INTRODUCTION

The policy of Atlas Copco is to provide the users oftheir equipment with safe, reliable and efficientproducts. Factors taken into account are amongothers:- the intended and predictable future use of the

products, and the environments in which they areexpected to operate,

- applicable rules, codes and regulations,- the expected useful product life, assuming proper

service and maintenance,- providing the manual with up-to-date

information.Before handling any product, take time to read therelevant instruction manual. Besides giving detailedoperating instructions, it also gives specificinformation about safety, preventive maintenance,etc.Keep the manual always at the unit location, easyaccessible to the operating personnel.See also the safety precautions of the engine andpossible other equipment, which are separately sentalong or are mentioned on the equipment or parts ofthe unit.These safety precautions are general and somestatements will therefore not always apply to aparticular unit.Only people that have the right skills should beallowed to operate, adjust, perform maintenance orrepair on Atlas Copco equipment.

It is the responsibility of management to appointoperators with the appropriate training and skill foreach category of job.Skill level 1: OperatorAn operator is trained in all aspects of operating theunit with the push-buttons, and is trained to know thesafety aspects.Skill level 2: Mechanical technicianA mechanical technician is trained to operate the unitthe same as the operator. In addition, the mechanicaltechnician is also trained to perform maintenance andrepair, as described in the instruction manual, and isallowed to change settings of the control and safetysystem. A mechanical technician does not work onlive electrical components.Skill level 3: Electrical technicianAn electrical technician is trained and has the samequalifications as both the operator and the mechanicaltechnician. In addition, the electrical technician maycarry out electrical repairs within the variousenclosures of the unit. This includes work on liveelectrical components.Skill level 4: Specialist from the manufacturerThis is a skilled specialist sent by the manufacturer orits agent to perform complex repairs or modificationsto the equipment.In general it is recommended that not more than twopeople operate the unit, more operators could lead tounsafe operating conditions.

Take necessary steps to keep unauthorized personsaway from the unit and eliminate all possible sourcesof danger at the unit.When handling, operating, overhauling and/orperforming maintenance or repair on Atlas Copcoequipment, the mechanics are expected to use safeengineering practices and to observe all relevant localsafety requirements and ordinances. The followinglist is a reminder of special safety directives andprecautions mainly applicable to Atlas Copcoequipment.These safety precautions apply to machineryprocessing or consuming air. Processing of any othergas requires additional safety precautions typical tothe application and are not included herein.Neglecting the safety precautions may endangerpeople as well as environment and machinery:- endanger people due to electrical, mechanical or

chemical influences,- endanger the environment due to leakage of oil,

solvents or other substances,- endanger the machinery due to function failures.All responsibility for any damage or injury resultingfrom neglecting these precautions or by non-observance of ordinary caution and due care requiredin handling, operating, maintenance or repair, also ifnot expressly mentioned in this instruction manual, isdisclaimed by Atlas Copco.

To be read attentively and acted accordingly before towing, lifting, operating, performingmaintenance or repairing the compressor.

The manufacturer does not accept any liability for anydamage arising from the use of non-original parts and

GENERAL SAFETY PRECAUTIONS 9 Care shall be taken to avoid damage to safetyvalves and other pressure-relief devices,- 8 -

for modifications, additions or conversions madewithout the manufacturers approval in writing.If any statement in this manual does not comply withlocal legislation, the stricter of the two shall beapplied.Statements in these safety precautions should not beinterpreted as suggestions, recommendations orinducements that it should be used in violation of anyapplicable laws or regulations.

1 The owner is responsible for maintaining the unitin a safe operating condition. Unit parts andaccessories must be replaced if missing orunsuitable for safe operation.

2 The supervisor, or the responsible person, shall atall times make sure that all instructions regardingmachinery and equipment operation andmaintenance are strictly followed and that themachines with all accessories and safety devices,as well as the consuming devices, are in goodrepair, free of abnormal wear or abuse, and arenot tampered with.

3 Whenever there is an indication or any suspicionthat an internal part of a machine is overheated,the machine shall be stopped but no inspectioncovers shall be opened before sufficient coolingtime has elapsed; this to avoid the risk ofspontaneous ignition of oil vapour when air isadmitted.

