Introduction PREFACE This Operation and Maintenance Manual is designed to familiarize the operator with the machine and its designated use.

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 operator's cab of the machine.

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

 

operation, including setting-up, troubleshooting in the course of work, care, evacuation of production waste and disposal of fuels and consumables, maintenance (inspection, servicing, repair) and / or transport.

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

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

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 after-sales service.

Further machine documentation The documentation relating to the machine is listed according to scope, quantity and language in the shipping note of the machine or in the covering letter if supplied separately. The operating instructions, the spare-parts list and the Service Manuals 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,

Volume 6:

Service Manual Part 1

Volume 7:

Service Manual Part 2

Depending on the size of your machine, the documentation can also consist of more volumes.

If you cannot find the information you are looking for in the present Operation and Maintenance Manual please check also the other volumes of the documentation.

The Service Manual Part 1 also provides information on how to assemble the machine, on functions of the hydraulic system, on hydraulic circuit diagrams etc.

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

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

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

Introduction WARRANTY The warranty of CGM HMS presupposes among other things that the servicing works as described in the operating instructions have been performed: 

by the CGM HMS Service

Do not operate the machine 

when components / assemblies are defective or missing,



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

or 

in a workshop authorized in writing by CGM HMS,

and 

by using the original spare parts of CGM HMS.

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

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

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

Therefore: Do not operate the machine, 

when several track rollers or support rollers have been removed;



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



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



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

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

Such circumstances are considered by CGM HMS 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.

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 slewing ring.

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

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:

Drive



reduced fuel consumption

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



minimum power losses



reduced temperature of the hydraulic oil



greater service life of hydraulic pumps and diesel engines.

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.

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

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

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

Operation TRANSPORTING THE MACHINE Transport - Safety instructions

The partly dismantled excavator can now be transported on a semi ow-bed trailer (low-bed trailer with front platform) (Fig. 2-61:).

The machine must be loaded and transported only after all safety regulations have been observed and complied with.

Entrust loading and transporting of the machine to a company experienced in the transport of heavy equipment.

The responsability for loading and transporting lies with the transport company or their representative.

Remove oil, grease, soil, mud, snow, ice and other materials from the excavator's crawler tracks and from ramps and loading platforms of the transport vehicle to minimize slipping.

Secure the transport vehicle against rolling away.

Use only tying equipment of sufficient strength (the weights and dimensions of the excavator are set out in the "Technical specifications").

Transport The dimensions and the service weight of the fully assembled excavator do not allow the excavator to be transported in an undismantled state on a lowbed trailer over public roads.

Therefore, the following components and modules must be dismantled beforehand:  Counterweight, 

driver's cab,



excavating tool (loading bucket, backhoe bukket),



Operation WORKING OPERATION Safety Instructions

Running-in instructions for hydraulic cylinders

Read the sections "Fundamental safety instructions" and "Operation, safety instructions" carefully and observe the instructions given in them.

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

Do not exceed the maximum machine inclination (see “Maximum machine inclinations, information” chapter.

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

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

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

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



In the first two working cycles, retract and extend the pistons of the hydraulic cylinders to max. ½ to ¾ (not to the limit stop).

Never change direction suddenly. The waiting time between changes of direction must be at least 4 seconds.



In the next eight working cycles, retract and extend the pistons of the hydraulic cylinders to the limit stop. The waiting time between changes of direction must be at least 4 seconds.



When all hydraulic cylinders have been run in, the excavator can operate at a higher engine speed.

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 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 as "abusive utilization".

Operation LIFTING OPERATIONS Safety instructions Never use the machine for lifting-gear operation unless it is equipped and approved for this purpose, i.e. the machine must be equipped with an overload warning system and a pipe break protection.

Read the sections "Fundamental safety instructions" and "Operation safety instructions" with care and observe the instructions contained in them.

