3.4 Working with the machine 3.4.1

Working with the machine safely – Before starting to work, familiarize yourself with the peculiarities of the job site, the special regulations and warning signals. Part of the surrounding area includes, for example, the obstacles in the working or movement area, the load carrying capacity of the ground and required safeguards for the job site to shield it from public highway traffic.

– Always keep an adequate safety distance to overhangs, edges, embankments and an unsecured substrate.

– Be particularly cautious in conditions of reduced visibility and changing ground conditions.

– Familiarize yourself with the location of power lines on the job site and work particularly careful in their vicinity. If necessary, inform the responsible authorities.

– Maintain a safe distance from electrical overhead lines. Do not approach the line with the equipment when working near electrical overhead lines. Danger of fatal injury! Inform yourself about required safety distances.

– In case of a flashover, proceed as follows: • do not move the machine or its attachment, • do not leave the operator’s platform,

Working with the machine

• warn people in the vicinity not to approach or touch the machine, • have the power turned off.

– Before moving the machine, always ensure that the attachments are safely secured.

– When travelling on public roads, paths or squares, observe the valid traffic regulations and, if necessary, first bring the machine into proper condition to meet federal and local highway standards.

– Always turn on the lights in conditions of poor visibility or darkness.

– Do not permit any passengers on the machine (except on two way excavators).

– Operate the machine only when seated and with the seat belt fastened.

– Report any problems or needed repairs and make sure that all required repairs are carried out immediately.

– Personally make sure that no one is endangered by moving the machine.

– Before starting to work, always check the brake system as outlined in the operating manual.

– Never leave the operator’s seat as long as the machine is still moving.

– Never leave the machine unattended while the Diesel engine is running.

– The machine must be utilized, driven and operated in such way that the stability is ensured and that there is no danger of tipping over. Only known loads may be moved with the attachments, especially in grapple operation.

– The maximum approved passable incline / traverse slope of the machine depends on the attached equipment as well as the substrate.

– For travel, move the uppercarriage in lengthwise direction and hold the load as close as possible to the ground.

EXCEPTION: see WHEN LOADING AND UNLOADING – Adjust the travel speed to suit local conditions.

– Avoid working movements which could cause the machine to tip over.

– If possible, always work downhill or uphill, never sideways on a slope.

– Only travel downhill at the permitted speed or you could loose control over the machine.

– Only drive downhill at a low driving speed, since you may otherwise loose control of the machine. The Diesel engine must run in the upper revolution range and be reduced by selecting the low driving speed range / the lowest gear.

– Before travelling downhill, always shift to a lower gear. When doing this, the Diesel engine must run at maximum RPM and the speed may only be reduced using the accelerator pedals.

– When loading a truck, make sure that the truck driver leaves the cab, even if a rock protection is present.

– Always use the safety devices intended for their specific use for demolition work, clearings, hoisting operations, etc.

– For terrain which is difficult to gain an overview of and whenever necessary, ask for assistance of a guide. Have only one person signal you.

– Only permit experienced personnel to secure loads and signal the machine operator. The guide must position himself within view of the operator or be in voice contact with him.

– Depending on the attachment combination, there can be a danger of collision between the working tool and the operator’s cab, the cab protection or the boom cylinders. To avoid damage, utmost attention is required when the bucket teeth enter this range.

Operating instructions

Control, operation Working with the machine

3.4.1.1

Safe application in material handling operation (especially when handling timber) – Particularly when working with a grapple it can be necessary to move the machine with a raised attachment and picked up load, for example when handling wood or timber.

– This will shift the center of gravity of the machine upward in vertical direction. The travel behaviour of the machine will be strongly influenced, for example reduction of dynamic stability.

For that reason, the following rules must be strictly observed: • Match your travel behaviour to the changed machine characteristics and surrounding conditions.

• Reduce the travel speed to avoid sudden braking or steering manoeuvres.

• Avoid sudden speed changes, such as braking, acceleration, changes in travel direction.

• Turn the uppercarriage only if the undercarriage is stationary.

• Turn the uppercarriage only after taking on the load.