4 Normal ratings (pressures, temperatures, speeds,etc.) shall be durably marked.

5 Operate the unit only for the intended purpose andwithin its rated limits (pressure, temperature,speeds, etc.).

6 The machinery and equipment shall be kept clean,i.e. as free as possible from oil, dust or otherdeposits.

7 To prevent an increase in working temperature,inspect and clean heat transfer surfaces (coolerfins, intercoolers, water jackets, etc.) regularly.See the Preventive maintenance schedule.

8 All regulating and safety devices shall bemaintained with due care to ensure that theyfunction properly. They may not be put out ofaction.

especially to avoid plugging by paint, oil coke ordirt accumulation, which could interfere with thefunctioning of the device.

10 Pressure and temperature gauges shall be checkedregularly with regard to their accuracy. They shallbe replaced whenever outside acceptabletolerances.

11 Safety devices shall be tested as described in themaintenance schedule of the instruction manualto determine that they are in good operatingcondition. See the Preventive maintenanceschedule.

12 Mind the markings and information labels on theunit.

13 In the event the safety labels are damaged ordestroyed, they must be replaced to ensureoperator safety.

14 Keep the work area neet. Lack of order willincrease the risk of accidents.

15 When working on the unit, wear safety clothing.Depending on the kind of activities these are:safety glasses, ear protection, safety helmet(including visor), safety gloves, protectiveclothing, safety shoes. Do not wear the hair longand loose (protect long hair with a hairnet), orwear loose clothing or jewelry.

16 Take precautions against fire. Handle fuel, oil andanti-freeze with care because they areinflammable substances. Do not smoke orapproach with naked flame when handling suchsubstances. Keep a fire-extinguisher in thevicinity.

SAFETY DURING TRANSPORT AND INSTALLATION

- remove wheel chocks, if applied, anddisengage the parking brake.

hoists, each at approximately the same angle notexceeding 30 from the vertical.- 9 -

When towing, lifting or transporting the compressorin any way, the battery switch must always be in theOFF position!To lift a unit, all loose or pivoting parts, e.g. doors andtowbar, shall first be securely fastened.Do not attach cables, chains or ropes directly to thelifting eye; apply a crane hook or lifting shacklemeeting local safety regulations. Never allow sharpbends in lifting cables, chains or ropes.Helicopter lifting is not allowed.It is strictly forbidden to dwell or stay in the risk zoneunder a lifted load. Never lift the unit over people orresidential areas. Lifting acceleration and retardationshall be kept within safe limits.1 Before towing the unit:

- ascertain that the pressure vessel(s) is (are)depressurized,

- check the towbar, the brake system and thetowing eye. Also check the coupling of thetowing vehicle,

- check the towing and brake capability of thetowing vehicle,

- check that the towbar, jockey wheel or standleg is safely locked in the raised position,

- ascertain that the towing eye can swivel freelyon the hook,

- check that the wheels are secure and that thetyres are in good condition and inflatedcorrectly,

- connect the signalisation cable, check all lightsand connect the pneumatic brake couplers,

- attach the safety break-away cable or safetychain to the towing vehicle,

2 To tow a unit use a towing vehicle of amplecapacity. Refer to the documentation of thetowing vehicle.

3 If the unit is to be backed up by the towingvehicle, disengage the overrun brake mechanism(if it is not an automatic mechanism).

4 Never exceed the maximum towing speed of theunit (mind the local regulations).

5 Place the unit on level ground and apply theparking brake before disconnecting the unit fromthe towing vehicle. Unclip the safety break-awaycable or safety chain. If the unit has no parkingbrake or jockey wheel, immobilize the unit byplacing chocks in front of and/or behind thewheels. When the towbar can be positionedvertically, the locking device must be applied andkept in good order.

6 To lift heavy parts, a hoist of ample capacity,tested and approved according to local safetyregulations, shall be used.

7 Lifting hooks, eyes, shackles, etc., shall never bebent and shall only have stress in line with theirdesign load axis. The capacity of a lifting devicediminishes when the lifting force is applied at anangle to its load axis.

