Safety rules SAFETY REGULATIONS:
TO PREVENT ACCIDENTS:

Most accidents or injuries that occur in workshops are the result of non–observance of simple and fundamental safety regulations. For this reason, IN MOST CASES THESE ACCIDENTS CAN BE AVOIDED: by foreseeing possible causes and consequently acting with the necessary caution and care. Accidents may occur with all types of vehicle, regardless of how well it was designed and built. A careful and judicious service technician is the best guarantee against accidents. Precise observance of the most basic safety rule is normally sufficient to avoid many serious accidents.

GENERAL:
• Carefully follow specified repair and maintenance procedures.
• Do not wear rings, wristwatches, jewellery, unbuttoned or loose articles of clothing such as: ties, torn clothing scarves, open jackets or shirts with open zips that may remain entangled in moving parts. It is advised to wear approved safety clothing, e.g: non–slip footwear, gloves, safety goggles, helmets, etc.
• Do not carry out repair operations with someone sitting in the driver’s seat, unless the person is a trained technician who is assisting with the operation in question.
• Operate the vehicle and use the implements exclusively from the driver’s seat.
• Do not carry out operations on the vehicle with the engine running, unless 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 must be carried out using extreme care and attention.
• Service steps and platforms used in a workshop or in the field should be built in compliance with the safety rules in force.
• Disconnect the batteries and label all controls to indicate that the vehicle is being serviced. Block the machine and all equipment which should be raised.
• Do not check or fill fuel tanks, accumulator batteries, nor use starting liquid when smoking or near naked flames, as these fluids are inflammable.
• Brakes are inoperative if manually released for repair or maintenance purposes. In such cases, the machine should be kept constantly under control using blocks or similar devices.
• The fuel nozzle should always be in contact with the filling aperture. Maintain this position until filling operations are completed in order to avoid possible sparks caused by the accumulation of static electricity.
• Only use specified towing points for towing the tractor, connect parts carefully.Make sure that all pins and/or locks are secured in position before applying traction. Never remain near the towing bars, cables or chains that are operating under load
• Transport vehicles that cannot be driven using a trailer or a low–loading platform trolley, if available.
• When loading or unloading the vehicle from the trailer (or other means of transport), select a flat area capable of sustaining the trailer or truck wheels, firmly secure the tractor to the truck or trailer and lock the wheels in the position.
• Electric heaters, battery–chargers and similar equipment must only be powered by auxiliary power supplies with efficient ground insulation to avoid electrical shock hazards.
• Always use suitable hoisting or lifting devices when raising or moving heavy parts.
• Take extra care if bystanders are present.
• Never pour gasoline or diesel oil into open, wide and low containers.
• Never use gasoline, diesel oil or other inflammable liquids as cleaning agents. Use non-flammable non-toxic proprietary solvents.
• Wear safety goggles with side guards when cleaning parts with compressed air.
• Limit the air pressure to a maximum of 2.1 bar (30.5 psi), according to local regulations.
