1.10: Safety instructions

Working with the machine holds dangers to which you as the owner, machine operator or mainte-nance expert could be exposed. If you regularly read and note the safety information, however, youcan prevent danger and accidents. This is particularly true for those who are only occasionally in con-tact with the machine, eg. for maintenance work. The following information comprises safety regula-tions which, if followed conscientiously, will guarantee your safety and that of other persons, as wellas avoiding damage to the machine.

Following these precautions does not release you from the responsibility to take note of safety regu-lations which apply on site or of guidelines given by legal bodies or professional associations.

For EU countries, guideline 89 / 655 / EEC contains the minimum safety information applicable to theowner.

1 Use in accordance with the regulations� The hydraulic excavator is a machine with work equipment (eg. hoe type bucket, grab, bucket at-

tachment) designed to detach, lift, transport and shake off earth, stones and other materials, whilethe transportation of the load itself usually takes place without moving the machine. Moving themachine when it is carrying a load must be carried out while observing the appropriate safetymeasures (see section "Notes for safe working").

� Machines used for hoisting are subject to specific conditions and must be fitted with the stipulatedsafety devices (see section �Hoisting work�).

� Other or additional usage, eg. for demolition work or transfer work, requires special equipmentand may also require special safety devices. These devices (eg. tree grab, demolition hammer,concrete cutter etc.) may only be attached and used with approval and in accordance with the orig-inal manufacturer of the device.

� Transporting persons is not deemed to be in accordance with regulations. The manufacturer is notliable for damage resulting from this action. The user is solely responsible for the risk incurred.

� Observing the operating instructions and the inspection / maintenance instructions is also deemedto be appropriate use in accordance with regulations.

2 Safety Instructions

General safety instructions� Please familiarize yourself with the operating instructions before starting up the machine. � Ensure that you have obtained, read and understood any additional instructions relating to special

accessories for the machine. � Only specifically authorized persons may operate, maintain or repair the machine. The legal min-

imum age is to be adhered to. � Only employ trained or appropriately instructed personnel. Clearly establish which personnel are

� For specific jobs wear individual protective equipment (protective goggles, safety helmets, safetyshoes and gloves, reflective vests and ear protection etc...)..

� Ensure that you obtain information on any special safety regulations for the job site from the siteforeman.

� Always tilt up the safety lever before leaving the operator�s seat. � When getting in and out, do not hold on to the steering column, control panel or joystick. Doing

this could cause unintentional movement, which could result in an accident. � Never jump from the machine; use the steps, ladders, gangplanks and supporting straps provided

for this purpose. � Face the machine when getting in or out and always use three-point support, i.e. two hands and

one foot or two feet and one hand must always be in contact with the access system at the sametime.

� Familiarize yourself with the location of the emergency exit out of the cab. � In the absence of any other instructions, proceed as follows for all maintenance and repair work:

� switch off the machine on firm, level ground� align the uppercarriage with the undercarriage so that the sprockets locate at the back-end� anchor the grab in the ground.� place all operating levers into neutral and tilt the safety lever up. � switch off the engine and remove the start key.

� Before touching any parts of the hydraulic circuits, you must also operate all pilot control devices(joystick and pedals) in all directions with the start key in contact position and with the securitylever lowered, in order to reduce the actuating and dynamic pressures in the work circuits. Youmust then reduce the internal tank pressure as described in these operating instructions.

� Secure all loose parts on the machine. � Never operate a machine before carrying out a careful inspection tour and checking whether any

warning signs are missing or illegible. � Respect all danger and safety instructions.� For special applications the machine must be equiped with specific safety equipments. Work only

if they are mounted and functional.� Do not carry out any modifications, alterations or conversions to the machine which may affect

safety without the express permission of the manufacturer. This also applies for the installation ofsafety devices and valves and for welding work on load-bearing parts.

� It is forbiden to repair the structure of the cab.� Not original equipment and component parts or such kind, wich has generaly not been validated

by LIEBHERR for installation or extension, has not to be installed or added onto the excavatorwithout previous written agreement of LIEBHERR. Wherefore the necessary technical documen-tations has to be at LIEBHERR�s disposal.

