General Information Safety guidelines

When working on high voltage carrying components or sections, turn off the power supply, then connect the supply cable to the ground wire and use the grounding rod to ground these parts, such as condensers, etc.

Check the disconnected parts first to see if they are really voltage free, ground them and then short circuit them. Insulate neighboring voltage carrying parts.

12.Safety guidelines to be observed when welding on the machine Disconnect the battery first, when working on the electrical system or before any arc welding on the machine.

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

- In addition, before any welding, always unplug the plugs on the electronic boxes.

13.Safety guidelines to be observed when working on the attachment Never work underneath the attachment unless it is placed on the ground or properly supported.

When replacing or changing any part of the attachment, such as blade, cutting edges, teeth, ...) never use metal on metal support.

Never try to lift heavy parts. Always select and use appropriate lifting devices with sufficient lifting capacity.

When handling wire ropes, always wear gloves!

Do not disconnect any lines or hoses or remove fittings, caps or covers before the attachment has been placed down and the engine has been turned off. To release pressures -with the ignition key in contact position -move all servo controls (joystick and pedals) in both directions to release the servo pressure and any pressure remaining in the hydraulic circuit, then release the tank pressure by turning the bleeder screw.

After completion of all maintenance and repairs, make sure that all lines and hoses and fittings are properly connected and retightened.

Removing and installing the steel pins with a hammer can be very dangerous. Metal chips can cause injury.

15.Safe maintenance of hydraulic hoses and lines Hydraulic hoses and lines may never be repaired!

All hoses, lines and fittings must be checked regularly, but at least once a year for leaks and any externally visible damage! Any damaged sections must be replaced immediately! Escaping oil can cause injuries and fire.

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

Improper storage, mechanical damage and improper use are the most frequent causes of hose failures.

The service life of a hose may not exceed six years, including a storage period of no more than two years (always check the manufacturing date on the hoses).

Using hoses and lines close to the limit ranges of permitted use can shorten the service life (for example at high temperatures, frequent working cycles, extremely high impulse frequencies, multi-shift or around the clock operation).

Hoses and lines must be replaced if any of the following points are found during an inspection: Criteria: - Damage on the external layer into the inner layer (such as chafing, cuts and rips ); - Brittle outer layers (crack formation of the hose material); - Changes in shape, which differ from the natural shape of the hose or line, when under pressure or when not under pressure, or in bends or curves, such as separation of layers, blisters or bubble formation; - Leaks; - Non-observance of installation requirements; - Damage or deformation of hose fittings, which might reduce the strength of the fitting or the connection between the hose and the fitting; - Any movement of the hose away from the fitting; - Corrosion on the fittings, which might reduce the function or the strength of the fitting; - Storage or service life has been exceeded.

When replacing hoses or lines, use only Original replacement parts.

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

16.Roll over protection (ROPS) and falling object protection (FOPS) These are protective devices, which are integrated in the operator's cab. To reduce a weakening of the roll over or falling object protection, always check with your LIEBHERR dealer or Service Department before making any changes.

- Do not attach fire extinguishers, first aid kits, floodlights or similar objects to these protective structures.

- Welding points or drilling of holes could weaken the structure.

For similar work, always consult with your LIEBHERR dealer.

Any changes, which have not been explicitly approved by LIEBHERR would invalidate the roll over or falling object protection permit.

- Damage to the structure can also be caused by a roll over accident or falling objects, etc.

17.Attachments and installations Attachments and installations from other sources or parts which have not been approved by LIEBHERR for installation may not be installed on the machine without prior written permission by LIEBHERR. The necessary technical documentation must be forwarded to LIEBHERR.

18.Protection from vibration The vibration exposure on mobile construction machinery is generally the result of the way they are used.

Especially the following parameters have a significant influence: - Environmental conditions Unevenness and potholes; - Operating techniques: speed, steering, brakes, control of operating elements of the machine while driving as well as when working.

The machine operator himself affects the actual vibration exposure to a great degree himself, since he selects the speed, the gear ratio, the working mode and the travel route. This results in a wide range of various vibration exposure for the same type of machine.

The full body vibration exposure for the machine operator can be reduced if the following recommendations are observed: Select the correct machine, attachment parts and auxiliary equipment for the current task.

Use a machine, which is equipped with a suitable seat (i.e. for earth moving machinery, for example for a hydraulic excavator, a seat which meets EN ISO 7096).

