1.  PRECAUTIONS
An  ACOUSTIC  PRESSURE  value  of  4  m. 
corresponds  to  the  ACOUSTIC  POWER 
value stated on the yellow label located on 
the compressor, minus 20 dB.
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 flammable 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 
distanceistooshort.
●  Insert the plug of the electric cable in a socket of 
suitable shape, voltage and frequency complying 
withcurrentregulations.
●  Useextensioncableswithamaximumlengthof5
metersandofsuitablecross-section.
●  The use of extension cables of different length
and also of adapters and multiple sockets should 
beavoided.
●  Always  use  the  switch  I/O  to  switch  off  the 
compressor.
●  Alwaysusethehandletomovethecompressor.
●  When operating, the compressor must be placed 
onastable,horizontalsurface.
THINGS NOT TO DO
●  Never direct the jet of air towards persons, animals 
or your body. (Always wear safety goggles to
protect your eyes against flying objects that may 
beliftedbythejetofair).
●  Never  direct  the  jet  of  liquids  sprayed  by  tools 
connected  to  the  compressor  towards  the 
compressor.
●  Never  use  the  appliance  with  bare  feet  or  wet 
handsorfeet.
●  Never pull the power cable to disconnect the plug 
fromthesocketortomovethecompressor.
●  Never  leave  the  appliance  exposed  to  adverse 
weatherconditions.
●  Never transport the compressor with the receiver 
underpressure.
●  Donotweldormachinethereceiver.Inthecase

●  Never  allow  inexpert  persons  to  use  the 
compressor. Keep children and animals at a
distancefromtheworkarea.
●  Do not position flammable or nylon/fabric objects 
closedtoand/oronthecompressor.
●  Never clean the compressor with flammable liquids 
orsolvents.Checkthatyouhaveunpluggedthe

●  The compressor must be used only for air
compression.Donotusethecompressorforany

●  Thecompressedairproducedbythecompressor
cannot  not  be  used  for  pharmaceutical,  food 
or  medical  purposes  except  after  particular 
treatments  and  cannot  be  used  to  fill  the  air 
bottlesofscubadivers.
THINGS YOU SHOULD KNOW
●  To  avoid  overheating  of  the  electric  motor, 
this  compressor  is  designed  for  intermittent 
operation  as  indicated  on  the  technical 
dataplate(forexample,S3-25means2.5minutes
ON,7.5minutesOFF).Inthecaseofoverheating,
the thermal cutout of the motor trips, automatically 
cutting  off  the  power  when  the  temperature  is 
toohigh.Themotorrestartsautomaticallywhen
normaltemperatureconditionsarerestored.
●  To  facilitate  restart  of  the  compressor,  in 
addition  to  the  operations  indicated,  it  is 
important to return the button of the pressure 
switch  to  the  OFF  position  and  then  to  ON 
again (paragraph 5.4).
●  Thecompressorsarefittedwithapressureswitch
equipped  with  a  delayed  closing  air  discharge 
valve which facilitates start-up of the motor (D 
200/8/6only).Thereforeventingofair from this
valve for a few seconds with the receiver empty is 
normal.
●  All the compressors are fitted with a safety valve 
that  is  tripped  in  the  case  of  malfunctioning  of 
the  pressure  switch  in  order  to  assure  machine
