The Operation and Maintenance Manual contains important information on how to operate the machine safely, properly and with maximum efficiency. Observing these instructions helps to prevent hazardous situations, to reduce repair costs and downtimes and to increase the reliability and service life of the machine.

The Operation and Maintenance Manual must be supplemented by the respective national rules and regulations for accident prevention and environmental protection.

The Operation and Maintenance Manual must always be available in the driver's cab of the machine.

The Operation and Maintenance Manual must be read and put into practice by any person in charge of carrying out work with or on the machine, such as 

operation, including setting-up, troubleshooting in the course of work, care, evacuation of production waste and disposal of fuels and consumables,



maintenance (inspection, servicing, repair) and / or



transport.

In addition to the Operation and Maintenance Manual and the mandatory rules and regulations for accident prevention and environmental protection in the user's country and at the place where the machine is to be used, the generally recognized technical rules for safe and proper working must 1 be observed .

The Operation and Maintenance Manual is directed to the mining-machine specialist. It cannot provide basic know-how. This can be acquired, for example, in several days' instruction by a qualified Caterpillar Global Mining HMS GmbH mechanic or by attending an CGM HMS training course for operators or maintenance personnel.

The CGM HMS after-sales service will be pleased to deal with any queries you may have after reading through the operating instructions.

All CGM HMS Operation and Maintenance Manuals are issued in German and then translated.

Even a good translation may give rise to questions which CGM HMS will be pleased to answer.

The operating instructions are not work instructions for carrying out major repairs. Such work is willingly done for you by the CGM HMS after-sales service.

Further machine documentation The documentation relating to the machine is listed according to scope, quantity and language in the shipping note of the machine or in the covering letter if supplied separately. The operating instructions, the spare-parts list and the Technical Handbooks are marked with the serial number of the machine.

The documentation supplied with your machine is rather comprehensive. Therefore, it has been split up in several volumes: Volume 1: the present Operation and Maintenance Manual, Volume 2:

spare-parts catalog of the machine,

Volume 3:

cross reference list of spare-parts,

Volume 4:

electrical circuit diagram and key,

Volume 5:

OPERATING INSTRUCTIONS 6050 / 6050FS Introduction WARRANTY The warranty of Bucyrus HEX presupposes among other things that the servicing works as described in the operating instructions have been performed:

Do not operate the machine  when components / assemblies are defective or missing,



by the Bucyrus HEX Service



in a workshop authorized in writing by Bucyrus HEX,

In cases of doubt seek advice from the Bucyrus HEX Service.

or  and 

by using the original spare parts of Bucyrus HEX.

The proper execution of the servicing works must be documented on the Bucyrus HEX Service checklists.

if one or several of such components of which more than one are installed in the machine have been removed.

Bucyrus HEX refuses to assume the guarantee for damage and consequential damage caused by an abusive utilization of the machine.

Therefore: Do not operate the machine,  when several track rollers or support rollers have been removed; 

when one or several slewing gearboxes have failed or been removed;



when one or several teeth on the backhoe or on the shovel are worn or missing;



when parts of the hardfacing layer on the backhoe or on the shovel are worn or missing.

Working under these circumstances results in heavy wear and possibly in severe damage and thus in high repair costs.

Such circumstances are considered by Bucyrus HEX as "abusive utilization".

Why? The machines have been designed and built on the basis of detailed calculations and so that all of the components installed absorb the occurring forces and are thus loaded to an equal extent.

Example: If the machine is used for working with, for instance, one or even several track rollers removed, the forces must be absorbed by the remaining track rollers. These are then overloaded or loaded to a greater extent than calculated.

The consequences are higher wear and consequential damage to the track rollers, but also to other components of the machine: chassis, travel gearbox and crawler track.

OPERATING INSTRUCTIONS 6050 / 6050FS Operation Undercarriage

Stored Program Control (SPC)

The undercarriage of the hydraulic excavator serves as a stable base and for travelling. The crawler tracks are driven hydraulically with oil motors and travel gearboxes. Undercarriage and superstructure are connected by means of a swing ring.

The SPC controls the functions 

Engine Start,



Engine Stop,



Engine Idle,



Central lubricating system,

Superstructure



Further auxiliary functions.

The superstructure accommodates the drive and part of the hydraulic and electrical equipment.

Further information is given in the technical manual: Stored-program control.

Drive

Central Management System (CMS)

The drive unit comprises diesel engines, pump transfer gearboxes, hydraulic pumps, hydraulic cylinders and hydraulic motors.

Hydraulic system All working and travelling movements are performed hydraulically. The movements are controlled by servovalves. The working commands are initiated by hand and transmitted to the valves via control circuits. The oil supply from the superstructure to the undercarriage is ensured by the rotor.

The hydraulic system is overload-protected by pressure-relief valves. The hydraulic pumps are supplied with oil from a hydraulic reservoir.

The CMS is an electrohydraulic servocontrol. Together with the PMS, it provides for optimum interaction between drive hydraulic circuit and working movements.

The required working movements are recognized by microcontroller-assisted scanning of the operating elements (hand levers, pedals) and transmitted to electrohydraulic valves.

In the system sequence, the drive regulation is first activated to provide hydraulic working energy. Only then are working movements enabled.

Further information is given in the Technical Handbook, chapter “Electric, Electronic”.

Pump Managing System (PMS) The Pump Managing System (PMS) with overlimit regulation ensures optimum utilization of the installed or preset engine power. The electronic pump demand control prevents the machine from demanding more hydraulic power than the diesel engines can furnish. A microprocessor ensures that the hydraulic output power of the pump is optimally suited to the actual operation conditions.

The PMS box (load-limit regulator) is installed in a control cabinet in the driver's cab.

2-8

BA RH200(3 847 006.00)-EN

OPERATING INSTRUCTIONS 6050 / 6050FS Operation Demand control / Zero-flow regulation In the fine-control range, swivelling of the hydraulic pumps, and thus the variation of oil flow, are proportional to control lever and pedal valve travel. This means that during the work, the pumps supply only as much hydraulic oil as required to perform the working movement. In the neutral position of the control levers, the pumps are automatically swivelled to zeroflow.

