OPERATING INSTRUCTIONS RH 400 Undercarriage

Stored Program Control (SPC)

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

The SPC controls the functions - Engine Start - Engine Stop - Engine Idle - Central lubricating system

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

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

Hydraulic system All working and travelling movements are performed hydraulically. The movements are controlled by servovalves. The working commands are initiated by hand and transmitted to the valves via electronic 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)

- Further auxiliary functions Further information is given in the technical manual:Stored-program control.

Electronic Hydraulic Servo-Control (EHSC) The EHSC is an electrohydraulic servocontrol.

Together with the PMS, it provides for optimum interaction between drive hydraulic circuit and working movements.

The required working movements are recognized by microcontroller-assisted scanning of the operating elements (hand levers, pedals) and transmitted to electrohydraulic valves.

In the system sequence, the drive regulation is first activated to provide hydraulic working energy.

Only then are working movements enabled.

Further information is given in the technical manual: Electronic Hydraulic Servo-Control.

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

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

20

2 731 030.03 en

OPERATING INSTRUCTIONS RH 400 Demand control / Zero-flow regulation

Board Control System (BCS)

In the fine-control range, swivelling of the hydraulic pumps, and thus variation of the oil flow, are proportional to control lever and pedal valve travel. This means that, during 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 zero flow.

The BCS is a data-evaluating and data-processing system whose function is to collect, evaluate and store data about the excavator’s operating status and to display these to the operator.

These special features offer the following advantages: • reduced fuel consumption • minimum power losses • reduced temperature of the hydraulic oil • greater service life of hydraulic pumps and diesel engines

Automatic engine speed reduction If the control pedal and control levers and thus the servovalves are not actuated for a period of 10 seconds or more (programmable), the engine speed is automatically reduced to idling. This function is a further contribution to fuel economy.

2 731 030.03 en

The BCS is based on a microprocessor. The measured values (actual values) supplied by sensors and transducers installed in the excavator are compared with preset nominal values. Outof-limit conditions are display in the form of error messages in the driver’s cab.

Critical operating conditions are additionally indicated by optical and acoustic warning signals.

Further details are set out in the Board Control System operating instructions.

Electrical system The electrical system operates on 24 volts.

The voltage for the floodlamps and the warmingup system is 110 V AC, 60 Hz (3-phase).

Escaping oil is an environmental hazard.

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

Never dispose of these substances together with household waste.

Dispose of these substances in the containers provided for such purposes.

Like any other oil, biodegradable, "environmentally friendly" hydraulic oil must be disposed of separately.

Never allow oils and oily waste to penetrate into the soil or into water. They are an environmental hazard.

Seals

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

Individual spares may contain asbestos. Such spares or their packaging are marked . with:

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

Never process spares containing asbestos mechanically. Inhaling asbestos dust is a health hazard.

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

Clean sealing surfaces prior to assembly.

Never repair damaged piping; always replace it.

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

Engine exhaust gases Exhaust gases are a health hazard; never inhale them.

When working on enclosed premises, draw off exhaust gases with a suction plant and ventilate the premises well.

OPERATING INSTRUCTIONS RH 400 Handling batteries

Selecting oils and greases

Batteries give off explosive gases.

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

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

Battery acid is toxic and corrosive.

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

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

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

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

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

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

Dispose of used batteries separately from other waste without polluting the environment.

Prior to work on the electrical system Prior to any work on the electrical system involving tools, spares, etc. coming into contact with electric cables or contacts, switch off the battery main switches.

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

All filters are coordinated carefully with the equipment. Original O&K parts must be used to ensure smooth running and a long service life of the engines and the hydraulic units.

Sealing elements When dismantling parts, watch for sealing elements.

Check sealing elements prior to installation, replacing any that are even slightly damaged.

When assembling, ensure a perfect fit.

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

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

Lubricating Clean the lubricating nipples, then lubricate as scheduled.

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

On completing work, re-install all protective devices.

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

Carry out performance tests with the machine.

OPERATING INSTRUCTIONS RH 400 Fire and Explosion Hazard

2796685

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 excavator.

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.

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

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

Intervals

Air-intake system

The inspection and servicing plan lists all jobs which have to be done on the machine at regular intervals.

The air filter must be serviced only if the BCS so indicates. Replace the filter elements after one year at the latest.

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

Do all jobs ....

Oils / Greases For the specification of oils and greases to be used, refer to the "Lubricants" section.

