Introduction ALL PRODUCTS FOREWORD Literature Information This manual should be read carefully before using this product for the first time and before performing maintenance. This manual should be stored in the product literature holder or in the product literature storage area. Immediately replace this manual if lost, damaged, or unreadable. This manual may contain safety information, operation instructions, transportation information, lubrication information, and maintenance information. Some photographs or illustrations in this publication show details or attachments that can be different from your product. Guards and covers might have been removed for illustrative purposes. Continuing improvement and advancement of product design might have caused changes to your product, which are not included in this publication.

Whenever a question arises regarding your product, or this publication, consult your dealer for the latest available information.

Safety The safety section, if present, lists basic safety precautions. In addition, this section identifies the text and locations of safety messages used on the product. Read and understand the basic precautions listed in the safety section before operating or performing lubrication, maintenance, and repair on this product.

Operation The operation section, if present, is a reference for the new operator and a refresher for the experienced operator. This section includes a discussion of gauges, switches, controls, attachment controls, transportation, and towing information (if applicable).

Photographs and illustrations guide the operator through correct procedures of checking, starting, operating, and stopping the product. Operating techniques outlined in this publication are basic. Skill and techniques develop as the operator gains knowledge of the product and its capabilities.

Product Information The product information section, if present, may provide specification data, product intended use, product identification plate locations, and certification information.

1-2

Maintenance The maintenance section, if present, is a guide to equipment care. Proper maintenance and repair are essential to keep the equipment and systems operating correctly. As the owner, you are responsible for the performance of the required maintenance listed in the Owner Manual, Operation and Maintenance Manual, and Service Manual. The Maintenance Interval Schedule lists the items to be maintained at a specific service interval. Items without specific intervals are listed under the "When Required" service interval.

The Maintenance Interval Schedule lists the page number for the step-by-step instructions required to accomplish the scheduled maintenance. Use the Maintenance Interval Schedule as an index or "one safe source" for all maintenance procedures.

Maintenance Intervals Use the service hour meter to determine servicing intervals. Calendar intervals shown (daily, weekly, monthly, etc.) can be used instead of service hour meter intervals if they provide more convenient servicing schedules and approximate the indicated service hour meter reading. Recommended service should always be performed at the interval that occurs first. Under extremely severe, dusty, or wet operating conditions, more frequent lubrication than is specified in the maintenance intervals chart might be necessary. Perform service on items at multiples of the original requirement. For example, at every 500 service hours or 3 months, also service those items listed under every 250 service hours or monthly and every 10 service hours or daily.

Product Capacity Additional attachments or modifications may exceed product design capacity, which can adversely affect product performance characteristics, safety, reliability, and applicable certifications. Contact your dealer for further information.

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 CGMHMS GmbH Service.

CGM-HMS GmbH 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 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.

Introduction FIRE AND EXPLOSION HAZARD 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 on the safe handling of the fire extinguishers to be used.

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

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

Do not store or handle any flammable substances during operation.

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

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

Even battery gases can ignite in open flames or fire.

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

open or smouldering fire may occur.

Remove the hydraulic shovel from such an area where combustible or easily flammable liquids have spilled from the hydraulic shovel 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 hydraulic shovel.

1-16

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

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

If necessary, also cover the ground with fireprotective blankets.

Ensure sufficient ventilation.

Clean the hydraulic shovel 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.

DANGER TO LIFE Call the fire brigade.

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

OPeration FIRE AND EXPLOSION HAZARD Safety instructions Avoid smoking and open fire on, next to and below the machine.

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

Do not store such substances on the hydraulic shovel.

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

Such substances may spontaneously ignite if they get into the vicinity of hot units.

Even battery gases can ignite in open flames or fire.

Avoid parking the hydraulic shovel in places where – combustible substances such as coal dust or tar are present, – open or smouldering fire may occur.

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

Flying sparks may cause fire on the ground that can spread to the hydraulic shovel.

OPeration Undercarriage The undercarriage of the hydraulic hydraulic shovel 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.

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

Drive unit The drive unit comprises electric motor, pump drive gearboxes, hydraulic pumps, hydraulic cylinders and hydraulic motors.

Hydraulic system All working and travelling movements are performed hydraulically. The movements are controlled by servovalves. The working commands are initiated by hand and transmitted to the valves via control circuits. The oil supply from the superstructure to the undercarriage is ensured by the rotor. The hydraulic system is overload-protected by pressurerelief valves. The hydraulic pumps are supplied with oil from a hydraulic reservoir.

2-8

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

Four interconnected electronic units ensure optimal use of the installed electric motor 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 electric motor 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 electro-hydraulic valves which control the execution of the working movements.

EM029999-0

OMM 6060AC, 6060ACFS(3 847 043.00)-EN

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

These special features offer the following advantages:  minimum power losses, 

reduced temperature of the hydraulic oil,



greater service life of hydraulic pumps and electric motor.

Board-Control-System (BCS) The BCS is a micro-processor-controlled system for the acquisition and processing of measuring data.

It's function consists in collecting data of the hydraulic shovel operating conditions and to evaluate, store and display these data to the hydraulic shovel operator. 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 drive of stored data and software updating.

The measured values (actual values) from the sensors and transducers installed in the hydraulic shovel 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 other electronic units are acquired, processed and displayed in the same way.

