LFR / en / Edition: 05.2009

Bringing the machine safely into service – The machine must be positioned, moved and operated in such a way that it is stable and that there is no danger of overturning. Only known loads may be moved with the equipment; this applies particularly when using the grab. – Position the upper structure in the longitudinal direction when moving and hold the load as close to the ground as possible. EXCEPTION: “Safe use when loading and unloading (particularly when loading and unloading wood)” on page 8. – Adjust your driving speed to suit local conditions. – Avoid any working movements which may tip the machine. Should the machine start to tip or slide sideways, however, turn the upper structure to face downhill and lower the equipment at the same time. – As far as possible, work downhill or uphill and not side on to the slope. – Drive safely on stony, sleepery or inclined ground – Only drive downhill at the permitted speed or you could lose control of the machine. – Always shift down to a lower running step before a slope. When doing this, the diesel engine must run at maximal speed and the speed may only be reduced using the accelerator pedals. – Load an occupied truck only if all safety requirements are fulfilled, notably in order to protect the truck operator. – For demolition work, digging and crane operations etc., always use protective devices specifically designed for the purpose. – For terrain which is difficult to gain an overview of and whenever necessary, ask for the assistance of a spotter. Only permit one person to give you signals. – Only permit experienced personnel to attach loads and give signals to the machine operator. The spotter must be positioned within the visual range of the operator or be in voice contact with him. – Depending on the equipment combination, there is a risk of collision between the work tool and the cab, the cab protection or the boom cylinders. The greatest degree of care must be taken to avoid damage when the hoe teeth come within this area. – Depending on the equi pment combination, there is a ris k of collision between the lift ring of the attachment and the cab or the cab protection. Before operating, ensure that there is no risk of collision, especially on excavator with cab elevation. If necessary remove the lift ring. – In case of a thunderstorm : • lower the attachment to the ground and if possible anchor the digging tool into the soil. • leave the cab and move away fr om the machine before the storm breaks out. Otherwise, you must stop the excavator, turn off the radio and keep inside the closed cab until the end of the storm. – Auxiliary control units can have various functions. Always check their functions when starting up the machine. – Stop the swinging motion of the uppercarriage when lowering the attachment into a ditch without striking the attachment on the ditch walls. – Inspect the machine for damage if the attachment has been swung into a wall or any other obstacles. – Applications in which the attachment is to be used to strike the material being extracted are not permitted, even when working in a longitudinal direction. – Repeated strikes against an object leads to damage to the steel structures and machine components. – Please refer to your LIEBHERR dealer if special teeth for heavy-duty or special applications are required. – Do not attach too large bucket or bucket with side cutters or that are during operations with rocky material. This would prolong the work cycles and may lead to damage to the bucket as well as further machine components. – With the 2x45° offset articulation, the offset position may only be employed if the working tool or the attachment does not touch the material. – Operation of the offset articulation to drill into the material is not permitted.

Service Manual

Bringing the machine safely into service – Do not lift th e machine during operation. Should this happen, lower the machine slowly back to the ground. – Do not let the machine fall heavily on the ground and do not hold it back with the hydraulics. This would damage the machine. – During operation with the attachment it is fo rbidden to raise the machine with the dozing blade (e.g. carving at the ceiling when tunnelling).

Safe use with a hydraulic hammer – The hydraulic hammer must be selected with particular care. When using a hydraulic hammer not permitted by LIEBHERR, steel structures or the other machine components can become damaged. – Before beginning breaking tasks, position the machine on firm and level ground. – Use a hydraulic hammer designed exclusively for breaking stone, concrete and other breakable materials. – Only operate the hydraulic hammer in the longitudinal direction of the machine and with the windshield closed or with a front protective grid. – Ensure during hammer operation that no cylinder is entirely extended or retracted and that the stick is not in the vertical position. – In order to avoid damages to the machine, try not to break stone or concrete while performing retraction and extension motions of the hydraulic hammer. – Do not apply the hydraulic hammer uninterrupted for more than 15 secs. at a time to th e same place. Change the breaking point. Too long uninterrupted operation of the hydraulic hammer leads to an unnecessary overheating of the hydraulic oil. – Do not use the drop force of the hydraulic hammer to break stone or other materials. Do not move obstacles with the hydraulic hammer. Misuse of this nature would damage both the hammer and the machine. – Do not use the hydraulic hammer to lift objects