These special features offer the following advantages: 

reduced fuel consumption



minimum power losses



reduced temperature of the hydraulic oil



greater service life of hydraulic pumps and diesel engines.

Board-Control-System (BCS) The BCS is a data-evaluating and data-processing system whose function is to collect, evaluate and store data about the excavator's operating status and to display these to the operator.

The BCS is based on a micro-processor. The measured values (actual values) supplied by sensors and transducers installed in the excavator are compared to preset nominal values. Out-of-limit conditions are displayed in the form of error messages in the cab.

Critical operating conditions are additionally indicated by optical and acoustic warning signals.

Further dedails are set out in the “Operating Instructions Board-Control-System”.

Electrical system The electrical system operates on 24 volts.

Automatic engine speed reduction If the control pedals and control levers and thus the servovalves are not actuated for a period of 10 seconds or more (programable), the speed of the engines is automatically reduced to idling. Thisfunction is a further contribution to fuel economy.

OPERATING INSTRUCTIONS 6050 / 6050FS Operation MAXIMUM MACHINE INCLINATIONS, INFORMATION

The working performance of the machine is especially economical when the machine stands on firm and level ground.

The machine must not exceed the inclinations indicated for working, travelling and servicing operations and during downtimes. The values specified in the tables below (next page) are valid for all types of working equipment.

A loss of performance and higher wear must be accepted when the machine works in an inclined position, e.g. when building a ramp or when slewing uphill.

If the maximum inclinations are exceeded, there is a risk of severe damage to the engines due to insufficient lubrication. In the event of extreme inclinations the machine can topple over.

For the building of ramps, the values specified in the table "Maximum inclinations during working operations" may be exceeded. In this case, however, a reduced service life of the components can be expected.

During downtimes, the machine must be parked in such a way that its inclination does not exceed 3° / 5.2 %.

Maximum machine inclinations during working operations:

OPERATING INSTRUCTIONS 6050 / 6050FS Operation Emergency machine drive Moving the excavator after failure of the hydraulics The weight of the excavator, the resistance of the crawler tracks and the high reduction in the travel gearboxes make towing or pushing of the excavator in the event of a failure or of defects in the hydraulic system impossible.

Required equipment 

a self-propelled machine with a dual-circuit hydraulic system max. working pressure: 380 bars / 5511 psi min. working pressure: 220 bars / 3191 psi pump discharge rate: 150 l/min / 39.6 gal/min

These are minimum values. The pump discharge rate indicated corresponds to an excavator travelling speed of ca. 3 m/min (10 ft/min). 

4 high-pressure hoses ca. 11 m (36 ft) long; DN 40 1 ½“ SAE Connection at one end; ready for connection to the auxiliary machine at the other.



4 plugs (high-pressure type) for 6000 PSI 1 ½“ SAE connections.

Fig. 2-108:

The excavator can therefore only be moved with the help of another machine (Fig. 2-108:) (wheel loader or grader). The machine used as auxiliary machine must be equipped with a dual-circuit hydraulic system.

Track parking brake

The excavator is equipped with four superstructure holding brakes integrated in the swing gearboxes.

The superstructure holding brakes are used to block the superstructure and the undercarriage.

The excavator is equipped with four track brakes integrated in the track drives.

The superstructure holding brakes are parking brakes.

Switch the parking brakes on by means of switch (82, Fig. 2-110:): 

when the excavator is parked,



when travelling over longer distances.

The track brakes are parking brakes which relieve the hydro-static travel drives during working operation and which protect the excavator against rolling forwards and backwards.

The brakes are controlled by means of the travel pedals (112 and 113, Fig. 2-111:). In neutral position of the pedals, the brakes are applied and the excavator is braked. During travelling, the brakes are released.

The track brakes can also be activated with switch (72, Fig. 2-110:).

Depending on switch position, the brakes are permanently engaged or are automatically applied after ca. 8 sec. each time the excavator stops.

With this switch position, the brakes are released as soon as the "Travel" function is activated.

Inspect the site for underground gas, power and water lines before starting work. Any damage to such lines is a risk to life!

Clean off any earth, mud, snow, ice, grease and oil adhering to your working footwear before operating the machine. There is otherwise a risk of slipping off the pedals and initiating inadvertent movements.

Sound the horn to warn persons in the immediate vicinity before starting work.

Stop work if anyone is in the hazard range of the machine. Make sure they have left the hazard range before resuming work.

Never operate the machine unless it is standing on a reasonably horizontal, flat surface. The stability of the machine is otherwise at risk.

Ensure that the attachment has adequate clearance below overhead power lines and structures.

Trenches and working faces may give way. Keep well clear of them.

Do not operate the machine, 

when several track rollers or support rollers have been removed;



when one or several slewing gearboxes have failed or been removed;



when one or several teeth on the backhoe or on the shovel are worn or missing;



when parts of the hardfacing layer on the backhoe or on the shovel are worn or missing.

Running-in instructions for hydraulic cylinders Compression of an oil/air compound in a hydraulic cylinder may result in detonations which might damage pistons and sealing rings.

Prior to initial commissioning and/or after repairs, run in the hydraulic cylinders as follows:  Start up the engines and run at low speed.

The pressure-limiting valve in the hydraulic system must not respond  In the first two working cycles, retract and extend the pistons of the hydraulic cylinders to max. ½ to ¾ (not to the limit stop).

Never change direction suddenly. The waiting time between changes of direction must be at least 4 seconds.  In the next eight working cycles, retract and extend the pistons of the hydraulic cylinders to the limit stop. The waiting time between changes of direction must be at least 4 seconds.  When all hydraulic cylinders have been run in, the excavator can operate at a higher engine speed.

Warming-up-phase for the hydraulic system At low temperatures, bring the engines down to moderate speed, then activate all hydraulic functions for about 10 minutes (bring to service temperature). For further instructions, see section "Lubricants".

