8. INTRODUCTION
Safety rules
IMPORTANT NOTICE
All maintenance and repair operations described in this manual should be carried out exclusively by authorised work-
shops. All instructions should be carefully observed and special equipment where indicated should be used.
Anyone who carries out service operations described without carefully observing these instructions will be directly
responsible for any damage caused.
NOTES FOR EQUIPMENT
Equipment shown in this manual is:
• designed expressly for use on these tractors;
• necessary to make a reliable repair;
• accurately built and strictly tested to offer efficient and long-lasting working life.
NOTICES
The words “front”, “rear”, “right hand”, and “left hand” refer to the different parts as seen from the operator’s seat
oriented to the normal direction of movement of the tractor.
SAFETY RULES
PAY ATTENTION TO THIS SYMBOL
This warning symbol points out important messages involving personal
safety. Carefully read the safety rules contained herein and follow advised
precautions to avoid potential hazards and safeguard your safety.
In this manual you will find this symbol together with the following
key-words:
WARNING -it gives warning about improper repair operations and potential
consequences affecting the service technician’s personal safety.
DANGER - it gives specific warning about potential dangers for personal
safety of the operator or other persons directly or indirectly involved in
the operation.
TO PREVENT ACCIDENTS
Most accidents and personal injuries taking place in workshops are due from non-observance of some essential rules
and safety precautions.
The possibility that an accident might occur with any type of machines should not be disregarded, no matter how well
the machine in question was designed and built.
A wise and careful service technician is the best precautions against accidents.
Careful observance of this basic precaution would be enough to avoid many severe accidents.
SAFETY RULES
Generalities
• Carefully follow specified repair and maintenance procedures.
• 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.
• 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.

9. INTRODUCTION
• 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.
• 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.
• 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 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 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 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 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.
• 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.
