SECTION 00 - - GENERAL - - CHAPTER 1 5 SAFETY RULES ensurethatallpressureisrelievedfromhydraulic circuits before removing caps, covers, valves, etc. Generalities Carefully maintenance procedures. follow specified repair and All repair and maintenance operations should be carried out with the greatest care and attention. 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. Never check or fill fueltanks 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. To transfer a failed tractor, use a trailer or a low loading platform trolley if available. To load and unload the machine from the transportationmeans,selectaflatareaproviding afirmsupporttothetrailerortruckwheels.Firmly tie the machine to thetruck ortrailer platformand 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, dieseloilor other flammable liquids as cleaning agents. Use non--flammable non--toxic proprietary solvents. Do unbuttoned or flapping clothing such as ties, torn clothes,scarves,openjacketsorshirtswithopen zipswhichcouldgetcaughtonmovingparts.Use approved safety clothing such as anti--slipping footwear, gloves, safety goggles, helmets, etc. not wear rings, wristwatches, jewels, Wear safety glasses with side guards when cleaning parts using compressed air. 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. 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. All persons 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 seatoratthesideofthemachinewhenoperating the fender switches. Do not pile up grease or oil soaked rags, as they constitute a great fire hazard. Always place them into a metal container. Never carry out any operation on the machine when the engine is running, except when specifically indicated. Stop the engine and

Never bring your head, body, arms, legs, feet, hands, fingers near fans or rotating belts. medicalattention may result in serious infections or dermatitis. Always take system pressure readings using the appropriate gauges. WHEELS AND TYRES Check that the tyres are correctly inflated at the pressure specified Periodically check for possible damage to the rims and tyres. ENGINE Always loosen the radiator cap very slowly before removing it to allow pressure in the systemtodissipate.Coolantshouldbetoppedup only when the engine is stopped. Donotfillupfueltankwhentheengineisrunning. Never adjust the fuel injection pump when the tractor is moving. Never lubricate the tractor when the engine is running. by the manufacturer. 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. ELECTRICAL SYSTEMS If it is necessaryto useauxiliary 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 performing any type of service on the electrical system. 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. the batteries before Never inflate tyres using flammable gases as they may originate explosions and cause injuries to bystanders. 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 YOURHANDSTOCHECKFORLEAKS,butuse a piece of cardboard or a piece of wood for this purpose.If anyfluidisinjectedintotheskin,seek medical aid immediately.
