OPERATING INSTRUCTIONS RH200 Electric Introduction PREFACE These operating instructions are designed to familiarize the operator with the machine and its designated use.

The operating instructions contain 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 operating instructions must be supplemented by the respective national rules and regulations for accident prevention and environmental protection.

The operating instructions must always be available in the driver's cab of the machine.

All Bucyrus HEX operating manuals are issued in German and then translated. Even a good translation may give rise to questions which Bucyrus HEX 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 your appropriate Bucyrus HEX dealer after-sales service.

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 and spare-parts list are marked with the serial number of the machine.

On taking receipt of the consignment, please check that the documentation is complete and in the language requested by you.

The operating instructions 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 operating instructions 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 be observed.

The operating instructions are directed to the mining-machine specialist. They cannot provide basic know-how. This can be acquired, for example, in several days' instruction by a qualified mechanic or by attending an Bucyrus HEX training course for operators or maintenance personnel.

Your appropriate Bucyrus HEX dealer after-sales service will be pleased to deal with any queries you may have after reading through the operating instructions.

OPERATING INSTRUCTIONS RH200 Electric 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 guaranteee 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 RH200 Electric Introduction ACCIDENT PREVENTION REGULATIONS FOR ELECTRICALLY POWERED EXCAVATORS The safety and accident-prevention regulations valid in the respective country must be observed.

The following requirements are based on extracts from the German accident prevention regulations "Electrical Systems (BGV A3)".

The installation, modification and repair of the electromechanical component of electrical systems and components must be delegated only to qualified electricians or firms employing such experts.

A "qualified electrician" in the context of this regulation is a person who, on the basis of specialized training, know-how and experience as well as knowledge of the relevant regulations, is in a position to judge the extent of the work assigned to him and to recognize any potential hazards.

The machine owner/contractor must inform all persons working on electrical installations and components or in the vicinity of components conducting electricity during operation, or who are responsible for the operation of electrical systems, of the potential danger of electricity and must instruct them on the accident prevention regulations relevant to their work. Instruction in safety measures is to be repeated at intervals appropriate to the operating conditions. If necessary, special working regulations must be displayed.

The excavator and its electrical systems must be adequately protected against other potential hazards of electricity, e.g. fire and explosion.

Electrical systems and components must be protected against electric shock in the case of a fault, e.g. short circuit to exposed conductive part.

Any parts of the electrical system conducting current when in operation must be housed in lock-up switchgear cabinets. Hazard warning signs are displayed on these lock-up cabinets.

VOLTAGE HAZARD The switchgear cabinets must be secured against unauthorized opening. The key must be kept by the electrician in charge.

Electrical systems and components must not be used unless they comply with the operational and local safety requirements. They must be in an orderly state and must be kept in such a state.

Any defects or malfunctions occurring in electrical systems or components must be reported to the electrician in charge.

Before switching on any systems, the excavator operator must check that no one is working on the machine or its electrical systems.

The heavy-duty power cable must never be driven over, buried or ripped away. The excavator equipment must never be set down on the power cable.

When the excavator is being moved, the cable must never be pulled or dragged over the ground.

Whenever work is being carried out on electrically powered excavators, the general rules of engineering - especially those concerning low and medium voltage - must be observed. Regulations such as those issued by the German VDE, e.g. specification VDE 0100, should be observed. Observe all the related laws and rules in your state or country.

Before commencing any work on electrical systems and components, the electrician in charge (or an electrician appointed by him) must switch the power off all circuits and lock them in the OFF state as follows:  Switch voltage OFF all systems.  Check with voltage detectors that all systems are voltage-free.  Lock switches/systems to prevent them from being switched ON. The above procedures must be carried out in the given sequence.

OPERATING INSTRUCTIONS RH200 Electric Introduction FIRE AND EXPLOSION HAZARD Prior to commencing work, obtain informationon the national and corporate rules for the prevention of accidents.

Pay particular attention to hazards caused by combustible and easily flammable substances.on the safe handling of the fire extinguishers to be used.