• Move the machine only after you have taken on the load, lifted it and turned the uppercarriage in travel position.

• If the attachment is raised, there is a danger due to possible oscillating movements and falling of the picked up load.

• A protective screen (FOPS) according to ISO 10262 must be attached on the front on the cab.

• The protective screen (FOPS) according to ISO 10262 must be installed if there is a danger of falling objects from overhead.

• Only the maximum permissible load may be picked up with the grapple.

– NOTE: The weight of absorbent material, such as wooden logs, depends on the length, the diameter and the specific weight. The existing influencing factors for a natural product, such as moisture, must be considered.

– The working sequences when working with machines with grapples require special instruction and training of the machine operator.

– The work application is only permitted after the machine operator has received sufficient training and practical experience.

3.4.1.2

Safe application of machines with tower elevation – Due to the tower elevation, the center of gravity of the machine will shift upward in vertical direction. The travel and work behaviour of the machine will thereby be strongly influenced, for example reduction of dynamic stability.

– Due to the elevated center of gravity, the machine must be aligned in horizontal direction before starting to work. In horizontal direction, the center of gravity of the uppercarriage is above the center of the undercarriage, which reduces the danger of tipping over.

– The machine can rock despite leveling and tip over!

For that reason, the following rules must be strictly observed: When driving the machine: • Swing the uppercarriage parallel to the undercarriage (transport position).

• Pull the attachment as close as possible to the machine.

• Only then may the outriggers be retracted and the machine be driven.

• Driving with loads is not permitted.

• Check the roadway to ensure the ground is solid and even! Pot holes and uneven road surfaces endanger the stability of the machine.

• Match your travel behaviour to the changed machine characteristics (higher center of gravity) and surrounding conditions.

• Reduce the travel speed to avoid sudden braking or steering manoeuvres.

• Avoid sudden speed changes, such as braking, acceleration, changes in travel

direction.

• Drive uphill and over obstacles only in lengthwise direction, to avoid impermissible transverse slopes of the machine.

• Special care must be taken when driving through narrow passages – drive slowly!

In material handling operation: • Before moving (turning) the uppercarriage from transport position, the machine must be supported and horizontally aligned.

• Make sure to check the placement surface of the outriggers (load carrying capacity of ground). Sinking of an outrigger below ground level would result in devastating consequences!

• Carry out all movements with increased caution.

• To turn a load, move the attachment as close as possible to the machine (Caution! Oscillating grapple), while holding the load as close as possible to the undercarriage and above the ground.

• Avoid abrupt slow down or acceleration of the attachment or uppercarriage.

• Never lift a heavier load than stated in the load chart.

3.4.1.3

Additional notes for machines with fixed operator’s cab elevation – To enter and exit the machine, park the machine on ground, which is level in lengthwise and horizontal direction. Position the uppercarriage to the undercarriage in such a way that the steps and ladders are aligned.

– Keep steps, ladders and handholds (handles) in proper condition. Make especially sure that they are free of dirt, oil, ice and snow.

NOTE: To ensure that the doors open in all weather conditions, lubricate the weather strips at least every two month, or more often, if necessary, with talcum powder or silicon. Lubricate the door hinges and locks regularly.

– When entering or leaving the machine, always face the machine and use the three point support, i.e. always have two hands and one foot or two feet and one hand in contact with the entry system.

– When you can reach the door handle with the free hand, open the door first before climbing higher. External influences, such as wind, can make it more difficult to open the door. For that reason, always guide the door by hand when opening the door. Make sure that the door is engaged when it is open, to prevent it from banging open or closed.

– Continue to climb up and immediately sit on the operator’s seat in the cab. Then close the door and fasten the safety belt.

– Proceed with the same care when exiting and climbing down as when entering and climbing up the machine.

– Park the machine only on firm and level ground. Position the uppercarriage to the undercarriage in such a way that the steps and ladders are aligned.

– Release the safety belt. When exiting, face the machine and use the three point support. Climb down until you can close the door safely. Always guide the door by hand when closing the door.

– Finally climb down to the ground.

