2.3 START-UP
Check that the mains power matches that indicated
on the electrical rating plate (fig.5), the permissible tole-
rance range is ± 5%.
Insert the plug in the power socket and start the com-
pressor by bringing the switch to position "I / On" (fig.6).
Version without tank
When the maximum pressure is reached, the com-
pressor automatically vents excess air through the rele-
vant valve. The compressor does not stop automatical-
ly. Press the ON/OFF button to turn off the compressor
Version with tank
The compressor is fully automatic, and is controlled
by the pressure switch which stops it when tank pressu-
re reaches maximum value and restarts it when it falls
to minimum value. The pressure difference between
maximum and minimum values is usually about 2 bar
(29 psi).
E.g.: the compressor stops when it reaches 8 bar
(116 psi) and restarts automatically when the pressure
inside the tank drops to 6 bar (87 psi).
After connecting the compressor to the power line,
load it to maximum pressure and check corrrect fun-
ctioning.
NOTE: some models could be equipped with a di-
scharge valve on the top of the head, useful to facilitate
the next start. In this case it is normal a puff of air when
compressor stops
These models have a front door (10) (Fig. 9 and 10)
containing a spiral hose compartment.
Using the air outlet hose: in the version without tank,
the hose is connected directly to the compressor, while
in the version with tank the spiral hose (11) must be
extracted and connected to the relevant quick coupling
(3 - Fig. 10).
2.4 MOTOR PROTECTION DEVICES
Compressors are equipped with an automatic ther-
mal breaker located inside the winding, this stops the
compressor when motor temperature reaches exces-
sively high values.
If the breaker is tripped, the compressors restarts au-
tomatically after 10 to 15 minutes
If the protection device trips again, it's higly recco-
mended to stop the compressor, disconnect electric
plug and contact the nearest service centre.
Note for three phases model: compressors must be
connected to a power socket protected by a suitable
differential switch (magneto-thermal, see. table C-pa-
ge.8).
2.5 ADJUSTING THE WORKING PRESSURE
You do not have to use the maximum operating pres-
sure at all times. On the contrary, the pneumatic tool
being used often requires less pressure. Check correct
pressure on tool's manual.
Version without tank.
In this compressors, the operating pressure cannot
be adjusted, the generated air is used directly (see 2.3).
Version with tank.
To adjust the pressure, operate on the knob of the
reducer (4) (fig. 8) and adjust the pressure to the de-
sired value by turning the knob clockwise to increase
it or counterclockwise to decrease it until the desired
pressure is reached (as it can be checked on pressure
gauge (5 - fig. 8).
For those models without pressure reducer, a sui-
table pressure reducer must be fitted on the distribution
line by the user.
2.6 CAUTIONS WHILE USING
Do not unscrew any connection while the tank is
pressurised, always check if the tank is pressure free.
Do not drill holes, weld or purposely deform the air
tank.
Do not do any jobs on the compressor unless you
have disconnected the power plug.
Temperature in operating ambient: 0°C +35°C.
Do not aim jets of water or inflammable liquids on
the compressor.
Do not place inflammable objects near the compres-
sor.
Never aim the air jet at people or animals
Do not transport the compressor while the tank is
pressurised
Be careful with regard to some parts of the com-
pressor such as the head and delivery tubes, as they
can reach high temperatures. Do not touch these parts
(fig.11)
Transport the compressor, lifting or pulling it with the
appropriate grips or handles.
Keep children and animals well away from the ma-
chine operating area.
If using the compressor for painting:
a) Do not work in closed environments or near to na-
ked flames
b) Make sure there is adequate exchange of air
c) Protect your nose and mouth with a mask.
If the electrical cable or plug are damaged, do not
use the compressor and contact an authorised service
centre to replace the faulty element.
Do not insert hands and/or any object inside pro-
tection grilles.
