1. PRECAUTIONS
B
An ACOUSTIC PRESSURE value of 4 m. corresponds to the ACOUSTIC
POWER value stated on the 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 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 three-phase versions have the plug fitted by a qualified electrician
according to local regulations. The first time you start the compressor,
check that the direction of rotation is correct and matches that indicated by
the arrow on the conveyor (Fig. 1, the air must be conveyed towards the
head of the compressor).
● 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.
● Always use the handle to move the compressor.
● When operating, the compressor must be placed on a stable, horizontal
surface to guarantee correct lubrication (lubricated versions).
NOT
THINGS 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
be lifted by the jet of air).
● 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 hands or feet.
● Never pull the power cable to disconnect the plug from the socket or to
move the compressor.
● Never leave the appliance exposed to adverse weather conditions.
● Never transport the compressor with the receiver under pressure.
● Do not weld or machine the receiver. In the case of faults or rusting, replace
the entire receiver.
● Never allow inexpert persons to use the compressor. Keep children and
animals at a distance 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.
2. ASSEMBLY
Warning!
You must fully assemble the appliance before using it for the first time.
2.1 Fitting the wheel kit
If provided, the wheel kit must be installed as shown in figure 15.

2.2 Fitting the supporting feet
If provided, the rubber feet must be fitted as shown in figure 16.
2.3 Fitting the transport handle (for models envisaging this)
Screw the transport handle to the compressor as shown in figure 17.
2.4 Fitting the air filter (for models envisaging this)
Remove the transportation stop with a screwdriver or similar and screw the
air filter securely to the equipment (Fig. 18).
2.5 Replacing the oil sealing plug (for models envisaging this)
Remove the transportation cover from the oil filler opening with a screwdriver
Preserve this handbook for future reference

● Children should be supervised to ensure that they do not play with the
appliance.
● Do not position flammable or nylon/fabric objects closed to and/or on the
compressor.
● Never clean the compressor with flammable liquids or solvents. Check that
you have unplugged the compressor and clean with a damp cloth only.
● The compressor must be used only for air compression. Do not use the
compressor for any other type of gas.
● The compressed air produced by the compressor cannot not be used for
pharmaceutical, food or medical purposes except after particular treatments
and cannot be used to fill the air bottles of scuba divers.
THINGS YOU SHOULD KNOW
● To avoid overheating of the electric motor, this compressor is designed
for intermittent operation as indicated on the technical dataplate (for
example, S3-25 means 2.5 minutes ON, 7.5 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. The motor restarts automatically
when normal temperature conditions are restored.
● 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. 2-3-4).
● On certain «V» type versions, the reset button on the terminal box of the
motor must be pressed (fig. 5).
● On three-phase versions, simply return the button of the pressure switch
to the ON position. (fig. 3).
● Single-phase versions are fitted with a pressure switch equipped with a
delayed closing air discharge valve which facilitates start-up of the motor.
Therefore venting of air 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 safety.
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 fitting a tool, the flow of air in output must be switched off.
● When using compressed air, you must know and comply with the safety
precautions to be adopted for each type of application (inflation, pneumatic
tools, painting, washing with water-based detergents only, etc.).
● 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).
and insert the supplied oil dipstick into the oil filler opening (Fig. 19).

3. START-UP AND USE

● Check for correspondence between the compressor plate data with the
actual specifications of the electrical system. A variation of ± 10% with
respect of the rated value is allowed.
● The compressor is equipped with a mains cable with earth wire. Insert the
plug of the electric cable in a socket of suitable shape, voltage and frequency
complying with current regulations (fig. 6), checking that the button of the
pressure switch located on the compressor is in the OFF «O» position.
● For lubricated models, check the oil level using the rod included in the oil
fuel plug (figures 7a-7b) or the sight glass (fig. 7c), and if necessary top up.
● At this point, the compressor is ready for use.
● Operating on the switch of the pressure switch (fig. 3), the compressor
starts, pumping air into the receiver through the delivery pipe.
● When the upper calibration value (set by the manufacturer) has been
reached, the compressor stops, venting the excess air present in the head
and in the delivery pipe through a valve located under the pressure switch.
This facilitates subsequent restart due to the absence of pressure in the
head. When air is used, the compressor restarts automatically when the
lower calibration value is reached (2 bar between upper and lower).
● The pressure in the receiver can be checked on the gauge provided (fig. 8).
● The compressor continues to operate according to this automatic cycle until
the switch of the pressure switch is turned.
● Always wait at least 10 seconds from when the compressor has been
switched off before restarting this.