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

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

If necessary, also cover the ground with fireprotective blankets.

Ensure sufficient ventilation.

Clean the excavator before starting a job.

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

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

Combustible and easily flammable substances or liquids increase the fire and explosion hazard.

Do not store or handle any flammable substances during operation.

Do not extinguish flammable liquids with water.

Use:  dry-powder, 

carbon-dioxide or



foam extinguishing compounds.

Clean the excavator thoroughly, if possible, with a steam jet (rubber parts and electric components with compressed air - refer to information label), when, for example, oil, grease, fuel or cleaner was spilled.

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.

Such substances may spontaneously ignite if they get into the vicinity of hot units or objects such as turbo superchargers.

DANGER TO LIFE

Even battery gases can ignite in open flames or fire.

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

Call the fire brigade.

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

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 RH200 Electric OPeration Undercarriage 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.

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

Drive The drive unit comprises electric motor, 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 pressurerelief valves. The hydraulic pumps are supplied with oil from a hydraulic reservoir.

Programmable Logic Controller (PLC) The SPC controls the functions  Switch on electric motor, 

Switch off electric motor,



Central lubricating system,



Further auxiliary functions.

Further information is given in the Technical Handbook: "Programmable Logic Controller (PLC)".

Control Management System (CMS) 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.

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 electric motor can furnish. A microprocessor ensures that the hydraulic output power of the pump is optimally suited to the actual operation conditions.

The PMS boxes (load-limit regulators) are installed in a control cabinet in the cab module.

BA RH200(3 725 049.00)-EN

OPERATING INSTRUCTIONS RH200 Electric 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:  minimum power losses, 

reduced temperature of the hydraulic oil,



greater service life of hydraulic pumps and electric motor.

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 Board-ControlSystem operating instructions.

Switch on the electric motor only when all these work on the excavator is finished and all persons leave the danger area.  Switch on battery main switch (see: "Battery main switch, switching on and off").  Switch on electrical system (24V) (see: "Electrical system (24V), switching on and off").  Check telltales (14 and 16, Fig. 2-81:), they must lit up in green colour.

If so, electric motor can be switched on (see: "Switching the electric motor on").

Fig. 2-81:

If telltales didn`t lit up in green colour, BCS has detected critical operating conditions or faults which prohibit starting the electric motor. BCS indicates this case with telltales (for instance 15, Fig. 2-81:) as well as by displaying corresponding text.

Switching the electric motor on  Actuate switch-key (51, Fig. 2-82:), the electric motor is switched on.

During starting period the electric motor heavily warm up. Therefore it is not allowed to switch it on and off at will. By means of an electronical time-out circuit (PLC) the electric motor can be switched on only three times a hour (time-out period is 30 minutes).

OPERATING INSTRUCTIONS RH200 Electric OPeration Switching the electric motor off

Time-out before restart

During breaks in operation and at the end of each shift, the working equipment must be lowered onto the ground.

During starting period the electric motor heavily warms up. Therefore it is not allowed to switch it on and off at will. By means of an electronical timeout circuit (PLC) the electric motor can be switched on only three times a hour (time-out period is 30 minutes).

The electric motor must NOT be switched off until the equipment is resting on the ground.

To avoid straining the vacuum contactor, the electric motor should be shut down only when load-free, i.e. without any of the hydraulic units being activated at the same time via the control valve.  Actuate switch-key (52, Fig. 2-83:). The electric motor starts running down.  Turn key in key-switch (32) counter-clockwise and withdraw.

The control voltage is switched off.

The electric motor only can be switched on again, after the time-out period (30 minutes after last switching on) is over (see: "Time-out before restart", "Before switching on the electric motor" and "Switching on the electric motor").

The 30 minutes period means the time from switching on the electric motor up to the next switching on, e. g.

Electric motor is switched on, runs 20 minutes and then is switched off. Now the time-out period is 10 minutes before restart.

After running more than 30 minutes without interruption the electric motor can be switched on without any time-out period.

PLC prohibits switching on the electric motors until they are cooled down.