The numerals in the "Oil / Grease" column of the inspection and servicing plans have the following meaning: I

Oils for combustion engines and compressors

II

Oils for hydraulic systems

III

Oils for gearboxes

V

Greases for bearings and slewing rings

Cleaning jobs Cleaning jobs, especially on cooling systems, must be done at shorter intervals if the machine is exposed to severe dust build-up.

Whichever comes first.

OH = Bh = Operating hours

Change of engine oil The intervals stated for changing the engine oil apply to fuels with a sulphur content of < _ 0.5% and a permanent ambient temperature down to -10oC. In cases of a higher sulphur content and/or a permanent ambient temperature of below -10oC, shorter intervals are required.

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

Hose line for oil and coolant changes Collect escaping oil and coolant and discard without polluting the environment.

The hydraulic tank and the slewing gearboxes are moreover equipped with special drain valves (1, Fig. 2).

These 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 can be done by means of a hose through the service station (tank lift) (Fig. 1).

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 overpressure, whereas the draining operations require low pressure.

Fig. 2

Change the oil as follows: - Place a collecting recipient for used oil under the corresponding drain valve. For the recipient capacity, refer to the "Refilling quantities - Oil" table.

- Unscrew protective cap from drain valve.

- Screw on hose line (2) to open the valve, so that the oil can flow out.

- When the oil has drained out, unscrew the hose line to allow the valve to close automatically.

OPERATING INSTRUCTIONS RH 400 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 excavator, e.g. after extensive repair work to the hydraulic system or after prolonged downtimes • after each hydraulic oil change • after replacement of any hoses or lines.

Fig. 38

Venting the hydraulic components

Always admit oil first to that side of the cylinder where the piston (2) is. This is

- Hydraulic pumps and hydraulic motors (with the engines stationary).

•

the piston-side port (3) when the piston rod is retracted (1, Fig. 37)

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

•

the rod-side port (4) when the piston rod is extended (1, Fig. 38).

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

- 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, Figs. 37 and 38) must be either completely retracted or completely extended.

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

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

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

- the travel brake valve at the venting screw - the oil cooler manifold at the mini-measuring ports - the servo system at the venting screws of the control blocks (under the servo caps) - the intake line at the venting screw (with the drive engines stationary).

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

Extract from the German acceptance regulations Hydraulic accumulators are pressure vessels and are therefore subject to the "Druckbehälterverordnung (DruckbehV)" [Pressure Vessel Regulations]. Their installation, equipment and operation are governed by the "Technische Regeln Druckbehälter (TRB)" [Technical Rules for Pressure Vessels]. The pressure vessels of hydraulic accumulators are classified by the admissible operating pressure p in bars, the capacity l in liters and the product of pressure and capacity p x l. Depending on the class to which the accumulator belongs, the following inspections are mandatory:

Checking the gas charging pressure in the pressure accumulator

Fig. 40

Pressure-accumulator inspection regulations 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.

For measuring the precharge pressure in the pressure accumulator, observe the instructions set out in the booklet "Filling and testing device for pressure accumulators" annexed to this documentation.

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.

OPERATING INSTRUCTIONS RH 400 Technical data Track tensioning pressure ca. 60 bars Pressure limiting valve 400 bars Gas pressure in pressure accumulator (nitrogen filling pressure) 48 bars

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

Function The tensioning system is under a permanent pressure of ca. 60 bars which keeps both tracks permanently tensioned. Pressure losses are compensated as soon as the engines have been started up. Retensioning is not required.

The tracks can be slackened for cleaning or repair work.

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.

To do so: • stop the engines • open both pressure limiting valves (7, Fig. 6) to slacken the tracks.

• When work is finished, screw down the pressure limiting valves (7) to the limit stop.

Fig. 6

The pressure limiting valves (7) are preset to a pressure of 400 bars and sealed in this position.

This lead seal must not be removed and the pressure setting of 400 bars must not be changed.

The stopcocks (10) are permanently open. They must not be closed except for dismantling of the pressure accumulators (5).

For the rest, the track tensioner is maintenancefree.

OPERATING INSTRUCTIONS RH 400

Extract from the German acceptance regulations Hydraulic accumulators are pressure vessels and are therefore subject to the "Druckbehälterverordnung (DruckbehV)" [Pressure Vessel Regulations]. Their installation, equipment and operation are governed by the "Technische Regeln Druckbehälter (TRB)" [Technical Rules for Pressure Vessels]. The pressure vessels of hydraulic accumulators are classified by the admissible operating pressure p in bars, the capacity l in liters and the product of pressure and capacity p x l. Depending on the class to which the accumulator belongs, the following inspections are mandatory:

Checking the gas charging pressure in the pressure accumulator After commissioning (new installation or repair), the gas charging pressure in the pressure vessel

Group IV p > l bar p˙l > 1000

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 pressure tests are required to ensure the efficient functioning of the track tensioner.