Keep the seat in good order and adjust it as follows: - The adjustment of the seat and its suspension should be matched to the weight and size of the operator.

- Check the suspension and the adjustment mechanism of the seat regularly and make sure that these properties of the seat still correspond to the specifications of 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 as well as move and load the working attachments of the machine abruptly.

Match the machine speed to the travel route, to reduce vibration exposure: - Decrease the speed when driving on pathless terrain.

- Drive around obstacles and avoid very impassable terrain.

Keep the properties of the terrain, where your machine works and drives in good condition: - Remove large rocks and obstacles.

- Fill furrows and holes.

- Have machines available to establish and keep suitable terrain conditions and leave enough time to do this.

Drive longer distances (for example on public roads) with suitable (medium) speed.

For machines, which are predominately used for driving, use special auxiliary systems (if available), which make it possible to reduce vibration exposure for this type of application. If such auxiliary systems are not available, regulate the speed, to avoid “build up� of the machine.

Service Items Notes for the disposition of service fluids and filter: Service fluids may not be discharged into the ground, drainage system or waterways.

Different service fluids and filters should be collected and disposed of in separate containers.

Do not use containers, which previously held food items or drinks - to prevent danger of mix-ups.

Dispose of these items in an environmentally friendly manner according to applicable guidelines and regulations. Observe all state, local and national regulations.

Do not use old or incorrectly stored service fluids and filters, dispose of them properly.

1. Service fluids for Diesel engines with turbo chargers 1.1. Engine lube oil Engine lube oils must meet a certain quality and a certain viscosity, depending on their use and ambient temperatures. Problem-free operation can only be ensured only if the requirements for both areas are met.

1.1.1 Oil quality To meet the technical demands, only highly alloyed lube oils are used in modern Diesel engines. They consists of high-quality base oils, mixed with additives. These additives provide the required properties for these oils.

For LIEBHERR Diesel engines with turbo chargers, oils of the following specifications are approved, the higher quality oils are preferred: API - classification (American Petroleum Institute)

: CF-4, CG-4, CH-4, CI-4,

ACEA (CCMC) - classification : E2 (D4), E3 (D5), E4, E5 (Association des Constructeurs EuropÊens de l´Automobile) Note:

For older machines / Diesel engines, if still in use, engine oils according to the lower specification as noted in the original operation manuals may be used. However, we recommend the use of these new oils, since the service life of the engine can be extended significantly by using these higher quality oils. The originally noted oil and filter change intervals may be extended.

1.1.2 Oil viscosity Z In addition to the quality, the oil must also provide a certain viscosity the selection is made according to the SAE - classification (Society of Automotive Engineers).

The determining factor for the correct selection of the SAE classification is the ambient temperature. In most regions, SAE 10W-40 is recommended (see chart below).

If the viscosity is too high, starting problems can occur, if it is too low, the lubrication efficiency can be endangered, both factors can lead to increased engine wear.

The temperature ranges shown in the following chart are guidelines and may be exceeded or fallen below for a short time.

For the operation in extreme climate zones, such as in arctic regions, special guidelines apply and are available from the manufacturer.

1.1.3 Oil change intervals The oil change intervals noted in the Maintenance and Inspection schedules always apply to "normal operating conditions". They apply for normal, central European temperatures, annual operation of approx.

1000 operating hours, use of oils of the required minimum quality and fuels with a sulfur content of less than 0.5%.

When using higher quality oils, the operating hours per interval may be doubled - see the following chart.

However, the 500 hour interval may not be exceeded.

Engine oil and filters must be changed at least once a year, even if the given change interval has not yet been reached.

In difficult circumstances, such as repeated cold start, higher sulfur content (above 05.%) in the fuel, more severe climatic conditions (for example continuous temperatures below -10°C) etc., the intervals must be cut in half. This means, for each difficulty, the permitted operating hours per interval must be multiplied by a factor of 0.5.

Permissible oil change intervals in operating hours: Oil quality: Applications Ambient temperature

1.2. Diesel fuels Diesel fuels must meet the minimum requirements of the following specifications.

The sulfur content may not exceed 0.5%. A higher sulfur content has negative effects on oil change intervals and engine service life. A higher sulfur content above 1% is not permitted.