Critical states of operation are brought to the operator'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 hydraulic shovel operator 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"

Time-out before restart

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

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

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

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

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

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

The BCS3e system prohibits switching on the electric motor until it is cooled down.

The BCS monitor (Fig. 2-90:) displayes the remaining time until the time-out period is over.

To avoid straining the vacuum contactor, the electric motor should be shut down only when load-free, i.e. without any of the hydraulic units being activated at the same time via the control valve.  Actuate switch-key (42, Fig. 2-89:).

The relay monitors the operating conditions of the electric motor and protects the motor against faults in the electrical system of the motor Depending on the nature of the fault, the motor protection relay switches off  the power supply of the motor via the vacuum contactor or 

the power supply of the machine via the switch-disconnector.

At the factory, the motor protection relay is programmed for the following functions:  protection against overcurrents,

Fig. 2-94:



protection against overloading,



detection of ground faults,



temperature monitoring,



restart inhibit,



protection against undervoltage,



OPeration Active-power transducer - Function

Fig. 2-96:

The electrical system of this machine is equipped with an active-power transducer. The transducer is located in the 400 V switch cabinet (arrow, Fig. 2-96:).

The active-power transducer measures permanently the currents, voltages and phase angles in the system and derives the active power (P) the apparent power (S) and the reactive power (Q) from these values. All these measured values can be displayed on the screen.

The active-power value is used to generate an analog signal (4-20 mA). This signal is used to monitor the tilting angle of the hydraulic pumps. In combination with the Pump Management System (PMS), any overloading of the electric motor due to an excessive demand of hydraulic power is thus avoided.

The device is factory-programmed in such a way that all relevant measured values can be displayed in four screens on the monitor (1, Fig. 2-97:). The different screens are selected with the keys (3).

Screen 1 displays the numeric values of:  the voltages of phases L1, L2 and L3 and the total current.

Screen 2 displays the numeric values of:  the active-power (P), the apparent power (S), the reactive power (Q) and the frequency.

Screen 3 displays a current / voltage diagram.

OPeration OPERATIONAL PRACTICES Working operation - Safety instructions

Personnel Any work with the machine must be executed only by reliable, skilled and well trained personnel in good healthy condition. Statutory minimum age limits must be observed.

Never operate the machine while impared with drugs or alcohol.

Read the sections "Fundamental safety instructions" and "Operation, safety instructions" in this Operation and Maintenance Manual carefully and observe the instructions given in this sections.

Observe all job site safety requirements.

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

Clear all obstacles from the path of the machine.

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 all persons have left the hazard range before resuming work.

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

When working or traveling on a slope is required, do not exceed the maximum machine inclination for working operation and for traveling (refer to Operation and Maintenance Manual section “Maximum machine inclinations”).

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.

As travel brakes are deactivated, the machine could slightly move in direction of excavating during operation. Whenever loading operation is interrupted, stand attachment on the ground. This avoids slight movement of the machine and possible consequential damage of lowered ladder, in case ignition remains engaged.

Adjust the operator’s seat for comfortable reach all controls and pedals. Adjust for operator height and weight.

Keep your workplace clean. Remove all unsecured items like tools and other supplies from the cab.

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.

Clean and secure all windows and doors.

Clean and adjust all mirrors for optimum vision.

Start the electric motor only from the operator’s compartment.

Operate the machine only while sitting on the operator’s seat.

State of the machine Operate the machine only if all protective and safety oriented devices, such as removable safety devices, emergency shut-off equipment, soundproofing elements and exhausters, are in place and fully functional.

Do not operate the machine,  when several track rollers or upper rollers have been removed;  when one or several swing 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".

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

OPeration Working operation – basics

Working on level ground

This section gives you basic information about the functions of the joystick controls. For further detailed information refer to section “Operation Techniques” in this Operation and Maintenance Manual:  “Machine operation with backhoe attachment Best Practices”,  “Machine operation with backhoe attachment – Restricted Operation”,  “Machine operation with face shovel attachment - Best Practices”,  “Machine operation with face shovel attachment – Restricted Operation”.

CGM HMS recommends operating the machine on level and stable ground. Doing so ensures maximum productivity and prevents machine components from premature wear.

Working on slopes or on rough terrain Clean and level rough terrain before moving into the bank. A clean, level pit floor is necessary for safe and stable machine operation and prevents the tracks and other components of the undercarriage from being damaged.

When working or traveling on a slope is required, do not exceed the maximum machine inclination for working operation and for traveling (refer to Operation and Maintenance Manual section “Maximum machine inclinations”).

If the machine begins to sideslip on a slope, immediately lower the attachment and the load to the ground and turn the machine facing downhill.

Operate the machine slowly, accelerate and decelerate attachment movements gently. Sudden movements with full speed and filled bucket are a huge strain for the structure which could tip the machine over.

When working on a slope, always operate the hydraulic shovel with the attachment positioned uphill or downhill, never sideways.

When traveling up and down a slope or when traveling over rough terrain reduce travel speed mode to slow (refer to Operation and Maintenance Manual section “Traveling”).

Operate joystick controls gently Accelerate and decelerate attachment movements gently. Sudden acceleration and abrupt braking with full speed and filled bucket are a huge strain for the structure.

Avoid aggressive operating practices. Do not overload the machine.