8 For maximum safety and efficiency of the liftingapparatus all lifting members shall be applied asnear to perpendicular as possible. If required, alifting beam shall be applied between hoist andload.

9 Never leave a load hanging on a hoist.10 A hoist has to be installed in such a way that the

object will be lifted perpendicular. If that is notpossible, the necessary precautions must be takento prevent load-swinging, e.g. by using two

11 Locate the unit away from walls. Take allprecautions to ensure that hot air exhausted fromthe engine and driven machine cooling systemscannot be recirculated. If such hot air is taken inby the engine or driven machine cooling fan, thismay cause overheating of the unit; if taken in forcombustion, the engine power will be reduced.

12 Before moving the compressor, switch it off.13 If the warning light on the ABS module or in the

vehicle lights up, please contact Atlas Copco.

SAFETY DURING USE AND OPERATION

1 When the unit has to operate in a fire-hazardousenvironment, each engine exhaust has to beprovided with a spark arrestor to trap incendiarysparks.

2 The exhaust contains carbon monoxide which is alethal gas. When the unit is used in a confinedspace, conduct the engine exhaust to the outsideatmosphere by a pipe of sufficient diameter; dothis in such a way that no extra back pressure iscreated for the engine. If necessary, install anextractor. Observe any existing local regulations.Make sure that the unit has sufficient air intakefor operation. If necessary, install extra air intakeducts.

3 When operating in a dust-laden atmosphere, placethe unit so that dust is not carried towards it by thewind. Operation in clean surroundingsconsiderably extends the intervals for cleaningthe air intake filters and the cores of the coolers.

4 Close the compressor air outlet valve beforeconnecting or disconnecting a hose. Ascertain

11 Before removing the oil filler plug, ensure that thepressure is released by opening an air outlet

- below 85 dB(A): no action needs to be takenfor occasional visitors staying a limited time- 10 -

that a hose is fully depressurized beforedisconnecting it. Before blowing compressed airthrough a hose or air line, ensure that the open endis held securely, so that it cannot whip and causeinjury.

5 The air line end connected to the outlet valvemust be safeguarded with a safety cable, attachednext to the valve.

6 No external force may be exerted on the air outletvalves, e.g. by pulling on hoses or by installingauxiliary equipment directly to a valve, e.g. awater separator, a lubricator, etc. Do not step onthe air outlet valves.

7 Never move a unit when external lines or hosesare connected to the outlet valves, to avoiddamage to valves, manifold and hoses.

8 Do not use compressed air from any type ofcompressor, without taking extra measures, forbreathing purposes as this may result in injury ordeath. For breathing air quality, the compressedair must be adequately purified according to locallegislation and standards. Breathing air mustalways be supplied at stable, suitable pressure.

9 Distribution pipework and air hoses must be ofcorrect diameter and suitable for the workingpressure. Never use frayed, damaged ordeteriorated hoses. Replace hoses and flexiblesbefore the lifetime expires. Use only the correcttype and size of hose end fittings and connections.

10 If the compressor is to be used for sand-blastingor will be connected to a common compressed-airsystem, fit an appropriate non-return valve (checkvalve) between compressor outlet and theconnected sand-blasting or compressed-airsystem. Observe the right mounting position/direction.

system of a hot engine. Wait until the engine hassufficiently cooled down.

13 Never refill fuel while the unit is running, unlessotherwise stated in the Atlas Copco InstructionBook (AIB). Keep fuel away from hot parts suchas air outlet pipes or the engine exhaust. Do notsmoke when fuelling. When fuelling from anautomatic pump, an earthing cable should beconnected to the unit to discharge staticelectricity. Never spill nor leave oil, fuel, coolantor cleansing agent in or around the unit.

14 All doors shall be shut during operation so as notto disturb the cooling air flow inside thebodywork and/or render the silencing lesseffective. A door should be kept open for a shortperiod only e.g. for inspection or adjustment.

15 Periodically carry out maintenance worksaccording to the maintenance schedule.

16 Stationary housing guards are provided on allrotating or reciprocating parts not otherwiseprotected and which may be hazardous topersonnel. Machinery shall never be put intooperation, when such guards have been removed,before the guards are securely reinstalled.