Fuels with low sulfur content (for example, according to European regulations <0.05 %) must contain additives to retain the lubrication efficiency according to HFRR(60°)-Test <400 m - . Insufficient lubrication causes premature wear of the injection system components, especially distributor injection pumps. The additives should be added by the fuel supplier, as he is responsible for the quality of the fuel. We do not recommend addition of secondary lubrication additives by the user.

Approved fuel specifications: DIN EN 590 + HFRR(60°)-Test <400 m ASTM D 975 - 89a 1D and 2D + HFRR(60°)-Test <400 m + cetane rating >45 (recommendation: >50)

Diesel fuels in very low temperatures At ambient temperatures below freezing (0 C), the flow properties of warm temperature Diesel fuel can become insufficient due to paraffin excretion. The same applies to cold temperature Diesel fuels in temperatures below. -15 C. In order to prevent operating problems in even lower temperatures, Diesel fuel with an additive is sometimes available, for use in temperatures to -20 C. In order to prevent operating problems in even lower temperatures, mix Diesel fuel with normal gasoline or petroleum. Addition of normal gasoline is a makeshift measure and may not exceed 30% per volume. Do not use Super gasoline for mixing.

Mixing fuel can diminish engine performance, for that reason, keep the added fuel as low as possible, depending on the ambient temperatures.

For safety reasons, mix fuel only in the fuel tank. When refueling, add the lighter additive before the Diesel fuel.

Then let the engine run for a short time until the mixture has been distributed throughout the fuel system.

Coolant filters are used on some engine series, which filter the coolant in the auxiliary flow and in addition, a chemical additive in the filter (DCA 4) reinforces the protection against cavitation, corrosion, scale deposits and foam formation. The DCA4 concentration must be between 0.3 and 0.8 units per liter of coolant. See the following chapter Coolant with DCA4 . This results in a mixing ration of approx. 48.5 % water, 48.5 % anti corrosion /antifreeze fluid and 3 % DCA4.

Check the mixing ratio regularly during maintenance work. See instructions in section 3.4.

If coolant must be replaced, make sure that the given mixing ratios are retained. Do not fall below this ratios nor exceed it.

Due to the natural aging process of the coolant, it must be replaced at least once every 2 years. Use only suitable coolant, free of contaminants. Clean contaminated cooling systems. Note the following regulations.

To replace or add coolant in larger quantities, mix the given parts outside the cooling circuit in a suitable, clean container first.

Fresh water guidelines: To mix coolant fluid, use clean, clear water, which is not too hard. Often, but not always, regular tap water may be used.

No. 10 005 347 1.3.2 Coolant - special filling - with anti corrosion fluids, without antifreeze fluids In exceptional cases and if ambient temperatures are constantly above the freezing point, for example in tropical regional, where no anticorrosion / antifreeze fluids is proofed available, fresh water and watersoluble anticorrosion fluids (Inhibitors) may be used as coolant.

Do not use coolant refiners (anticorrosion oils) with emulsifying capacity. If necessary, flush the cooling system before refilling.

The fresh water quality must meet use with DCA4 - see chart Â&#x201D;Approved fresh water qualityÂ&#x201D;.

The coolant must be changed once a year.

Use of DCA4 To provide sufficient protection against corrosion, approximately twice the amount of DCA4 must be used as compared to the above mixing ration, when using anticorrosion / antifreeze fluids and DCA4 - see above "overview chart and filter requirements".

The DCA4 concentration must be between 0.6 and 1.06 units. It must be checked during maintenance work or when the coolant filter is changed, and corrected, as necessary.

This results in a mixing ratio of max. 94 % fresh water and min. 6 % DCA4 additive Use of products from Caltex / Chevron Texaco / Havoline / Total To provide sufficient protection against corrosion with these products, a mixture of 92,5 vol.% coolant and 7,5 vol.% anti corrosion fluid must be kept.

The mixture ratio must be checked during maintenance work and corrected, as necessary. The concentration of the anti corrosion fluid must not fall below 5 vol.% nor exceed 10 vol.%.

2. Oil for hydraulic system In the hydraulic system, use only Diesel engine lube oils or special approved oils.

2.1. Oil quality 2.1.1 Approved engine oil classifications API - classification (American Petroleum Institute)

: CF-4, CG-4, CH-4, CI-4,

ACEA (CCMC) - classification : E2 (D4), E3 (D5), E4, E5, (Association des Constructeurs Européens de l´Automobile) Note:

The API classifications CC, CD, CE and CF are now obsolete, however, in quality, they had been approved for use in the hydraulic system.