Avoidance of crushing and burns� Do not work beneath the equipment if it is not safely positioned on the ground or supported. � Do not use any damaged or insufficient load-bearing take-up materials, such as ropes or chains. � Wear work gloves when working with wire cables. � When working on the equipment, never use your fingers to locate bores; use the correct punch for

the procedure. � Ensure that no objects enter the fan when the engine is on. The fan will eject or destroy these

objects and will itself be damaged. � The engine cooling system is hot and pressurized when near operating temperature. Avoid com-

ing into contact with coolant carrying parts. There is a risk of sustaining burns. � Only check the coolant when the sealing cap of the expansion container has cooled to a point

where it is possible to touch it. Then turn the cap carefully to let off the overpressure.

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 toavoid damage when the hoe teeth come within this area.

� Depending on the equipment combination, there is a risk of collision between the lift ring of theattachment and the cab or the cab protection. Before operating, ensure that there is no risk of col-lision, 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 from 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 thestorm.

� Auxiliary control units can have various functions. Always check their functions when starting upthe machine.

� Stop the swinging motion of the uppercarriage when lowering the attachment into a ditch withoutstriking the attachment on the ditch walls.

� Inspect the machine for damage if the attachment has been swung into a wall or any other obsta-cles.

� Applications in which the attachment is to be used to strike the material being extracted are notpermitted, even when working in a longitudinal direction.

� Repeated strikes against an object leads to damage to the steel structures and machine compo-nents.

� Please refer to your LIEBHERR dealer if special teeth for heavy-duty or special applications arerequired.

� Do not attach too large bucket or bucket with side cutters or that are during operations with rockymaterial. This would prolong the work cycles and may lead to damage to the bucket as well asfurther machine components.

� With the 2x45° offset articulation, the offset position may only be employed if the working tool orthe attachment does not touch the material.

� Operation of the offset articulation to drill into the material is not permitted.� Do not lift the 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 forbidden 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 dam-aged.

� 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 wind-

shield 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 re-

traction and extension motions of the hydraulic hammer.� Do not apply the hydraulic hammer uninterrupted for more than 15 secs. at a time to the same

place. Change the breaking point. Too long uninterrupted operation of the hydraulic hammer leadsto 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 moveobstacles with the hydraulic hammer. Misuse of this nature would damage both the hammer andthe machine.

� Do not use the hydraulic hammer to lift objects

Safe use when loading and unloading (particularly when loading and unload-ing wood)

� According to use, it can be necessary when working with a grab to move with the equipment raisedand 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. Thedriving characteristics of the machine will thus be influenced persistently, e.g. through reductionof the dynamic stability. The following instructions are therefore to be observed at all times: � Adjust vehicle handling to suit the altered machine characteristics and environmental condi-

tions. � 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 struc-

ture 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 there is a risk of

objects falling from above. � Only the maximum permissible load may be taken up using the grab.

� NOTE: The weight of absorbent materials, such as logs, is dependent on length, diameter andspecific weight. The influencing variables present in a natural product, such as moisture, must benoted.

� Working procedures when using machines with grabs require the machine operator to receivespecial instruction and training.

� Use as part of the work process is only permitted when the machine operator has sufficient train-ing 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 per-sistently, e.g. through reduction of the dynamic stability.

� Due to the heightened centre of gravity, the machine must be aligned horizontally before use. Inhorizontal alignment, the centre of gravity of the upper structure is over the centre of the under-carriage, 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 une-

ven 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 mobile 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, brakes, controlling the machine�s control elements

when driving and working. � To a large extent, the machine operator determines the vibrational loads since he selects the

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 recommenda-tions 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 exca-

vators, this should be a seat which corresponds with EN ISO 7096). � 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 theoperator.

� Check the seat�s damping action and adjustment mechanisms regularly and ensure that theseseat 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 suf-

ficient 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 fre-

quently. 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 instruc-

tions.� 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 besecured 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 manufac-turer�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 lurch-

ing.� After towing, return the machine to correct operational status.� When restarting the machine, be sure only to proceed in accordance with the operating instruc-

tions.

Attaching and removing equipment parts safely� Equipment or attachments made by other manufacturers or those which do not have general ap-

proval from LIEBHERR for installation or attachment may not be installed or attached to the ma-chine without LIEBHERR�s prior written consent.