3.4.1.4

Protection from vibrations – The vibration impact on mobile construction machinery is usually the result of the manner of utilization. Especially the following parameters have a significant influence: • Terrain conditions: Unevenness and potholes; • Operating techniques: Speed, steering, braking, control of operating elements of the machine during travel as well as working.

3 - 48

MJFCIFSS

A 316 Litronic Industrie / 8720370

Operating instructions

Control, operation Working with the machine

– The machine operator determines the vibration impact to a great part, since he himself selects the speed, the gear ratio, the working manner and the travel route.

This results in a wide range of various vibration impacts for the same machine type.

The full body vibration impact for the machine operator can be reduced if the following recommendations are observed: – Select the appropriate machine, equipment parts and auxiliary devices for the corresponding tasks.

– Use a machine equipped with the appropriate seat (i.e. for earth moving machines, for example hydraulic excavators, a seat which meets EN ISO 7096).

– Keep the seat in good order and adjust it as follows: • The seat adjustment and the suspension should be made according to the weight and the size of the operator.

• Check the suspension and the adjustment mechanism regularly and make sure that the characteristics of the seat remain as specified by the seat manufacturer.

– Check the maintenance condition of the machine, especially regarding: Tire pressure, brakes, steering, mechanical connections, etc.

– Do not steer, brake, accelerate and shift or move and load the attachment of the machine in a jerky manner.

– Match the machine speed to the travel route to avoid vibration impacts.

• Decrease the speed when driving on pathless terrain; • Drive around obstacles and avoid very impassable terrain.

– Keep the quality of the terrain where the machine is working and travelling in good order: • Remove large rocks and obstacles; • Fill furrows and holes; • To establish and retain suitable terrain conditions, keep machines available and allow for sufficient time.

– Travel longer distances (i.e. on public roads) with suitable (medium) speed.

– For machines, which are frequently used for travel, utilize special auxiliary systems for travel (if installed), which reduce the vibration for this application.

If such auxiliary systems are not available, regulate the speed to keep the machine from "rocking".

3.4.13 3.4.13.1

Overload warning device General The overload warning device shows the machine operator when the permissible load carrying capacity has been reached, both optically via the indicator light H16 and acoustically, via a buzzer.

The overload warning device is designed to prevent the permissible load level from being exceeded unintentionally. In this event, the working range must be reduced or the load must be set down without increasing the working range.

The overload warning device does not relieve the operator of the responsibility of lifting only known loads or permissible loads, based on the load carrying capacity of the machine.

The permissible load carrying capacity depends on the condition of the machine (undercarriage, attachment) and must be taken from the load chart in the cab.

The load carrying capacity values attain a maximum of 75% of the tipping capacity or 87 % of the hydraulic lifting power in accordance with ISO 10567.

Note!

The load values change due to the installation or removal of attachment parts and working tools.

For backhoe attachment (without the backhoe, incl. bucket cylinder, change over lever and connecting link) the values on the top of the stick apply. The machine can be turned by 360° on solid, level ground. If the bucket cylinder, change over lever and connecting link are removed, the values increase by an additional 240 kg. If a quick change adapter is used, the values are reduced by 116 kg (QCA 33) or 225 kg (QCA 48).

3.4.13.2

Operating principle Danger!

When carrying out load lifting work with the machine, the applicable accident prevention regulations must be observed.

The overload warning device does not shut down the machine if the permissible load level is exceeded. The machine operator is only informed of the situation.

The overload warning device consists of a simple pressure switch, which is connected to the piston side of the hoist cylinder.

If the load pressure in the hoist cylinder reaches the level of the shift pressure, the pressure switch emits a signal, the indicator light H16 lights up and the buzzer sounds.

The shift pressure in the pressure switch is selected in such a way that the stability factors can be maintained, even in unsupported condition (small stability momentum).

Using the quick change adapter for load lifting work

Fig. 3-71

Mechanical quick change adapter

The quick change adapter is equipped with two integrated load hooks. The machine may only be used for load lifting work if the safety devices required for this purpose are present and functioning correctly (see chapter “Load lifting work” or “Overload warning device”).