17 Noise, even at reasonable levels, can causeirritation and disturbance which, over a longperiod of time, may cause severe injuries to thenervous system of human beings. When the soundpressure level, at any point where personnelnormally has to attend, is:- below 70 dB(A): no action needs to be taken,- above 70 dB(A): noise-protective devices

should be provided for people continuouslybeing present in the room,

only,- above 85 dB(A): room to be classified as a

noise-hazardous area and an obvious warningshall be placed permanently at each entranceto alert people entering the room, for evenrelatively short times, about the need to wearear protectors,

- above 95 dB(A): the warning(s) at theentrance(s) shall be completed with therecommendation that also occasional visitorsshall wear ear protectors,

- above 105 dB(A): special ear protectors thatare adequate for this noise level and thespectral composition of the noise shall beprovided and a special warning to that effectshall be placed at each entrance.

18 The unit has parts, which may be accidentallytouched by personnel, of which the temperaturecan be in exess of 80 C (176 F). The insulationor safety guard, protecting these parts shall not beremoved before the parts have cooled down toroom temperature.

19 Never operate the unit in surroundings wherethere is a possibility of taking in flammable ortoxic fumes.

20 If the working process produces fumes, dust orvibration hazards, etc., take the necessary steps toeliminate the risk of personnel injury.

21 When using compressed air or inert gas to cleandown equipment, do so with caution and use theappropriate protection, at least safety glasses, forthe operator as well as for any bystander. Do notapply compressed air or inert gas to your skin ordirect an air or gas stream at people. Never use itto clean dirt from your clothes.

22 When washing parts in or with a cleaning solvent,provide the required ventilation and use

appropriate protection such as a breathing filter,safety glasses, rubber apron and gloves, etc.

23 Safety shoes should be compulsory in anyworkshop and if there is a risk, however small, offalling objects, wearing of a safety helmet shouldbe included.

24 If there is a risk of inhaling hazardous gases,fumes or dust, the respiratory organs must beprotected and depending on the nature of thehazard, so must the eyes and skin.

25 Remember that where there is visible dust, thefiner, invisible particles will almost certainly bepresent too; but the fact that no dust can be seenis not a reliable indication that dangerous,invisible dust is not present in the air.

26 Never operate the unit at pressures or speedsbelow or in excess of its limits as indicated in thetechnical specifications.

27 Do not use aerosol types of starting aids such asether. Such use could result in an explosion andpersonal injury.

Maintenance, overhaul and repair work shall only becarried out by adequately trained personnel; ifrequired, under supervision of someone qualified forthe job.1 Use only the correct tools for maintenance and

repair work, and only tools which are in goodcondition.

2 Parts shall only be replaced by genuine AtlasCopco replacement parts.

3 All maintenance work, other than routineattention, shall only be undertaken when the unitis stopped. Steps shall be taken to preventinadvertent starting. In addition, a warning signbearing a legend such as work in progress; donot start shall be attached to the startingequipment. On engine-driven units the batteryshall be disconnected and removed or theterminals covered by insulating caps. Onelectrically driven units the main switch shall belocked in open position and the fuses shall betaken out. A warning sign bearing a legend suchas work in progress; do not supply voltage shallbe attached to the fuse box or main switch.

4 Before dismantling any pressurized component,the compressor or equipment shall be effectivelyisolated from all sources of pressure and the entiresystem shall be relieved of pressure. Do not relyon non-return valves (check valves) to isolatepressure systems. In addition, a warning signbearing a legend such as work in progress; donot open shall be attached to each of the outletvalves.

5 Prior to stripping an engine or other machine orundertaking major overhaul on it, prevent allmovable parts from rolling over or moving.

clothing near the engine air intake.7 Never use flammable solvents for cleaning (fire-

risk).8 Take safety precautions against toxic vapours of

cleaning liquids.9 Never use machine parts as a climbing aid.10 Observe scrupulous cleanliness during

maintenance and repair. Keep away dirt, coverthe parts and exposed openings with a clean cloth,paper or tape.