OPeration OPERATION TECHNIQUES Machine operation with backhoe attachment, Best Practices Machine Stability

When working with the attachment in a cross direction to the tracks, be sure that the track is not raised off the ground. This can cause the track to set-off from the rollers when it is lowered down on the ground.

Also the flanges of the track rollers and the track shoes can be bent by the excessive load.

Refer to Operation and Maintenance Manual, “Restricted Operation” for further detailed information.

Do not overfill / overload the bucket, the machine may tip over.

Fig. 2-116:

When working or traveling on a slope is required (Fig. 2-117:), do not exceed the maximum machine inclination for working operation and for traveling (refer to Operation and Maintenance Manual section “Maximum machine inclinations”).

Do not operate the shovel on rain-slicked, slippery slopes. The shovel may slip.

Clean and level the pit floor before moving into the bank. A clean, level pit floor is necessary for safe and stable machine operation and prevents the tracks and other components of the undercarriage from being damaged.

Position the hydraulic shovel on level, consistent, firm and stable ground.

The hydraulic shovel may gradually sink on soft and yielding ground. Always re-enforce soft and yielding ground with firm material.

Fig. 2-117:

The hydraulic shovel must always be operated in a way, that its stability is always ensured and the danger of tipping over is avoided.

Machine stability is greater when the bucket is parallel with the tracks (Fig. 2-116:).

When working with the bucket parallel to the tracks, the final drives should be in the rear position, for the following reasons:  The travel motors and final drives are protected from falling rocks etc. 

When the hydraulic shovel is operated on muddy ground and the tracks are covered with mud, the sprocket runs on a clean track when backing up.

If it is unavoidable to work on soft and yielding ground, operate the machine at reduced bucket loads to avoid tipping of the machine.

When working on high-density and coarse material, operate the machine at reduced bucket loads to avoid overloading and damaging components of the machine.

Stand attachment down to the ground during breaks in working operation.

Do not operate the hydraulic shovel in water or in mud deeper than the breather valves of the final drives. Refer to section “Restricted Operation”.

Fig. 2-120:

Fig. 2-121:

Sufficient bench height

A sufficient bench height is essential for efficient and safe operation.

The ideal bench height is equal to the stick length or equal to the truck body rail height (Fig. 2-122:).

Note: This is a rule of thumb and is valid only if the material allows this bench height and only for standard truck match.

OPeration Truck on lower level — drive-by loading (Fig. 2-126:): Advantage:  Truck spotting time is eliminated, for the highest productivity, because the next truck does not need to reverse for positioning.

Disadvantages:  More than 90° swing angle. 

Fig. 2-126:

Loading through the gate could be more difficult due to limited space for dumping.

Truck on upper level — top loading (Fig. 2-127:): Working with the hydraulic shovel and the truck on the same level offers the following improvements:  Loading over side walls offers reduced swing angle. 

Loading over tail offers reduced lifting effort for faster cycles.

This working technique is best applied for drop cuts and in difficult to access or wet areas at the pit bottom.

Disadvantages:  Increased lifting effort and larger swing angle requires longer cycle time.

OPeration Digging and Loading Loading Trucks, do:  Start at "key cut" and work toward the truck. 

Always work over the idler and swing no more than 60° to the truck.



Prepare the next cuts in advance.



General digging advance is backwards.



Maintain a proper bench height.



Position the truck close enough to the machine for effective loading, but not too close so that the machine cannot hit and damage the truck.



Most productive work is performed with the truck on a lower level.



Swing the attachment at a sufficient height over the loading platform.



Distribute material evenly on the truck bed.



Remove sticky material from the bucket.



Always keep the shovel as close as possible to the work area. This minimizes short stick and boom movements - high efficiency.



Correct bucket size and properly adjusted equipment prevents overloading and ensures maximum operating efficiency of the hydraulic shovel.

Loading Trucks, do not:  Do not swing the attachment over unprotected driver cabs. 

Do not overload the truck.



When turning into a pit, the swing motion must not be stopped by the walls of the pit. Doing so can cause structural damage to the attachment.

Use the machine hydraulic system to stop the swing motion.



Only a bucket with a complete set of teeth and cutting edges in good condition ensures efficient performance.



Loosen hard material and rocks with the bucket, not with the stick crowding thrust.



Avoid digging with corner tooth to avoid torsional forces into attachments.



Avoid contacting mechanical stops and cylinders end of stroke.

Use the following guidelines when digging and loading a truck (Fig. 2-128: and Fig. 2-129:):  Position the stick at an angle to the ground as shown in (Fig. 2-129:).  Position the bucket cutting edge at an angle to the ground as shown in (Fig. 2-129:). This allows maximum breakout force to be exerted throughout the dig cycle.  Move the stick towards the cab and keep the bucket parallel to the ground.  If the stick stops due to the load, raise the boom and / or perform a curl in order to adjust the depth of the cut.  To apply the greatest force at the cutting edge, decrease the down pressure as you move the stick toward the cab.  Maintain a bucket attitude that ensures a continuous flow of material into the bucket.  Continue the pass in a horizontal direction so that material peels into the bucket.  Curl in the bucket and raise the boom when the pass has been completed.  Swing the load from the rear of the truck or from the side of the truck. Never swing a load over a truck cab or personnel.  To dump a load, move the stick outward and open the bucket in a smooth motion.  Load trucks evenly. This will help to avoid overloading the rear axle.  When bucket is empty, swing the upper structure back and begin the next loading cycle.

