLING

15

DESCRIPTION OF OPERATION

The forced circulation, closed--circuit engine cooling system is composed of the following components: -- Expansion tank: its location, shape and size may change depending on the engine version. -- Radiator, whose job is to dissipate the heat taken by the coolant from the engine. This component, too, is a feature of the version as regards both positioning and engine. -- Viscostatic fan, with the task of increasing the radiator’s dissipating capacity: this, too, belongs to the specific engine version. -- A lubricating oil cooler: this, too, belongs to the specific engine version. -- A centrifugal coolant pump housed at the front of the crankcase. -- A thermostat governing coolant circulation. -- The circuit may also extend to the compressor if the version includes it.

SECTION 10 -- ENGINE -- CHAPTER 1

LUBRICATION Forced--circulation lubrication is accomplished by the oil pump, housed at the front of the crankcase. The lubricating oil is sent from the oil sump to the crankshaft, camshaft and valve control. Lubrication also includes the cooler, turbo--blower and compressor for the compressed air system if there is one. All these components often change according to use and will therefore be covered under the specific heading.