11 Never weld on or perform any operationinvolving heat near the fuel or oil systems. Fueland oil tanks must be completely purged, e.g. bysteam-cleaning, before carrying out suchoperations. Never weld on, or in any way modify,pressure vessels. Disconnect the alternator cablesduring arc welding on the unit.

12 Support the towbar and the axle(s) securely ifworking underneath the unit or when removing awheel. Do not rely on jacks.

13 Do not remove any of, or tamper with, the sound-damping material. Keep the material free of dirtand liquids such as fuel, oil and cleansing agents.If any sound-damping material is damaged,replace it to prevent the sound pressure level fromincreasing.

14 Use only lubricating oils and greasesrecommended or approved by Atlas Copco or themachine manufacturer. Ascertain that theselected lubricants comply with all applicablesafety regulations, especially with regard toexplosion or fire-risk and the possibility ofdecomposition or generation of hazardous gases.Never mix synthetic with mineral oil.

16 When performing any operation involving heat,flames or sparks on a machine, the surroundingcomponents shall first be screened with non-flammable material.

17 Never use a light source with open flame forinspecting the interior of a machine.

18 Disconnect battery-clamp before startingelectrical servicing or welding (or turn battery-switch in off position).

19 When repair has been completed, the machineshall be barred over at least one revolution forreciprocating machines, several revolutions forrotary ones to ensure that there is no mechanicalinterference within the machine or driver. Checkthe direction of rotation of electric motors whenstarting up the machine initially and after anyalteration to the electrical connection(s) or switchgear, to check that the oil pump and the fanfunction properly.

20 Maintenance and repair work should be recordedin an operators logbook for all machinery.Frequency and nature of repairs can reveal unsafeconditions.

or overhaul, check that operating pressures,temperatures and speeds are correct and that thecontrol and shutdown devices function correctly.

TOOL APPLICATIONS SAFETY

Apply the proper tool for each job. With theknowledge of correct tool use and knowing thelimitations of tools, along with some common sense,many accidents can be prevented.Special service tools are available for specific jobsand should be used when recommended. The use ofthese tools will save time and prevent damage toparts.

SPECIFIC SAFETY PRECAUTIONS Pressure vesselsMaintenance/installation requirements:

Safety valvesOperating & Maintenance- 13 -

BatteriesWhen servicing batteries, always wear protectingclothing and glasses.1 The electrolyte in batteries is a sulphuric acid

solution which is fatal if it hits your eyes, andwhich can cause burns if it contacts your skin.Therefore, be careful when handling batteries,e.g. when checking the charge condition.

2 Install a sign prohibiting fire, open flame andsmoking at the post where batteries are beingcharged.

3 When batteries are being charged, an explosivegas mixture forms in the cells and might escapethrough the vent holes in the plugs. Thus anexplosive atmosphere may form around thebattery if ventilation is poor, and can remain inand around the battery for several hours after ithas been charged. Therefore:- never smoke near batteries being, or having

recently been, charged,- never break live circuits at battery terminals,

because a spark usually occurs.4 When connecting an auxiliary battery (AB) in

parallel to the unit battery (CB) with boostercables: connect the + pole of AB to the + pole ofCB, then connect the - pole of CB to the mass ofthe unit. Disconnect in the reverse order.

1 The vessel can be used as pressure vessel or asseparator and is designed to hold compressed airfor the following application:- pressure vessel for compressor,- medium AIR/OIL,and operates as detailed on the data plate of thevessel:- the maximum working pressure ps in bar (psi),- the maximum working temperature Tmax in

C (F),- the minimum working temperature Tmin in C

(F),- the capacity of the vessel V in l (US gal).

2 The pressure vessel is only to be used for theapplications as specified above and in accordancewith the technical specifications. Safety reasonsprohibit any other applications.

3 National legislation requirements with respect tore-inspection must be complied with.

4 No welding or heat treatment of any kind ispermitted to those vessel walls which are exposedto pressure.

5 The vessel is provided and may only be used withthe required safety equipment such asmanometer, overpressure control devices, safetyvalve, etc.

