Always disconnect the negative lead (--) before the positive lead (+); when re-connecting the battery on completion of
the work, first connect the positive terminal (+) and then the negative (--).
l
Before carrying out any arc welding (permitted only on implements attached to the machine) always disconnect the battery
terminals and unplug all the connectors of the electronic control units and the alternator.
l
When topping up lubricants, always wear suitable protective gloves.
l
Do not wear clothing contaminated by engine or hydraulic oil; prolonged contact with the skin can be harmful and may cause
allergic reactions.
l
Used engine oil and hydraulic oil must be disposed of properly; recover used lubricants and dispose of them in accordance
with the applicable regulations.
l
Before carrying out any work on the hydraulic or pneumatic systems, discharge all residual pressure from the circuits.
l
Before carrying out any work on the hydraulic system or engine, allow the oil and engine coolant to cool down.
l
When removing and refitting certain assemblies, it will be necessary to support the tractor; use stands, jacks or blocks capable
of supporting the weight and arrange them in a triangular pattern to prevent the machine from overturning.
l
To lift heavy components, use a hoist or crane. Check that wire ropes, chains or fibre slings are not worn and that hooks are
not damaged.
l
Always use lifting equipment of suitable capacity for the weight of the components to be removed. Ensure lifting equipment is
attached correctly.
l
When lifting or supporting an assembly or component, manoeuvre the parts slowly and carefully to avoid swinging movements
or collision with other components.
l
Never work on components suspended from a hoist or crane.
l
When removing the retaining bolts of a component that could fall, always leave two opposing bolts in place for safety; before
removing these last two bolts, attach the component to suitable lifting equipment or position support blocks.
l
Any oil or fuel spilled during removal or dismantling operations should be cleaned up as soon as possible to prevent the risk
of slipping and fire.
l
When refitting electrical wiring looms and wires, ensure that they are properly secured with their original retaining straps or
brackets to prevent the possibility of damage caused by vibration.
l
Never insert your fingers or hands to check the alignment between fixing holes in components; always use a suitable dowel
of soft material.
l
When refitting assemblies or components, always use the specified tightening torques; the tightening torques indicated in the
paragraphs regarding assembly/refitting operations have been determined through experimentation and must be scrupulously
adhered to.
l
When refitting parts that are subject to vibration or that rotate at high speed, take particular care when carrying out final instal -
lation checks.
0.1.3 - Safety precautions for removal and refitting operations
When removing or refitting parts, always take the following safety precautions.
precautions for removal operations
l
Unless otherwise indicated, lower the lifting equipment until it the component or assembly rests on the ground.
l
After disconnecting hydraulic and fuel system pipes, always fit plugs to the open ends of the pipes to prevent ingress of dirt.
l
Before removing a cylinder, fully retract the piston and secure it in this position using a retaining strap.
l
Use containers of sufficient capacity when draining oil, coolant or fuel.
l
Before removing a part from the machine, check for alignment markings indicating the correct assembly position. If necessary,
make new markings to ensure correct assembly.
l
When unplugging electrical connectors, always grip the connectors firmly to avoid pulling on the wires.
l
Where necessary, label wires and pipes before removal to avoid confusion when reconnecting.
l
Check the number and thickness of any shims removed and keep them together in a safe place.
l
To lift the tractor or any of its main components, use lifting equipment of suitable capacity.
l
When using eyebolts for lifting components, first check that they are not deformed or damaged; screw them fully home and
then turn the bolt so that the eye is aligned with the lifting hook.
l
Before removing a part, clean the surrounding area and, after removing the part, cover it to protect it from dirt and dust.