2.1.2 Special oils Approval is given for each machine type separately. Special guidelines are issued with the release.

The following product presently considered to be an environmentally friendly hydraulic fluid: Panolin - HLP Synth - VG 46 2.2. Oil viscosity In addition to the quality, the oil must also provide a certain viscosity, the selection is made according to the SAE classification (Society of Automotive Engineers).

The determining factor for the correct selection of SAE classification is the ambient temperature, single grade oils are preferred.

If the viscosity is too high, it can cause cavitations, if it is too low, the lubrication efficiency may be endangered.

Both can cause failure of hydraulic components.

The temperature ranges shown in the following chart are guidelines. When operating the machine within the black temperature range, the following warm up procedure should be carried out.

Single grade oils

Multi grade oils

Viscosity for environmentally friendly hydraulic fluids according to ISO: VG 46 (covers SAE 10W and SAE 20W-20 or SAE 10W-30) For operation in extreme climate zones, such as arctic regions, special guidelines are available from the manufacturer.

Warm up procedure: a) In temperatures up to 10° C below the given limit (black range) After starting, run the Diesel engine at medium speed. Warm up the hydraulic system by carefully actuating the hydraulic cylinders. Extend and retract the hydraulic cylinders fully for short periods. After 5 minutes, carefully engage the travel hydraulic as well. Total warm up period is approximately 10 minutes. b) At even lower temperatures: Before starting the Diesel engine, preheat the oil in the hydraulic tank, then proceed as described in paragraph a).

Gear oil The lube oil specification for gears is based on API and SAE classification. The oil chamber in travel gears for double lifetime seal is filled with oil from the hydraulic system - see section 2.

2.1. Oil quality As a general rule, only oils meeting API - classification GL-5 may be used.

2.2. Oil viscosity The following oils must be used in travel gears, and are highly recommended for use in splitter boxes: Viscosity classification SAE 85 W - 140 EP For splitter boxes, oils of

Viscosity classification SAE 90 EP or SAE 80 W - 90 EP may also be used.

For the operation in extreme climatic conditions, such as in arctic regions or in extreme temperatures ranges, such as in slag applications, special oils may be approved if the prevailing ambient temperatures are known operations.

2.3. Lube oil for final drive - sealing chamber For oil quality and viscosity see section 2, Oil for hydraulic system, but do not use special oils.

3. Lube oil for support shaft bearing For oil quality and viscosity see section 2, Oil for hydraulic system, but do not use special oils.

4. Hoist gear oil - pipe layers As a general rule, the guidelines noted in the Operation and Maintenance manual and the winch manufacturer should be observed.

For lubrication technical reasons, we recommend the use of Diesel lube oil, which meets at least one of the following quality and viscosity classifications.

4.1. Oil quality according to

API - classification

: CF, CF-4, CG-4, CH-4, CI-4,

General Information Tightening Torques

The preload and tightening torques listed in the chart are from VDI guidelines 2230 of July 1986.

Installation preload FM and tightening torques MA for shaft screws with metric standard or fine thread per DIN ISO 262 and DIN ISO 965 T2 (replacement for DIN 13 part 13) and screw head dimension of hex head screws with shaft DIN EN 24014 (replacement for DIN 931 part 1) or socket head screws DIN EN ISO 4762 (replacement for DIN 912).

The chart values are valid for lubricated screws, surface black treated, phosphated or galvanic zinc plated and for dry screws, surface according to flZn - LH-Norm 10021432 (replaces DACROMET 500) Medium friction

= 0,12.

G

Always observe the tightening torques and/ or procedures listed in drawings / parts lists, instructions of component descriptions, if noted, they override the factory standards listed in the torque charts.

Never use a standard lock washer with 10.9 or 12.9 screws. If a washer is necessary, use only "heavy duty" washers, made from hardened material.

Always use torque wrenches with the correct range - the upper third of the range should include the listed torque value according to the chart.

When using impact screws, make sure that the given tightening torque is observed - should be checked before and during the tightening procedure with torque wrench (Nm x 0,7375 = ft.lbs.)!

