The Operation and Maintenance Manual 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 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 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 CGM HMS GmbH mechanic or by attending an CGM HMS GmbH training course for operators or maintenance personnel.

The CGM HMS GmbH after-sales service will be pleased to deal with any queries you may have after reading through the Operation and Maintenance Manual.

All CGM HMS GmbH Operation and Maintenance Manuals are issued in German and then translated. Even a good translation may give rise to questions which CGM HMS GmbH will be pleased to answer.

The Operation and Maintenance Manual are not work instructions for carrying out major repairs.

Such work is willingly done for you by the CGM HMS GmbH 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 Operation and Maintenance Manual, 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:

documentation of the engine and of other components,

Introduction WARRANTY The warranty of CGM HMS GmbH presupposes among other things that the servicing works as described in the Operation and Maintenance Manual have been performed: 

in a workshop authorized in writing by CGM HMS GmbH ,

and 



by the CGM HMS GmbH Service

or 

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

by using the original spare parts of CGM HMS GmbH .

The proper execution of the servicing works must be documented on the CGM HMS GmbH Service checklists.

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

In cases of doubt seek advice from the CGM HMS GmbH Service.

CGM HMS GmbH 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 CGM HMS GmbH 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.

Prior to commencing work, obtain informationon the national and corporate rules for the prevention of accidents and avoiding fires.

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

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

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.

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.

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

Do not store or transport flammable substances on the excavator during the work. 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.

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

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

Even battery gases can ignite in open flames or fire.

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.

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.

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

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.

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 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.

2-8

Control and Monitoring Platform (CAMP) The electronic CAMP system ensures the control and monitoring of all electrical and hydraulical functions of the excavator.

Four interconnected electronic units ensure optimal use of the installed engine power. Microprocessors are used to adapt the power output of the hydraulic pumps optimally to actual operating conditions. The machine is thus prevented from demanding more hydraulic power than the diesel engines can provide.

The desired working movements are detected by microcontrollers which permanently sense the position of hand levers and pedals.

As soon as movement is detected, the corresponding signals are transmitted to the electronic units. These units activate the drive control in order to provide the hydraulic energy needed for working. Only then do they activate the electrohydraulic valves which control the execution of the working movements.

BI015327 BA RH120E(3 725 082.01)-EN

Operation Board-Control-System (BCS) The BCS is a micro-processor-controlled system for the acquisition and processing of measuring data. It's function consists in collecting data of the excavator operating conditions and to evaluate, store and display these data to the excavator driver. For this purpose, the BCS is connected via a bus system to the Control and Monitoring Platform (CAMP). An interface with the outside world ensures the transfer of stored data and software updating.

The measured values (actual values) from the sensors and transducers installed in the excavator are compared to the predefined reference values.

Inadmissible deviations are indicated as fault messages on a display screen. Sensor or transducer defects or defective connecting cables are detected and indicated by plain-text messages.

The data from the engine electronics are acquired, processed and displayed in the same way.

Critical states of operation are brought to the driver's attention by means of optical and acoustic warning signals.

The display screen of the BCS is a touch-screen with a surface sensitive to the touch. This feature supports the excavator driver or the service technician in navigating through the menus of the BCS sorftware.

For further information in this respect, please refer to section 5 in this Operation and Maintenance Manual or to the brochure "Board-Control-System – Operation and Maintenance Manual"

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.

Automatic reset to idling If no servovalves are actuated by the control pedals or levers for more than 8 seconds (factory-set value, adjustable), the engine is automatically set back to idling speed (factory setting ca. 1000 rpm, adjustable). This feature, too, contributes to reducing the fuel consumption.

Electrical system The electrical system operates on 24 volts.

Operation Emergency shut-off function The emergency shut-off function can be triggered from five different places on the machine:  by pressing the switch (red) on the front panel of the control column (35, Fig. 2-32:),  by pressing the switch (red) on the drive regulators on the right-hand and on the left-hand side (Fig. 2-33:),  by pressing the switch (red) on the control cabinet in the engine module (Fig. 2-34:),  by pulling the pull-switch below the counterweight on the left (5, Fig. 2-35:).

The emergency shut-off function disconnects all power outputs of the electronic control units. In this case, all engines are shut off and all valves are deenergized so that no working movements can be performed anymore.