– According to use, it can be necessary when working with a grab to move with the equipment raised and the load lifted up; this applies, for example, when loading and unloading wood. – Here, the centre of gravity of the machine will be displaced upwards in the vertical direction. The driving characteristics of the ma chine will thus be influenced pers istently, e.g. through reduction of the dynamic stability. The following instructions are therefore to be observed at all times: • Adjust vehicle ha ndling to suit the a ltered ma chine char acteristics and en vironmental con ditions. • Reduce your speed to prevent the need for sudden braking and steering manoeuvres. • Avoid sudden speed changes, such as braking, accelerating and changing direction. • Only rotate the upper structure when the undercarriage is stationary. • Only rotate the upper structure after you have picked up the load. • Only move the machine when you have picked up and lifted the load and rotated the upper structure to the driving position. • There is a danger of possible swinging movement and dropping of the load when the equipment is raised. • A protective grid (FOPS) in accordance with ISO 10262 must be attached to the cab. • A protective roof (FOPS) in accordance with ISO 10262 must be attached if ther e is a risk of objects falling from above. • Only the maximum permissible load may be taken up using the grab. – NOTE: The weight of a bsorbent materials, such as logs, is de pendent on length, diameter and specific weight. The influencing variables present in a natural product, such as moisture, must be noted.

Safe use when loading and unloading (particularly when loading and unloading wood)

Service Manual

Safety instructions Bringing the machine safely into service

– Working procedures when using machines with grabs re quire t he m achine operator to r eceive special instruction and training. – Use as part of the work process is only permitted when the machine operator has sufficient training and practical experience.

Safe use of machines with tower elevation – Due to the tower elevation, the centre of gravity of the machine will be displaced upwards in the vertical direction. The driving and work characteristics of the machine will thus be influenced persistently, e.g. through reduction of the dynamic stability. – Due to the heightened centre of gravity, the machine must be aligned horizontally before use. In horizontal alignment, the centre of gravity of the upper structure is over the centre of the undercarriage, which reduces the risk of tilting. – The machine can still sway and tilt despite being aligned! The following instructions are therefore to be observed at all times: When moving the machine: • Rotate the upper structure parallel to the undercarriage undercarriage (transport position). • Draw the equipment as close as possible to the machine. • Only at this point may the support feet be retracted and the machine moved. • Moving with loads is not permitted. • Check the terrain to be covered to ensure that the ground is solid and even. Potholes and uneven surfaces jeopardize the stability of the machine. • Adjust vehicle handling to suit the altered machine characteristics (high centre of gravity) and environmental conditions. • Reduce your speed to prevent the need for sudden braking and steering manoeuvres. • Avoid sudden speed changes, such as braking, accelerating and changing direction. • Ascending gradients and obstacles may only be approached in the longitudinal direction in order to prevent unacceptable banking of the machine. • Special care should be taken when driving through narrow passages - drive slowly! When loading and unloading: • The machine must be supported and aligned horizontally before moving (slewing) the upper structure out of the transport position. • It is imperative that you check the contact surface of the support (load carrying capacity of the substrate). A support subsiding would have disastrous consequences! • Carry out all movements with increased care. • To slew the load, move the equipment as close as possible to the machine (Caution! swinging grab)and hold the load close to the undercarriage and above the substrate. • Avoid braking or accelerating the equipment or upper structure abruptly. • Do not lift any loads which are heavier than those given in the load chart.