If the BCS indicates problems with the cooling liquid temperature, engine oil pressure, coolant level, alternator or hydraulic oil filter control (with hydraulic oil at service temperature) light up: Lower the working equipment and shut off engines.

Working under these circumstances results in heavy wear and possibly in severe damage and thus in high repair costs.

Such circumstances are considered by Bucyrus HEX as "abusive utilization".

Bucyrus HEX refuses to assume the guarantee for damage and consequential damage caused by an abusive utilization of the machine.

Securing the working equipment

Personel

Stand working equipment on the ground in such a way that no movements can be made if mechanical or hydraulic connections become detached.

Assembly work may be carried out only by operating or maintenance personnel who have the necessary know-how at their disposal.

If such know-how is lacking, meticulous instruction must be given by experienced personnel, e.g. from Bucyrus HEX. The operating manual, and in particular the section headed "Fundamental Safety Instructions", must have been read and understood.

Only such persons may start up the machine during assembly work in order to adjust the attachments.

Incorrect operation of the machine or the attachments may give rise to life-threatening situations.

Personal protective gear and working clothes Wear closely fitting working clothing when working on the machine. Loose, wide garments may catch on machine parts and result in injury.

Wear a safety helmet, safety footwear and gloves.

Tools and auxiliaries Tools, hoists, slings, trestles and other devices must be in a reliable, safe state.

Metal splinters may cause injury when accessory bolts are being driven in or out. A brass or copper mandrel should therefore be used for this purpose, and goggles must be worn.

Secure any equipment or component which is to be mounted or dismantled, or whose position is to be changed, with hoists or appropriate slinging/supporting devices to prevent them from moving, slipping or falling inadvertently.

Securing the machine Carry out work on the attachment only if the machine is secured as described in the "Securing the machine" section.

Selecting the attachments The machine can be equipped with various attachments. The components of the attachments are assembled with hydraulic cylinders and connectors. Components can be combined in various ways for optimum adaptation of the attachments to the specific application.

Operate the machine only with the equipment and component combinations expressly approved by Bucyrus HEX for this type of machine.

Never install and commission other equipment and component combinations without Bucyrus HEX first having inspected and approved the project in writing.

Protective roof against falling objects The machine is equipped with an integrated cabprotection roof (FOPS).

Even when a machine is parked on a horizontal surface with ist attachments supported on the ground and its driving motors switched off, there may still be substantial residual pressure in parts of the hydraulic system, e.g. primary pressure from the last hydraulic movements prior to stopping the machine.

Water used for extinguishing purposes would vapourize instantaneously on contact with burning substances and spread burning oil, for example, over a wide area. Water generates short circuits in the electrical system, possibly producing hazards.

Notify the fire brigade.

Fastening and securing elements Check fastening and securing elements, e.g. bolts, nuts, washers, before using them again.

Replace any damaged parts.

Escaping oil is an environmental hazard.

Residual pressure is reduced only gradually. If an intervention into the hydraulic system is to be undertaken immediately after stopping, the system must be depressurzized: (do not leave the driver's seat)  Stand working equipment on the ground,  Shut off the engines,

Spare parts Use only the original sparts parts of Bucyrus HEX.

 Move all control levers and pedals repeatedly into all ndirections.

They are the only ones to fulfill the technical specifications of the machine.

Handling oils and greases

Screwed connections, piping, hydraulic hoses

Hot lubricant or hydraulic oil emerging uncontrolled from the system may result in severe burns.

Repair any leakage in the piping and hose system immediately.

Never set foot withing reach of the emerging oil jet.

A fine, highly pressurized jet of hydraulic oil can penetrate the skin.

Avoid contact with the skin. Wear gloves and firm protective clothing.

Used oil may be harmful to the skin.

Clean soiled skin thoroughly with warm soapy water and apply a barrier cream. Never use fuels or solvents for cleaning the skin.

If you have swallowed any oil, avoid vomiting but consult a doctor immediately.

Never search for leakages with the fingers, but use a piece of cardboard and always wear goggles.

If oil has penetrated into the skin, consult a doctor immediately.

Never repair damaged piping; always replace them.

Replace hydraulic hoses immediately on detecting any damage or moist areas.

Tighten leaking screw plugs only when the system is depressurized.

Escaping oil is an environmental hazard.

Do not dispose of these substances together with household wastes.

Never process spares containing asbestos mechanically. Inhaling asbestos dust is a health hazard.

Fill these substances into the containers provided for such purposes.

Clean sealing faces prior to assembly.

Like any other oil, also bio-degradable, "environmental-friendly" hydraulic oil must be disposed of separately.

Engine exhaust gases

Do not allow oils and oily wastes to penetrate into the soil or into water. They are an environmental hazard.

Used pressure vessels for cold-starting fluid (ether) must be disposed of properly. Contact the supplier with regard to disposal / return of the vessels.

Even apparently empty pressure vessels can contain rests of ether and therefore explode if they are damaged or heated up above 49°C / 120°F. They must therefore be handled in the same way as full pressure vessels.  Do not keep them on the machine. 

Do not damage or open the vessels.



Do not expose the vessels to great heat or direct sunlight.



Do not dispose of in fire.



Keep the vessels in a place inaccessible to unauthorized persons.



Dispose of the vessels properly.

BA RH200(3 847 006.00)-EN

Start and operate combustion engines only on well-ventilated premises.

OPERATING INSTRUCTIONS 6050 / 6050FS Inspection and servicing Handling batteries

Handling of cold-starting fluid (ether)

Battery Posts, terminals and related accessories contain lead and lead compounds, chemicals known to cause cancer and reproductive harm.

Wash hands after handling.

The engine compartment can be equipped with pressure vessels containing cold-starting fluid (ether).

Batteries give off explosive gases.

Never handle batteries close to naked flames and unshielded light sources, never smoke.

Battery acid is toxic and corrosive.

Avoid any contact with the skin, mouth, eyes and clothing. Avoid spilling battery acid or inhaling the vapours.

