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

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

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

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

If necessary, also cover the ground with fireprotective blankets.

Ensure sufficient ventilation.

Clean the excavator before starting a job.

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

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

Do not extinguish flammable liquids with water.

Use:

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

§

dry-powder,

§

carbon-dioxide or

Do not store or handle any flammable substances during operation.

§

foam extinguishing compounds.

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

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.

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

Call the fire brigade.

Have all your welding, flame cutting and grinding work approved

Avoid parking the excavator in places where §

combustible substances such as coal dust or tar are present.

§

open or smouldering fire may occur.

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

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

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

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

Demand control / Zero-flow regulation In the fine-control range, swivelling of the hydraulic pumps, and thus the variation of oil flow, are proportional to control lever and pedal valve travel.

This means that during the work, the pumps supply only as much hydraulic oil as required to perform the working movement. In the neutral position of the control levers, the pumps are automatically swivelled to zeroflow.

Drive

These special features offer the following advantages:

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

§

reduced fuel consumption

§

minimum power losses

§

reduced temperature of the hydraulic oil

§

greater service life of hydraulic pumps and diesel engines.

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

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

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

Electrical system The electrical system operates on 24 volts

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

OPERATING INSTRUCTIONS Operation LIFTING OPERATIONS

Register the weight of the load. Sling only those loads not exceeding the load capacity of the lifting gear and of the machine

Safety instructions

Sling the load in such a way as to prevent it from slipping or falling while being lifted or transported.

Transporting the load Never use the machine for liftinggear operation unless it is equipped and approved for this purpose, i.e. the machine must be equipped with an overload warning system and a pipe break protection.

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

Switch the overload warning system on. (cf. "Technical data").

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

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

The built-in overload warning device cannot totally exclude accidents due to incorrect operation. This applies in particular to: §

inadequate hooking of the load or the loadcarrying device,

§

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

§

loads dropping into the cable,

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

§

oblique pull,

§

driving the excavator into an area with steeply sloping ground,

§

exposure to strong wind.

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

Avoid these risks by handling the machine carefully and with discretion.

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

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

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

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

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

BA RH30F(3 663 960.00)-EN

OPERATING INSTRUCTIONS RH 30 F Operation Load hook (optional equipment).

Read and observe "Lifting-gear operation - Safety instructions".

Switch on your overload warning system.

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

The overload warning system is basically composed of an electro-hydraulic switching unit triggering an optical and acoustic warning signal before the admissible load moment is reached (Fig. 2-68:).

Fig. 2-68: Fig. 2-67:

Lifting capacity of the load hook The maximum lifting capacity of the hook is indicated on the load hook (Fig. 2-67:).

Do not shut off the overload warning system when the warning signal is sounded.

The overload warning system must be on during lifting operations.

Lifting capacity of the excavator The admissible lifting capacity as a function of the working range is set out in the load table, see "Technical Data".

The overload warning system merely gives warning signals; it cannot prevent the excavator from overturning.

When the warning signal sounds: §

let down the load immediatel

§

shorten the working range or reduce the load.

In spite of the overload warning system, the operator is obliged to make sure beforehand that the load to be lifted does not exceed the excavator's lifting capacity.

The operator exceeds the admissible load moment if too heavy a load is being lifted with a large working range of the equipment (lifting capacity, see section "Lifting capacity of the excavator").

OPERATING INSTRUCTIONS RH 30 F Operation Pipe burst protection Do not perform any adjusting or repair work on the overload warning system.

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

Adjustments and repairs might lead to improper functioning or even to complete failure of the overload warning system.

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

When a hydraulic line has broken:

Putting the overload warning system out of operation If the machine is used exclusively for normal excavator work, the overload warning system must be deactivated with switch (56, Fig. 2-72:).

Ü Warn persons in the vicinity of the machine by sounding the signal horn.

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

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

This synthetic hydraulic fluid has been tested by Terex Germany and approved for application in Terex Germany machines.

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

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

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

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

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

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

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

3-10

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

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

See section: "Environmentally compatible hydraulic fluid, sampling"

Environmentally compatible hydraulic fluid, conversion

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

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

The fluid can be used repeatedly for flushing.

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

In exceptional cases, open only when the system and the operating sequence are precisely known and any special tools required are available.

The operating manual contains no information on this point.

Dismantling components Never do dismantling while the machine is at operating temperature.

Oils, greases, or coolants may have a high temperature and result in burning or scalding.

Leave time for the machine to cool down.