Protection from vibration – Vibrational loads on mob ile building machinery are mainly the result of the type and method of use. The following parameters in particular are decisive influences: • Terrain conditions: Uneven areas and potholes; • Operational techniques: Speed, steering, brak es, controlling th e machine’s control elements when driving and working. – To a lar ge e xtent, the machine op erator determines the vi brational load s since he sele cts th e speed, gearbox ratio, working method and route himself. This means that there is a wide range of different vibrational loads for the same machine type. Whole-body vibrational load for the machine operator can be reduced if the following recommendations are observed: – Select suitable machines, equipment parts and auxiliary devices for each part of the job. – Use a machine that has a suitable seat (i.e. for earth-moving machinery such as hydraulic excavators, this should be a seat which corresponds with EN ISO 7096).

Service Manual

Bringing the machine safely into service – Keep the seat in good condition and adjust it as follows: • The seat and its damping action should be adjusted depending on the weight and height of the operator. • Check the seat’s damping action and adjustment mechanisms regularly and ensure that these seat characteristics remain as per the seat manufacturer’s instructions. – Check the maintenance status of the machine, particularly with respect to: tyre pressure, brakes, steering, mechanical connections etc. – Do not steer, brake, accelerate, shift gears, move or load the machine’s equipment jerkily. – To reduce vibrational load, adjust the machine speed to suit the route as follows: • Reduce speed when driving on difficult terrain; • Drive around obstacles and avoid driving on very difficult terrain. – Keep the terrain on which the machine is working and driving in good condition: • Remove large stones and obstacles; • Fill in ruts and holes; • Have machines ready to prepare and maintain suitable ground conditions and calculate in sufficient time to carry out any work required. – Drive longer distances (e.g. on public roads) at an appropriate (medium) speed. – Use special auxiliary systems (if available) which reduce vibration for machines that are driven frequently. If such auxiliary systems are not available, regulate speed to avoid "oscillating" the machine.

Towing the machine safely – Always follow the correct procedure: see chapter “Towing the machine” in these operating instructions. – The machine may only be towed in exceptional circumstances, e.g. in order to move the machine away from an area where it is at risk. – Before towing, check all attachments and towing devices for safety and stability. – Towing devices such as bars, cables or ropes must have adequate tensile strength and should be secured around the undercarriage tower or the towing hook provided on the undercarriage. Any damage or accidents which occur while towing the machine are not covered by the manufacturer’s guarantee. – Ensure that there is no one in the vicinity of the towing devices when towing. – Stretch safely and hold the towing devices. Avoid kinks on cables or ropes. – When towing, maintain the correct transport position, permitted speed and route, and avoid lurching. – After towing, return the machine to correct operational status. – When restarting the machine, be sure only to proceed in accordance with the operating instructions.

– Equipment or attachments made by other manufacturers or those which do not have general approval from LIEBHERR for installation or attachment may not be installed or attached to the machine without LIEBHERR’s prior written consent. – LIEBHERR must be provided with the appropriate technical documentation necessary for this purpose. – Before carrying out any major repair work on the equipment, position the machine on level, firm ground. – Do not work beneath the equipment if it is not safely positioned on the ground or supported with wooden blocks. – Before loosening lines or unscrewing bolts, you must store the equipment, switch off the engine and press the start key to the contact position and both joysticks and the pushbuttons to “Turn grab” in order to reduce the pressure in the hydraulic system.

Servicing the machine safely – The crack test should be carried out visually. If a crack is suspected, the dye pe netration test should be carried out as a crack test on areas which do not have good v isibility, such as the rim bearing support, in order to increase testing safety. – Any da mage fo und mu st be r ectified im mediately. We lding wo rk on load -bearing par ts o f the earth-moving machinery, loading devices and transport devices may only be carried out by trained specialist personnel and only in accor dance with the accepted rules of we lding engineering. In case of doubt, contact the LIEBHERR customer support service to discuss suitable remedies.