Wear gloves, firm protective clothing and goggles when handling batteries.

If the skin is splashed with acid, rinse thoroughly with running water and consult a doctor.

If the eyes are splashed with acid, rinse thoroughly with running water and consult a doctor immediately.

Never set tools down on the battery. They may induce a short circuit, causing irreparable damage to the battery and injuring persons.

Never wear metal necklaces, bracelets or watchstraps when working on the battery. The metal parts may induce a short-circuit resulting in burns.

Dispose of used batteries separately from other waste in the interests of environmental protection.

Before working on the electrical system Before performing work on the electrical system where tools, spare parts, etc. can come into contact with electrical conductors or contacts, the battery must be disconnected.

Disconnect first the negative and then the positive terminal.

Ether is toxic and highly flammable; the vessels are under pressure. These pressure vessels can explode if exposed to high temperatures (above 49°C / 120°F) or in the event of damage.

Protect the pressure vessels against damage before beginning to work in or close to the engine compartment.

Read and observe the instructions on the pressure vessels.

For further details please refer to the instructions and safety data-sheets of the manufacturer / supplier of pressure vessels with cold starting fluid (ether).

Provide for sufficient ventilation.

Do not eat, drink or smoke when replacing an empty vessel.

Do not inhale the vapours of escaping cold-starting fluid.

In contact with the skin, ether can cause frostbites and irritations. Avoid skin contact.

Wear suitable protective gloves and goggles.

Even apparently empty pressure vessels can still contain rests of ether and therefore explode if they are damaged or heated up above 49°C. They must therefore be handled in the same way as full pressure vessels.  Do not keep them on the machine. 

Do not damage or open the vessels.



Do not expose the vessels to great heat or direct sunlight.



Do not dispose of in fire.



Keep the vessels in a place inaccessible to unauthorized persons.



Dispose of the vessels properly.

After the work: Reconnect first the positive and then the negative terminal.

OPERATING INSTRUCTIONS 6050 / 6050FS Inspection and servicing Selecting oils and greases Use the recommended qualities only, matching viscosities with the temperature level.

After servicing To prevent corrosion, coat all bright metal parts with a grease film.

On completing work, re-install all protective devices.

Filters Replace / clean all filter elements or filter cartridges within the specified periods.

Never start up the drive motors while work is being done on the machine.

Carry out performance tests with the machine.

All filters are coordinated carefully with the equipment. Original Bucyrus HEX parts must be used to ensure smooth running and a long service life of the engine and the hydraulic units.

Sealing elements When dismantling parts, watch for sealing elements.

Check sealing elements prior to installation and replace any that are even slightly damaged.

When assembling, ensure a perfect fit.

Oil-level check and oil change Position the machine horizontally.

Change the oil when the machine is at operating temperature. Warm oil flows better and carries suspended particles (carbon or abraded matter) better.

Lubricating Clean the lubricating nipple, then lubricate as scheduled.

OPERATING INSTRUCTIONS 6050 / 6050FS Inspection and servicing INSPECTION AND SERVICING WORK, FIRE AND EXPLOSION HAZARD Safety instructions Prior to commencing work, obtain informationon the national and corporate rules for the prevention of accidents and avoiding fires.

Pay particular attention to hazards caused by combustible and easily flammable substances.

Obtain information on the safe handling of the fire extinguishers to be used.

Avoid smoking and open fire on, next to and below the excavator.

Place suitable fire guardings (fire barriers) if open fire or flying sparks cannot be avoided during repair work.

If necessary, also cover the ground with fireprotective blankets.

Apply special protection to cables, cable ducts as well as to hose and pipe lines.

Have all your welding, flame cutting and grinding work approved before starting work.

The engine compartment can be equipped with pressure vessels containing cold-starting fluid (ether). Ether is toxic and highly flammable; the vessels are under pressure. These pressure vessels can explode if exposed to high temperatures (above 49°C / 120°F) or in the event of damage.

Protect the pressure vessels against damage before beginning to work in or close to the engine compartment.

Ensure sufficient ventilation.

Even battery gases can ignite in open flames or fire.

Do not keep any fire extinguishers that are not suitable or have not been tested.

Combustible and easily or highly inflammable substances or liquids increase the risk of fire and explosion. This is also valid for pressure vessels containing flammable substances as, for instance, spray oil or cold-starting fluid (ether). They are heat-sensitive and can explode even if exposed only to intensive sunlight.

Do not extinguish flammable liquids with water.

Use:  dry-powder, carbon-dioxide or foam extinguishing compounds.

These substance can also ignite themselves if they come close to hot units or objects as, for instance, a turbocharger.

Do not store these substances on the excavator. If combustible, easily or highly flammable substances or liquids were used during maintenance operations, they must be completely removed from the excavator at the end of the work.

When getting into contact with burning substances, the fire-fighting water would abruptly evaporate and distribute the substance such as oil over a wide area. Water causes short-circuits in the electrical system thus possibly entailing new hazards.

Call the fire brigade.

Clean the excavator carefully after the maintenance, if oil, grease, fuel, detergents or coldstarting fluid have been spilt over the machine. If possible, use a steam-jet cleaner for cleaning.

Avoid parking the excavator in places where  combustible substances such as coal dust or tar are present. 

open or smouldering fire may occur.

Remove the excavator from such an area where combustible or easily flammable liquids have spilled from the excavator onto the ground.

Flying sparks (caused by welding, flame cutting, grinding, electrical short-circuit) may cause fire on the ground that can spread to the excavator.

OPERATING INSTRUCTIONS 6050 / 6050FS Inspection and servicing LUBRICANTS

Avoid mixing of different hydraulic fluids

Notes on the selection of oils and greases

The machine has been run in at the factory with BM Long Term Hydraulic Fluid HSS (Part-No. 2482971). Bucyrus HEX recommends using this high-grade hydraulic fluid also in operation as it has been made especially for use in these machines to which it is also perfectly adapted.