Fig. 2-33:

The power supply of the electronic control units of the engines (ECM) and of the machine (BCS, SPS) is, however, not interrupted. For this reason, the monitoring functions continue to remain active.

Other auxiliary functions such as:  the fire extinguishing system,  the service station (tank-lift) and,  the radio, the cab interior lighting and the access ladder lighting remain functional as well.

Fig. 2-34:

The emergency shut-off function can also be triggered before maintenance operations are performed on the machine. For this purpose, one of the switches is depressed and secured with a padlock. Any inadvertent starting of the engine is thus prevented.

Fig. 2-35:

Putting the machine back into operation The machine can only be put back into operation when all switches listed above are again in their basic position (i.e. not actuated).

Operation TRAVELLING Superstructure basic position Travel direction and sense of actuation of pedals (112 and 113, Fig. 2-111:) are identical only when the excavator is in its BASIC POSITION (Fig. 2-110:).

Travelling forwards/backwards Travelling forwards:  depress pedals (112 and 113) forwards.

The excavator travels in the direction of the idler (2, Fig. 2-110:).

Travelling backwards:  depress pedals (112 and 113, Fig. 2-111:) backwards.

The excavator travels in the direction of the drive sprocket (4, Fig. 2-110:).

During travelling, an acoustic warning signal sounds (Travel Alarm).

Fig. 2-110:

If the superstructure is swung out of its basic position by more than 90° (Fig. 2-112:), the excavator moves in a direction opposite to that expected when pedals (112 and 113, Fig. 2-111:) are depressed.

Fig. 2-112:

The pedals return automatically to their "0" positions when released.

Reverse the excavator only over short distances and with the assistance of marshallers because of restricted rear-view conditions.

Do not travel across slopes.

When travelling uphill or downhill, the travel drive must always be at the rear.

Travel only in the basic position of the excavator and only forwards.

Be extremely careful on slippery and greasy ground.

Fig. 2-111:

If the operator is not completely sure of the position of the superstructure with regard to the undercarriage, pedals (112 and 113) should be depressed slightly in order to find out which way the excavator moves before initiating the full travelling movement.

Operation WORKING OPERATION - SAFETY INSTRUCTIONS Read the sections "Fundamental safety instructions" and "Operation, safety instructions" carefully and observe the instructions given in them.

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:

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

 Start up the engines and run at low speed.

The pressure-limiting valve in the hydraulic system must not respond

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.

 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.

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;

 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 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 / CONSUMABLES".



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

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:



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

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.

Operation On-board crane, putting into operation Risk of serious injuries due to movements of the crane.

Put the crane into operation only after all persons have left the danger area.

Do not exceed the maximum lifting capacity (observe the lift capacity chart attached to the boom).

On-board crane, drive unit The drive unit (Fig. 2-136:) supplies the crane with hydraulic power. So the on-board crane is functional without the shovel’s engines running.

The drive unit comprises the diesel engine, fuel tank, starter batteries and the hydraulic system.

The drive unit is equipped with an Emergency OFF push switch (arrow, Fig. 2-136:).

In case of emergency push switch, the engine of the drive unit comes to standstill.

Prior to each deployment: Carry out all maintenance work as listed in the “Inspection and Servicing Plans “T” and “W”.

To start the drive unit:  Turn key-switch (5, Fig. 2-136:) to position ON.  Press button (6), engine will start.

The crane control unit is equipped with an Emergency OFF push switch (11).

In case of emergency push switch, the engine of the drive unit comes to standstill.

After finishing work block the boom, then stop the engine (see chapter “On-board crane, - blocking the boom in position of rest”).

Operation On-Board crane, – blocking the boom in position of rest Movements and accelerations produced by working operations of the machine can cause damage to the slewing drive of the on-board crane, if the crane is not blocked.

The hydraulic on-board crane must therefore be blocked in its position of rest.

Risk of serious injuries due to movements of the crane.

Put the crane into operation only after all persons have left the danger area.

To block the boom:  Retract the boom completely.  Slew the boom in the direction of the blocking device (Fig. 2-137:) and lower it.  Withdraw the cotter pin at the tip of the boom.  Extend the boom carefully until the tip engages the blocking device (arrow, Fig. 2-137:).  Reinsert and lock the the cotter pin.

Checking the on-board crane Extract from the inspection and testing regulations The on-board crane is approved in accordance with the Accident Prevention Regulations for Cranes (BGV D6, applicable only in Germany).