Welding, drilling, firing and grinding work – Any welding on structural parts (as undercarriage, uppercarriage, equipment parts,…) may only be done the manufacturer, or authorized official dealer. If this ru le is ne glected, the warranty is voided. – Only carry out welding, drilling, firing and grinding work on the machine with express authorization. Clean dust and combustible materials off the machine and its surrounding areas before welding, drilling, firing or grinding. Ensure adequate ventilation. Risk of fire or explosion. – Before welding repairs on other parts, always disconnect the battery. Always remove the negative terminal first and reconnect it last. – Nevertheless if welding repair should be done on components which may contain inflammable gases (welded counterweight, hydraulic tank, fuel tank, …), these components must be previously and sufficiently ventilated with pressurized air to avoid all fire or explosion hazard – Before welding, connect the ground cable as close as possible to the welding point, so the welding current will not run through the swing ring, joints, gears, bushings, rubber parts and seals

Process materials – When working with oils, greases and other chemical substances, observe the appropriate current safety regulations for the product. – Ensure that process materials and replacement parts are disposed of in a safe and environmentally acceptable manner. – Take care when handling hot process materials (Risk of burning and scalding).

– Do not attempt to lift heavy parts. Use devices which are suitable for this purpose and which have sufficient load capacity. When replacing single parts and larger subassemblies, carefully secure them on liftin g devices them so th at they do not present a risk. Only use su itable and correctly functioning lifting devices and load take-up devices with adequate load capacity. Do not stand or work under swinging loads. – Do not use lifting devices which are damaged or do not have sufficient load carrying capacity. Wear work gloves when working with wire cables. – Only permit experienced personnel to a ttach loads and give signals to the cr ane operator. The spotter must be positioned within the visual range of the operator or be in voice contact with him. – When working above body height, use safe climbing devices and working platforms which are appropriate for the job. Do not use machine parts as climbing devices if they are not designed for this purpose. When working at height, wear a harness to prevent falling. Ensure that all grips, steps, rails, platforms and ladders are free of dirt, snow and ice. – Pneumatic cylinders do not have to be used as handles. Open doors and covers carefully, so that pneumatic cylinders do not hit their stops, because this could cause mechanical dammages. – Be sure to support yourself safely when working on the equipment (e.g. replacing teeth).

Servicing the machine safely – New hydraulic accumulators must be charged with the pressure required for the purpose of use before installation. – The operating data (minimum and maximum pressure) are marked permanently on hydraulic accumulators. Ensure that this marking remains visible.

– It is forbidden to carry out repair work on hydraulic hoses and sheathed cables! – All hoses, sheathed cables and bolt connections must be checked re gularly every 2 weeks for externally visible damage and any possible damage must be immediately checked for leakage. – Never check for leaks with your bare hands, use a sheet of paper or something else. – Any damaged parts must be removed immediately! Spurting oil can lead to injury and burns. – Even with correct storage and permitted load, hoses and sheathed cables are subject to the natural aging process. This restricts their duration of use. • Incorrect storage, mechanical damage and unauthorized load are the most common causes of failure. • In relation to duration of use, current norms, regulations and guidelines pertaining to hoses and sheathed cables at place of use must be adhered to. • Use at the limit range of permissible load can shorten duration of use (e.g. high temperatures, frequent movement cycles, extremely high pulse frequencies, multiple shift usage). – Hoses and sheathed cables should be replaced if the following are found during inspection: • Damage to the outer sheath as far as the liner (e.g. chafing, cuts and cracks); • Brittleness of the outer sheath (fracture formation in hose material); • Deformations which do not correspond to the natural form of the hose or sheathed cable, whether in a unpressurized or pressurized state or on bends e.g. sheath separation, blistering; • Unsealed areas; • Non-adherence to requirements during installation; • Damage or deformations to the hose fittings which reduce the tightness of the fittings or the hose / fitting connection; • Hoses working themselves out of the fittings; • Corrosion of the fittings which reduces function and tightness; – When replacing hoses and sheathed cables, use only original replacement parts. – Install and mount hoses and sheathed cables correctly. Do not mix up the connections. – The following is to be noted when replacing hoses and sheathed cables: • Always ensure that the hoses and sheathed cables are installed free of torsion. For high-pressure hoses, the screws from the half-clamps or full flange must always be attached to both hose ends and should only be tightened afterwards. • When tightening the flange on high-pressure hoses and sheathed cables with bent fittings, the side with the bent fitting must always be tightened first and then the side with the straight fitting tightened afterwards. • Any mounting clamps which are located in the centre of the hose may only be attached and tightened subsequently. • Check daily to ensure that all clamps, covers and protective devices are properly fastened. Doing this will prevent vibration and damage during operation. • Install the hoses an d sheathed cables in such a way th at they cannot chafe on oth er hoses, sheathed cables or parts. • A minimum distance from other parts of approx. half the exterior diameter of the hose is recommended. The distance should not, however, be less than 10 to 15 mm. • When replacing the hoses or sheathed cables on moving parts (e.g. from the boom to the stay), check before initial start-up that there are no chafing areas in the entire area of movement.