Original Bucyrus HEX oils and greases Besides regular and careful maintenance, the quality of the oils and greases used in the machine has a decisive influence on high performance, reliability and long service life of a machine and of its units and assemblies.

The lubricants tables in the Bucyrus HEX Operating Instructions contain specifications for the oils and greases that are approved for use in Bucyrus HEX machines. These oils and greases are especially adapted to Bucyrus HEX machines and their units and assemblies.

Other oils and greases which do not fulfil the requirements of the specifications can be the cause of premature wear or of damage to and failures of machine units and assemblies.

For this reason, Bucyrus HEX only approves the use of the specified oils and greases.

All other qualities are not approved.

Alternative oils and greases The oils and greases filled into the machine must meet at least the specifications mentioned in the lubricants tables of the Bucyrus HEX Operating Instructions.

In the event of damage to the machine or to its units and assemblies caused by the use of alternative oils and greases that are not compatible with Bucyrus HEX specifications, Bucyrus HEX does not assume any responsibility and does not accept any warranty claims.

If oil analyses are performed regularly and with positive results, the BM Long Term Hydraulic Fluid can remain in the machine for up to 10 000 operating hours.

If an alternative hydraulic fluid is to be used, it must fulfil the same specifications. Please note that the change interval for alternative fluids is fixed at 5 000 operating hours.

There is an increased risk of damage to hydraulic components, if different hydraulic fluids are mixed during topping up as well as when changing over to a fluid of a different type or from another manufacturer.

For topping up, it is therefore necessary to use only same hydraulic fluid as the one that is already in the hydraulic system.

When changing over to an alternative hydraulic fluid, please observe that there is always a small amount of old fluid remaining in the hydraulic system even after the system has been emptied. The mixing of this residual amount of old fluid with the new alternative fluid reduces the properties of the fluid dramatically and can cause damage to components of the hydraulic system in operation.

To avoid this result, the change-over to the alternative fluid must be performed in strict compliance with the manufacturer's prescriptions. The manufacturer must confirm that his hydraulic fluid is compatible with the BM Long Term Hydraulic Fluid.

The remaining amount of old fluid must not exceed 2% of the total volume. This can only be achieved by repeated flushing with the total fluid volume.

If the remaining amount of fluid exceeds 2% of the total volume, the fluid becomes a detrimental "mixed fluid".

The operation of the system with mixed fluids must by all means be avoided.

Bucyrus HEX assumes no warranty for damage caused as a result of the machine having been operated with consumables of inappropriate specification or with mixed fluids.

The engines, the hydraulic oil reservoir, the pump transfer gearboxes, the swing gearboxes and the radiators (engine cooling liquid) are moreover equipped with automatic drain valves (1, Fig. 3-11:).

These automatic drain valves permit oil- and cooling-liquid changes without polluting the environment.

Carry out oil changes when the machine is at operating temperature; warm oil drains away more easily.

Filling and draining is can be done by means of a hose through the service station (tanklift) (Fig. 3-10:).

For filling and draining, a flexible hose is connected to the express coupling on the service station and to the service vehicle at the other end.

The filling operations require an overpressure, whereas the draining operations require low pressure.

Fig. 3-11:

Change oil or cooling liquid as follows:  Place a collecting recipient for used oil or cooling liquid under the corresponding automatic drain valve. For the recipient capacity refer to the "Refilling quantities - Oil" table or to the "Refilling quantities - Other" table.  Unscrew protective cap from automatic drain valve.  Screw on hose line (2) to open the valve, so that the oil or the cooling liquid can flow out.

Fig. 3-10:

 When the oil or the cooling liquid has drained away, unscrew hose line to allow the valve to close automatically.  Screw protective cap back in place.

OPERATING INSTRUCTIONS 6050 / 6050FS Inspection and servicing Cold-starting fluid (ether) - Replacing the pressure vessel

If the machine is used in low temperatures, the engine may be equipped with a cold-starting device.

Read and observe: "Inspection and servicing Safety instructions"

The pressure vessel containing the cold-starting fluid (ether) can be installed in or near the engine compartment.

Risk of injury Cold-starting fluid is composed mainly of ether.

Ether is toxic when the mists and vapours are inhaled. Ether is harmful to the eyes, the skin, the respiratory system and the central nervous system.

Prolonged inhalation of ether can be fatal.

In contact with the skin, ether can cause frostbites and irritations.

Ether is toxic and highly flammable; the vessels are under pressure.

These pressure vessels can explode if exposed to high temperatures (above 49°C/ / 120°F) or in the event of damage.

Before replacing an empty pressure vessel: Read and observe the instructions on the pressure vessels.

Replacing the pressure vessel:  Remove the clamp around the pressure vessel.  Unscrew the pressure vessel carefully from the metering valve.  Remove the used seal from the metering valve.  Insert a new seal into the valve (supplied with the new pressure vessel).  Screw the new pressure vessel onto the metering valve and tighten by hand.  Fasten the clamp round the pressure vessel.

For further details please refer to the instructions and safety data-sheets of the manufacturer / supplier of pressure vessels with cold starting fluid (ether).

Even apparently empty pressure vessels can contain rests of ether and therefore explode if they are damaged or heated up above 49°C / 120°F. They must therefore be handled in the same way as full pressure vessels.  Do not keep them on the machine.

Provide for sufficient ventilation of the surroundings.



Do not damage or open the vessels.



Do not expose the vessels to great heat or direct sunlight.

Do not eat, drink or smoke when replacing an empty vessel.

3-150

The vessel is screwed onto an electro-mechanical metering valve. At temperatures below 0°C (32°F), this valve is activated automatically by the engine electronics and injects a precisely metered amount of cold-starting fluid into the air intake duct of the engine.



Do not dispose of in fire.

Do not inhale the vapours of escaping cold-starting fluid (ether).



Keep the vessels in a place unaccessible to unauthorized persons.

Avoid skin contact. Wear suitable protective gloves and goggles.



Dispose of the vessels properly.

Do not fill in cold cooling liquid when the engine is at operating temperature.