The maximum load carrying capacity of each individual load hook is stated on the quick change adapter. The load carrying capacity of the quick change adapter or the integrated load hook can exceed or fall below the load carrying capacity of the carrier machine.

During operation, make sure that the values given in the load chart and the technical data of the carrier machine are adhered to.

Load lifting work can be carried out with attached or removed working tools. With removed working tools, it is appropriate to fully retract the locking pins when carrying out lifting work. This prevents the load lift device from being deflected too strongly and damaged by the locking pins.

Danger!

Never use the pick-up hook 6 to fasten a load, because there is no secure hold for the load pick-up device, e.g. ropes or chains, in the pick-up hook.

Fasten the load on the load hook as described in the chapter “Load lifting work”.

Hydraulic quick change adapter (option) Safety instructions – Ensure that there are no persons in the attachment area during the installation and removal of the working tools. Move the work equipment as slowly as possible when attaching and dismounting a working tool.

Familiarize yourself with the control and operating principle of the quick change adapter before installing or removing any working tools.

– The proper function of the quick change adapter is monitored by a visual and acoustic warning device (buzzer and indicator light). The function of the warning device should be checked daily by operating the quick change adapter.

– If the buzzer and indicator light are activated without initiation of a deliberate locking or unlocking procedure, stop all work at once. If the buzzer and indicator light are not activated while a deliberate locking or unlocking procedure is being carried out, stop all work at once.

This could be caused by an uncontrolled position change of the locking pins, due to mechanical or hydraulic damage. A defect may also be present in the electrical system (e.g. proximity switch or buzzer).

Resume operation only after any defective parts have been repaired or replaced.

– The quick change adapter unlocks as soon as the switch / button designed for this purpose is pressed.

Always keep the working tool as close to the ground as possible during the unlocking procedure to avoid dangerous movements. Activate the quick change adapter only to carry out a deliberate locking or unlocking procedure.

– Each time a working tool is changed, the machine operator must ensure that the locking pins for the quick change adapter are inserted in the proper bore holes on the working tool and that the working tool is attached properly. Check visually to ensure that the working tool is tightly seated.

– In addition, carry out a work cycle with the tool, but only lift the tool to the point where the seating can be checked, for example the pin in the pin eye, by curling the bucket in and out.

– The load carrying capacity of the quick change adapter or the integrated load hook can exceed or fall below the load carrying capacity of the carrier machine.

During operation, make sure that the values given in the load chart and the technical data of the carrier machine are adhered to.

In addition, note the following: Before installation, remove the protective covers on the quick change adapter 1 and the working tool 2.

Always keep hydraulic couplings 3 and 4 clean.

Perform a visual check for cleanliness before installation. If necessary, clean all coupling parts and the sealing surfaces with a clean, oil-soaked cloth.

When changing a work tool, connect or disconnect the hydraulic coupling slowly.

When attaching the quick change adapter, tilt it until the coupling plates are connected due to the curb weight of the working tool.

Extend the locking pins.

If the plates do not connect as a result of curb weight, foreign objects (such as stones) may be the cause. In this case, clean all coupling parts to prevent damage when connecting.

The oil flow and pressure must be matched to the corresponding work tool.

When the work is completed, and particularly before transport, reattach the protective covers 1 and 2.

3.5.7.3

Installing LIKUFIX work tools to a quick change adapter without LIKUFIX It is possible at any time to attach a working tool with a LIKUFIX hydraulic coupling to a machine with a quick change adapter (mechanical or hydraulic).

Do not use a quick change adapter with a reinforcement kit, since the reinforced steel part 6 could damage the LIKUFIX hydraulic coupling on the work tool.

In this case, the quick-change adapter must be modified by LIEBHERR Service.

For installation without LIKUFIX hydraulic coupling, LIEBHERR work tools usually have an alternative connection option.

Example: On the ditch cleaning bucket, the hydraulic lines are either connected using LIKUFIX 4 or using an auxiliary hydraulic connection 5.

3.6 General working methods 3.6.1

Guidelines for minimum impact working methods To increase the service life of the machine and avoid unnecessary damage and resulting repairs, please observe the following points: – Do not stop the slewing motion of the superstructure when swinging into a ditch by stopping the attachment against the walls of the ditch.

