warranty of electrical parts.
To avoid connection errors, we suggest you to
contact a specialised technician.
2.3 START-UP
Check that the mains power matches that indicated
on the electrical data-plate (fig.8), the permissible tole-
rance range is +/-5%.
When first starting compressors operating on 3-pha-
se voltage, check the rotation direction of the cooling
fan by comparing it with the direction of the arrow on the
belt guard or on the protective housing.
Fit the plug in the power socket and start the com-
pressor, turning the pressure switch knob into position
"I/On" (fig.9).
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
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.
On compressors supplied with a pressure reducer,
operating pressure must be correctly adjusted (see
fig.10).
Release the pressure reducer knob by pulling it up,
adjust pressure to the required value by turning the
knob clockwise to increase pressure and anti-clockwi-
se to reduce it.
When you have obtained optimum pressure,
lock the knob by pressing it downward.
For pressure reducers equipped without a pressure
gauge, the set pressure can be seen on the graduated
scale located on the reducer body.
On pressure reducers equipped with a pressre gau-
ge, pressure can be seen on the gauge itself.
WARNING: Some pressure regulators do not have
"push to lock", therefore simply turn the knob to adjust
the pressure.
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.
3. MAINTENANCE
Before attempting any maintenance jobs on the
compressor, make sure of the following:
Master power switch in position "0/Off".
Compressor power switch in position "0/Off"
No pressure in the air tank
Wait for all parts to cool down, so to avoid any burn.
If necessary, remove shroud in order to access inner
parts. Take care to not break or pull any cable or pneu-
matic connections.