Before refilling, allow engine to cool down to below 50° C (122°F).

For topping up of the cooling system use specially prepared water only.

Specially prepared water must consist of:  calcium-free water, distilled water, rain water, and 

anti-freeze compound.

The anti-freeze compound must always be filled into the system independent of climatic conditions.

In this case, it serves as corrosion protection for the cooler made of aluminum.

The mixing ratio of anti-freeze compound / cooling water must be at least 50 % : 50 % (anti-freeze protection down to -40 °C / -40°F).

For use at lower temperatures, the amount of antifreeze must be increased accordingly.

After filling in cooling liquid allow the engines to run for short period to eliminate air voids before topping up with cooling liquid until the cooling liquid level lies between the “FULL” and the “LOW” mark of the level indicator (4, Fig. 3-33:).

In case of significant cooling-liquid losses, the whole cooling system must be checked for leaks.

if the projector housing is opened in an inapropriate way or



by sticking one's hand into an opened or damaged projector.

Protect yourself from potential risks by reading and by observing the following safety instructions.

Always switch off the projector and disconnect it from its power supply before replacing the Xenon lamp.

Allow the xenon lamp to cool off before removing it from the projector.

Wear googles and safety gloves when replacing the lamp.

Never stick your hand into the lampholder. The contacts may still be live with residual voltage.

Never switch on the projector when the xenon lamp has been removed.

There is a risk of voltage discharge and damage to the lampholder.

The glass body of the xenon lamp is filled with different gases and metal gases and is under gauge pressure (risk of injury from splinters) If the xenon lamp breaks apart in closed room (workshop), all persons must leave the room and the room must be ventilated for at least 20 minutes to exclude any health risks caused by gases.

Further instructions Always hold the xenon lamp by the base. Never touch the glass bulb. Sweat and grease from the skin would evaporate when the lamp is in operation and obscure the reflector.

If the fingers have nevertheless come into contact with the glass bulb, the fingerprints must be removed with a clean cloth and some alcohol.

The replaced Xenon lamp must be disposed of as special waste.

Never switch on projectors when housing or electrical wiring is damaged.

Have damaged projectors be replaced by a qualified electrician as soon as possible.

Before working on the hydraulic system, make sure that the system is without pressure and that the residual pressures have also been eliminated.

Shut off the engines.

Risk of burning caused by hot hydraulic components (e.g. hydraulic oil reservoir, cylinder, valves).

Depressurizing the hydraulic system Hydraulic systems may only be opened if they are completely depressurized. Even when an excavator is parked on a horizontal surface with the working equipment resting on the ground (Fig. 3-66: and Fig. 3-67:) and with its drive engines stationary, there may still be a considerable amount of residual pressure in parts of the hydraulic system, as e.g. the primary pressure resulting from the last hydraulic movements before the immobilization.

Residual pressures disappear only gradually. If work is to be carried out on the hydraulic system immediately after the immobilization, the system must be freed from pressure, i.e. depressurized:

Secure the machine as described in the "Securing the machine“ section.

Do not start up the drive engines when the hydraulic oil reservoir is empty. The hydraulic pumps may be destroyed if they are allowed to run dry.

Avoid mixing of different hydraulic fluids The machine has been run in at the factory with BM Long Term Hydraulic Fluid HSS (Part-No. 2482971). CGM HMS GmbH recommends using this high-grade hydraulic fluid also in operation as it has been made especially for use in these machines to which it is also perfectly adapted.

If oil analyses are performed regularly and with positive results, the BM Long Term Hydraulic Fluid can remain in the machine for up to 10 000 operating hours.

If an alternative hydraulic fluid is to be used, it must fulfil the same specifications. Please note that the change interval for alternative fluids is fixed at 5 000 operating hours.

There is an increased risk of damage to hydraulic components, if different hydraulic fluids are mixed during topping up as well as when changing over to a fluid of a different type or from another manufacturer.

For topping up, it is therefore necessary to use only same hydraulic fluid as the one that is already in the hydraulic system.

When changing over to an alternative hydraulic fluid, please observe that there is always a small amount of old fluid remaining in the hydraulic system even after the system has been emptied. The mixing of this residual amount of old fluid with the new alternative fluid reduces the properties of the fluid dramatically and can cause damage to components of the hydraulic system in operation.

To avoid this result, the change-over to the alternative fluid must be performed in strict compliance with the manufacturer's prescriptions. The manufacturer must confirm that his hydraulic fluid is compatible with the BM Long Term Hydraulic Fluid.

The remaining amount of old fluid must not exceed 2% of the total volume. This can only be achieved by repeated flushing with the total fluid volume.

If the remaining amount of fluid exceeds 2% of the total volume, the fluid becomes a detrimental "mixed fluid".

The operation of the system with mixed fluids must by all means be avoided.

CGM HMS GmbH assumes no warranty for damage caused as a result of the machine having been operated with consumables of inappropriate specification or with mixed fluids.

OPERATING INSTRUCTIONS 6050 / 6050FS Inspection and servicing Pressure-accumulator inspection regulations

Checking the gas charging pressure in the pressure accumulator

The following regulations are applicable only in Germany. Please observe the relevant regulations in force in your own country.

After commissioning (new installation or repair), the gas charging pressure in the pressure vessel must be checked at least once during the first week. If no pressure loss is detected, the second pressure test must be performed after ca. 3 months. If no pressure loss is detected in this test either, the testing interval can be fixed at once pressure test each year.

Extract from the German regulations The accumulator vessel must not be subjected to welding, soldering or any other mechanical work.

Work on systems containing accumulators (repairs, connection of pressure gauges or similar work) may be carried out only when the fluid pressure has been relieved.

Extract from the German acceptance regulations Hydraulic accumulators are pressure vessels and are therefore subject to the "Druckbehälterverordnung (DruckbehV)" [Pressure Vessel Regulations].