OPeration Double Benching Double Benching is an operation method which could be productive but also be very harmful to component life. This method should be used only by well trained and experienced operators in accordance with the following rules.

Fig. 2-130:

Rules for “Double Benching” Material: Loose, well blasted and easy to dig material is absolutely essential for Double Benching.

Boom down function should be used in float position only to pull down material from the wall.

Note: Digging poorly blasted material with great boulders or too tough material is a great stress for the steel structure and could result in serious damages.

Do not use the “Power boom down” - function.

Always maintain a proper distance to the highwall to avoid operating at the limits of the cylinders.

Bench height: A high bench is split up into two segments, 1/3 of the bench is below the excavator and 2/3 is above the excavator (Fig. 2-130:).

The ideal upper bench height is when the bucket could lay flat on the top of the bench (1, Fig. 2-130:).

The ideal lower bench height is equal to the length of the stick or equal to the truck body side wall edge.

Note: Too low lower benches can cause collisions of the counterweight and the truck body.

Working direction: While digging the upper bench, the cab must be on the opposite side of the high wall, swing direction is to the truck / cabin side (Fig. 2-130:). Dig forward (arrow, Fig. 2-130:).

While digging the lower bench, the cab must be on the opposite side of the high wall, swing direction is to the truck / cabin side (Fig. 2-131:). Dig backwards (arrow, Fig. 2-131:).

Fig. 2-131:

Working method: Dig the upper bench first, progressing from right to left, by digging down material from the face (Fig. 2-130:).

Dig the lower bench on the way back in standard setup from left to right (Fig. 2-131:).

Dig a trench in front of the machine and along the high wall (2, Fig. 2-130:).

Leave this trench along the dig face (approx. 1.5 meters / 5 ft. deep) while digging forward.

If any spillage falls out it is collected in the trench and won’t damage the excavator.

The hole in front of the machine also eases bucket fill.

OPeration Grading the pit floor The described grading function can be performed precisely by simultaneously use of the boom, stick and bucket function.  Position the stick slightly forward of the vertical position with the bucket in the dumped position (Fig. 2-132:).  Operate the stick-retract function while slowly raising the boom. When the stick moves past the vertical position, slowly lower the boom to allow the bucket to maintain a smooth surface.

Fig. 2-132:

Park the Machine

Park the machine in a location that is smooth, stable, level and hard. The location should also be dry and free of debris and not endangered by falling rock. Bring the attachment in a position like shown in (Fig. 2-133:): - Half extend the boom cylinders.

- Bring the stick in a vertical position.

- Lower the boom until the bucket is on the ground.

Note: Other positions of the attachment are not allowed when parking the machine. Refer to section “Backhoe Operation - Restricted Operation”.

OPeration Machine operation with face shovel attachment - Best Practices Machine stability When working with the attachment in a cross direction to the tracks, be sure that the track is not raised off the ground. This can cause the track to set-off from the rollers when it is lowered down on the ground.

Also the flanges of the track rollers and the track shoes can be bent by the excessive load.

Refer to Operation and Maintenance Manual, “Restricted Operation” for further detailed information.

Do not overfill / overload the face shovel, the machine may tip over.

Fig. 2-134:

When working or traveling on a slope is required (Fig. 2-135:), do not exceed the maximum machine inclination for working operation and for traveling (refer to Operation and Maintenance Manual section “Maximum machine inclinations”).

Do not operate the shovel on rain-slicked, slippery slopes. The shovel may slip.

Clean and level the pit floor before moving into the bank. A clean, level pit floor is necessary for safe and stable machine operation and prevents the tracks and other components of the undercarriage from being damaged.

Position the hydraulic shovel on level and firm ground. The hydraulic shovel may gradually sink on soft ground. Always re-enforce soft ground with firm material.

Fig. 2-135:

The hydraulic shovel must always be operated in a way, that its stability is always ensured and the danger of tipping over is avoided.

Machine stability is greater when the bucket is parallel with the tracks (Fig. 2-134:).

When working with the bucket parallel to the tracks, the final drives should be in the rear position, for the following reasons:  The travel motors and final drives are protected from falling rocks etc. 

When working on soft ground or on high density material, operate the machine at reduced bucket loads.

Stand attachment down to the ground during breaks in working operation.

Do not operate the hydraulic shovel in water or in mud deeper than the breather valves of the final drives. Refer to section “Restricted Operation”.

When the hydraulic shovel is operated on muddy ground and the tracks are covered with mud, the sprocket runs on a clean track when backing up.

OPeration Bench Heights on Steep Slopes

Minimum Bench Height Hydraulic face shovels can work on low faces due to their kinematics.

The working face should be at least as high as the bucket itself for sufficient bucket fill. With the 6030, for example, it is about three meters (Fig. 2-138:).

Continuous high lifting effort and frequent relocation results in unproductive loading cycles.

Fig. 2-138:

Bench Height on Steep Slopes Example situation: The material to dig is e.g. free - dig overburden.

- Material characteristics is – sticky / in situ, - It is a steep slope - angle is approx. 60°.