Transporting the load Never move the load above persons. Keep the load as close as possible to the ground. Prevent the load from swinging The machine must never be driven with a slung load unless the road surface is even and the roadway is clearly visible.

Roadway visibility can be improved by adjusting the boom and slewing the superstructure to the right.

Switch the overload warning system on.

The built-in overload warning device cannot totally exclude accidents due to incorrect operation. This applies in particular to:  inadequate hooking of the load or the loadcarrying device,

(see "Technical data").



excessive deceleration or acceleration forces (hard braking or strong slewing with the load to be moved),

Room for slingers



loads dropping into the cable,

Slingers must approach the working gear from the side when the load is slung.



oblique pull,



driving the excavator into an area with steeply sloping ground,



exposure to strong wind.

During the lifting and transporting of loads, slingers or other assistant personnel must stand in a safe position or go beside the machine to ensure that they are outside the hazard zone.

Ensure that slingers and other assistant personnel are always in sight.

Slinging loads Use only tested and efficient lifting gear with an adequate load capacity.

Hoist the load only from the hooks provided for that purpose.

Never use the the teeth of backhoe buckets, shovels or grabs.

Cable lugs, thimbles or U-bolts may slip from the teeth, putting the load out of control.

Register the weight of the load. Sling only those loads not exceeding the load capacity of the lifting gear and of the machine Sling the load in such a way as to prevent it from slipping or falling while being lifted or transported.

Operation Overload warning system

Checking the overload warning system

Hydraulic excavators that are used as lifting gear or for the transport of loads must be equipped with an overload warning system.

Check the overload warning system for safe operation before beginning to work with the loadhook.

The overload warning system consists mainly of an electro-hydraulic switching unit which gives an optical and an acoustic warning signal before the maximum admissible load moment is reached.

Do not switch off the overload warning system when the warning signal sounds.

The overload warning system must be on during lifting-gear operation.

The overload warning system only gives warning signals.

It cannot avert the danger of overturning.

In case of malfunctions have the overload warning system immediately checked and repaired by CGM HMS. Do not make re-adjustments or repairs of the overload warning system.

Re-adjustments or repairs might lead to incorrect operation or failure of the system.

Putting the overload warning system out of operation Shut off the overload warning system if the machine is to be used exclusively for digging.

When the warning signal sounds: let the load down immediately

Pipe burst protection

reduce the working radius or the load.

The pipe burst protection prevents uncontrolled lowering of the working equipment if a hydraulic line to the boom cylinder bursts.

In spite of the overload warning system, the operator must assure himself beforehand that the load to be lifted does not exceed the excavator's lifting capacity.

The admissible load moment is exceeded if too big a load is being lifted with a large working radius of the equipment (lifting capacity see the "Lifting capacity of the excavator" section).

The hydraulic port on the rod-side of the boom cylinder is blocked off so that the hydraulic oil in the cylinder can flow out only if the "boom lowering" function is activated.

When a hydraulic line has broken:  Warn persons in the vicinity of the machine by sounding the signal horn.

Stop working.  Secure the area within reach of the working equipment and the attached load.

Persons must be prevented from entering the hazard zone under the working equipment or the suspended load.  Replace the broken hydraulic line or have it replaced before continuing the work.

Absorb spilt hydraulic oil and dispose of oil-soaked cleaning rags, binding agents, etc. without polluting the environment.

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.

Inspection and servicing Handling batteries

Handling of cold-starting fluid (ether)

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

Wash hands after handling

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

Batteries give off explosive gases.

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

Battery acid is toxic and corrosive.

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

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.

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

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

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

Provide for sufficient ventilation.

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

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

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

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

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

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

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.

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

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

Disconnect first the negative and then the positive terminal.

Wear suitable protective gloves and goggles.



Inspection and servicing Selecting oils and greases

After servicing

Use the recommended qualities only, matching viscosities with the temperature level.

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

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

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

Sealing elements When dismantling parts, watch for sealing elements.

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

When assembling, ensure a perfect fit.