6 Draining of condensate shall be performed dailywhen vessel is in use.

7. Installation, design and connections should not be changed.

8. Bolts of cover and flanges may not be used for extra fixation.

Only trained and technically competent personnelshould consider overhaul, re-set or performancetesting of safety valves.The safety valve is supplied with either a lead securityseal or crimped cover to deter unauthorised access tothe pressure regulation device.Under no circumstances should the set pressure of thesafety valve be altered to a different pressure than thatstamped on the valve without the permission of theinstallation designer.If the set pressure must be altered then use onlycorrect parts supplied by Atlas Copco and inaccordance with the instructions available for thevalve type.Safety valves must be frequently tested and regularlymaintained.The set pressure should be periodically checked foraccuracy.When fitted, the compressors should be operated atpressures not less than 75% of the set pressure toensure free and easy movement of internal parts.The frequency of tests is influenced by factors such asthe severity of the operating environment andaggressiveness of the pressurised medium.Soft seals and springs should be replaced as part of themaintenance procedure.Do not paint or coat the installed safety valve (see alsoPreventive maintenance schedule).

GENERAL DESCRIPTION

The XAMS 287 Dd - XAMS 600 DD7 is a silenced,single-stage, oil-injected screw compressor, built fora nominal effective working pressure of 8.6 bar(125 psi).The XAHS 237 Dd - XAHS 500 DD7 is a silenced,single-stage, oil-injected screw compressor, built fora nominal effective working pressure of 12 bar(175 psi).

EngineThe compressors XAMS 287 Dd - XAMS 600 DD7and XAHS 237 Dd - XAHS 500 DD7 are driven by 6cylinder in-line liquid-cooled diesel engines.The engines power is transmitted to the compressorelement through a heavy-duty coupling.

CompressorThe compressor casing houses two screw-type rotors,mounted on ball and roller bearings. The male rotor,driven by the engine, drives the female rotor. Thecompressor delivers pulsation-free air.Injected oil is used for sealing, cooling andlubricating purposes.

Compressor oil systemThe oil is boosted by air pressure. The system has nooil pump.The oil is removed from the air, in the air/oil vessel atfirst by centrifugal force, secondly through the oilseparator element.The vessel is provided with an oil level indicator.

RegulationThe compressor is provided with a continuousregulating system and a blow-off valve which isintegrated in the unloader assembly. The valve isclosed during operation by air receiver pressure andopens by air receiver pressure via the compressorelement when the compressor is stopped.When the air consumption increases, the air receiverpressure will decrease and vice versa.This receiver pressure variation is sensed by theregulating valve which, by means of control air to theunloader and an electronic engine speed regulator,matches the air output to the air consumption. The airreceiver pressure is maintained between the pre-selected working pressure and the correspondingunloading pressure.

AIR FLOW

Air drawn through the airfilter (AFce) into thecompressor element (CE) is compressed. At theelement outlet, compressed air and oil pass into the airreceiver/oil separator (AR/OS).The check valve (CV) prevents blow-back ofcompressed air when the compressor is stopped. Inthe air receiver/oil separator (AR/OS), most of the oilis removed from the air/oil mixture.The oil collects in the receiver and on the bottom ofthe separator element.The air leaves the receiver via a minimum pressurevalve (MPV) which prevents the receiver pressurefrom dropping below the minimum working pressure,even when the air outlet valves are open (specified insection Limitations). This ensures adequate oilinjection and prevents oil consumption. Theminimum pressure valve (MPV) also functions as acheck valve.The system comprises temperature sensors (TS),regulating pressure sensors (RPS) and a workingpressure sensor (WPS).

OIL SYSTEM

The lower part of the air receiver (AR) serves as oiltank.Air pressure forces the oil from the air receiver/oilseparator (AR/OS) through the oil cooler (OC), the oilfilters (OFc) and the oil stop valve (OSV) to thecompressor element (CE).When the compressor is stopped and / or there is nopressure in the system, the oil stop valve (OSV)prevents the oil from flowing back into thecompressor element.The thermostatic by-pass valve (TBV) starts openingwhen the oil temperature is 70 C (158 F).The compressor element has an oil gallery in thebottom of its casing. The oil for rotor lubrication,cooling and sealing is injected through holes in thegallery.Lubrication of the bearings is ensured by oil injectedinto the bearing housings.The injected oil, mixed with the compressed air,leaves the compressor element and re-enters the airreceiver, where it is separated from the air asdescribed in section Air flow. The oil that collects inthe bottom of the oil separator element is returned tothe system through a scavenging line (SL), which isprovided with a flow restrictor.The oil filter by-pass valve opens when the pressuredrop over the filter is above normal because of aclogged filter. The oil then by-passes the filterwithout being filtered. For this reason, the oil filtermust be replaced at regular intervals (see sectionPreventive maintenance schedule).