The optimal bench height is for tough digging (Fig. 2-139:): - Cabin roof height (e.g. for 6030 FS): ~7m

Fig. 2-139:

The maximum bench height is (Fig. 2-140:): - 75% of the maximum vertical reach (e.g. for the 6030 FS): 13.9 m x 0.75 ≈ 10 m (These are rules of thumb, they are a guide only, values depend on the material conditions).



The undercarriage should be positioned at 45° to the face (Fig. 2-143: and Fig. 2-144:).



Sprocket / final drives shall always point away from the face.



Truck position on the left hand (cab) side of the shovel.



Shovel operator and truck driver have eye contact.



The 45° position towards the digging face allows quick escape in case of a face collapse (Fig. 2-144:).



All rollers are not exposed to damage.



Less dirt on RH from material falling from the face track.



The digging forces are transmitted lengthwise through the track pad grousers into the ground (Fig. 2-145:).



Traction is optimal in this position.



A crosswise position would apply side load to the rollers.

OPeration Recommended working direction Best practice is: Working from right to left (Fig. 2-146:).

Cleaning of the floor behind and beside the shovel is done by a dozer.

Trucks will drive on levelled and clean ground, this results in less tire / suspension damage.

Doing so is a clear separation of loading action and clean-up support.

The hydraulic shovel shall always return to the right end of the face (end of the cut) and start again.

Fig. 2-146:

Not recommended – Digging advance left to right Loading the truck to the left side means increased swing angle and longer cycle times (Fig. 2-147:) = unproductive.  The operator might try to reduce the swing angle, tails are left behind / no straight face. 

Truck position on rough ground / spillage, results in cleanup delays, dozer standby required, risk of tire damage.

Fig. 2-147:

Not recommended – Digging advance left to right Loading the truck to the right side (Fig. 2-148:) results in loading on the blind side.  Poor visibility of shovel operator to the truck means swing over the blind side. 

OPeration Loading setups

Single side loading The hydraulic shovel loads the trucks only on the left hand side (Fig. 2-149:). Truck driver and shovel operator have direct eye contact.

Single side loading with standard truck spotting is the best solution for most applications.

Advantages:  The hydraulic shovel can follow a straight working face without major repositioning effort.

Fig. 2-149:



Good floor conditions that are easy to maintain.



Support equipment can clean the excavated area behind the shovel without interfering with the loading action.

The face should always be mined from right to left, then travel back and continue.

The tracks should be positioned 45º toward the face; travel motors to rear.

Double side loading The hydraulic shovel loads the trucks alternately on left and right hand side (Fig. 2-150:).

Double side loading with self spotting increases productivity only short term and only if perfectly executed. A long-term productivity advantage will not be achieved because of the many disadvantages and requirements.

Disadvantages:  Higher risk of collisions.

Fig. 2-150:



Well-trained operators are required.



While loading to the right side, both shovel operator and truck driver are on the blind side.



Shovel cannot follow straight working face and has higher repositioning effort.



Permanent clean-up support required.

The tracks should be positioned 90º toward the face; travel motors to rear.

Drop cuts are difficult but possible (Fig. 2-165:).  Drop cuts are uncomfortable for the operator due to working on an inclination.  Slewing uphill puts stress on components.  The operator has to be careful while slewing downhill because of additional acceleration and operate the machine slowly.  The maximum working inclination for CGM HMS Shovels is 8.7%, this is less than the recommended haul road grade of 10%.

Procede as follows: Maintain 8.7% with the CGM HMS Shovel and put to final 10% grade with a track type tractor.  For building of ramps, the values specified may be exceeded. In this case, however, a reduced service life of the components can be expected.

Drop cut = Digging down from current level to the next level down, creating a ramp in the process. 

OPeration Traveling – Best Practices

When traveling down from a steep bench (Fig. 2-237:), lower the bucket so that the distance to ground is about 0.5 m to 1 m (about 2 ft. to 3 ft.).

Travel slowly and in the lower gear mode.

In case the machine tends to tip to the front, lower the attachment to ground and protect the machine from tipping over.

Fig. 2-237:

When crossing the sharp edge of a steep bench upwards or downwards, travel very slowly and let the machine tip over the edge very carefully. Doing so prevents the machine from being damaged when impact on the ground (Fig. 2-238:).

Fig. 2-238:

Traveling in mud and water When traveling through any body of water or mud be careful that the level of water or mud is not higher than the breather valves on top of the final drives (Dimension A, Fig. 2-239:).

Water or mud could enter the gearboxes and cause serious damages.

While you cross any body of water or mud, carefully confirm the depth of the water or mud with the bucket. Do not move the machine into an area that has a water or mud depth that is higher than the breather valves of the final drives (Dimension A, Fig. 2-239:).

OPeration Traveling – Restricted Operation

Do not travel the machine longer than 5 minutes with the final drives to the front (Fig. 2-240:).

This will reduce the durability of the undercarriage and the travel system components.

Fig. 2-240:

Do not travel with a filled bucket (Fig. 2-241:).

Fig. 2-241:

Fig. 2-242:

2-134

If traveling down from a steep bench, do not place the bucket on the ground in order to prevent the machine from slipping or tipping (Fig. 2-242:).

The weight of the machine will force the stick cylinders and the bucket curl cylinders over the relief valves causing them to extend into their end stops.

