ELECTRICAL CONNECTION

The compressor should be grounded while in
use to protect the operator from electric shock. The
compressor is equipped with a three-core cable and
three-pin grounding type plug to fit the proper groun-
ding type socket. Never disassemble the compressor
or carry out other connections to the pressure switch.
WARNING – the grounding must be carried out ac-
cording to EN 60204 norms.
USE OF EXTENSION CABLE
Use only three-way extension cables that have
three-pin connecting plugs and three-pole sockets
that accept the compressor plug.
Do not use extension cables that are damaged or
squashed. An under-rated cable will cause a drop in
line voltage resulting in loss of power and overhea-
ting.
The table shows the correct size to use depending
on the length according to the following parameters :
cable cross.section for maximum length of 20 mt.
220/230V
1,5 mm²
WARNING
Avoid electrical shock hazard. Never use this com-
pressor with a damaged or frayed electrical cord or
extension cord. Inspect all electrical cords regularly.
Never use in or near water or in any environment
where electric shocks are possible.

INSTALLATION AND USE

Fit rubber feet and wheels underneath the base of
the unit as indicate (if not assembled).
Position the compressor on a flat surface or one
with a max. inclination of 10° in a well-ventilated area.
If the surface is sloping and smooth, make sure that
the compressor does not move while in operation.
If the compressor operates on a shelf or the edge
of a stand, ensure that it may not fall off by securing
it appropriately.
START-UP
Ensure that the knob situated in the upper part of
the compressor is turned to "0". Put the plug into the
power socket and turn the knob to "I".
Attach the rubber hose or the spiral type hose to
the appropriate fitting situated near the pressure swi-
tch.
The compressor operates completely automati-
cally and is controlled by the pressure switch which
stops it when the pressure inside the tank reaches
the maximum pressure and starts it again when the
pressure returns to the minimum level. The difference
in pressure is usually 2 bar (29 PSI).
After having connnected the compressor to the
electrical power supply line, load to the maxi-
mum pressure and check the correct efficiency of the
machine.
It is not always necessary to use the maximum
working pressure. On the contrary, a pneumatic tool
usually requires less pressure. Adjust the pressure
to the required level by turning the knob clockwise
to increase it and anti-clockwise to decrease it. The
pressure setting is shown on the pressure gauge of
the compressor.
Before servicing the compressor, make sure that:
-the power cable is unplugged from the electricity
supply.
-there is no pressure in the air receiver.
The compressor generates condensation that ac-
cumulates in the tank. The condensate must be drai-
ned from the tank at least once a week by opening
the condensate drain valve.
Be careful in case there is any compressed air
within the cylinder as the water could burst out with
110/120V
some force. Recommended pressure 1-2 bar max.
2,5 mm²
• Loss of air
This may be due to the poor seal of one of the fit-
tings.
Check all the fittings by wetting them with soapy
water. It is normal for the pressure to drop when the
compressor is not used, whatever the case (roughly
1 bar every 5 minutes).
• The compressor fails to start
If the compressor has difficulty in starting, make
sure that:
- all the wires are correctly connected.
- the mains voltage is efficient (plug connected
correctly, magneto-thermal switch, fuses unblown).
• The compressor fails to stop
If the compressor fails to stop when the maximum
pressure is reached, the tank safety valve will cut in.
It is necessary to contact your local authorised ser-
vice centre.
– Do not drill, weld or intentionally deform the com-
pressed air tank.
– Ambient temperature for correct operation of the
compressor is between 0°C and 25°C (max.45°C).
– When temporarily not in use, turn the switch to
"0" (OFF).
– Be aware that
some components of
the compressor such
as the head and deli-