The on-board crane must be inspected regularly in accordance with the regulations in force in the country of use.

The inspections must be requested by the user of the crane. The expert or specialist entrusted with the inspection can be appointed at the user's discretion.

The user must ensure, however, that the appointed person meets the requirements.

The user is obliged to make available all documents required for the inspection and to ensure the smooth running of the inspection. He is furthermore obliged to provide, if required, crane operators and auxiliary personnel and the required test loads.

The result of the inspection is to be documented in an inspection record signed by the inspector.

The inspection record serves as proof on the part of the user that the inspections have been carried out. The inspection record must contain all data required for crane identification and for the performance of further regular inspections.

Pay special attention to: „Fundamental safety instructions" and all warnings and safety instructions attached to the machine.

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

Climbing onto and off the machine Use only the ladders, steps, platforms and handrails provided when climbing onto or off the machine.

The operating manual lists all jobs to be done. The descriptions of job sequences, however, provide only

Always keep ladders, steps, platforms and handrails in a non-slip, safe state and remove any oil, grease, soil, clay, snow, ice and other foreign matter immediately.

Experienced personnel with the necessary instructions.

Always face the machine when climbing on and off.

The operating manual must be kept with the machine at all times.

Always maintain a three point contact with the steps and grab handles.

Inspection and servicing personnel

Checking the state of tools

Inspection and servicing personnel must have the necessary know-how on the inspection and servicing of this or comparable machines.

Use only fully functional, reliable tools.

The necessary know-how can be acquired in a several day's instruction, e.g. by an CGM HMS GmbH mechanic or by attending an CGM HMS GmbH training course.

Personal protective equipment and working clothing 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, gloves and, in the event of high noise levels, ear protectors.

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

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.

Select the right tool for the job.

Wrenches of the wrong size, for example, may slip and cause injury.

Cleaning jobs Prior to commencing work, clean your working area, if necessary and possible, with a stream jet (rubber parts and electric components with compressed air - refer to information label).

Exhaust pipes and turbo chargers in the engine compartments are covered with special heatinsulating material. This material must not be spray-washed with steam-jet cleaners or highpressure cleaners. It will be damaged. Therefore cover all the insulating material with plastic foils before using steam-jet cleaners or high-pressure cleaners inside the engine compartments.

Use only lint-free cleaning rags when working on the hydraulic system or the engines.

Cleaning agents and solvents may give off harmful, readily flammable vapours. Never work with such agents except on well ventilated premises; never inhale the vapours and never smoke.

Prevent solvents and cleaning agents from coming into contact with your skin.

Wear gloves.

Observe the instructions on the packaging.

Inspection and servicing Handling flammable liquids

Visible oil losses

When handling flammable liquids:  never smoke,

Have any visible leakage repaired immediately.



keep away from unshielded light sources and naked flames,

Soak up any oil that has escaped with a binding agent.

Fuel and other consumables often have low flash points and are readily ignited. Never attempt to extinguish burning liquids with water.

Sweep up binding agent and dispose of it separately from other waste.

Use:  dry powder,

Relieving residual pressure in the hydraulic system



carbon dioxide or



foam extinguishers.

Only unpressurized hydraulic systems may be opened. 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 CGM HMS GmbH. They are the only ones to fulfill the technical specifications of the machine.

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

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

Screwed connections, piping, hydraulic hoses 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.

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

Used oil may be harmful to the skin.

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

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 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.

Inspection and servicing Non-polluting disposal

Engine exhaust gases

Dispose of oils, greases, cooling liquids, detergents, solvents and oil-containing components, such as filters, cleaning rags, replaced wearing parts and unusable machine parts, without polluting the environment and separately from other waste.

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

Do not dispose of these substances together with household wastes.

In closed rooms, exhaust gases must be evacuated to the outside; Do not work on the exhaust system an do not make any modifications to it;.

Fill these substances into the containers provided for such purposes.

Exhaust gases from diesel engines and some of their constituents may cause cancer, birth defects and other reproductive harm.

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

Handling batteries

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.

Seals Individual spares may contain asbestos. Such spares or their packaging are marked with: Never process spares containing asbestos mechanically. Inhaling asbestos dust is a health hazard.

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

Wash hands after handling.

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.

Clean sealing faces prior to assembly.

Inspection and servicing 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.

Selecting oils and greases Use the recommended qualities only, matching viscosities with the temperature level.