General Conservation guidelines

1.5.00 Conservation guidelines 1

General All parts of a construction machine are exposed to corrosion, especially when the machine is taken out of service. Corrosion can be compared to wear. However, the effects of corrosion can greatly exceed that of mechanical wear and shorten the service life of the affected parts significantly. For that reason, for longer shut down, the machines and its components must be preserved according to certain guidelines.

In general, these guidelines are tiered according to the following times: Taking the machine out of service â&#x20AC;&#x201C; for an unknown duration Shut down of the machine Shut down for up to 2 months Shut down for up to 12 months Shut down for longer than 12 months Return to operation The required measures are graduated depending on the different time frames. The conservation measures cannot be strictly standardized and they must be shorted or lengthened depending on the assessment of necessity (such as environmental influences).

Such influences are, for example: Placement location of machine (for example in unprotected surrounding, in closed areas, protected by a roof, temperate surrounding) Type of climate (for example extreme temperatures, location in water / near the coast, etc.)

Note!

For conservation for sea transport, special guidelines must be observed, which are not included in these instructions. Refer to the special operating instructions.

2

Taking the machine out of service â&#x20AC;&#x201C; for an unknown duration If a machine is taken out of service for a longer period of time without conservation, then it must be operated in intervals not to exceed 14 days, to prevent abnormal corrosion and its effects.

Before putting the machine back into service, check all oil levels and correct them, if necessary.

Always carry out the specified daily maintenance work before putting the machine back into service. In addition, carry out the time limited maintenance work according to the inspection schedule and additional Diesel engine Operating instructions no later than the specified intervals.

Put the machine into operation according to the Operating instructions and operate it until the Diesel engine and the hydraulic system has reached the specified operating temperature in the hydraulic tank and in the coolant circuit.

Actuate all functions of the travel, working hydraulic as well as functions of additionally installed hydraulic components and alternately operate them over a period of approx. 20 minutes. The hydraulic cylinders must be extended and retracted over their full stroke length.

When turning the machine off, retract all hydraulic cylinders fully, if possible, and fill the fuel tank. If the machine is parked on soft ground, park the machine on wooden planks or similar and secure it to prevent it from rolling off.

Check the batteries and remove them and recharge them, if necessary. Check the electrical contact points and grease them, if necessary.

Shut down of the machine Preparations for shut down Park the machine on horizontal, dry and solid ground and secure it to prevent it from rolling off. Lower the working attachment to the ground level so that there is no longer any residual pressure of the hydraulic.

Clean the machine diligently according to the procedure outlined in the Operating instructions.

The machine must be completely dry before starting the conservation measures. Dry electronic components and damp areas on the machine with pressurized air.

If freezing temperatures are expected for the intended duration of shut down, then the fuel tank must be filled with winter fuel. Then start the Diesel engine and let it run for some time to bring the winter fuel into the fuel circuit. Then add enough fuel to the fuel tank until it is full.

Note!

When a conserved machine is moved for loading or transport, then the conservation protection on the piston rods of the cylinders will most often be removed by the scraper ring.

For that reason, if the machine is transported, the conservation of the piston rods must be rechecked after loading and carried out again, if necessary.

Note!

Despite completed conservations measures, the machine must still be inspected in certain intervals and touched up, if necessary. This is within left to the discretion of the operator, but these inspections should be carried out regularly (monthly), especially in aggravated conditions (cold, heat, near the coast, etc.).

Special Tools, Application Guidelines Repair welding

Repair welding Before starting any welding work on PR Series 4 machines, various electronic parts and components must be unplugged to prevent damage to the machine.

Note!

See operating instructions: Preparations for maintenance In addition, for arc welding, the ground terminal of the welding unit should be connected in the immediate vicinity of the blank work piece, which is to be welded.

1. Preparation of a crack The crack must be free of paint, grease and dirt.

To prevent the crack from extending during the preparation or the welding process, the end of the cracks should be drilled with a hole of at least 0.32" (8mm) in diameter.

The crack should now be ground, chiseled, torch cut or arced out at a 60° angle. Be certain the edges are clean and extend through the full cross section of the material, without exceeding the 0.04" (1 mm) space in the lower part. On larger grooves, a welding safety should be installed.

Certain materials must be preheated to 300°F (150°C) prior to welding.

Special preparations are necessary when preparing a crack in manganese steel. Due to its hardness, mechanical preparation, such as a chisel or hobbing machine is not possible. We suggest that the crack is prepared with a slow running and water cooled grinding wheel to prevent overheating.