Lubricants and operating fluids General information on changing lubricants and operating fluids Note The quantities given in the lubrication and operating material chart and on the lubrication chart in the cab are only guide values. X After each oil change or refill, check the level in the relevant unit. Note! Adhering to regulations for lubrication, level checks and operating material changes guarantees a high degree of reliability and a long service life for the machine. It is particularly important to adhere to the oil change intervals and use the specified type of lubricant. X Observe the following when using and checking lubricants and operating fluids: â&#x20AC;&#x201C; see "Lubricants and operating fluids" â&#x20AC;&#x201C; see "Inspection and maintenance schedule" Note! Cleanliness is of the utmost importance when changing oil. X Clean all filler plugs, filler covers and drain plugs and their surroundings before opening. X For preference, drain off oil when it is at operating temperature. X Ensure that old oils are collected and disposed of in an environmentally acceptable manner using the removable oil filter cartridges. Danger! When checking and changing lubrication and operating materials, ensure that the following precautions are adhered to: X Unless otherwise indicated, carry out all work on the machine on level, solid ground and with the engine switched off. X Whenever you reach into the engine compartment, always secure the cover and side doors against accidentally falling back or closing.

LFR / en / Edition: 05.2009

X Only refuel the machine when the engine is switched off, do not smoke and avoid naked flame. X Turn the main battery switch to position 0 (off) and remove the ignition key.

Lubricants and operating fluids specification

2 2.1

Lubricants and operating fluids specification Diesel fuel specification The Diesel fu els mu st meet th e m inimum requirements of the fuel specifications outlined below. Approved fuel specifications. – DIN EN 590 – ASTM D 975 (89a) 1D and 2D The use of fuels with other specifications is only permitted with the explicit consent of the LIEBHERR.

2.1.1

Sulphur content of diesel fuel Fuel that meets the DIN EN 590 standard may contain maximum 50 mg/kg (maximum 0,005 weight percent) of sulphur. The reduction of sulphur content has raised the problem of diesel fue l lubrication characteristics. It has be en sh own tha t d iesel fue ls con taining the m aximum p ermitted Eu ropean s ulphur limit of 0.05 weight per cent can cause the fuel injection system to wear (particularly applicable to distributortype injection pumps). "Low-sulphur" diesel fuels with a sulphur content of less than 0,05% are only suitable after addition of a lubrication additive. According to HFRR (60) test, the lubricity of the diesel fuel may not exceed 460 µm (lubricity-corrected wear scar diameter [1.4] at 60 °C). When using diesel fuels with a sulphur content of more than 0,5 weight percent, the oil change intervals must be halved. Do not use fuels with a sulphur content of more than 1 %. Note! The ASTM D 975 fuel standard does not specify that the fuels must undergo a fuel lubricity test. A written confirmation of compliance from fuel supplier must be submitted. The additives should be added by the supplier, who is responsible for the quality of the fuel. We advise machine operators not to add any secondary lubricity additives to the fuel ASTM D 975 fuels must have a cetane number of minimum 45. A cetane number of more than 50 is preferable, especially at temperatures below 0 °C (32 °F).