� LIEBHERR must be provided with the appropriate technical documentation necessary for this pur-pose.

� Before carrying out any major repair work on the equipment, position the machine on level, firmground.

� Do not work beneath the equipment if it is not safely positioned on the ground or supported withwooden blocks.

� Before loosening lines or unscrewing bolts, you must store the equipment, switch off the engineand press the start key to the contact position and both joysticks and the pushbuttons to �Turngrab� in order to reduce the pressure in the hydraulic system.

� Do not attempt to lift heavy parts. Use devices which are suitable for this purpose and which havesufficient load carrying capacity.

� Do not use cable which is damaged or does not have sufficient load carrying capacity. Wear workgloves when working with wire cables.

� When working on the equipment: switch off the engine and keep the safety lever tilted up. Neveruse your fingers to locate bores; use the correct punch for the procedure.

� During repair work: ensure that the hydraulic lines are secured correctly and that all bolts and con-nections are tight.

� When you have removed and chocked an equipment part, close open areas of the hydraulic circuitto stop dirt entering. Only allow authorized persons in the vicinity of the machine or the lifting de-vice used.

Removing and installing equipment bolts safely � If possible, always use a hydraulic bolt press to press out the equipment�s bolts.� If you have to remove a bolt using a sledge-hammer, a driving punch and a bore hole conductor

held by another person must be used. � To drive in a bolt, screw the drive screws provided in the toolbox into the bolt's threaded hole and

only hammer these screws. � When installing bolts locked by means of castle nuts and cotter pins, first drive the bolt to the stop,

then screw the castle nut by hand until contact and then only pull it far enough to push in the cotterpin.

Transporting the machine safely� Due to transport restrictions, use only suitable means of transport and lifting devices with sufficient

load-carrying capacity. � Park the machine on a flat surface and wedge the crawler or wheels securely. � If required, detach a part of the machine�s working equipment during transportation.

� Cordon off a wide maintenance area if required. � Inform operational personnel before starting to carry out any special work and repair work. Desi-

gnate persons in charge of supervision. � In the absence of any other information in the operating instructions, carry out all maintenance

work on the machine on level, firm ground with the working equipment set aside and the engineswitched off.

� For some machines, the only one position which enables a secured access to every maintenancelocations on the uppercarriage, is when the uppercarriage is aligned with the undercarriage so thatthe sprockets locate at the back-end.The ladder situated on the undercarriage only corresponds with the uppercarriage�s access whenthe excavator is in this configuration.

� Pull out the ignition key and shut off the main battery switch. � Always tighten any loose screw connections during maintenance and repair work.� The mounting bolts of the main components, of the hydraulic hoses and of the counterweight must

be replaced after every removal.� If safety devices have to be dismantled during set-up, maintenance and repair work, they must be

immediately reinstalled and checked at the end of the work. � When carrying out repair work, particularly when working under the machine, hang a �Do not start�

warning sign in a clearly visible position on the starting lock. Pull out the start key and shut off themain battery switch.

� Operate combustion motors and fuel operated heaters only in well ventilated areas. Before ope-rating these units, check ventilation.

� In addition, always follow applicable local regulations.

Cleaning� Clean oil, fuel or care products off the machine before starting maintenance or repair work and

pay particular attention to connections and screw fittings. Do not use aggressive cleaning products and use lint-free cleaning cloths.

� Do not use aggressive cleaning products or steam jet devices to clean the machine for the firsttwo months after initial set-up of the machine (or after repainting).

� Do not use combustible liquids to clean the machine. � Before cleaning the machine with water or steam jets (high pressure cleaner) or other cleaning

materials: � lubricate all bearing points, bolt connections and the rim bearing to prevent water or steam en-

tering the bearing points. � cover or glue shut all openings into which for safety or functional reasons water or steam may

not be permitted to enter. Electric motors, electrical components, control boxes, plug connections and air filters are partic-ularly at risk.

� Ensure that the fire warning systems and fire extinguishers of the engine compartment�s temper-ature sensor do not come into contact with hot cleaning products during cleaning work. The fire extinguisher could start.