Monitoring lamp (14, Fig. 2-84:) on the BCS display is flashing in yellow colour until the time-out period is over. The remaining time is displayed also.

Monitoring lamp lit up in green colour when the time-out period is over and PLC enables switching on the electric motor.

OPERATING INSTRUCTIONS RH200 Electric OPeration Electric motor can not be switched on If BCS prohibits switching on the electric motor the operator should check the following:  Time-out before restart period still running? 

EMERGENCY STOP switch in control column unlocked?



EMERGENCY STOP switch in control cabinet (400V) unlocked?



EMERGENCY STOP pullswitch near the service station unlocked?



Servicing switch unlocked?



Monitoring lamps "6.6 kV OK" and "PHASE SEQUENCE OK" on the control cabinet (400V) and on the control column lighting?

If not, the circuit breaker is switched off or the 6.6kV voltage supply is missing.

 

Shut-off flaps at the hydraulik oil reservoir closed?

Check BCS display: Faults or explanatory text displayed? If so, give information to the electric maintenance personnel.

In case of failure If failures in the electrical systems occur, BCS displayes warnings and corresponding explanatory text Failures in electrical systems may exclusively be removed by specialist personnel for maintenance and service on electrical systems.

The following faults may be responsible:  fault in high-voltage transformer 

6.6 kV/ 400V/ 230V transformer overloaded.



earth fault.

If BCS display shows "Overcurrent", the operator does not know if an "Earth fault" happens. In worst case the excavator may be energized.

The operator must notify the electrician in charge from the excavator superstructure.

The electrician must then cut off the voltage supply from the transformer station and locate and rectify the fault.

If after all of these checks the electric motor cannot be switched on the operator has to inform the specialist personnel for maintenance and service on electric excavators. Only these have the skills to work in a safe way, for trouble shooting and removing the fault.

OPERATING INSTRUCTIONS RH200 Electric OPeration CORROSION PROTECTION FOR PINS AND BEARINGS (BUSHINGS AND HUBS) Use GLEITMO 815 anti-corrosive agent only.

Other agents are not approved by Bucyrus HEX. All pins and bearings (bushings and hubs) of the working equipment or in equipment componenents must be treated GLEITMO 815 anti-corrosive agent before fitting.

GLEITMO 815:  permits easy fitting and dismantling, 

protects against rust, oxidation and similar wear,



prevents seizing and fretting corrosion in nonmoving parts of bearings.

This is achieved by aluminium and copper particles forming a protective layer on the metal. This layer removes surface irregularities and does not sweat, seize or harden.

Application of GLEITMO 815  Clean off grease, oil, dirt and corrosion protection agents from pins and bearings using white spirit or diesel fuel.

Rust patches must be thoroughly removed, if any.

All parts must present a dry, bright metal surface.  Apply a thin layer of GLEITMO 815 on pins and all bearings using a brush or a spray can.

Pin shafts and bearings must be completely co-vered by the protective layer.

If the protective layer of a pin already treated with GLEITMO 815 is damaged, these areas must be touched up before fitting the part.  Fitting and securing of pins If the pin is too heavy to be fitted manually, apply GLEITMO 815 at first only on abt. a quarter of the pin's length Then position pin by means of a lifting gearready for fitting.

Apply GLEITMO 815 on the remaining length of pin shaft, fit pin and secure.

Part number of GLEITMO 815 is 2764305. Available from Bucyrus HEX Spare-Parts Service.

OPERATING INSTRUCTIONS RH200 Electric Inspection and servicing LUBRICANTS Notes on the selection of oils and greases 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.

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). 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.

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.

OPERATING INSTRUCTIONS RH200 Electric Inspection and servicing SERVICING WORK Hose line for oil changes Collect escaping oil and cooling liquid and discard 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. 3-15:).

Fig. 3-15:

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.

The swing gearboxes are equipped with automatic drain valves (1, Fig. 3-16:) These automatic drain valves permit oil changes without polluting the environment.