Before starting work, depressurize piping and hoses, cylinders, radiator, hydraulic tank and other systems or units.

Replace defective components in good time to prevent major damage.

Clean the defective component carefully before dismantling it.

Mark the dismantled parts in the correct sequence to faciliate re-assembly.

When dismantling the component, close off exposed hose and piping connections, exposed drill holes and housings carefully to prevent any dirt from penetrating.

Wear an approved safety harness; it must be equipped with fall arresters and safety cables.

OPERATING INSTRUCTIONS RH 30 F Repair work FIRE AND EXPLOSION HAZARD 2796687

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.

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

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

If necessary, also cover the ground with fireprotective blankets.

Ensure sufficient ventilation.

Clean the excavator before starting a job.

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

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

Do not store or handle any flammable substances during operation.

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

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 excavator in places where §

combustible substances such as coal dust or tar are present.

§

open or smouldering fire may occur.

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.

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

OPERATING INSTRUCTIONS RH 30 F Repair work ELECTRICAL SYSTEM 2441955

Assisted starting (with jumper cables) – Safety instructions

Keep any potential ignition sources, such as unshielded lights or burning cigarettes, away from the batteries. Battery gases are highly flammable. Explosion hazard.

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

Assisted starting (with jumper cables) Prior to assisted starting

Read and observe the section: "Assisted starting – Safety instructions".

Starting the engine with jumper cables (external batteries

Risk of injury from acid splashes and battery gases.

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

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

Do not switch on electrical consumers (e.g. floodlamps) when checking the batteries. In case of doubt, remove the batteries and have them tested.

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

§

Assisted starting with batteries installed Connect first the positive terminal of the jumper cable to the batteries and then to the supplying unit. Connect the negative terminals in the same order. After starting, disconnect the jumper cable in reverse order, i.e. first the negative terminal and then the positive terminal.

§

Assisted starting without batteries installed (only for engine trial run)

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

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

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

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

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

BA RH30F(3 663 960.00)-EN

Do not disconnect the starting aid when the engine is running.

After disconnecting, the alternator runs without batteries. §

Connect the jumper cable in the above- described order and disconnect after starting.

Ü Switch off all consumers at the receiving machine and turn the key-operated switch to "0" Ü Switch off all consumers at the supplying machine (charged batteries) and shut off the engine.

4-7

OPERATING INSTRUCTIONS Repair work Connecting the jumper cables Ü Connect the red jumper cable to the positive pole of the empty battery (1,Fig. 4-1:), then to the positive pole of the charged battery (2). Ü Connect the black jumper cable first to the negative pole of the charged battery (3), then to the negative pole of the empty battery (4).

Explosion hazard When the negative terminal is connected to ground, a strong current flows through the jumper cable.

The sparks produced in the contact area can ignite the gases emanating from the discharged battery.

The negative terminal must therefore be connected to ground at a place as far away from the discarged batteríes as possible.

Fig. 4-1:

Starting up the engines Ü Start up the engines of the supplying machine and run at high speed. Ü Start up the engine of the receiving machine.

If the engine fails to start up after 15 seconds, wait for one minute and thenstart again. Ü When the engine has started up, continue running both machines in no-load operation for about two or three minutes with the jumper cables still connected.

Disconnecting the jumper cables Ü Negative pole at the receiving machine (4) Ü Negative pole at the supplying machine (3) Ü Positive pole at the supplying machine (2) Ü Positive pole at the receiving machine (1) Ü For machines with electronic modules: - Run engine for about half an jour at low speed. The batteries are partially charged.

- Shut off engine - Make all electrical connections to the modules.

- Start up engine without jumper cables.

OPERATING INSTRUCTIONS Repair work PRESSURE ACCUMULATORS SAFETY INSTRUCTIONS 2411963

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: Ü Never handle accumulators mechanically, never weld or solder. Ü Testing and servicing work must be carried out by experts only. Ü Prior to any testing and servicing work, depressurize the hydraulic part of the system. Ü To dismantle the accumulator, always wear goggles and working gloves. Ü Fill accumulator with nitrogen only, never with compressed air or oxygen. Ü Report any defects or damage to the machine owner without delay. Ü 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

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

Observe the accident prevention regulations.

Wear protective clothing §

protective suit

§

protective gloves

§

face protection

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

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

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

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

On completion of the welding operation, restore all electrical connections.

Any work on receptacles that contain or have contained substances §

which are combustible or which encourage combustion,

§

which are susceptible to explosion,

§

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

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

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

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

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