Filters

Disconnect first the negative and then the positive terminal.

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

After the work:

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

Reconnect first the positive and then the negative terminal.

Handling of cold-starting fluid (ether) 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.

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 / 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.

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.

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

On completing work, re-install all protective devices.

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

Carry out performance tests with the machine.

BI015327 BA RH120E(3 725 082.01)-EN

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.

Inspection and servicing LUBRICANTS / CONSUMABLES

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). 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.

Original CGM HMS GmbH 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 CGM HMS GmbH Operation and Maintenance Manual contain specifications for the oils and greases that are approved for use in CGM HMS GmbH machines. These oils and greases are especially adapted to CGM HMS GmbH 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, CGM HMS GmbH 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 CGM HMS GmbH Operation and Maintenance Manual.

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 CGM HMS GmbH specifications, CGM HMS GmbH 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.

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.

Inspection and servicing SERVICING WORK Hose line for oil and cooling liquid changes Collect escaping oil and cooling liquid and discard without polluting the environment.

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.

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.

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.

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 dispose of in fire.



Keep the vessels in a place unaccessible to unauthorized persons.



Dispose of the vessels properly.

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

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

Avoid skin contact. Wear suitable protective gloves and goggles.

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 up to 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.

Inspection and servicing Lighting systems in LED technonogy, instructions The lights of the maintenance lighting system (Fig. 3-63) as well as the working floodlights (Fig. 3-64) are equipped with lamps in LED technology (lightemitting diodes).

High-performance LEDs ensure the emission of light with high luminance. If the light is allowed to shine directly into the eyes from a short distance and over prolonged periods, there is a risk of injury to the retina.

Do not look for a prolonged period into the light cones of the LEDs. Adjust the lights in such way that they do not shine directly into the eyes and that you are not blinded by the glare.

The lights become hot in operation.

The heat is dispersed via the ribbed metal housing.

Fig. 3-63

For this reason, the housings must not be covered up and cleaning rags or similar things placed over them.

The high-performance LEDs in these lights have a very long service life and can therefore not be replaced. If one or more of these LEDs fail, the light can remain in service if the remaining luminance is still sufficient.

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. 3-65: and Fig. 3-66:) 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:

Shut off the engines.

The hydraulic oil reservoir itself may also be hot.

Avoid skin contact.

Skin contact with hydraulic oil may cause skin injury.

Wear protective gloves and firm working clothing.

Collect escaping oil and discard without polluting the environment.

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

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.

Open the highest leakage oil port and fill in clean hydraulic oil up to the lower edge of the opening.

• the piston-side port (3) when the piston rod is retracted (1, Fig. 3-99:), • the rod-side port (4) when the piston rod is extended (1, Fig. 3-100:).

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. 3-99: and Fig. 3-100:) must be either completely retracted or completely extended.

The bolts/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.



the travel brake valve at the venting screw,



the oil cooler manifold at the mini-measuring ports,



the servo system at the venting bolts of the control blocks (under the servo caps),

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

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: 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.

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".

Inspection and servicing CENTRAL LUBRICATING SYSTEM Design The excavator is equipped with an automatic central lubricating system which provides grease regularly to all greasing points except those mentioned in the "Lubricating chart - Grease".

The central lubricating system is activated when the electrical system is switched on with the keyswitch and at least one engine is running.

All greasing points connected to the system are greased at regular intervals.

The automatic greasing is interrupted when the engines are stopped with the idle timers.

The central lubricating system is controlled electrohydraulically by the PLC (Programmable logical controller).

The PLC is located in a switch box underneath the cab.

Fig. 3-147:

If a fault occurs, BCS gives a warning on the screen (Fig. 3-147:). This happens, for example, if the filter element in the hydraulic line is contaminated.

If one of the following faults occurs, BCS gives a warning and at the same time the grease pump is switched off: 

Grease container is empty,



Greasing pressure in the grease lines is below 250 bars (3626psi).

In this cases, BCS switches off the hydraulic function of the shovel/backhoe cylinders after 15 minutes. This prevents damages from lack of greasing.

Inform the responsible maintenance personnel immediately.

Keep on working after the fault has been fixed.

Fig. 3-146:

After the fault has been fixed, actuate the "Reset" button in the control column (64, Fig. 3-146:) or the “Reset” button in the control box located at the grease container. The buttons must be actuated for at least one second.