Change oil as follows:  Place a collecting recipient for used oil under the corresponding automatic drain valve. For the recipient capacity refer to the "Re-filling quantities - Oil" table or to the "Refilling quantities - Other" table.

Fig. 3-16:

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

OPERATING INSTRUCTIONS RH200 Electric Inspection and servicing ELECTRICAL SYSTEM Electrical system - Safety instructions

Risk of injury caused by battery acid and gases.

Wear goggles, working gloves and firm working clothing.

Read and observe the "Inspection and servicing – Safety instructions" chapter.

Carry out voltage and continuity checks only by means of a test lamp or a measuring instrument.

Do not check by "touching ground" with a bare wire. The short-circuit thus produced damages the alternator and the electronic modules of the PMS.

Interrupt electrical circuits with the circuit breaker before start working on the electrical system. All electric lines upwards from the circuit breaker are then without voltage (refer to the "Safety instructions for excavators with electric motor" at the beginning of this chapter).

The electrical circuit diagrams are annexed to the spare-parts list. Further information can be found in the Bucyrus HEX Technical Handbook "Working with circuit diagrams".

Before starting live-line servicing work e.g. measuring and testing with voltage applied, press switch (4, Fig. 3-23:) and secure it with a padlock.

Now voltage is supplied to the whole system but the electric motor can not be switched on.

This prevents accidents, inadvertent starting of the electric motor, and short circuits.

Cables and cable lugs must not get in contact with other metal parts. Replace broken or damaged cables and the respective cable lugs.

If a bulb does not work after replacement, the pertaining fuses, connection cables and contacts must be checked.

The 24V circuits are energized by the two batteries when the circuit breaker is switched off. These lines can also be de-energized with the battery main switch. Shut off the electrical system with the battery main switch when carrying out repair work or during prolonged downtimes of the excavator.

Gas-discharge lamps in Xenon working lights are operated with high voltage.

OPERATING INSTRUCTIONS RH200 Electric Inspection and servicing Floodlight projector, replacing the lamp Safety instructions The floodlight projectors use xenon technology.

The lamp is not a usual incandescent lamp, but a gas discharge lamp which is operated with a ballast unit. The ballast unit is integrated in the floodlight projector.

When the projector is turned on, the ballast unit generates a high-voltage pulse of more than 25000 volts to start the xenon lamp.

Warning!

This high-voltage pulse can be a lifethreatening risk, if a person comes into contact with any of the live components. This can be the case, for instance,  if the lamp is operated improperly,  

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.

Do not switch on the electric motor when the hydraulic oil reservoir is empty. The hydraulic pumps may be destroyed if they are allowed to run dry.

Details for selecting the correct hydraulic fluid refer to chapter “LUBRICANTS”.

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). 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.

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.

Check the hydraulic system under load. Pay attention to noises produced by the hydraulic pump or the hydraulic motors. Abrupt movements of the working equipment are a sign of entrapped air in the system. Remaining air pockets can be eliminated by actuating all hydraulic functions. 

If, for assembly reasons, the piston rod is inmiddle position, admit oil first to the piston-side port (4).

When oil is admitted for the first time to the cylinder, the oil flow must be reduced. Therefore extend or retract the piston rod as slowly as possible.

Hydraulic cylinder Before the initial admission of the cylinder with oil, the piston must be in either of the two extreme piston positions. In other words, the piston rod (1, Fig. 3-61: and Fig. 3-62:) must be either completely retracted or completely extended.

The screws/nozzles of the following components must be opened until oil emerges bubble-free from the opening: Always vent only the system section that has been opened.

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 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:

Group III p ≥ l bar and p·x l ≥ 200 bars

OPERATING INSTRUCTIONS RH200 Electric Repair work HYDRAULIC SYSTEM Repair Always depressurize the hydraulic system before disconnecting any hydraulic hoses or pipes.

Read and observe also the chapters "Inspection and servicing - Safety instructions" and "Repair - Safety instructions".

Replace damaged and leaking hydraulic hoses and pipes as soon as possible by new ones.