Their installation, equipment and operation are governed by the "Technische Regeln Druckbehälter (TRB)" [Technical Rules for Pressure Vessels]. The pressure vessels of hydraulic accumulators are classified by the admissible operating pressure p in bars, the capacity l in liters and the product of pressure and capacity p x l. Depending on the class to which the accumulator belongs, the following inspections are mandatory:

The above-mentioned pressure tests are required to ensure the functioning of the track tensioner.

They are no substitute for the inspections as required by the "Pressure Vessel Regulations".

Before checking the gas charging pressure (nitrogen filling pressure) in the pressure accumulator, the track must first be slackened, i.e. the hydraulic part of the tensioning system must be depressurized. See: "Function".

OPERATING INSTRUCTIONS 6050 / 6050FS Inspection and servicing Pressure-accumulator inspection regulations The following regulations are applicable only in Germany. Please observe the relevant regulations in force in your own country.

Extract from the German regulations

Checking the gas charging pressure in the pressure accumulator After commissioning (new installation or repair), the gas charging pressure in the pressure vessel must be checked at least once during the first week. If no pressure loss is detected, the second pressure test must be performed after ca. 3 months. If no pressure loss is detected in this test either, the testing interval can be fixed at once pressure test each year.

The accumulator vessel must not be subjected to welding, soldering or any other mechanical work.

Work on systems containing accumulators (repairs, connection of pressure gauges or similar work) may be carried out only when the fluid pressure has been relieved.

Extract from the German acceptance regulations Hydraulic accumulators are pressure vessels and are therefore subject to the "Druckbehälterverordnung (DruckbehV)" [Pressure Vessel Regulations].

Their installation, equipment and operation are governed by the "Technische Regeln Druckbehälter (TRB)" [Technical Rules for Pressure Vessels]. The pressure vessels of hydraulic accumulators are classified by the admissible operating pressure p in bars, the capacity l in liters and the product of pressure and capacity p x l. Depending on the class to which the accumulator belongs, the following inspections are mandatory: Group III p ≥ l bar and p·x l ≥ 200 bars p·x l ≤ 1000 bars

OPERATING INSTRUCTIONS 6050 / 6050FS Repair work REPAIR WORK, FIRE AND EXPLOSION HAZARD Safety instructions Prior to commencing work, obtain informationon the national and corporate rules for the prevention of accidents and avoiding fires.

Pay particular attention to hazards caused by combustible and easily flammable substances.

Obtain information on the safe handling of the fire extinguishers to be used.

Avoid smoking and open fire on, next to and below the excavator.

Even battery gases can ignite in open flames or fire.

Combustible and easily or highly inflammable substances or liquids increase the risk of fire and explosion. This is also valid for pressure vessels containing flammable substances as, for instance, spray oil or cold-starting fluid (ether). They are heat-sensitive and can explode even if exposed only to intensive sunlight.

These substance can also ignite themselves if they come close to hot units or objects as, for instance, a turbocharger.

Do not store these substances on the excavator. If combustible, easily or highly flammable substances or liquids were used during maintenance operations, they must be completely removed from the excavator at the end of the work.

Avoid parking the excavator in places where  combustible substances such as coal dust or tar are present. 

Place suitable fire guardings (fire barriers) if open fire or flying sparks cannot be avoided during repair work.

If necessary, also cover the ground with fireprotective blankets.

Apply special protection to cables, cable ducts as well as to hose and pipe lines.

Have all your welding, flame cutting and grinding work approved before starting work.

The engine compartment can be equipped with pressure vessels containing cold-starting fluid (ether). Ether is toxic and highly flammable; the vessels are under pressure. These pressure vessels can explode if exposed to high temperatures (above 49°C / 120°F) or in the event of damage.

Protect the pressure vessels against damage before beginning to work in or close to the engine compartment.

Ensure sufficient ventilation.

Do not keep any fire extinguishers that are not suitable or have not been tested.

Do not extinguish flammable liquids with water.

Use:  dry-powder, carbon-dioxide or foam extinguishing compounds.

When getting into contact with burning substances, the fire-fighting water would abruptly evaporate and distribute the substance such as oil over a wide area. Water causes short-circuits in the electrical system thus possibly entailing new hazards.

Call the fire brigade.

Clean the excavator carefully after the maintenance, if oil, grease, fuel, detergents or coldstarting fluid have been spilt over the machine. If possible, use a steam-jet cleaner for cleaning.

open or smouldering fire may occur.

Remove the excavator from such an area where combustible or easily flammable liquids have spilled from the excavator onto the ground.

Flying sparks (caused by welding, flame cutting, grinding, electrical short-circuit) may cause fire on the ground that can spread to the excavator.

Have the pressure accumulators removed from the machine, if safe protection cannot be ensured.

Slewing rings and articulated joints The welding current must not flow through ballbearing or roller-bearing slewings rings, through bolted connections or articulated joints or through hydraulic cylinders.

An electric current flowing through an air gap (e.g. in the bearing or in the articulation) produces a spark which damages the metallic surface.

The welding clamps must therefore always be connected very close to the weld area (max. 2 - 3 m away (6.6-9.8 ft)).

Information relating to the electrical system and to electronic modules Electric arc welding produces electromagnetic fields, electrostatic charges and voltage spikes which can cause damage to electronic modules.

Although the electronic modules of the machine are carefully protected against these influences, it is nevertheless necessary to take additional precautions in order to prevent such damage to the greatest possible extent.

•

Switch off the electrical system ("ignition OFF").

•

Open the battery main switch (or disconnect the starter batteries from the machine).

•

Lay the welding cables as far away from electric lines as possible.

If it is not possible to implement all of the abovementioned precautions, all connectors must be removed from the electronic modules before beginning any welding work.

•

Protect withdrawn terminals and connectors from short circuits and soiling. Cover up terminals and connectors with foils or adhesive tape.

•

Never touch the enclosures of electrical and electronic modules with the welding electrode.

•

Protect electric lines against the heat emanating from the weld area.

•

Restore all electrical connections when the welding operations are terminated.

Never connect the ground clamp of the welding cable to the enclosures of electric or electronic modules.