The weight and inertia of the machine pressing on the cylinder – this could lead to overstressing cylinder clevis bolts.

Do not travel too steep ramps. Doing so can exceed the hydraulic capability of the machine. This can cause an uncontrolled state and damage to the machine. Refer to Operation and Maintenance Manual, section “Maximum Machine Inclinations” for information about maximum inclinations.

OMM 6060AC, 6060ACFS(3 847 043.00)-EN

OPeration

Always ascend the slope at a 90 degree angle (Fig. 2-243:).

Driving across the face of a slope or steering on a slope may cause the machine to slide or tip over.

Fig. 2-243:

Driving across the face of a slope or steering on a slope (Fig. 2-244:) may cause the machine to slide or tip over.

If the direction must be changed, move the machine to level ground, then, change the direction to ensure safe operation.

Fig. 2-244:

Do not travel through loose gravel material which could penetrate between rollers and track (Fig. 2-245:). This could result in damaging components of the under carriage.

Tracks may point load on rocks making the machine less stable.

OMM 6060AC, 6060ACFS(3 847 043.00)-EN

OPeration

Do not operate the machine in FAST travel speed unless in appropriate situations (Fig. 2-246:).

Refer to the “Travel Speed – Recommendations – Table“ for further details.

Fig. 2-246:

Do not travel over large rocks or unblasted material. Large rocks can damage components of the under carriage (Fig. 2-247:).

Fig. 2-247:

Do not use the force of the bucket, the stick or the boom to lift and assist in turning the machine while the machine is traveling (Fig. 2-248:).

This technique is referred to as “jump steering”.

Doing so creates the risk of high stress and damage to:  Swing ring and mounting bolts. 

Bucket or shovel front clam and back wall.



Undercarriage components.

For more information about correct turning the machine refer to section “Turning”.

OMM 6060AC, 6060ACFS(3 847 043.00)-EN

OPeration Maximum Machine Inclinations The machine must not exceed the inclinations indicated for working, traveling and servicing operations and during downtimes. The values specified in the tables below (next page) are valid for all types of attachment.

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

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

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

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

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

Maximum machine inclinations during working operations:

forward inclination

rearward inclination

side inclination

5° / 8.7%

Inspection and servicing Handling flammable liquids

Visible oil losses

When handling flammable liquids:  never smoke,

Have any visible leakage repaired immediately.

Escaping oil is an environmental hazard.

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

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



keep away from unshielded light sources and naked flames,

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

Use:  dry powder, 

carbon dioxide or



foam extinguishers.

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.

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

Never set foot withing reach of the emerging oil jet.

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

Used oil may be harmful to the skin.

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

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

Relieving residual pressure in the hydraulic system 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 electric motor 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.

Residual pressure is reduced only gradually. If an intervention into the hydraulic system is to be undertaken immediately after stopping, the system must be depressurized: (Do not leave the operator’s seat)  Stand attachment on the ground,  Switch off the electric motor,  Move all control levers and pedals repeatedly into all directions.

For more detailed information on depressurizing hydraulic sections please refer to the Service Manual, chapter 8.

Bolted connections, piping, hydraulic hoses Repair any leakage in the piping and hose system immediately.

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

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

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

Never repair damaged piping; always replace them.

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

Tighten leaking screw plugs only when the system is depressurized.

Escaping oil is an environmental hazard.

Inspection and servicing Non-polluting disposal

Handling batteries

Dispose of oils, lubricants, 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.

Batteries give off explosive gases.

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

Battery acid is toxic and corrosive.

Do not dispose of these substances together with household wastes.

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

Fill these substances into the containers provided for such purposes.

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

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

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

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

Sealing elements After replacing parts or after opening housings replace seals.

Always use new seals and gaskets.

Clean sealing faces prior to assembly.

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

When assembling, ensure a perfect fit.

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

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

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

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

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

Disconnect first the negative and then the positive terminal.

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

Inspection and servicing Selecting oils and lubricants

Oil-level check and oil change

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

Position the machine horizontally.

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

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 components and the hydraulic units.

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 lubricant film.

On completing work, re-install all protective devices.

Never switch on the electric motor while work is being done on the machine.

Carry out performance tests with the machine.

Inspection and servicing FIRE AND EXPLOSION HAZARD Safety Instructions Avoid smoking and open fire on, next to and below the machine.

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

Do not store such substances on the hydraulic shovel.

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

Such substances may spontaneously ignite if they get into the vicinity of hot units.

Even battery gases can ignite in open flames or fire.

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

open or smouldering fire may occur.

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

Flying sparks may cause fire on the ground that can spread to the hydraulic shovel.

Inspection and servicing INSPECTION AND SERVICING PLANS – INSTRUCTIONS Servicing Intervals The inspection and servicing plan lists all jobs which have to be done on the machine at regular intervals.

The individual inspection and servicing plans are marked with letters providing a link between the operating hours (OH) recorded by the hours-run meter of the machine and the inspection and servicing plans.

Plan V N

T

Do all jobs …. …once prior to initial commissioning. …after initial commissioning and during the running-in period (after 100 OH). …every 10 OH or every working shift 1)

…every 60 OH or weekly .2 W …after every 500 OH. B …after every 1000 OH. C …after every 5000 OH. D …after every 10000 OH. E OH = Bh = Operating hours

Oils / Lubricants For the specification of oils and lubricants to be used refer to the “LUBRICANTS / CONSUMABLES” section.

