Safety rules
Generalities
Carefully follow specified repair and maintenance procedures.
• Do not wear rings, wrist watches, jewels, unbuttoned or flapping clothing such as ties, torn clothes, scarves, open
jackets or shirts with open zips which could get caught in moving parts. Use approved safety clothing such as
anti-slipping footwear, gloves, safety goggles, helmets, etc.
• 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. All persons standing in vicinity of the welding process should wear approved eye protection. Never look
at the welding arc if your eyes are not suitably protected.
• Never carry out any repair on the machine if someone is sitting on the operator's seat, except 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 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 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 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 of a low loading platform trolley if available.
• 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 the 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 propri-
etary solvents.
• Do not pile up grease or oil soaked rags, as they constitute a great fire hazard. Always place them into a metal
container.
Start up
• Never run the engine in confined spaces which are not equipped with adequate ventilation for exhaust gas extrac-
tion.
• Never bring your 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. Never lubricate the tractor when the engine is
running.