OPERATING INSTRUCTIONS 6050 / 6050FS Repair work Welding on the counterweight

Welding on the cab

Counterweights may contain a build-up of flammable gases. Before starting to work, counterweights must be flushed for at least 20 minutes with compressed air in order to remove these build-ups of gas. To permit flushing, the counterweight has two bores in its upper part: a threaded bore M18x1.5 for the compressed-air line and another unthreaded bore to let the air out.

The driver's cab is designed in such a way that it meets the FOPS (Falling Objects Protective Structure) requirements in accordance with DIN EN ISO 3449.

Detailed information / instructions on this subject can be found in Service Information 2006-33 which is available on the CGM HMS website under Maintenance & Service.

Welding on components of the working equipment and on other fully or partly closed steel structures Components may be equipped with pipelines routed inside. These lines can contain combustible substances such as hydraulic oil or lubricating grease which may be set on fire by welding operations.

•

Check whether pipes or hosepipes are connected to the steel component.

•

Depressurize these lines.

•

Open the screwed connections and empty the lines routed inside the component.

•

Start welding only after these operations have been carried out.

Welding and other mechanical work is forbidden as there is a risk of reducing the structural stability of the cab.

Further information More detailed information concerning the state-ofthe-art execution of welding operations can be found in the Service Manual "Welding for maintenance and repair".

For problems or queries please contact the competent service personnel.

If parts of the machine have to be removed or dismantled, please read and observe the chapters: "Assembly of working equipment, safety instructions", "Inspection and servicing, safety instructions", "Repair, safety instructions".

Electric lines may also be be laid inside partly open steel structures in order to protect them against damage. They are not always visible from each viewing direction. Electric lines may catch fire as a result of the heat produced during welding.

•

Therefore check carefully whether electric lines are laid in the vicinity of the weld area.

•

Protect electric lines against the heat produced at the weld area or have them removed before starting the welding operations.

OPERATING INSTRUCTIONS 6050 / 6050FS Repair work DISPOSAL AT THE END OF THE SERVICE LIFE Dismantling and removal instructions Before beginning work, think about the risks involved, e.g.: 



Most of the machine components have considerable mass. Therefore use only lifting gear and slings of sufficient bearing capacity.

Risk of residual pressures still in the hydraulic system. Be very careful when opening hydraulic lines.

Read the following text attentively and observe the instructions given. Respecting the instructions will help you to protect yourself against health hazards and injuries and to prevent avoidable environment pollution.

4-14

Risk of deflagrations In the course of time, flammable gases may have formed or accumulated in the hollow spaces of welded constructions, e.g. the counterweight. To remove these flammable gases, the hollow spaces must be purged carefully with compressed air before work with hand grinders, flame cutters or other sparking tools is being undertaken.

Risk of fire Remainders of fuel or oils may lead to the formation of flammable gases in tanks or other hollow spaces. When these tanks or hollow bodies are cut into pieces, the gases may ignite or even explode.

For this reason, remove all fuel or oil remainders from these components and purge them carefully with compressed air in order to eliminate flammable gases (other efficient methods of removing flammable gases can also be applied) before work with hand grinders, flame cutters or other sparking tools is being undertaken.

Fault

For this reason, it is vital to read through the relevant section of the operating instructions once again before rectifying any faults.

The fault is described here as the outcome of an observation or a previous activity.

Therefore make careful observations.

If you are unable to detect the cause of the fault or to rectify it, apply to the Bucyrus HEX after-sales service.

Study the problem carefully. First think, then act.

Describe the fault and all accompanying circumstances as precisely as possible when calling on the Bucyrus HEX after-sales service. Exact data allow for fast troubleshooting.



What repair and servicing work was carried out previously?



Has this defect already occurred?

Never do any jobs for which you are not qualified.



The fault table lists all faults which have been reported to date and outlines their possible causes and rectifying measures. In exceptional cases, a described fault may also have a different cause.

Is it one or several simultaneously occurring faults?

Possible causes

Ask yourself the following questions:  Which warning signals preceded the fault?

The possible causes of the observed fault are outlined in this group. They are arranged in order of probability, i.e. the possible cause occurring in most cases heads the list.

Measures This describes the troubleshooting procedure.

OPERATING INSTRUCTIONS 6050 / 6050FS Annex Engine electronic unit, displaying stored fault codes Engine electronics, displaying faults The CENTRY-system can display and record detectable fault conditions within the CENTRY system and circuits.

The fault lamps (43, Fig. 5-1:) for the left engine and (46, Fig. 5-2:) for the right engine will light up for approx. two seconds after switching on the electrical system of the machine using key switch (32). They will go out when no faults are being detected.

While a fault condition is being detected, the fault lamp will turn “ON“ or “ON FLASHING”.

CENTRY will turn the lamp „ON“ for warning faults, and „ON FLASHING“ for more severe faults that can affect engine operation and need immediate attention. Active fault conditions MUST be corrected as soon as possible.

Engine electronic, displaying faults in memory

Fig. 5-1:

To determine an active CENTRY fault code, the CENTRY system must be switched into diagnostic mode. To do so: •

Shut off engine.

•

Turn key switch electrical system (32) in position „ON“, don’t start the engine.

•

Push momentary switch „DIAGNOSTIC ON/OFF“ (55 or 65) for one or two seconds to the left.

If there are no active faults in the memory, fault lamps (43 or 46) will light up only while momentary switch (55 or 65) is pushed.

However, if an active fault does exist, the warning lamp will begin flashing out the three digit diagnostic code.

Example: Two flashes with short pause between = 2; Short pause; Three flashes with short pause between = 3; Short pause; Four flashes with short pause between = 4; Longer pause, then repeating the same code.

Fig. 5-2:

The fault code is = 234.

Pushing momentary switch (55 or 65) will advance to the next fault code.

In the „Operation and Maintenance Manual CENTRY-System“ you can find a table listing all the fault codes with information about reason and effect.

To quit the diagnostic mode, turn key switch electrical system (32) in position “OFF” or start the engine.
