1. PRECAUTIONS
These compressors are not suitable for outdoor use.
THINGS TO DO
• The compressor must be used in a suitable environment (well ventilated
with an ambient temperature of between +5°C and +40°C) and never in
places affected by dust, acids, vapors, explosive or ammable gases.
• Always maintain a safety distance of at least 4 meters between the compressor
and the work area.
• Any coloring of the belt guards of the compressor during painting operations
indicates that the distance is too short.
• Inserttheplugoftheelectriccableinasocketofsuitableshape,voltageand
frequencycomplyingwithcurrentregulations.
• For3-phaseversions,havetheplugttedbyaqualiedelectricianaccording
tolocalregulations.Whenstartingthecompressorforthersttime,checkthe
correct direction of rotation and that this matches the direction indicated by
thearrowonthebeltguard(versionswithplasticprotection)oronthemotor
(versionswithmetalprotection).
• Use extension cables with a maximum length of 5 meters and of suitable
cross-section.
• The use of extension cables of different length and also of adapters and multiple
sockets should be avoided.
• Always use the switch of the pressure switch to switch off the compressor
orusetheswitchoftheelectricpanelformodelsequippedwiththis.Never
switch off the compressor by pulling out the plug in order to avoid restart with
pressure in the head.
• Always use the handle to move the compressor.
• Whenoperating,thecompressormustbeplacedonastable,horizontalsurface
to guarantee correct lubrication.
• Position the compressor at least 50 cm from the wall to permit optimal circulation
of fresh air and to guarantee correct cooling.
THINGS NOT TO DO
• Neverdirectthejetofairtowardspersons,animalsoryourbody.(Alwayswear
safetygogglestoprotectyoureyesfromyingobjectsthatmaybeliftedbythejet).
• Neverdirectthejetofliquidssprayedbytoolsconnectedtothecompressor
towards the compressor.
• Never use the appliance in your bare feet or with wet hands or feet.
• Never pull the power cable to pull the plug out of the socket or to move the
compressor.
• Never leave the appliance exposed to adverse weather conditions (rain,
sun,fog,snow).
• Never transport the compressor with the reservoir pressurized.
• Neverweldormachinethereservoir.Inthecaseoffaultsorcorrosion,replace
it completely.
• Never allow inexpert persons to use the compressor. Keep children and animals
away from the work area.
• Thisapplianceisnotintendedforusebypersons(includingchildren)withreduced
physical,sensoryormentalcapabilities,orlackofexperienceandknowledge,
unless they have been given supervision or instruction concerning the use of
the appliance by a person responsible for their safety.
• Children should be supervised to ensure that they do not play with the appliance.

• Children should be supervised to ensure that they do not play with the appliance.
• Neverposition ammable or nylonorfabric articles close toand/oronthe
compressor.
• Nevercleanthecompressorwithammableliquidsorsolvents.Cleanwitha
dampclothonly,aftermakingsurethatyouhaveunpluggedthecompressor.
• The compressor is designed only to compress air and must not be used for
any other type of gas.
• The compressed air produced by the compressor cannot not be used for
pharmaceutical,foodorhospitalpurposesexceptafterparticulartreatments.
Itisnotsuitableforllingtheairbottlesofscubadivers.
• Never use the compressor without guards (belt guard) and never touch
moving parts.
THINGS YOU SHOULD KNOW
• To avoid overheating of the electric motor, this compressor is designed
for intermittent operation as indicated on the dataplate(forexample,S3-
50means5minutesONand5minutesOFF).Inthecaseofoverheating,the
thermalcutoutofthemotortrips,automaticallycuttingoffthepowerwhenthe
temperatureistoohighduetoexcesscurrenttake-off.
• To facilitate machine restart, it is important not only to carry out the
operations indicated but also to set the button of the pressure switch,
returning this to the OFF position and then ON again (gures 1a-1b).
• Onsingle-phaseversions,presstheresetbuttonontheterminalboxofthe
motor(g. 2).
• On3-phaseversions,operatemanuallyonthebuttonofthepressureswitch,
returningthistotheONposition,orpressthebuttonofthethermalcutoutinside
theboxoftheelectricpanel(gures 3a-3b-3c).
• Thesingle-phaseversionsarettedwithapressureswitchequippedwitha
delayedclosingairventvalve(orwithavalvelocatedonthecheckvalve)that
facilitatesmotorstart-up;thereforeafew-secondjetofairfromthis,withthe
reservoirempty,istobeconsiderednormal.
• To guarantee machine safety, all the compressors are tted with a safety
valvethatisactivatedinthecaseoffailureofthepressureswitch(g. 4a-4b).
• Alltwo-stagecompressorsareequippedwithsafetyvalvesontheairdelivery
manifold to the reservoir and on the connection hose between the low
and high pressure located on the head. These are activated in the case of
malfunctioning(g. 5).
 Thesafetyvalveissettoavoidover-pressurizationoftheairtanks.Thisvalveis
factorypre-setandwillnotfunctionunlesstankpressurereachesthispressure.
Do not attempt to adjust or eliminate this safety device.
 Anyadjustmentstothisvalvecouldcauseseriousinjury.Ifthisdevicerequires
serviceormaintenance,seeanAuthorizedServiceCenter.
• The red notch on the pressure gauge refers to the maximum operating pressure
of the tank. It does not refer to the adjusted pressure.
• Whenconnectinganair-poweredtooltoahoseofcompressedairsupplied
bythecompressor,interruptionoftheowofairfromthehoseiscompulsory.
• Useofthecompressedairforthevariouspurposesenvisaged(ination,air-
poweredtools,painting,washingwithwater-baseddetergentsonly,etc.)requires
knowledge of and compliance with the rules established for each individual use.
• Please check that the air consumption and the maximum working pressure of
thepneumatictoolandconnectionpipes(withthecompressor)tobeused,
are compatible with the pressure set on the pressure regulator and with the
amount of air supplied by the compressor.
• Supply hoses atpressures above7 bar shouldbe equippedwith a safety
cable(e.g.awirerope).
2. START-UP AND USE
• Fitthesuppliedwheelsasshowningures19 and 20.Forversionswithxed
feet,assemblethevibration-dampersiffurnished(g. 21).
• Check for correspondence between the compressor plate data with the actual
specicationsoftheelectricalsystem.Avariationof±10%withrespectofthe
rated value is allowed.
• Insert the power plug in a suitable socket checking that the button of the
pressure switch located on the compressor is in the “O” (OFF) position
(gures 6a-6b-6c-6d).
• Forthe3-phaseversions,connecttheplugtoapanelprotectedbysuitablefuses.