– Avoid using the machine for applications where the attachment is knocked against the material to be removed, even lengthwise. Repeatedly hitting the work equipment against rocks or other hard material will lead to damage to the steel parts and machine components.

– In specific combinations of boom, stick and work tool, the work tool can hit or penetrate the cab. This could damage the cab and injure the machine operator.

– Do not attach buckets that are too big or side cutters when using the machine on rocky material. This will extend the work cycles and could result in damage to the bucket as well as other machine components.

– Please contact your authorized LIEBHERR dealer if special teeth for heavy or special applications are required.

– Operating the swing bearings to drill into material is not permitted.

– Do not lift up the machine when working. If this should occur, slowly lower the machine to the ground. Do not permit the machine to drop to the ground quickly and do not catch the downward movement with the hydraulics, since this could result in damage to the machine.

• check all fuel, engine oil and hydraulic lines for leaks, loose connections, chafing and damage.

• fix any defects immediately.

• lubricate all bearing points, pin connections and the swing ring, to displace any infiltrated water or cleaning fluid.

5.1.3

Crack inspection – Machines are subject to different loads, depending on application, job site, duration of use and conditions of use. The different load conditions result in the different service life durations for various machines components. This could lead to cracks and loose connections, particularly on load bearing parts. This applies particularly in the case of machines used in material handling or industrial applications or for machines with special equipment, such as demolition excavators. To ensure that operating safety is maintained, the machine must be checked regularly for cracks, loose connections or other visible damage.

– To check for cracks, it is necessary to keep the machine clean and to clean it regularly.

– The inspection must be carried out according to the inspection and maintenance schedule, • every 250 operating hours by maintenance personnel of the machine operator.

• every 500 operating hours by authorized expert personnel.

– It is advisable to carry out these inspections with the machine supported, on firm and level ground, at changing loads with the attachment in length and crosswise direction. The currently valid accident prevention regulations must be adhered to.

– Special care must be taken when inspecting load carrying components, especially: • The steel construction undercarriage with axle and gear mounting, support, lower swing ring seating with tower and ball swing ring.

• The steel construction uppercarriage with bearing block for boom and boom cylinder, upper swing ring seating, cab bearing, mounting of swing gear and counterweight.

• Steel components of working attachments, e. g. boom, stick, quick change adapter, digging tool and grapple.

• Hydraulic cylinder, axles, steering, pins and pin connections, steps, ladders and mounting elements.

– The inspection for crack must be made visually. To increase the level of inspection, if a crack is suspected or is in areas which are not easily visible, such as the swing ring seating, then the dye penetration procedure should be used to check for cracks.

– Any damage found must be fixed immediately. Welding on load bearing parts of earth moving machines, material handling and transport units may only be made by especially trained expert personnel and only in accordance to accepted regulation of welding technology.

Operating instructions

Maintaining the machine safely

– Wear protective gloves when checking for leaks. Fluid escaping from a small hole can have enough pressure to penetrate the skin.

– Do not loosen any lines or bolts before lowering the equipment, turning off the Diesel engine and relieving the hydraulic system. After the Diesel engine has been turned off, you must move all pilot controls (right handed joystick and pedals) into all directions to reduce the control pressure and the dynamic pressure in the work cycles. Then relieve the pressure in the tank, as described in this operating manual.

5.1.7

Electrical system – Check the electrical system regularly.

All defects, such as loose connections, burnt out fuses and bulbs, burnt or damaged wires or cables must be repaired immediately by an electrician or especially trained personnel.

– Only use Original fuses with the correct amperage.

– For machines with electrical mid and high voltage lines: • In case of problems in the electric energy supply, turn the machine off immediately.

– Only qualified electricians or trained personnel under the guidance and supervision of an electrician may work on the electrical equipment of the machine, according to the electro-technical guidelines.

– When working on live parts, work with a second person who can actuate the emergency off or master switch with voltage release. Rope of the work area off with a red and white safety chain and a warning sign. Use only insulated tools.

– When working on mid and high voltage components, shut off the voltage and connect the supply cable to the ground and ground the components, such as the condenser, with a grounding rod.