CONTINUOUS PNEUMATIC REGULATING SYSTEM

(CE)(UA)

(BOV)

(AR)(RV)

- 23 -

The compressor is provided with a continuouspneumatic regulating system and a blow-off valve(BOV) which is integrated in the unloader assembly(UA). The valve is closed during operation by outletpressure of the compressor element and opens by airreceiver pressure when the compressor is stopped.When the air consumption increases, the air receiverpressure will decrease and vice versa. This receiverpressure variation is sensed by the regulating valve(RV) which, by means of control air to the unloaderassembly (UA), matches the air output to the airconsumption. The air receiver pressure is maintainedbetween the pre-selected working pressure and thecorresponding unloading pressure.When starting the compressor, the throttle valve iskept closed via receiver pressure. The compressorelement (CE) takes in air and pressure builds up in thereceiver (AR). The throttle valve is closed. The airoutput is controlled from maximum output (100%) tono output (0%) by:1. Speed control of the engine between maximum

load speed and unloading speed (the output of a screw compressor is proportional to the rotating speed).

2. Air inlet throttling.If the air consumption is equal to or exceeds themaximum air output, the engine speed is held atmaximum load speed and the throttle valve is fullyopen.

If the air consumption is less than the maximum airoutput, air receiver pressure increases and theregulating valve supplies control air to throttle valveto reduce the air output and holds air receiver pressurebetween the normal working pressure and thecorresponding unloading pressure. Unloadingpressure = normal working pressure + 1.5 to 2 bar (22to 29 psi).When the air consumption is resumed, the blow offvalve (BOV) closes and the throttle valve graduallyopens the air intake and the electronic speed regulatorincreases the engine speed.The construction of the regulating valve (RV) is suchthat any increase (decrease) of the air receiverpressure above the pre-set valve opening pressureresults in a proportional increase (decrease) of thecontrol pressure to the throttle valve and theelectronic speed regulator.Part of the control air is vented to atmosphere, andany condensate discharged, through the vent holes.

STARTING / STOPPING- 31 -

BEFORE STARTING

1. Before initial start-up, prepare battery for operation if not already done. See section Recharging a battery.

2. With the compressor standing level, check the level of the engine oil. Add oil, if necessary, to the upper mark on dipstick. Also check the engine coolant level. Consult the Engine Operation Manual for the type of coolant and type and viscosity grade of the engine oil.

3. Check the level of the compressor oil. The pointer of oil level gauge (OLG) should register in the green range. Add oil if necessary. See section Engine oil for the oil to be used.

4. Check that the fuel tank contains sufficient fuel. Top up, if necessary. Consult the Engine Operation Manual for the type of fuel.

5. Drain any water and sediment from the fuel filters until clean fuel flows from the drain cock. See section Priming instructions.

6. Empty the dust trap of each air filter (AF). See section Cleaning the dust trap.

7. Clogged air filter(s) will be indicated on the display of the control panel, see section Fault codes. If indicated, replace the filter elements.

8. Check coolant level in engine coolant top tank. Top up, if necessary. Consult the Engine Operation Manual for coolant specifications.

9. Attach the air line(s) to the closed air outlet valve(s). Connect the safety chain.

Safety precautions

Make sure the fuel tank is filled up.

Before removing oil filler plug (FP),ensure that the pressure is released byopening an air outlet valve.

No external force may be applied to theair outlet valve(s), e.g. by pulling hosesor by connecting equipment directly tothe valve(s).

Do not disconnect power supply tocontrol box in any way when the controlbox is switched on. This will causememory loss.