The numerals mentioned in the “Oil / Lubricant” column in the inspection and servicing plans have the following meaning: I II IIIa, b V

Inspection and servicing LUBRICANTS Notes on the selection of oils and lubricants Original CGM-HMS GmbH oils and lubricants Besides regular and careful maintenance, the quality of the oils and lubricants 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 lubricants that are approved for use in CGM-HMS GmbH machines. These oils and lubricants are especially adapted to CGMHMS GmbH machines and their units and assemblies.

Other oils and lubricants 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 lubricants.

All other qualities are not approved.

CGM-HMS Hydraulic Fluid Caterpillar is not in a position to evaluate the many types of fluids promoted by other manufactures and their effect on Caterpillar products. The use of these products is at the discretion of the customer who assumes all risks for the effects that result from this usage.

The CGM-HMS Hydraulic fluid that is provided as a factory fill for the HMS has been evaluated for fluid compatibility when adding or topping off with the Caterpillar HYDO Advanced product. The 2 fluids are compatible and can be used. Follow the maintenance interval schedule and for fluid sampling that is stated in the Operation and Maintenance Manual for your machine. To have the full benefit of the properties of either fluid the cross contamination should be kept to 10% or less. With a greater cross contamination the full benefit of either of the fluids may not be realized so it is important to monitor the fluid properties regularly. For additional details about Cat HYDO Advanced and Caterpillar’s fluids recommendations, please refer to Special Publication SEBU6250, “Caterpillar Machine Fluids Recommendations” and publication EM027744, “Fluid Specifications HMS” which may be found on the Web at SIS.Cat.com.

Although the lab testing has shown compatibility between the BM Hydraulic fluid and the Cat Hydo Advance, we are not able to test every situation and condition with the fluid mixtures and would recommend that the fluid be changed out to eliminate any fluid incompatibility issues.

Alternative oils and lubricants The oils and lubricants 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 lubricants that are not compatible with CGM-HMS GmbH specifications, CGM-HMS GmbH does not assume any responsibility and does not accept any warranty claims.

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

The the swing gearboxes are equipped with automatic drain valves (1, Fig. 3-10:) These automatic drain valves permit oil 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 (Fig. 3-9:).

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. 3-9:

Inspection and servicing Electric motor (SIEMENS) - Lubricate Risk of serious injury or death.

During lubricating the bearings the electric motor must be switched on.

Be extremely careful to all rotating parts.

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

Wear protective gloves and closefitting, firm work clothes.

Read and observe: "Inspection and Servicing – Safety Instructions" and the electric motor Operation and Maintenance Manual.

Lubricate the bearings of the electric motor in regular intervals (see plates on the electric motor, sample is shown in Fig. 3-13:) but every 12 months at the latest.

In the case of unfavorable operating conditions, the regreasing intervals must be reduced after consultation with the manufacturer.  Clean the grease nipples before lubricating.  Start machine and have motor idling.  Press in the correct quantity of lubricant specified on plate (Fig. 3-13:).  The used grease collects outside each bearing in a spent grease chamber.  When the electric motor is at standstill, remove the old, used lubricant from the grease chamber.

Up to 30 minutes after greasing the temperature of the bearings might heavily increase. Thereafter the temperature decrease to normal. This is normal, the procedure is monitored on the BCS display.

Lubricating roller bearings prior to commissioning (Initial Lubrication) When properly stored prior to commissioning for a longer period of time, normally the grease in the bearings does not deteriorate within two years.

Please note the information regarding long-term storage.

When commissioning, the bearings must be relubricated with twice the amount of lubricating grease. When doing this, the shaft must rotate so that the grease is replaced in the bearings.

3-38

Fig. 3-13:

Removing spent grease If the specifications on the lubricant plate are observed, the spent grease chamber will provide capacity for a calculated service life of at least 40 000 operating hours, approx. five years. When the spent grease chamber is full, the spent grease must be removed prior to relubrication. This is indicated by the fact that during relubrication, oil or grease escapes at the bearing cover.

Note: If the spent grease is not removed, then the roller bearings become too hot and can seize up as the grease distribution mechanism is disturbed.  To remove the spent grease, loosen the outer bearing cap.

Floodlights working with LED-technology do not have replaceable lamps / bulbs. The floodlight must be replaced if defective.

OMM 6060AC, 6060ACFS(3 847 043.00)-EN

Inspection and servicing Xenon floodlight projector (if equipped), replacing the lamp Safety instructions The floodlight projectors use xenon technology.

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

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

Warning!

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

if the projector housing is opened in an inapropriate way or



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

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

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

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

Wear googles and safety gloves when replacing the lamp.

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

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

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

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

Further instructions Always hold the xenon lamp by the base. Never touch the glass bulb. Sweat and lubricant 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. 3-29) as well as the working floodlights (Fig. 3-30) 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.

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

Fig. 3-29

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.

Inspection and servicing HYDRAULIC SYSTEM Hydraulic system - Safety instructions Read and observe the "Inspection and servicing – Safety instructions" chapter.

Switch off the electric motor.

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

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

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

Wait until the hydraulic system is cooled down to moderate temperature before starting work.

Contact with hydraulic oil can cause skin injury.