For further information on the function and setting refer to the Technical Handbook, chapters 9 and 11.

Inspection and servicing Function The grease is pumped by hydraulically driven pumps (2 and 3, Fig. 3-148:) via greasing lines from the grease container to the main distributors on the superstructure and on the undercarriage.

Pump (2) supports greasing points on superstructure and working equipment, pump (3) supports the undercarriage (optional).

The control elements of the lubricating system are installed on a control panel (1) attached to the grease container.

As soon as the grease container is empty, the BCS (Fig. 3-149:) gives a warning signal (fault). In the event of a fault, the "dumping” function (shovel or backhoe cylinder) is switched off automatically after 15 min.

Inspection and servicing Checking the greasing pressure

Unblocking a grease line

Check regularly (accord. to the maintenance plan), whether the oil pressure indicated by pressure gauge (3, Fig. 3-152:) at the hydraulic oil filter is 55 - 60 bars / 798 - 870 psi.

In the event of faults at the central greasing system inform the responsible maintenance personnel immediately. Detailled information about the central greasing system can be found in the “Technical Handbook” chapter 11.

The pressure is depending on temperature and viscosity of the oil and may vary.

This oil pressure is reduced so that the pressure indicated by pressure gauge (2) is 35 – 40 bars / 507 – 580 psi and by pressure gauge (1) is 49 – 51 bar / 711 – 740 psi.

The necessary greasing pressure of 320 bar / 4641 psi for the superstructure and 180 bar / 2611 psi for the lower carriage is generated by means of a pressure translator.

The greasing pressure for superstructure and working equipment is indicated by pressure gauge (4). The greasing pressure for the undercarriage (optional) is indicated by pressure gauge (5).

Even when the grease pump isn’t active, there can be residual pressures in the grease lines up to 30 bars (435psi).

Relieve this residual pressure before opening a grease line.

Put the excavator back into operation only after the greasing system works properly and after having actuated the unloaded working equipment for abt.

5 minutes. This is necessary in order to supply sufficient amounts of grease to the cylinder bearings.

In the event of deviating pressure values, shut off the engines and inform the responsible maintenance personnel. The central greasing system has to be checked.

Lower oil / grease pressure means that not all of the greasing points are supplied with grease.

Higher oil / grease pressure may cause bursting of a greasing line.

Repair work CONFINED SPACES - SAFETY INSTRUCTIONS Work in confined spaces can lead to unexpected dangerous situations, such as 

the formation of flammable vapours exploding during welding operations or



the lack of oxygen and harmful gases causing loss of consciousness.

What are "confined spaces"?

Confined spaces on this machine are, for instance, components of the working equipment such as the monoblock boom, the lower part of the boom, the stick or the hydraulic reservoir (Fig. 4-1: - Fig. 4-3:).

These components are provided with manholes.

Manholes offer access to the inside of these components in order to carry out inspections or repairs such as welding work.

Fig. 4-1:

Dangerous situations can also exist in other spaces which are not very often visited or which are badly ventilated. In these spaces, harmful or flammable gases can accumulate unnoticed.

Work in such spaces may only be carried out by specially qualified persons who have been instructed as to the situational risks.

Before visiting these spaces, the following safety precautions must be taken:  The narrow space must be ventilated for a prolonged time, e.g. with a blower. Do not blow oxygen into the space. Oxygen increases the risk of fire.

Fig. 4-2:

 Use your personal protective equipment, e.g. respiratory mask.  Use a safety harness and have a second person stand by with a rescue rope attached to the harness.  Evacuate the gases produced during welding.

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.

Repair work HYDRAULIC SYSTEM Repair instructions

Hydraulic hoses – Instructions

Always depressurize the hydraulic system before disconnecting any hydraulic hoses or pipes.

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

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 CGM HMS GmbH. 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.

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.

Repair work WELDING AND FLAME CUTTING WORKS - SAFETY INSTRUCTIONS The present safety instructions are valid for both types of work. For easier reading, the text only uses the terms "welding work", "welding" or simply "work". These terms do however always refer to both types of work, i.e. "welding and flame-cutting work".

Read these safety instructions before starting any welding or flame-cutting operations.

Welding work by qualified personnel only Carry out welding work only if you have received special training and if you have been ordered to perform such work.

Always bear in mind that you are performing welding work on heavily loaded components. The quality of your welding work can be decisive for the operational capability of the machine and also for the health and life of persons.