� If you use a high pressure cleaner with steam or hot water to clean the machine, observe followingrecommendations :� the distance between the nozzle and the surface to be cleaned must be no lower than 20 inches� the water temperature should not exceed 60°c (140°F)� limit the water pressure to 80 bar maximum (11500 PSI)� if you employ cleaning fluid, only use neutral cleaning agents such as customary car shampoos

� After cleaning: � remove all covers completely.� check all fuel, engine oil and hydraulic lines for leakage, loosened connections, chafing and

damage. � rectify any defects found immediately. � lubricate all bearing points, bolt connections and the rim bearing to displace any water or clean-

ing products that may have entered.

Crack testing� Even when the machine is operated carefully, there is a possibility of individual cases of overload-

ing occurring, which could lead to cracks or loose connections. The machine should therefore bechecked regularly for cracks, loose connections or other visible damage to maintain operationalsafety.

� In order to be able to check for cracks, it is essential that the machine is kept clean and cleanedregularly.

� The tests should be carried out in accordance with the monitoring and maintenance plan: � every 250 operating hours by the machine owner�s maintenance personnel. � every 500 operating hours by authorised specialist personnel.

� It is advisable to carry out these tests: supported, on firm, horizontal substrate, with the equipmentin longitudinal and cross direction for variable loads. Current accident prevention regulations mustbe adhered to.

� Special care must be taken when testing load-bearing components, particularly: � the steel chassis members and axle and transmission mountings, the support, the lower rim

bearing support and tower and ball rim bearing. � the steel upper structure members and bearing block for boom and boom cylinder, the upper rim

bearing support, the cab mount and the mount for swing gear and ballast.� the steel components of the working equipment, e. g. the boom, stay, quick change adaptor, and

bucket. � hydraulic cylinders, axles, steering, bolts and bolt connections, steps, ladders and mounting el-

ements. � The crack test should be carried out visually. If a crack is suspected, the dye penetration test

should be carried out as a crack test on areas which do not have good visibility, such as the rimbearing support, in order to increase testing safety.

� Any damage found must be rectified immediately. Welding work on load-bearing parts of theearth-moving machinery, loading devices and transport devices may only be carried out by trainedspecialist personnel and only in accordance with the accepted rules of welding engineering. Incase 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 rule is neglected, the warranty isvoided.

� 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 negativeterminal first and reconnect it last.

� Nevertheless if welding repair should be done on components which may contain inflammablegases (welded counterweight, hydraulic tank, fuel tank, �), these components must be previouslyand 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 weldingcurrent 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 environmen-

tally acceptable manner. � Take care when handling hot process materials

(Risk of burning and scalding).

Repair work� 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 securethem on lifting devices them so that they do not present a risk. Only use suitable and correctlyfunctioning 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 attach loads and give signals to the crane operator. Thespotter 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 ap-propriate 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 thatpneumatic 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). Preventmetal touching metal when doing this.

� For safety reasons, never open and remove a track chain unless having previously totally re-leased the pretension of the chain tensioning unit.

� Never lay under the machine if it is raised with work equipment and has not been securely sup-ported with wooden beams.

� Always jack the machine up in such a way that any weight displacement does not jeopardize sta-bility and prevent metal touching metal while doing this.

� Work on the suspension, brake and steering systems may only be carried out by trained specialistpersonnel.

� If the machine has to be repaired on a slope, secure the crawler with chocks and connect the up-per structure to the chassis using stop bolts.

� Only personnel with special training and experience may work on hydraulic equipment. � When searching for leakage, wear protective gloves. A fine jet of liquid under pressure can pen-

etrate the skin. � Do not unscrew any lines or connections before you have set aside the equipment, switched off

the engine and depressurized the hydraulic system. After switching off the engine, with the startkey in contact position and with the safety lever down into its lowest position, you must operate allpilot control devices (joystick and pedals) in all directions in order to reduce the actuating and dy-namic pressures in the work circuits. You must then reduce the internal tank pressure as de-scribed in these operating instructions.

Electrical system� Check the electrical system regularly.

Have all faults, such as loose connections, blown fuses and lamps and clogged or abraded cablesrectified by personnel.

� Only use original fuses with approved current strength.

� For machines with electrical neutral and high tension leads: � switch the machine off immediately in the event of malfunctions in the power supply.

