5.2.1 Fitting the tap ball valve (fig. 9)
B
If provided, fit the tap ball valve as shown in figure 9.
5.3 Fitting the transport handle (fig. 10)
If provided, screw the transport handle (ref. 9) to the com-
pressor as shown in figure 10.
5.4 Voltage
● Connect the mains cable to a panel protected by suit-
able fuses.
● For the versions fitted with electric panel ("Tandem" con-
trol units or delta/star starters) have installation and con-
nections (to the motor, to the pressure switch and to the
electrovalve if any) carried out by qualified personnel.
● Before you put the equipment into operation, check
whether the motor rotates in the correct direction (see
the direction arrow on the V-belt cover) by switching on
the compressor briefly. If the compressor motor rotates
in the wrong direction, you must correct the rotating
field by reversing the phase converter in the plug (use a
screwdriver to depress the phase converter slightly and
turn it through 180°).
● The motor is equipped with an overload switch. If the
compressor overloads, the overload switch will switch
off the equipment automatically to protect the compres-
sor from overheating. If the overload switch triggers,
wait for the compressor to cool down.
● Long supply cables, extensions, cable reels etc. cause a
drop in voltage and can impede motor start-up.
● In the case of low temperatures below +5°C, motor start-
up is jeopardized as a result of stiffness.
5.5 Starting
● Operating on the switch of the pressure switch (or the
selector for versions with electric panel, (figures 2a-2b-
2c), the compressor starts, pumping air in the reservoir
through the delivery hose. Air is sucked into the so-
called low pressure cylinder liner and precompressed.
It is then routed, through the recirculation hose, into the
so-called high pressure liner and then into the reservoir.
With this work cycle, it is possible to reach higher pres-
sure, with availability of air at 11 bar (15 bar for special
machines).
● On reaching maximum operating pressure (factory-set
during testing), the compressor stops, venting the ex-
cess air present in the head and in the delivery hose
through a valve located under the pressure switch (in
delta/star versions, through an electrovalve that is acti-
vated when the motor stops).
● The absence of pressure in the head facilitates sub-
sequent restart. When air is used, the compressor re-
starts automatically when the lower calibration value
is reached (approx. 2 bar between upper and lower).
The pressure inside the reservoir can be checked on the
gauge provided (ref. 12).
● The compressor continues to operate automatically
with this work cycle until the position of the switch of the
pressure switch (or of the selector of the electric panel,
figures 2a-2b-2c) is modified. To use the compres-
sor again, wait at least 10 seconds after this has been
switched off before restarting.
● In the versions with electric panel, the pressure switch
must always be aligned with the I (ON) position.
● In tandem versions, the control unit provided permits
use of only one of the two compressor groups (if neces-
sary alternatively) or of both at the same time accord-
ing to requirements. In this second case, start-up will be
differentiated slightly to avoid excessively high current
take-off at start-up (timed starting).
● Only the wheel-mounted compressors are fitted with a
pressure reducer (in the versions with fixed feet, it is
usually installed on the use line). Air pressure can be
regulated in order to optimize use of air-powered tools
operating on the knob with the valve open (pulling it up
and turning it in a clockwise direction to increase pres-
sure and counterclockwise to reduce this) (fig. 11).
Once you have set the value required, push the knob
down to lock it.
● The value set can be checked on the gauge (for ver-
sions equipped with this, fig. 11).
● Please check that the air consumption and the
maximum working pressure of the pneumatic
tool to be used are compatible with the pres-
sure set on the pressure regulator and with the
amount of air supplied by the compressor.
● When you have finished working, stop the machine, pull
out the plug and empty the tank.
6. CLEANING AND MAINTENANCE
The service life of the machine depends on maintenance
quality.
Warning!
Pull the power plug before doing any cleaning and
maintenance work on the appliance.
Warning!
Wait until the compressor has completely cooled
down. Risk of burns!
Warning!
Always depressurize the tank before carrying out
any cleaning and maintenance work.
6.1 Cleaning
● Keep the safety devices free of dirt and dust as far as
possible. Wipe the equipment with a clean cloth or blow