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

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

Lubricating Clean the lubricating nipple, then lubricate as scheduled.

3-8

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.

BA RH40E(3 725 088.00)-EN

Inspection and servicing INSPECTION AND SERVICING, FIRE AND EXPLOSION HAZARD Safety Instructions Prior to commencing work, obtain information on the national and corporate rules for the prevention of accidents.

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.

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.

Provide for 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.

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.

Clean the excavator before starting a job.

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.

Inspection and servicing ENVIRONMENTALLY COMPATIBLE HYDRAULIC FLUID Environmentally compatible hydraulic fluid - operating instructions

Operating equipment and attachments driven with mineral hydraulic oil must not be mounted until thoroughly emptied, cleaned and flushed.

The hydraulic system of this machine can be filled ex works with environmentally compatible, synthetic hydraulic fluid as an option. In this case, the machine is supplied with stickers containing the corresponding instructions.

Environmentally compatible hydraulic fluid, conversion

For the initial filling, CGM HMS uses only: PANOLIN HLP SYNTH 68 CGM HMS (P/N: 2115005).

This synthetic hydraulic fluid has been tested by CGM HMS and approved for application in CGM HMS machines.

A change from mineral hydraulic oil to this synthetic hydraulic fluid can, however, be made also at a later date.

Environmentally compatible hydraulic fluid, too, must not be simply poured away but disposed of in the same way as used oil.

If hydraulic fluid seeps into the ground, the machine owner and the competent authorities must be informed. HLP SYNTH 68 is suitable only for hydraulic systems.

As HLP SYNTH 68 is not soluble in water This means that condensate may be deposited in the hydraulic oil tank.

It must therefore be drained off at regular intervals and after lengthy downtimes, then disposed of in the same way as used oil.

Use only HLP SYNTH 68 for changing or topping up the hydraulic fluid.

The hydraulic fluid must not be mixed with hydraulic oils or hydraulic fluids by other manufacturers, as this affects its biodegradability.

3-10

Analysis will show whether the hydraulic fluid can be used beyond the standard changing intervals.

See section: "Environmentally compatible hydraulic fluid, sampling"

Read and observe: "Inspection and Servicing - Safety Instructions".

 Bring hydraulic system to operating temperature.  Retract all hydraulic cylinders.  Drain off hydraulic oil (see operating instructions, section 3 "Inspection and Servicing").  Fill hydraulic oil tank with HLP SYNTH 68 up to halfway mark.  Activate all hydraulic functions including travelling for about 30 minutes. The hydraulic system is being flushed during this time.  Then drain off the hydraulic fluid.

The fluid can be used repeatedly for flushing.

Otherwise it must be properly disposed of. In this case, a disposal expert must be consulted as this is a mixture of synthetic hydraulic fluid and mineral hydraulic oil.  Change all filters in the hydraulic system.  Fill the hydraulic oil tanks with new HLP SYNTH 68.

BA RH40E(3 725 088.00)-EN

Inspection and servicing Fix an instruction sticker (sample see Fig. 3-1:):  in the cab, 

on the hydraulic oil tank and



on hydraulically-operated attachment.

Fig. 3-1:

Environmentally compatible hydraulic fluid - Sampling Complete sets are compiled for hydraulic fluid analysis. They contain all necessary parts.  Sets are available from the CGM HMS SpareParts Service: Part-No. 1 465 077. 

Hydraulic fluid analyses are performed by: WEARCHECK GmbH Bahnhofstraße 75 D-83098 Brannenburg



After 30 - 50 operating hours with environmentally compatible hydraulic fluid, take a sample of the hydraulic fluid.

Send this sample in to the above address for analysis. The company will then notify you of the result of the analysis.



After this, CGM HMS recommends sending in a sample for analysis every 1000 operating hours or once a year.

It is essential that the hydraulic fluid should be analysed not later than after 3000 operating hours.