� Work on the machine�s electrical equipment may only be carried out by skilled electrical personnelor by trained personnel under the supervision of an electrician in accordance with electrical regu-lations.

� When working on live parts, ensure that a second person is available to operate the emergency-off or the main switch and overvoltage release. Cordon off the working area with a red and whitesafety chain and a warning sign. Only use insulated tools.

� When working on neutral and high tension subassemblies, after releasing the voltage, briefly dis-connect the supply cable at earth and electronic devices such as capacitors using an earthing rod.

� First test the released parts to make sure that they are off circuit, earth them and then disconnectthem briefly. Insulate adjacent live parts.

� Disconnect the battery before working on the electrical system or carrying out any electric arcwelding on the machine. First disconnect the negative, then the positive pole. When reconnecting, proceed in the reverseorder.

Hydraulic accumulator� All work on the hydraulic accumulators must be carried out by trained specialist personnel. � Inexpert assembly and handling of hydraulic accumulators can cause serious accidents. � Do not operate damaged hydraulic accumulators. � Before working on a hydraulic accumulator, you must reduce the pressure in the hydraulic system

(hydraulic system including hydraulic tank), as described in these operating instructions.� Do not carry out welding or soldering or do any mechanical work on the hydraulic accumulator.

The hydraulic accumulator can be damaged by heat penetration and can be made to rupture bymechanical working. RISK OF EXPLOSION!

� Only charge the hydraulic accumulator with nitrogen. There is a RISK OF EXPLOSION if oxygenor air is used.

� The accumulator body can become hot during operation; there is a risk of burning. � 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 ac-

cumulators. Ensure that this marking remains visible.

Hydraulic hoses and sheathed cables. � It is forbidden to carry out repair work on hydraulic hoses and sheathed cables! � All hoses, sheathed cables and bolt connections must be checked regularly 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 nat-

ural 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, wheth-

er 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-pres-sure hoses, the screws from the half-clamps or full flange must always be attached to both hoseends and should only be tightened afterwards.

� When tightening the flange on high-pressure hoses and sheathed cables with bent fittings, theside with the bent fitting must always be tightened first and then the side with the straight fittingtightened afterwards.

� Any mounting clamps which are located in the centre of the hose may only be attached and tight-ened subsequently.

� Check daily to ensure that all clamps, covers and protective devices are properly fastened. Do-ing this will prevent vibration and damage during operation.

� Install the hoses and sheathed cables in such a way that they cannot chafe on other hoses,sheathed cables or parts.

� A minimum distance from other parts of approx. half the exterior diameter of the hose is recom-mended. 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.

1.22: Assembly instruction for pistons and piston nuts (hydraulic cylinders)

According to standard WN 4121 B (04/2005)

1 Scope of applicationThis factory standard applies exclusively to the assembly of hydraulic cylinders with a thread diame-ter of M42 and greater. For the valid factory standard number, refer to the drawing. The standard maynot be adopted or transferred to apparently similar geometries.

The torques have been determined empirically and are subject to changes. THe revision and release dates indicate the latest version of the factory standard.

For threads with diameters smaller than M42, the applicable tightening torques are indicated in the drawings.

The values in the drawings are always binding.

2 Description

Preparation :

Clean the contact surfaces (threads contact faces between piston rod, piston and piton nut) and apply a thin layer of Gleitmo high-performance lubricating grease (ID no. 8300 004, 40 g tube) on both sides.

2.1 Definitions :

Pretightening torque :

The piston is secured with a torque wrench applied to the square / hexagon head of the assembly wrench. The position of the torque wrench must be carefully noted.

Fig. 1 Torque wrench

When applying the pretightening torque, the torque wrench must point in the same direction as the assembly wrench.

Proceed in the same w<ay to tighten the piston nut, using a suitable assembly wrench.

Scope of application

This factory standard applies exclusively to the assembly of hydraulic cylinders.

For the valid factory standard number, refer to the drawing. The standard may not be adopted ortransferred to apparently similar geometries.

The torques have been determined empirically and are subject to changes. THe revision and release dates indicate the latest version of the factory standard.