Other possibilities for preparing cracks or removing high alloy welding seams are the use of cutting electrodes of the type UTP 82 AS. 2. Preparation of a weld The area to be welded must be free of paint, grease, oil, moisture and dirt. During rain, the area to be welded must be covered. Materials with a thickness above 0.60" (15 mm), high carbon steel or steel which is difficult to weld, the material must be preheated to approximately 176°- 392°F (80°- 200°C).

Pre-heating is also necessary when the ambient or component temperature is below 40°F (5°C) or when the construction of the component prevent the welding stress to be released.

3. Storing Electrodes Use only dry and undamaged electrodes. Electrodes which are rusty or damaged should not be used. Electrodes should be stored in a dry room with a minimum temperature of 59°F (15°C). Open packages should be carefully closed and stored after the welding work is completed.

4. Welding Technique The welding of material with the necessary electrodes (see table under paragraph 7) is in accordance with DIN 1912.

The adjustment of the welding machine - dictated by the different thicknesses of the electrodes - can be taken from the table of the electrode package.

Beginning with a material thickness of 1/4" (8 mm), butt welds must be made in several layers. The weld is applied in several beads. Wide butt welds are filled with several side by side beads, with the last layer covering the center. The electrode should melt evenly without creating burrs and peaks. The valley or crater, which is created when changing electrodes must be filled in and overlapped with the next electrode. To prevent cracks in those craters, care must betaken that they are properly filled.

If the crack extends towards the outer edge of the material, slag may be trapped or burn holes may be created.

To prevent this, the following aid may be used: Tack a piece of sheet metal to the outer edge of the material. The welding seam begins now at the sheet metal in the direction of the arrow. After the welding is completed, the sheet metal is removed and the edge of the material is ground smooth.

The weld must cool off slowly and should therefore be protected from rain and wind.

5. Reinforcement of the welding seam If the crack of the material is due to an overload or abuse, a reinforcement plate should be welded over the crack. The selection of the correct reinforcement plate is based on the construction and load factors of the component to be repaired.

For this reason, only general recommendations can be made as to the size and shape of the reinforcement plates.

6. General application of reinforcement plates 6.1. Shape of reinforcement plates The crossover or connection between the reinforced and not reinforced part should be as gradual as possible.

This means that the size of the plate should be selected in such a way that new or unacceptable high stress in the repaired parts are avoided. Plates with sharp corners (such as a rectangular plate) should not be used.

Suitable reinforcement plate with high tensile strength.

Suitable reinforcement plate against bending and alternating loads.

Special Tools, Application Guidelines Repair welding

6.2. Plate Thickness The thickness of the reinforcement plate should be up to 2/3 (66%) of the thickness of the material to be reinforced.

6.3. Plate Quality The yield and tensile strength of the reinforcement plate should be equal to the material to be reinforced.

6.4. Plate Installation The welded area of the crack should be ground so it is smooth and level.

The size of the plate must be selected in such a way that the longer sides of the plate extend into the connecting construction of the material to be reinforced. The plate should also overlap the crack on each side by at least 1" (20 mm). The correct position and fit of the reinforcement plate is achieved through clamping and spot welding.

6.5. Plate Welding The reinforcement plate should be welded on by running a welding bead alternately on both sides. The welding should always start in the middle of the plate and run towards the outside. Be certain to observe that each welding seam has proper run out.

Direction of weld

Direction of weld

The size of the welding run "a" is figured out in reference to the thickness "k" of the reinforcement plate.

Use formula: a=0,5 k Up to a welding run "a" of approx. 1/8" (3 mm) a single run can be made, however, as a general rule, a double run should be preferred.

Above a welding run "a" of 1/8"(3 mm), the first run provides excellent penetration between the reinforcement plate and the basic material. Subsequent runs are added on top of the first run.

After the welding is completed, clean the welding seam as necessary. Grind the run out between reinforcement plate and basic material.

7. Selecting the correct electrodes For repair welding, only lime based {Kb} electrodes should be used, and as a rule, the electrodes {additional material} should be "softer" than the basic material. Exceptions to this rule should be observed.

Important:

To reach the theoretical welding quality, the work must not only be performed in a professional manner, the electrode manufacturer's guidelines must absolutely be observed as well.

Welding of vertical-down welds on steel components is not permissible!

