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 maintaina safety distance of atleast 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.
● Forthree-phaseversionshavetheplugfittedbya
qualifiedelectricianaccordingtolocalregulations.
Thefirsttimeyoustartthecompressor,checkthat
the direction of rotation is correct and matches
thatindicatedbythearrowontheconveyor(Fig.
10, the air must be conveyed towards the head of
thecompressor).
● Useextensioncableswithamaximumlengthof5
metersandofsuitablecross-section.
● The use of extension cables of different length
and also of adapters and multiple sockets should
beavoided.
● Always use the switch of the pressure switch to
switchoffthecompressor.
● Alwaysusethehandletomovethecompressor.
● When operating, the compressor must be placed
on a stable, horizontal surface to guarantee
correctlubrication.
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.

● 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

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

● 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(fig. 11-12).
● On certain «V» type versions, the reset button on