They are not a substitute for the inspections specified in 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. Cf. "Function".

For measuring the precharge pressure in the pressure accumulator, observe the instructions set out in the booklet "Filling and testing device for pressure accumulators" annexed to this documentation.

OPERATING INSTRUCTIONS RH 400 Checking the grease pressure Once a week, check that the oil pressure indicated by the pressure gauge (4, Fig. 7) is 28 - 30 bars.

This oil pressure is increased to 300 - 350 bars greasing pressure by a pressure intensifier.

If this is not the case, stop the engines and check the central lubricating system.

If the lubricating pressure is lower, not all greasing points are supplied with grease.

Unblocking a grease line Put the excavator back into operation only when the lubricating system is working properly and the unloaded working equipment has been actuated for ca. 5 min. This is necessary to ensure that sufficient grease is supplied to the cylinder bearings.

Cleaning the grease sieve Check the grease sieve at regular intervals for contamination; clean if necessary. The grease sieve must also be cleaned after an obstruction in one of the greasing points.

Cleaning • Loosen plug (5, Fig. 7).

• Withdraw sieve and clean with white spirit or paraffin oil.

• Re-insert sieve and fasten with plug (5).

Fig. 7

Higher greasing pressures may cause a greasing line to burst.

Always replace or refill the grease container in good time, as air otherwise penetrates into the lubricating system and causes trouble.

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.

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 fire-protective blankets.

Ensure sufficient ventilation.

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

Clean the excavator before starting a job.

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

Do not store or handle any flammable substances during operation.

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

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 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.

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

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 batterı́es as possible.

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

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

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

- Assisted starting with batteries installed Connect first the positive terminal of the jumper cable to the batteries and then to the supplying unit. 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) 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 order and disconnect after starting.

Fig. 1

Starting up the engines • Start up the engines of the supplying machine and run at high speed.

• Start up the engine of the receiving machine. If the engine fails to start up after 15 seconds, wait for one minute and then start again.

• 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 • Negative pole at the receiving machine (4)

• Switch off all consumers at the receiving machine and turn the key-operated switch to "0" .

• Switch off all consumers at the supplying machine (charged batteries) and shut off the engine.

Connecting the jumper cables • Connect the red jumper cable to the positive pole of the empty battery (1, Fig. 1), then to the positive pole of the charged battery (2).

• 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).

2 731 030.03 en

• Negative pole at the supplying machine (3) • Positive pole at the supplying machine (2) • Positive pole at the receiving machine (1) • 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 RH 400 HYDRAULIC SYSTEM

2413504

Repair Before disconnecting hydraulic hoses: depressurize the hydraulic system.

Replace damaged or leaking hydraulic hoses by new ones.

Use original O&K spare parts.

These parts are specially suitable for the respective function.

Do not re-use used hoses.

Dispose of spilt oil and oily wastes without polluting the environment.

These wastes must not be allowed to penetrate into the soil.

Hydraulic hoses should be replaced after a service life of 6 years.

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

Accumulators, safety instructions 2411963 Accumulators are installed in the hydraulic system. These accumulators contain nitrogen under high initial pressure.

Even when the hydraulic pressure in the system is reduced, the nitrogen remains in the accumulator.

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.

OPERATING INSTRUCTIONS RH 400 WELDING OPERATIONS Welding operations - Safety instructions Never perform welding operations unless you are qualified to do so.

Observe the accident prevention regulations.

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".

2462901

Prior to any welding operations on the machine: - Set battery main switch to OFF 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. distance 2 - 3 m).

The welding current must not flow via the ball or 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.

- Set battery main switch to ON

Should you have any problems or queries, apply to the O&K aftersales 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".

OPERATING INSTRUCTIONS RH 400 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 operating manual once again before rectifying any faults.

If you are unable to detect the cause of the fault or rectify it, apply to the O&K after-sales service.

2261173

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:

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

Never do any jobs for which you are not qualified.

This 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.

- 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?

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.

Remedial action This describes the troubleshooting procedure.

Section This specifies where information on troubleshooting is given in the operating manual. If there is no entry, the O&K after-sales service should be consulted.