Observe the health protection and accident prevention laws and regulations as well as the fire protection regulations in force in your country.

Observe all warning and instruction signs attached to the machine.

Increased risk of fire during welding work Always bear in mind that the heat, the sparks or dripping red-hot metal or slag produced in the process constitute a considerable risk of fire.

The present safety instructions provide information on how to minimize the risk of fire.

Remove all combustible materials close to the welding location or cover them up with noncombustible materials.

If works in the vicinity of combustible materials cannot be avoided, further persons with firefighting equipment must be present on site as fireguards.

Observe the instructions of the machine owner and of the mine.

Health hazards Welding operations produce harmful gases. Do not inhale the fumes and gases and make sure the surroundings of the welding location are well ventilated or equipped with an exhaust system.

Remove all kinds of paint and all coatings as well as all residues of oils and greases from the weld area.

Do not wind the welding cables round your body or parts of your body. The electromagnetic fields produced may damage your health.

Wear the prescribed personal protective equipment such as:  protective clothing,  protective gloves,  protective mask and,  a fall-arrest system for persons working at height.

Repair work Tanks, pressure vessels and pressure accumulators Any work on vessels containing or having contained  combustible or combustion-accelerating substances,  potentially explosive substances or  substances susceptible to develop harmful gases, fumes, mists or dusts during welding may only be carried out under expert supervision and only by experienced personnel especially assigned to such work.

This prescription applies, for instance, to all tanks and reservoirs for hydraulic fluid, engine oil, diesel fuel or lubricating grease.

Welding work on pressure vessels and pressure accumulators is forbidden.

Pressure vessels containing cold-starting fluid (ether) may be installed in or near the engine compartment.

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 vessels against damage and high temperatures.

Do not perform welding work in the vicinity of these pressure vessels before they have been covered up safely against accidental contact or flying sparks. Have the pressure vessels removed from the machine, if safe protection cannot be ensured.

Inform yourself about the locations in the machine where the pressure accumulators of the hydraulic system are installed. Do not perform welding work in the vicinity of these pressure accumulators before they have been covered up safely against accidental contact or flying sparks. 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.

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 GmbH 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 technical handbook "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.

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.

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.

4-12

Disposing of the machine without polluting the environment Before stripping down the machine at the end of its service life observe the following instructions: The assemblies of the machine contain various operating fluids or lubricants. These substances may pollute the environment (so-called hazardous substances) and must therefore be disposed of properly.

Observe the national laws and regulations governing the non-polluting disposal of these substances.

Remove all operating fluids from the systems, remove all lubricants and dispose of these substances properly. 

Annex BOARD-CONTROL-SYSTEM BCS III, what’s that?

What it is The BCSIII is the third generation of the Board Control System. This generation represents the current stage of development of this reliable monitoring and control system for hydraulic mining excavators from CGM HMS GmbH. The BCSIII communicates with other electronic units in the excavator and makes up the CAMP system, the Control And Monitoring Platform.

Controllers actuate and monitor functions such as the motor management, drive and control of the hydraulic pumps, the servo control and others. The controllers are basically computers that have been configured for their special application.

Other electronic units of the CAMP system that communicate with the BCSIII are located in cabinets in the module below the driver’s cab, the pump compartment and the engine compartment.

The exchange of data between sensors, controllers, the BCSIII and other involved components takes place via the CAN bus.

What it does The Board Control System, abbreviated to BCS, monitors all the essential functions of the excavator and its components.

It releases an appropriate signal if any maximum value is exceeded and also sends a report to be archived in the memory bank.

If a normal operating status can be reached by temporarily reducing the excavator's output, then this is monitored by BCS and done by the CAMP system.

If it is necessary for the operator to take certain action, e.g. to stop one of the engines a relevant command is sent to the BCS display screen.

BCS also gives information on servicing and trouble-shooting.

Sensors installed at various points on the excavator constantly transmit their readings to the controllers of the CAMP system.

All essential pieces of operating data are displayed on the BCSIII screen in the form of simulated instruments as well as they are archived and can be called up as and when required.

Fig. 5-1:

Benefits for the operator Because BCS automatically warns of any abnormal conditions that require a corrective action, the operator can concentrate fully on the work in hand, and is not distracted by constantly having to keep an eye on many instruments or by having to decide upon appropriate actions to be taken in case of limit values being exceeded.

