GENERAL SAFETY RULES 23 - When removing and refitting certain assemblies, it will be necessary to support the machine; use stands, jacks or blocks capable of supporting the weight and arrange them in a triangular pattern to prevent the machine from overturning. 24 - 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. 25 - Always use lifting equipment of suitable capacity for the weight of the com- ponents to be removed. Ensure lifting equipment is attached correctly.
26 - When lifting or supporting an assembly or component, manoeuvre the parts slowly and carefully to avoid oscillation or collision with other com- ponents. 27 - Never work on components suspended from a hoist or crane. 28 - When removing the retaining bolts of a component that could fall, always leave two opposing bolts in place for safety; these bolts should only be re- moved when the component has been securely attached to a hoist or when supporting blocks have been put in position. 29 - 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.
30 - When refitting electrical wiring looms and wires, ensure that they are prop- erly secured with their original retaining straps or brackets to prevent the possibility of damage caused by vibration. 31 - Never insert your fingers or hands to check the alignment between fixing holes in components; always use a suitable dowel of soft material. 32 - When refitting assemblies or components, always use the specified tight- ening torques; the tightening torques indicated in the paragraphs regard- ing assembly/refitting operations have been determined through experimentation and must be scrupulously adhered to.
33 - When refitting parts that are subject to vibration or that rotate at high speed, take particular care when carrying final installation checks. 00-5