1 Description

Preparation:

Clean the thread and apply a thin layer of Gleitmo high-performance lubricating grease (ID no. 8300 004, 40 g tube) on both sides.

1.1 Definitions

Pretightening torque:

The piston rod bearing is secured with a torque wrench applied to the square of the assembly wrench. The position of the torque wrench must be carefully noted.

Fig. 1 Torque wrench

When applying the pretightening torque, the torque wrench must point in the same direction as the assembly wrench.

Turning distance:

Radian measure [mm] between the bearing head outer diameter and the cylinder tube, tavelled after application of the pretightening torque.

Turning angle:

Angle [°] travelled by the bearing head after application of the pretightening torque.

Preloads and tightening torques (Din 13)

2 Angle tightening processThe angle tightening process constists in rotating the screw from a defined angle in order to enable the screw elastic lenghtening and the plates tightening. A tightening torque predetermined according to the screw size, will bring this screw on block against the parts to tighten, in order to determine the beginning of the tightening angle mesure.

From this value 0=0, the preload force is set up regardless of the thread friction coefficient or of the bearing surface, simply by rotating the screw by retightening angle .

Example 1 :

Screw M14 - 10.9, clamping lenght Lk = 80mm;

According to the table, for the 10.9 class:

Preloads MA = 50Nm; Retightening angle ~ 45°

Example 2 :

Screw M24 - 12.9, clamping lenght Lk = 100mm;

According to the table, for the 12.9 class:

Preloads MA = 160Nm; Retightening angle ~ 57°

2 Lubricant Chart

Note!The filling amounts specified in the fuel and lubricants chart, as well as in the lubrication chart, are reference values only.

After performing an oil-change or top-up, always check the level in the respective aggregate.

Note!Conscientious adherence of the guidelines for lubrication, checking levels and replacing fuels will guarantee increased reliability and life-expectancy of the machine. Particular attention must be paid to the intervals for oil-changes and it is imperative that the stipulated lubricant qualities are adhered to.

Note!Cleanliness is extremely important when carrying out oil-changes.

Clean all filling screws, filler caps and drain plugs, including their immediate surroundings before opening them.

Always ensure that the oil is at operating temperature before draining.

Ensure that used oils are collected and disposed of in an environmentally-friendly manner along with the removed oil filter cartridges.

Danger!It is imperative that the following guidelines are observed when inspecting or changing fuels and lubricants:

Unless otherwise specified, carry out the respective work on the machine on firm, level ground with the engine switched off.

Always secure the cover against falling or closing before leaning into the engine room.

Refuelling may only be carried out with the engine switched off, never smoke and avoid naked flames.

4 FuelDiesel fuels should comply with the minimum requirements of the permissible fuel specifications stip-ulated below.

4.0.1 Lubricity / sulphur contentIn DIN EN 590 a max. 350 mg/kg = max. 0.035 wt% sulphur content permissible.

�Low-sulphur� diesel fuels with a sulphur content below / less than 0.05% are only permissible if alubricity can be guaranteed with the addition of additives. The diesel fuel lubricity must be 460 µm inaccordance with HFRR (60) Testmax. [lubricity amended �wear scar diameter� (1.4) at 60 °C].

For diesel fuels with a sulphur content above / more than 0.5 wt%, the oil-change intervals areto be halved.Diesel fuels with a sulphur content above / more than 1% are not permissible.

4.0.2 Permissible fuel specificationsDIN EN 590

ASTM D 975 - 89a 1 D and 2 D

Further fuel specifications can be obtained upon consultation with LIEBHERR's diesel engine devel-opment department.

4.0.3 Diesel fuel at low temperatures (winter operation)Paraffin crystals become separated in the diesel fuel as ambient temperatures fall. This causes asubsequent flow resistance in the fuel filter and a sufficient supply of fuel to the diesel engine can nolonger be guaranteed. In moderate climates, optimum flow flexibility can be guaranteed up to:

0 °C from 15.04. to 30.09.

-10 °C from 01.10. to 15.11. and from 1.3. to 14.04.

-20 °C from 16.11. to 29.02.

in accordance with DIN EN 590. We recommend using a fuel filter heater wherever flow flexibility ofthe diesel fuel proves inadequate, or when working in ambient temperatures below -20 °C. Other ap-proved diesel fuels:

Diesel fuel in compliance with DIN EN 590 with up to 5% Vol. FAME.