– Check all disconnected parts if they are truly free of current, ground them and short circuit them. Insulate adjacent, current carrying parts.

– Disconnect the battery before working on the electrical system or before carrying out any arc welding work on the machine.

Disconnect the negative pole first, then the positive pole. Proceed in reverse order when reconnecting.

MJFCIFSS

A 316 Litronic Industrie / 8720370

Operating instructions

Maintenance Maintaining the machine safely

– New pressure accumulators must be charged to the required pressure for the application before use.

– The operating data (minimum and maximum pressure) is marked permanently on the pressure accumulators. Make sure that the marking remains visible.

5.1.9

Hydraulic hoses and lines – Hydraulic lines and hoses may never be repaired!

– All hoses, lines and fittings must be checked regularly, every 2 weeks, in case of suspected intentional damage immediately for leaks and external visible damage!

Any damaged parts must be replaced immediately! Escaping oil can cause injuries and fires.

– Even if hoses are properly stored and used, they undergo a natural aging process. For that reason, their service live is limited.

• Improper storage, mechanical damage and impermissible use are the most frequent causes of failure.

• In regards to duration of use, the valid standards, regulations and guidelines for hoses and lines at the job site must be observed.

• Using hoses and lines close to the limit ranges of permitted use can shorten the service life ( for example in high temperatures, frequent work cycles, extremely high impulse frequencies, multi shift operation).

– Hoses and lines must be replaced when the following conditions are found during inspection: • Damage to the outer layer as far as the intermediate later (e.g. chafing, cuts and cracks); • Brittleness of the outer layer (hose material cracking); • Deformations, which differ from the natural shape of the hose or hose line, when under pressure or not under pressure, or in bends (e.g. separation of layers, blisters or bubbles); • Leaks; • Failure to follow installation instructions; • Damage or deformation of hose fittings, which reduce the strength of the fitting or the hose / fitting connection; • Hose slipping out of the fitting; • Corrosion on the fittings, which reduces function and strength; – When replacing hoses and lines, use only Original spare parts.

– Route and install hoses and lines properly. Do not mix up the connetions.

– When replacing hoses and lines, observe the following: • Always ensure that the hoses and lines are free of torsion when routing. On high pressure hoses, always attach the screws of half clamps or full flange on both ends of hose first and then tighten.

• When using high pressure hoses and lines with a bent fitting, always tighten the end with the bent fitting first when tightening the flanges, then the end with the straight fitting.

• Any existing mounting clamps in the center of the hose may only be installed and tightened thereafter.

• Check daily to ensure that all clamps, covers and protective devices are properly mounted. This prevents vibration and damage during operation.

• Route the hoses and lines in such a way that chafing with other hoses or other structures is prevented.

• A minimum distance of approximately ½ of the outer hose diameter to the other parts is recommended. The distance should not be less than 10 to 15 mm.

• When replacing hoses and lines on movable parts (such as boom to stick), check before initial use, that there is not chafed area over the entire area of movement.

Danger!

Repair work on the wheels, e.g. removing tires from the rim or installing tires on the rim may only be carried out by expert personnel using the appropriate assembly tool.

If the tire inflator is operated incorrectly or carelessly, the following dangers can arise, leading to severe injury or even death: – Tires exploding due to over inflation.

– Lock ring bursting out.

Tires which have become flat may not be inflated. They must be repaired at a professional shop.

An incorrectly seated lock ring could burst off. Danger of injury.

When inflating the tires, use a tire inflator hose of a sufficient length with a self retaining hose valve.

When inflating the tires, stand outside of the danger zone.

Do not use different tire sizes.

5.3.1

Checking the tire pressure The air pressure in the tires has a considerable influence on the overall operational behavior of the machine. For this reason, the tire pressure should be checked regularly and corrected if necessary.

When working on the tires, ensure that the machine is positioned safely and is secured with wedges to prevent it from rolling off.

Ensure that the correct nominal tire pressure values, corresponding to the mounted tire and the machine group, are available for the tires.

Take the nominal values from the chart below.

Attach measuring equipment and correct air pressure, if necessary.

