Use onlysuitable and technically faultless lifting gear and suspensionsystems with adequate lifting capacity. Never work or stand undersuspended loads.The fastening of loads and the supervision of crane operatorsshould be entrusted to experienced persons only. The supervisorgiving the instructions must be within sight or sound of theoperator.Always use specially designed or other safety ladders and workingplatforms for carrying out overhead assembly work. Never usemachine parts as a climbing aid. Wear a safety harness whencarrying out maintenance work at greater heights. Keep allhandles, steps, handrails, platforms, landings and ladders freefrom dirt, snow and ice.Before cleaning the machine with water, steam jet (high-pressurecleaning) or detergents, cover or tape up all openings which - forsafety and functional reasons - must be protected against water,steam or detergent penetration. Special care must be taken withelectric motors and switchgear cabinets.Ensure during cleaning of the machine that the temperaturesensors of the fire-warning and fire-fighting systems do not comeinto contact with hot cleaning agents as this might activate the firefightingsystem.After cleaning, remove all covers and tapes applied for thatpurpose!After cleaning, examine all fuel, lubricant and hydraulic fluid linesfor leaks, loose connections, chafe marks and damage. Anydefects found must be rectified without delay!Always tighten any screwed connections that have been loosenedduring maintenance and repair.Any safety devices removed for set-up, maintenance or repairpurposes must be refitted and checked immediately uponcompletion of the maintenance and repair work.Ensure that all used materials and parts are disposed of safely andwith minimum environmental impact.21.6 Warning of special dangers21.6.1 Electrical energyOnly use original fuses with the specified current rating. Switch offthe machine immediately if trouble occurs in the electrical system.Work on the electrical system or equipment may only be carriedout by a skilled electrician or by specially instructed personnelunder his/her control and supervision and in accordance with theapplicable electrical engineering rules.Disconnect the power supply, where applicable, to machines orparts thereof on which inspection, maintenance or repair work is tobe carried out. Before starting any work, check the de-energizedparts for the presence of power and ground or short-circuit them inaddition to insulating adjacent live parts and elements.The electrical equipment is to be inspected and checked at regularintervals. Defects such as loose connections or scorched cablesmust be rectified immediately.Necessary work on live parts and elements must be carried outonly in the presence of a second person who can cut off the powersupply in case of danger by actuating the emergency shut-off ormain power switch. Secure the working area with a red-and-whitesafety chain and a warning sign. Use insulated tools only.Before starting work on high-voltage assemblies and after cuttingoff the power supply, the feeder cable must be grounded andcomponents such as capacitors, short-circuited with a groundingrod.21.6.2 Gas, dust, steam and smokeCarry out welding, flame-cutting and grinding work on the machine only ifthis has been expressly authorized, as there may be a risk of explosionand fire.Before carrying out welding, flame-cutting and grinding operations, cleanthe machine and its surroundings from dust and other inflammablesubstances and make sure that the premises are adequately ventilated(risk of explosion).Observe any existing national regulations if work is to be carried out innarrow rooms.21.6.3 Hydraulic and pneumatic equipmentWork on hydraulic equipment may be carried out only by persons havingspecial knowledge and experience in hydraulic systems.Check all lines, hoses and screwed connections regularly for leaks andobvious damage. Repair damage immediately. Splashed oil may causeinjury and fire.Depressurize all applicable system sections and pressure pipes(hydraulic system, compressed air system) before carrying out any repairwork.Hydraulic and compressed air lines must be laid and fitted properly.Ensure that no connections are interchanged. The fittings, lengths andquality of the hoses must comply with the technical requirements.21.6.4 NoiseAll sound protecting provisions of the machine must be closed duringoperation.Always wear the prescribed ear protectors.21.6.5 Oil, grease and other chemical substancesWhen handling oil, grease and other chemical substances, observe theproduct-related safety regulations!Be careful when handling hot materials (risk of burning or scalding)!21.7 Mobile machinery and equipment(Machinery and equipment used at various sites)For loading use only lifting gear and tackle of sufficient capacity!Appoint a competent supervisor to assist in the lifting operations.Lift machinery and equipment properly with suitable lifting gear and onlyin accordance with the operating instructions (fixing points for liftingtackle, etc.).Only use suitable means of transport with adequate carrying capacity.!Fasten the loads safely using the suitable fixing points!Before or immediately after completion of the loading operations themachine must be secured by means of recommended/supplied devicesagainst inadvertent shifting. A warning sign must be attached to themachine.Before restarting the machine these devices must be properly removed.Carefully refit and fasten all parts removed for transport purposes beforerestarting the machine.Cut off the external power supply of the machine even if only minorchanges of place are planned. Properly reconnect the machine to thesupply mains before restarting.Proceed in accordance with the operating instructions when restarting themachine.19