Note!An approval can be granted in correspondence with the quality of the diesel engine lube oil! Fuel standard ASTM D 975 does not stipulate that the fuels must pass a fuel lubricity test. A written con-firmation from the fuel suppliers must be acquired. The additives must be added by the supplier in his capacity as sole responsible agent for quality of the fuel. The addition of secondary lubricity ad-ditives by the customer is not recommended.� A cetane number of at least 45 is required for fuels in accordance with ASTM D 975. A cetane

number above 50 is recommended, particularly when working in temperatures below 0 °C or32 °F.

Caution!Improving flow of the diesel fuel by adding petroleum or regular benzine, or flow improvers from al-ternate manufacturers which can be readily purchased in stores, even in insignificant quantities, is absolutely prohibited. Such an addition is not compatible with the high-pressure injection system of your diesel engine and would lead to ruination of the diesel engine as a direct result of inadequate lubrication.

To avoid premature wear of the hydraulic components, the oil-change intervals (or the intervals sep-arating the taking of oil samples) are to be reduced and the following guidelines are to be observed:

� The filter cartridge(s) in the return-flow filter must be replaced every 500 operating hours� For the return-flow filter, 10-µm filter cartridges must be used instead of the regular 20 / 5-µm filter

cartridges� The ventilation filter on the hydraulic oil tank is to be replaced with a 2 µm fine filter (refinement of

the standard filter is 7 µm)� The 2-µm ventilation filter is to be replaced each time a hydraulic oil-change is performed (every

500 operating hours)

5.0.7 Gear oilGear oils must comply with the specifications� API-GL-5 and MIL-L-2105 B or C or D for viscosity class SAE 90

For viscosity classes SAE 80 and SAE 90 in accordance with MIL-L-2105 D, oils of viscosity classSAE 80W90 may also be used.

Lubricating grease and other lubricants

6 Coolant

6.0.1 Anticorrosive and antifreeze with DCA (ID no. 8503890 - 30 l drum)Water filter accessories are introduced to LIEBHERR diesel engines to improve quality of the coolingwater.

This allows a supplementary filtering of the coolant in the bypass flow where it is purified of dirt or rustparticles which could cause leakages in the cooling pumps.

Additionally, a chemical admixture in the filter (DCA 4) protects the cooling system, or parts whichcome into contact with the coolant such as coolant pumps, cylinder liners etc. against cavitation, cor-rosion, limescale and the build-up of foam.

Four different water filter accessories have been implemented due to the diverse volumes of coolingwater or diverse water accessories on engines or equipment.

6.0.2 Coolant with DCA 4 (DIESEL COOLANT ADDITIVES)

Tab. 7 Mix ratio of water / anticorrosive / antifreeze

The coolant must comprise at least 50 vol-% of anticorrosive and antifreeze all year round. This cor-responds with a freeze protection down to -37 °C and guarantees ample protection against corrosion.

In the event that coolant is disappearing at an unusual rate, ensure that the minimum 50 vol-% is be-ing adhered to when refilling.

The mix ratio and the DCA 4 concentration must be checked when carrying out the maintenancetasks.

6.0.3 AnticorrosiveIn exceptional cases and if ambient temperatures are continuously above freezing point, e.g.in tropical regions, in which no approved anticorrosive /antifreeze is readily available, a mixtureof water and water-based anticorrosive may be used as coolant.

Utilisation of DCA 4 without anticorrosive / antifreeze

To protect the cooling system from corrosion, approximately double the amount of DCA 4 must beadded to achieve the same mix ratio of water and DCA 4 (see Tab. 7).

Ambient temperatures up to Percentage (%) of water Percentage (%) of anticorrosive / antifreeze

-37 °C / -34 °F 50 50-50 °C / -58 °F 40 60

Note!Do not use more than 60 % anticorrosive and antifreeze! Cooling effect and freeze protection will be minimised if higher percentages are added.

Note!� The coolant is to be changed every 2 years.� The DCA 4 concentration must total between 0.3 and 0.8 units per litre.� Test kit CC 2602 M from Fleetguard is recommended for checking.