Oil change intervals for the turbocharged engine

Oil change intervals for Diesel engine depend on the following criteria: – First oil and filter change at 500 operating hours when using initial fill oil of quality E3-96.

– Additional filter changes every 500 operating hours.

– Additional oil changes dependent on climate zone, sulphur content in fuel and oil quality (see Tab. 5-6).

– If the stated operating hours are not reached within one year, then the engine oil and oil filter should be changed at least once a year.

5.5.2

Fuel Diesel fuels should meet the minimum requirements of the below listed, approved fuel specifications.

The sulphur content should not exceed 0.5 % . A higher sulphur content will affect the oil change intervals and the engine life.

5.5.2.1

Lubricity Decreasing sulphur content has raised the problem of Diesel fuel lubricity. It has been shown that Diesel fuels containing the maximum permitted European sulphur limit of 0.05 % can cause wear in the fuel injection system (particularly for distributortype injection pumps).

‘Brand’ fuels in Germany contain lubrication additives in their additive package. The fuel lubricity must be < 400 µm according to the HFFR (60°) test.

Suppliers should supply the additives as the responsible party for the fuel quality. It is not recommended that customers add secondary lubricity additives.

5.5.2.2

Flow improvement by adding petrol (regular gasoline) When ambient temperatures are below approx. 0 °C, the flow properties of summer Diesel fuels can become insufficient due to paraffin separation.

The same also occurs in winter Diesel fuels used in temperatures below -15 °C. Frequently, Diesel fuels with additives with a use temperature of up to -20 °C are offered.

To avoid malfunctions, Diesel fuel must be mixed with normal gasoline or petroleum at lower temperatures.

Adding normal gasoline should be viewed as an emergency remedy and must not exceed 30 % by volume.

Super petrol (Super or premium gasoline) may not be used for mixing. Engine performance can be reduced depending on the additives mixed in for cold weather conditions. For this reason, additions to the mixture should be kept as low as possible by taking the current ambient temperatures into account.

Danger!

For safety reasons, mix fuel only in the fuel tank.

Note!

When refuelling, the specifically lighter additional fuel should be added before the Diesel fuel. Then run the engine until the mixed fuel is distributed through the entire fuel system.

Warm-up guidelines At temperatures up to 10 °C below the given limit (black bar), the following warm-up guidelines apply: After starting the engine, regulate the Diesel engine only to approx. 1 / 2 of the rated speed. Operate the hydraulic cylinder and motors, move cylinder briefly against the stop. Warm-up duration approx. 10 minutes.

At even lower temperatures: Preheat the oil tank before starting the engine.

5.5.3.2

Environmentally friendly hydraulic fluids Note!

Mixing environmentally friendly hydraulic oils made by different manufacturers as well as mixing them with mineral oils must be avoided.

The environmentally friendly hydraulic oils recommended by LIEBHERR are limited to oils with a synthetic ester basis with a viscosity according to ISO VG 46.

The initial oil fill is carried out at the factory according to an approved list. Use of an environmentally friendly hydraulic oil must first be coordinated with LIEBHERR. Plant-based oils are not to be used due to their insufficient temperature properties.

The use of bypass filters is required.

5.5.3.3

Hydraulic oil monitoring Note!

Environmentally friendly hydraulic fluids should generally be checked at regular intervals through an oil analysis.

Oil analysis is recommended for mineral oils.

Machines in normal use: at least every 500 operating hours Machines in dust intensive use: at least every 250 operating hours LIEBHERR recommends that oil analyses be carried out by the WEAR CHECK Company and that oil changes are performed on the basis of the lab report (see also customer service and product information).

Notes on reducing hydraulicoil contamination in heavy dust use If the machine is generally operated with the hydraulic hammer, or if it is used under similar circumstances (heavy dust occurrence), there is the risk that the hydraulic oil will become contaminated more than usual.

To prevent early wear of hydraulic components, the oil change intervals (and intervals between oil samples) should be reduced and the following regulations should also be observed: – The filter cartridge(s) in the return filter must be replaced every 500 operating hours.