2.1.2

Diesel fuels for operation at low temperatures (winter)

Caution! For technical and reasons, it is forbidden to add petroleum fuel to the diesel. For arctic climates, use special diesel fuels developed for such extreme conditions. X In the case of insufficient fluidity of th diesel fuel or températures below -20 °C: use a start-up aid, such as a fuel filter heater.

R 964 C / R 974C

1.55.2 copyright by

At low temperatures, paraffin crystals are formed in the diesel fuel. They increase the flow reduction in the fuel filter, so that the diesel engine might not be supplied with sufficient fuel.

Service Manual

2.2

Diesel fuels with the LIEBHERR Particles filter Caution! If the Liebherr particle filter is installed on the excavator, only use white diesel fuels (EN 590).

2.3

Lubricating oil for the Diesel engine Modern Diesel engines must be lubricated with high-performance oils. They consist of a basic oil with special additives. – The lubricating oil requirements for LIEBHERR Diesel engines are based on the following standards and regulations: Classification

Specification

API classification (American Petrol Institute)

CI-4, CH-4 Caution: observe shorter oil change intervals

ACEA (CCMC) - classification (Association des Constructeurs Européens de l´Automobile) Tab. 1

E4, E6, E7

Lubricating oil for the Diesel engine - specifications Caution ! Particle filter only permitted with oil E6.

2.3.1

Viscosity The choice of the lubricating oil viscosity is done according to the SAE classification (Society of Automotive Engineers). The relevant factor for the right choice of the SAE class is the ambient temperature. The SAE classification does not provide any indication as regards the quality of a lubricating oil. Excessively high viscosity might lead to start-up problems. If the viscosity is too low, the oil's lubrication might not be sufficiently efficient.

2.3.2

Lubricating oil change intervals Change intervals: see chapter "Maintenance and inspection schedule". Subsequent oil changes depend on the climate, sulphur content of the fuel and oil grade. For details, see the table below. If the specified operating hours (h) per year are not reached, the Diesel engine oil and filter must be changed at least once every year. A number of adverse factors (unfavorable operating conditions) affect the length of the change interval. Such adverse factors include: – Frequent cold starts – Sulphur content in fuel greter than 0,5 % – Ambiant temperature below -10° C If such a factory apply, the oil and filter must be changed according to th table below: Oil change interval dependent on oil quality:

Biodegradable hydraulic oils Note! Risk of damage to the hydraulic unit! When mixing ester-based biodegradable hydraulic oils with mineral oils, there is a risk of aggressive chemical reactions, which can damage the hydraulic equipment. X Do not mix biodegradable hydraulic oils from different suppliers, and never mix with mineral oils. The use of a partial flow filters is mandatory. Depending on the temperature range, LIEBHERR recommands its poly-alpaha-olefin (PAO, HEPR) oils that are environmentally-friendly according to CEC-L-33-A-93: Liebherr Hydraulic Plus or Liebherr Hydraulic Plus Arctic If these oils are not available locally, use one of the following oils (before choosing an oil, contact our customer service departement). Fully saturated synthetic ester-based oils, HEES Before using biodegradable hydraulic oil, you must consult LIEBHERR. Do not use vegetable oils, as they do not possess the necessary thermal stability. If you wish to use other products, it is your responsibility to obtain a warranty declaration from the oil supplier.

2.5.5

Monitoring, filter change and oil change Note! Biodegradable hydraulic oils must be checked regularly by means of an oil analysis. – Normal operation after change of oil* an then at least every 500 operating hours – Dust intensive application: after change of oil* an then at least every 250 operating hours For mineral oils, an oil analysis is only required if the oil change interval is to be extended. – Normal operation first time after 1500 operating hours, then every 500 operating hours – Dust intensive application: at least every 250 operating hours LIEBHERR r ecommends conta cting WEAR-CHECK** with th ese ana lysis,and to change the oil when indicated by the test results in the lab report (see also customer service and product information).