When the compressor is put in operationfor the first time and after running out offuel or changing the fuel filter, follow thespecific start procedure as described insection Priming instructions.

Do not switch off the circuit breakerwhen the control box is switched on. Thiswill cause memory loss.

OIL AND OIL FILTER CHANGE- 51 -

ENGINE OIL AND OIL FILTER CHANGE

See section Preventive maintenance schedule.

COMPRESSOR OIL AND OIL FILTER CHANGE

The quality and the temperature of the oil determinethe oil change interval.The prescribed interval is based on normal operatingconditions and an oil temperature of up to 100 C(212 F) (see section Preventive maintenanceschedule).When operating in high ambient temperatures, in verydusty or high humidity conditions, it is recommendedto change the oil more frequently.

1. Run the compressor until warm. Close the outlet valve(s) (1) and stop the compressor. Wait until the pressure is released through the automatic blow-down valve. Unscrew the oil filler plug (2) one turn. This uncovers a vent hole, which permits any pressure in the system to escape.

2. Drain the compressor oil by removing all relevant drain plugs. Drain plugs are located at the air receiver (AR) and compressor oil cooler (OC). Catch the oil in a drain pan. Screw out the filler plug (2) to speed up draining. After draining, place and tighten the drain plugs.

3. Remove the oil filters (3), e.g. by means of a special tool. Catch the oil in a drain pan.

4. Clean the filter seat on the manifold, taking care that no dirt drops into the system. Oil the gasket of the new filter element. Screw it into place until the gasket contacts its seat, then tighten one half turn only.

5. Fill the air receiver until the pointer of the oil level gauge is in the upper part of the green area. Be sure that no dirt gets into the system. Reinstall and tighten the filler plug (2).

6. Start the compressor and let it run unloaded for a few minutes.

7. Stop the compressor, wait a few minutes and top up with oil until the pointer of the oil level gauge is in the upper part of the green area.

In this case, contact Atlas Copco.

Never add more oil. Overfilling results inoil consumption.

TOPPING UP THE COMPRESSOR OIL- 52 -

1. Stop the compressor and be sure that all pressure has been released by opening the filler plug (2) one turn.

2. Wait a few minutes until the oil level is constant (oil level gauge (1)).

3. Remove the oil filler plug (2) and top up with oil until the pointer of the oil level gauge (1) is in the upper part of the green area.

4. Reinstall and tighten the filler plug (2).

COMPRESSOR OIL FLUSHING PROCEDURE- 53 -

To avoid problems when changing over to a new typeof oil (see table) a special Compressor Oil FlushingProcedure has to be followed. The table is only validin case the replaced oil has not exceeded its lifetime.For more information consult Atlas Copco Servicedept.Aged oil can be recognized best by using an oilsampling analysis program. Indicators for aged oil arestrong smell, or contamination like sludge andvarnish inside the oil vessel and oil stop valve or abrownish colour of the oil.Whenever aged oil is discovered, eg. when changingthe oil separator, contact Atlas Copco Service dept. tohave your compressor cleaned and flushed.1. First thoroughly drain the system when the oil is

warm, leaving as little oil in the system as feasible especially in dead areas, if possible blow out remaining oil by pressurising the oil system. Check the instruction manual for detailed description.

2. Remove the compressor oil filter(s).3. Open the oil vessel and remove the oil separator

element.

4. Check the interior of the oil vessel (see pictures). If varnish deposits are discovered, contact Atlas Copco Service dept. and do not continue.

5. Put in a new oil separator, screw on new compressor oil filter(s) and close the oil vessel according to the instructions.

6. Fill the oil vessel with the minimum amount of replacement oil, run the compressor under light load conditions for 30 minutes.

7. Thoroughly drain the system when the oil is warm, leaving as little oil in the system as feasible, especially in dead areas, if possible blow out remaining oil by pressurising the oil.

8. Fill the system with the final oil charge.9. Run the compressor under light load conditions

for 15 minutes and check for leakage. 10. Check the oil level and top up if necessary.11. Collect all waste lubricant used during the

flushing process and dispose of it in accordance with the applicable procedures for managing waste lubricant.