Use original spare parts from Bucyrus HEX. They are adapted to the respective function.

Do not re-use old hoses.

Never repair damaged hoses.

Discard escaped oil and oily wastes without polluting the environment. These substances must not be allowed to penetrate into the soil.

4-8

Hydraulic hoses – Instructions Even hoses that have been properly stored or used are subject to natural ageing. Their useful life is therefore limited.

Hydraulic hoses must replaced after a service life of six years (including a storage time of 2 years).

Check the date of manufacture on the hose or on the hose fitting regularly.

The recommended interval after which hydraulic hoses - and especially those used in harsh conditions - must be replaced depends on the number of operating hours and on pressure loading.

The use of hoses close to their recommended load limit shortens the replacement interval (e.g. high temperatures, frequent working cycles, extremely high pulse frequencies as well as multi-shift operation and round-the-clock work).

Hydraulic hoses must be replaced, if one of the following defects is detected during a visual inspection:  Damage to the outer fibre reinforcement layer reaching down to the inner layer (cuts, chafe marks, cracks). 

Embrittlement of the outer fibre reinforcement layer (cracks in the hose material).



Changes in the ususal shape of the hose under pressure or in pressureless condition in bends or curves such as detachment of fibre layers, formation of bubbles or bulges.



Leaks.



Non-observance of fitting requirements.



Damage to or deformation of hose fittings that may result in a reduction of the strength of the screwed union.



Detachment of the hose from the fitting.



Corrosion in fittings reducing the strength of the function of the fitting.

OPERATING INSTRUCTIONS RH200 Electric Repair work PRESSURE ACCUMULATORS SAFETY INSTRUCTIONS The hydraulic system is equipped with pressure accumulators containing nitrogen under high initial pressure.

Even when the hydraulic pressure in the system is reduced, the nitrogen in the accumulator will remain under pressure.

The accumulators are completely safe in operation. If incorrectly handled, however, there is a risk of explosion.

So:  Never handle accumulators never weld or solder.

mechanically,

 Testing and servicing work must be carried out by experts only.  Prior to any testing and servicing work, depressurize the hydraulic part of the system.  To dismantle the accumulator, always wear goggles and working gloves.  Fill accumulator with nitrogen only, never with compressed air or oxygen.  Report any defects or damage to the machine owner without delay.  Prior to recommissioning, an inspection by a specialist or expert is essential if the accumulator was damaged or if the admissible operating temperature or operating pressure was exceeded.

Never remove or paint over warning and information plates, rating plates or type identification markings. Replace illegible or damaged plates immediately

OPERATING INSTRUCTIONS RH200 Electric Repair work WELDING OPERATIONS SAFETY INSTRUCTIONS

Prior to any welding operations on the machine:  Set the battery main switch to OFF

Never perform welding operations unless you are qualified to do so.

Protect the disconnected terminals and plugs from short-circuiting and soiling by covering them with foil or adhesive tape.

Observe the accident prevention regulations.

Attach the welding-current pincers close to the welding zone (max. 2 - 3 m (6.6-9.8ft)).

Wear protective clothing  protective suit 

protective gloves



face protection

Any work on receptacles that contain or have contained substances  which are combustible or which encourage combustion, 

which are susceptible to explosion,



or which may develop health-hazardous gases, vapours, mist or dust

The welding current must not flow via the ball resp. the roller bearing swing ring, via pin couplings, articulated joints or hydraulic cylinders.

An electric current flowing over an air gap (in an articulated joint, for instance) generates sparks that damage metallic surfaces.

On completion of the welding operation, restore all electrical connections.  Set the battery main switch to ON

during welding operations must be carried out only under expert supervision and only by experienced persons authorized to do such work.

Detailed information on the correct execution of welding operations is given in the technical manual "Welding for maintenance and repair".

Should you have any problems or queries, apply to the Bucyrus HEX after-sales service department.

If parts of the machine have to be dimantled, read and take note of the following sections: Assembling attachments - safety instructions", "Inspection and servicing - safety instructions", "Repair - safety instructions".