Note!

On Series 4 machines, due to design reasons, only seals toward the outside are used.

2. Installation 2.1. General installation notes The slip rings of the seals are made as a pair. For that reason, they may only be used in the original pairing, in new as well as in used condition.

Avoid shock and impact, since this could damage the sealing surfaces of the hard cast duo cone slip rings.

Round off any sharp edges on the sealing mounts.

Slip rings seals and their mounts must be absolutely clean and free of grease at installation.

O-rings may not be lubricated with oil.

Slip ring seals should generally be installed with the aid of an installation device, see section 2.1 Special tools.

Caution!

Without the aid of the installation device, the O-ring can roll up on the conical slip ring surface.

If the pressure at installation is one-sided, the seal half can incline and/ or the O-ring can twist.

These improper installations as well as damage to the sealing surfaces cause leaks.

Technical Data - Maintenance Guidelines Maintenance and inspection guidelines

Maintenance and inspection guidelines 1. General guidelines 1.1. Documentation for work to be carried out For work to be performed, refer to the Maintenance and inspection schedule for your particular machine model see section 3.2.

Check off completed inspections or work by making a check mark on a copy of the form and have the completed form countersigned.

The determined test values for the adjustment checks should be documented on an adjustment check list corresponding to the machine model, see paragraph 3.5.

In addition, confirm the performance of the inspection / delivery in the machine s inspection booklet and send the appropriate Service ticket to the appropriate LIEBHERR company. After removing the old sticker, attach the new inspection sticker, which can also be found in the inspection booklet, clearly visible in the cab.

Explain the set up and the contents of the machine documentation to the machine operator. Special emphasis should be given to safety regulations and maintenance task to be performed between inspections.

1.2. Safety guidelines During all maintenance, inspection or repair work, the applicable safety guidelines according to section 1.2. and the operating instructions for the machine must be observed. In addition, all applicable Federal, state and local safety requirements, accident prevention regulations and local laws must be observed.

1.3. Intervals The given Maintenance and inspection intervals may not be exceeded, if necessary, they should be shorted, for example: Changing filters, draining condensation and sediments in case of dirty fuel; cleaning the radiator in case of contamination; changing filters and oils during or after repairs, etc.

1.4. Taking oil samples 1.5. Taking oil samples Any required oil samples must be taken directly from the component before the oil is changed. Run the machine to distribute the oil before taking the oil sample to evenly distribute any existing particle concentration evenly and to prevent incorrect test results due to deposits. To determine the initial situation after repairs (residual contamination), take another sample shortly after reuse.

Take the sample from the center area of the oil volume with a manual suction pump, do not overfill the sample container, replace the suction hose every time a sample is taken.

Fill out accompanying paperwork correctly and completely. Wrong information can result in unnecessary service or can lead to omissions of necessary service or repair, resulting in unnecessary high costs.

Also refer to documentation in the oil analysis kits.

1.6. Oils, filter and other If possible, oils should be drained when warm . Any work which must be done when the machine is cold , for example adjusting the Diesel engine valves, should be completed before.

Oil filters should be changed after the oil has been drained and before the oil is refilled.

Before reusing the machine, bleed the systems as necessary. Turn the starter about 10-15 seconds before starting the Diesel engine.

If possible, cut removed filter cartridges and elements open to check for abnormal deposits. The type and amount of deposits can be helpful to draw conclusions about the condition of the system or the start of any problems.

Dispose of old oils, filters and other throw away items properly!

Maintenance and inspection guidelines

For all maintenance, inspection and repair work, use only Original LIEBHERR replacement parts or maintenance items. If the customer insists on the installation of other will fit parts, inform the customer about a possible loss of warranty, and make a note to this effect on the inspection report.

For general screw tightening torques, see page 1.4., for tightening guidelines for track pad and sprocket segment screws, see page 12.1.

2. Performance guidelines 2.1. Inspection work on the Diesel engine

2.1.1 Change the lube oil filter Loosen filter cartridges with a filter wrench and remove by hand. For installation position, see Operating and maintenance instructions.

The standing filters can also be loosened with a suitable tool via the studs on the cartridges. The filters remain filled due to leak safe guards!

Tighten the filter cartridges only hand tight (30 Nm).

2.1.2 Check the radiator cap and fan Radiator cap Check the seal and function of the pressure relief valve. If necessary, replace the cap.