Avoid skin contact with hydraulic oil.

Wear protective gloves and firm working clothing.

Depressurizing the hydraulic system Hydraulic systems may only be opened if they are completely depressurized. Even when an hydraulic shovel is parked on a horizontal surface with the attachment resting on the ground (Fig. 3-31: and Fig. 3-32:) and with its electric motor switched off, 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:

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

3-62

Avoid mixing of different hydraulic fluids The machine has been run in at the factory with CM Long Term Hydraulic Fluid HSS (Part-No. 4211882). 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 CM 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 CM 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 Venting the hydraulic system Hydraulic pumps, hydraulic motors, hydraulic cylinders, travel brake valves, suction lines of hydraulic pumps, oil cooler manifolds and the servo control system must be vented  after assembly on site and prior to initial commissioning, 

before each recommissioning of the hydraulic shovel, e.g. after extensive repair work to the hydraulic system or after prolonged downtimes,



after each hydraulic oil change,



after replacement of hoses or lines.

Venting the hydraulic components 

Hydraulic pumps and hydraulic motors (with electric motors shut off).

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

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

Fig. 3-67:

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. 3-66: and Fig. 3-67:) must be either completely retracted or completely extended.

Fig. 3-66:

3-66

Always admit oil first to that side of the cylinder where the piston (2) is. This is  the piston-side port (3) when the piston rod is retracted (1, Fig. 3-66:),  the rod-side port (4) when the piston rod is extended (1, Fig. 3-67:).

If, for assembly reasons, the piston rod is inmiddle position, admit oil first to the pistonside 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.

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),



the intake line at the venting screw (with drive motors stationary).

The pressure accumulator (1) is located in the upper structure and is accessible from the ground.

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 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:

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

Group

II p  l bar and p·x l  200

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.

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".

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:

Repair work FIRE AND EXPLOSION HAZARD Safety Instructions Prior to commencing work, inform on the national and corporate rules for prevention of accidents. Pay particular attention to hazards caused by combustible and easily flammable substances. on the safe handling of the fire extinguishers to be used.

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

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

Do not store or handle any flammable substances during operation.

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

Such substances may spontaneously ignite if they get into the vicinity of hot units.

Even battery gases can ignite in open flames or fire.

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

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

Place suitable fire guardings (fire barriers) if open fire or flying sparks cannot be avoided during repair work. Apply special protection to cables, cable ducts as well as to hose and pipe lines.

If necessary, also cover the ground with fireprotective blankets.

Ensure sufficient ventilation.

Clean the hydraulic shovel 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.

open or smouldering fire may occur.

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

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

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

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

Use original spare parts from 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.

4-6

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

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

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

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

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

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

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



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



Leaks.



Non-observance of fitting requirements.



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



Detachment of the hose from the fitting.



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

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

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

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

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

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

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.

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

4-8

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.

OMM 6060AC, 6060ACFS(3 847 043.00)-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.

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.

The operator'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.

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

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.

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.

4-10

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

For problems or queries please contact the competent service personnel.

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

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.

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.  Fuel system: fuel tanks, fuel filters, fuel lines, filling station.

Auxiliary attachment and units, such as an onboard crane or an auxiliary heater have their own fuel tanks with the corresponding line systems.  Hydraulic oil: hydraulic oil reservoir, hydraulic cylinders, hydraulic motors, hosepipes, piping, hydraulic pumps, hydraulic valves, hydraulic oil filter, filling station.  Engine coolant: engine, radiator, expansion reservoir, piping and hosepipes, filling station.  Gearbox oil in slewing, travelling and drive gearbox systems, expansion tanks, piping and hospipes, filling station; idlers, support and track rollers.  Have the refrigerant (R134A) sucked out of the air conditioner system.  Grease from the central lubricating system, grease drum, piping and hosepipes, distributors, filling station; grease accumulations in bearings of the working equipment, grease filling in the slewing ring, grease filling in track and support rollers as well as in idlers.

Annex BOARD-CONTROL-SYSTEM BCS3e, what’s that?

What it is The BCS3e 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 shovels from CGM HMS GmbH. The BCS3e communicates with other electronic units in the shovel 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 BCS3e are located in cabinets in the module below the operator’s cab, the pump compartment and the electric motor compartment.

The exchange of data between sensors, controllers, the BCS3e 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 shovel 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 shovel'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 the electric motor 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 shovel constantly transmit their readings to the controllers of the CAMP system.

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

Fig. 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 operator’s cab (Fig. 1) – integrates the computer, the monitor, the control elements and the interfaces.

SIL2 functionality Safety related functions on the machine have been checked to minimize the risk of faults in their own function. Tests were performed according to the standards of functional safety (ISO 61508).

To fulfill the requirements for reaching the Safety Integrated Level 2 (SIL2) new components and electronic units had to be used on the machine.

These components and units are servo-controllers, sensors, switches, hand levers (joysticks), foot pedals and valves.

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 BCS3e, the Start Screen The screen displays the graphical user interface of the Board Control System. The basic screen (Fig. 3) appears when all electronic units of the CAMP system have started and when their self-tests 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.

Note: Never use pointed objects such as a ball pen, screwdriver, nail or similar to touch the screen.

This could damage the active surface of the touchscreen.

Do not press on the sensitive areas, just slightly touch them with your fingertips!

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