– For the return filter, 10 µm filter cartridges must be used instead of the usual 20 / 5 µm filter cartridges.

– The breather filter on the hydraulic tank must be replaced with a 2 µm fine filter (fineness of standard filter is 7 µm).

5.16.3.1

Cleaning LIKUFIX The LIKUFIX hydraulic coupling system is mostly maintenance-free.

We recommend to clean the system at regular intervals and spray it with lubricant (see Service manual). This will prevent dirt adhering and icing up.

If the system is kept properly clean, the seals are very durable.

Maintenance Parking and swing gear brake

Use a screwdriver to push down the seal plate on the coupler plug and lift out the defective seal ring with a pointed object (B).

Press the new seal ring together and place it on the seal plate with open side down (C).

Press down the washer as far as the groove, place the screwdriver in the middle of the seal ring and move your hand away (D).

Allow the seal ring to snap into the groove (E).

Remove the screwdriver (F).

The seal plate must move upwards. If necessary, press the seal ring down again until the seal plate is moveable.

5.17 Parking and swing gear brake Both the parking brake on the transmission and the swing gear brake are negative acting, wet multi-disk brakes.

They are vented hydraulically and are fully sealed and integrated in the transmission or swing gear.

Their usage purely as parking brakes makes them wear-free and therefore maintenance free.

5.18 General Maintenance points 5.18.1

Replacing wear parts In addition to the normal maintenance and service work, which have to be carried out in the given intervals, the following repairs can also be made by the machine operator or maintenance personnel: – Replacing worn teeth on the digging tool.

– Replacing defective sealing material on the pipe and hose system and on connections of hydraulic components (but not on pressure relief valves which are sealed with a lead seal at the factory).

– In addition, high pressure hoses, hydraulic lines and fittings on the hydraulic system can be replaced.

It should be noted that only original LIEBHERR spare parts are to be used.

This is particularly true for hoses and hydraulic lines, which must be preassembled at the factory. For all other repairs, particularly when removing the counterweight, factory or dealer mechanics must be consulted.

Operating instructions

General Maintenance points

With heavily worn teeth, considerably greater force will be required for the digging tool to penetrate the digging material. The teeth must be replaced in time to prevent damage to the tooth adapter.

Do not work with the machine if teeth on the digging tool are missing or are heavily worn.

To attach and remove teeth with wedge retainers:

Fig. 5-57

Replacing the teeth

Use a hammer and driver 1 to knock out the wedge 2 (A ).

Remove the old tooth.

Place a new rubber wedge retainer 3 on the tooth retainer (B).

Push the new tooth on the adapter.

Use the hammer to knock in the wedge 2 (C).

To attach and remove teeth with tension pin retainer:

Use a hammer and driver 1 to knock out the tension pin 2 (A).

Remove the old tooth.

Push the new tooth onto the adapter (B).

Knock in the tension pin 2 with the hammer (C).

5.18.3

Welding work on the machine Welding work on all main components serving for power transmission (such as the undercarriage frame, swing platform, attachment parts etc.) may only be carried out by the manufacturer or by an authorized workshop.

Operating instructions

Maintenance Inspection and maintenance plan

Disconnect the battery before starting any electric arc welding work on the machine.

Always disconnect the negative terminal (-) first and reconnect it last.

Turn the battery master switch off!

Caution!

If high currents flow through the bearings or sealing elements, they could be burnt.

Move the grounding cable of the welding tool as close as possible to the welding area, so that the welding current cannot flow over parts, such as the swing ring, joints, bearings, bushings, rubber elements or seals.

5.19 Inspection and maintenance plan Caution!

Careful maintenance can only be carried out when the machine is clean. In particular, visual checks such as crack testing are only possible on a clean machine.

Clean the machine before you start maintenance work (see also the chapter “Safe maintenance of the machine”, sub-headings “Cleaning” and “Crack testing”).

Note!

The daily maintenance work carried out by the equipment operator comprises a functional check of the brakes (slewing gear brake, service brake and parking brake), steering and the electrical and hydraulic systems.

In addition, a daily inspection must be performed to check for leaks from the engine, hydraulic system, transmission and axles.