Note: If the pressure in the cooling system is too low, steam bubbles formation is increased, which can cause engine problems.

Check the fan for damage and make sure the distance to the cooler hood is even. If necessary, realign the hood.

2.1.3 Check / replace the coolant antifreeze / corrosion inhibitor Cooling systems without coolant filter Check the required part of antifreeze or corrosion inhibitor with an optical charge tester see Special tools, page 2.1. The testing procedure is independent of the coolant temperature.

The display is shown by a line between light and dark on the right scale of the sight gauge.

When using corrosion inhibitor / antifreeze fluid, the temperature is shown to which freeze protection is provided (minus values above the 0°C - mark, nominal value at least -37°C). For details, follow the directions of the manufacturer.

If in exceptional cases only corrosion inhibitor is used (special fill), then the ratio can be read on the same scale. In this case, the display corresponds to each -1°C of 1% of corrosion inhibitor (nominal value = 1%).

Replace coolant with antifreeze every 2 years. Replace special fill coolant every year. To drain the coolant from the cooler and engine block, refer to the machine s operating instructions.

See also section 1.3. - Service fluids, chapter 1.3- Coolant.

If required, check the coolant pump before refilling see paragraph 2.1.

2.1.4 Check / replace the coolant antifreeze protection and DCA4 part cooling systems with coolant filter Before replacing the coolant filter, check the DCA4 concentration, watch for possible gel formation.

The test must be made with DCA4-Test kit CC2602M see Special tools, section 2.1. Included in the kit is a test instruction with maintenance guidelines in several languages, which must be strictly observed. Note the expiration date of the test kit = "Use before" for example "Jun. 2005".

In case of gel formation, the coolant must be drained and the system must be cleaned. Before preparing the refill, check the quality / specification of water and antifreeze. The antifreeze fluids may not be outdated nor precipitate silicates.

Note: To prepare the coolant, mix water first with DCA4 in the required ration. Then add the required antifreeze fluid to the water / DCA4 mixture and mix well.

Replace the coolant with antifreeze and DCA4 every 2 years. Replace the special coolant fill annually. To drain the coolant from cooler and engine block, refer to machine s operating instructions.

See also section 1.3. Service fluids, chapter 1.3 - coolant.

If required, check the coolant pump before refilling see paragraph 2.1.

2.1.5 Check the V-belt condition and tension Check by hand, see Operating instructions .

Check with Krikit test kit, see Special tools, page 2.1.

Replace worn or brittle V-belts.

For procedure to adjust or change the belt, see Operating instructions .

2.1.6 Check oil, coolant and fuel system as well as Intake and exhaust system Check systems for leaks, damage and chafing. Fix leaks properly, retighten loose mountings and hose clamps. Replace chafed hoses or lines, make sure they are routed properly to prevent kinks and chafing.

2.1.11 Check the flame glow system replace oil separator check / adjust fuel injectors check water pump A defective flame glow system greatly influences the starting behavior of the Diesel engine. For that reason, make sure to check the system before the start of the cold season.

Due to age or external damage, the membrane of the oil separator can leak, which can cause engine damage due to dust ingestion. For that reason, make sure to check the service date and replace old or damaged oil separators.

If there is a drop in engine performance, if the engine runs unevenly or a knocking sound can be heard coming from the engine, or if exhaust fumes are dark, check and adjust the fuel injectors ( nozzles ).

If noted for inspection, remove the cover to the coolant pump and check the axial play of the pump shaft with a test gauge. If the axial play is

0,1 mm, replace the coolant pump.

For details, see "Service Manual Diesel engines .

2.2. Inspection / maintenance work on the hydraulic system 2.2.1 Clean the magnetic rod On new machines and after repairs, check and clean the magnetic rod daily until only minute deposits are found. After that, use normal maintenance intervals. Increasing deposits point to abnormal wear.

2.2.2 Check / replace return filter inserts Replace the main return filter insert in the hydraulic tank.

Check the strainer inserts on variable displacement pumps and motors and check the regulating pump s replenishing circuit filter for deposits.

If any deposits are found, determine the origin and find the cause. If necessary, repair the component or replace it. Replace the strainer insert.

2.2.3 Check the working and travel hydraulic system for function and leaks, hose routing for chafing, mountings and fittings for tight seating Run through all travel and working movements and check for abnormal function.