The results of the analysis show whether the hydraulic fluid is still serviceable and the changing interval can be extended.

In case of questions contact the CGM HMS Service.

 Start up the machine. Check level in hydraulic tank according to servicing plan.  The hydraulic fluid may dissolve deposits in the hydraulic system.

So change all filters 30 - 50 operating hours after making the change.

Make further filter changes according to servicing plan.  Sample the hydraulic fluid after 30 - 50 operating hours and send in for analysis. (See section: "Environmentally compatible hydraulic fluid, sampling").

The maintenance intervals for components, e.g. engine and gearbox, are listed in the following CGM HMS maintenance schedules.

Change of engine oil l

It is possible that the manufacturer's documentation for these components states intervals deviating from the above-mentioned intervals.

The intervals stated for changing the engine oil apply to fuels with a sulphur content of ≤ 0.5% and a permanent ambient temperature down to –10° C / 14°F.

In such case, only the maintenance intervals specified by CGM HMS shall apply.

In case of higher sulphur content and/or a permanent ambient temperature of below –10° C / 14°F, shorter intervals are required.

If the engine oil change intervals are not reached within 6 months, the oil must be changed at least after 6 months.

Inspection and servicing LUBRICANTS Notes on the selection of oils and greases Original CGM HMS 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 Operating Instructions contain specifications for the oils and greases that are approved for use in CGM HMS machines. These oils and greases are especially adapted to CGM HMS 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 only approves the use of the specified oils and greases.

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 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.

All other qualities are not approved.

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

Alternative oils and greases

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.

The oils and greases filled into the machine must meet at least the specifications mentioned in the lubricants tables of the CGM HMS 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 CGM HMS specifications, CGM HMS does not assume any responsibility and does not accept any warranty claims.

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 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 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.

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 of the surroundings.

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

3-44

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.

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.

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



Inspection and servicing Floodlight projector, 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. 3-54) as well as the working floodlights (Fig. 3-55) 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. 3-54

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.

Do not start up the drive engine 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.

Inspection and servicing Pressure accumulator To permit lowering of the working equipment in case of emergency, the machine is equipped with a pressure accumulator (1, Fig. 3-77:).

The pressure accumulator (1) is located under the superstructure baseplate.

The following regulations are applicable only in the Federal Republic of Germany. Please observe the corresponding regulations in your own country.

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

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 under "Function".

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

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.



open or smouldering fire may occur.

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.

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.

Battery gases are highly flammable.

Explosion hazard.

Do not lean over the batteries when starting the machine from another vehicle.

Risk of injury from acid splashes and battery gases.

Never use assisted starting when the batteries are defective or frozen.

Never connect batteries (battery assemblies) unless they have the same voltage.

Use only tested jumper cables with insulated terminal clips and an adequate lead diameter.

Ensure that the bodies of the supplying and receiving machines are not in contact. Otherwise a current flow could result from connecting the positive poles. Risk of short-circuiting.

Never use welding generators or welding transformers as a source of current.

Position the jumper cables in such a way that they cannot be caught by rotating engine components.

Read and observe: "Inspection and servicing – Safety instructions", paying particular attention to the section "Handling batteries".

Assisted starting (with jumper cables) Prior to assisted starting Read and observe the section: "Assisted starting – Safety instructions".

Starting the engine with jumper cables (external batteries Before connecting the jumper cables (external bateries) check the own batteries for proper operation. Checking is done by switching on the excavator's electrical system.

Do not switch on electrical consumers (e.g. floodlamps) when checking the batteries. In case of doubt, remove the batteries and have them tested.  Assisted starting with batteries installed Connect first the positive terminal of the jumper cable to the batteries and then to the supplying unit.

Repair work HYDRAULIC SYSTEM Repair – Instructions Always depressurize the hydraulic system before removing 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 as soon as possible by new ones. Use original spare parts from CGM HMS. 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 – 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.



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.

BA RH40E(3 725 088.00)-EN

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.

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.