The operator and the servicing crew also have the means of calling up particular background information from the BCS archive.

The housing – installed in the control column inside the driver’s cab (Fig. 5-1:) – integrates the computer, the monitor, the control elements and the interfaces.

Want more information?

More detailed and more technical information for service personnel could be found in the “Technical Handbook”, chapter 9.

There are more extensive information given about the communicating units and about troubleshooting.

Annex BCSIII, the start screen The screen displays the graphical user interface of the Board Control System. The basic screen (Fig. 5-3:) appears when all electronic units of the CAMP system have started and when their selftests have been completed.

Note: At low outside temperatures it is possible that the basic screen appears a few minutes after switching on the electrical system (warming up phase).

Starting from this basic screen, the user can access a number of other screens. This does not require an input device such as a keyboard, mouse or similar.

The BCS screen is designed as a touch-screen. By slightly touching the active areas, the user can perform activities such as changing to another screen page.

Active areas are shown on the screen as threedimensional graphics. In the basic configuration – not activated - they seem to project out of the user interface. When touched, they appear to be lowered.

Never use pointed objects such as a ball pen, screwdriver, nail or similar.

This could damage the active surface of the touch-screen.

Annex TROUBLESHOOTING Instructions on troubleshooting Faults are often due to the machine not being correctly operated or serviced.

For this reason, it is vital to read through the relevant section of the Operation and Maintenance Manual once again before rectifying any faults.

If you are unable to detect the cause of the fault or to rectify it, apply to the CGM HMS GmbH aftersales service.

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

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.

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

Therefore make careful observations.

Study the problem carefully. First think, then act.

Ask yourself the following questions: 

Which warning signals preceded the fault?



What repair and servicing work was carried out previously?



Has this defect already occurred?



Is it one or several simultaneously occurring faults?

Possible causes 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.

Section This specifies where information on troubleshooting is given in the Operation and Maintenance Manual. If there is no entry, the CGM HMS GmbH after-sales service should be consulted

Annex ENGINE MONITORING, CONTROL LAMPS

Warning lamp, red (50 and 60): Ignoring the signal lamp may lead to a potential engine breakdown.

The control lamps 

(49 and 50, Fig. 5-22:) for the left engine,



(59 and 60, Fig. 5-22:) for the right engine,

indicate malfunctions and signal when certain limit values have been exceeded.

An automatic check is performed after switching on the electrical system of the machine; both lamps will light up for approx. 5 seconds and turn off afterwards.

The warning lamp lights up as soon as certain limit values for the following operating parameters of the engine have been exceeded: (An "Event“ occurred): 

Charge air temperature at engine intake,



Temperature of coolant,



Engine oil pressure,



Engine speed (protection against overspeed),



Fuel pressure,



Fuel temperature.

In case of an event (e.g. temperature of coolant is too high), the lamp will light up. The diagnosis lamp provides the event code at the same time (flashing).

In case of a previously specified threshold value, the engine will reduce the output (so-called "engine derate“). This is not indicated by the lamps, e. g.: 

Engine oil pressure approx. 1bar (14.5psi) (rotation speed dependent),

Diagnosis lamp, yellow (49 and 59):



The diagnosis lamp indicates malfunctions of the electronic control of the engine.

Temperature of coolant above 111°C (231.8°F),



Temperature of intake air above 86°C (186.8°F),



Temperature of fuel above 91°C (195.8°F).

Fig. 5-22:

For example: faulty sensors, cable breaks etc.

The indication uses so-called flash codes.

In case of a malfunction, the diagnosis lamp represents two digits, the "diagnosis code" or an "event code“.

This takes place by the flashing of the diagnosis lamp in quick succession.

The first and second digits of the flash code are derived by counting the flash signals.

In case of a reduced output, for example by exceeding the maximum working height, none of the lamps will light up or flash.

The limit values and the engine's response when those values are exceeded can be adjusted in the so-called monitoring system within certain limits (service provided by the engine manufacturer).

There is a time interval of approx. 2 seconds between the flashing sequence of the first and second digit.

In case of several diagnosis codes, the time interval between two different diagnosis codes is approx. four seconds.

Refer to the engine's operating and maintenance manual for matching the diagnosis and event codes with the cause of malfunction.

Diagnosis codes are intended to isolate an error and are not suitable for detailed fault diagnostics.
