1.3 INTENDED USE
The models described in this manual are designed and
manufactured for intermittent use with a maximum
service factor of 30% (e.g. 3 minutes of work and 7 min-
utes of rest), under optimal environmental conditions
(max. temp 25°C). Respecting these guidelines and the
prescribed maintenance intervals will allow the product
to work properly over time.
1.4 GROUND CONNECTION
The single-phase compressor is equipped with an elec-
trical cable and a two-pole + earth plug.
It is recommended not to make any other connections
on the pressure switch.
Repairs must always be carried out by a qualified
technician.
1.5 USE OF AN EXTENSION CABLE
Only use extension cables with plug and ground
connection. Do not use damaged or crushed exten-
sion cords. An extension cable that is to thin can cause
voltage drops, loss of power and overheating of the unit.
The extension cable must have a cross-section propor-
tionate to its length.

WARNINGS
Avoid all risks of electric shock. Never use the compres-
sor with a damaged electrical cable or extension cord.
Check all electrical cables on a regular basis. Never use
the compressor in or near water or near a hazardous
environment where electric shocks are possible.
Note:
The information in this manual is provided to
assist the operator in operating and maintaining the
compressor.

those of your compressor.

WITHOUT PRIOR NOTICE WHERE NECESSARY
2.1 INSTALLATION
Remove the compressor from its packing, make sure it is
in perfect condition and that it was not damaged during
transport, and
carry out the following operations:
• Fit the wheels and/or the rubber tab.
• Place the compressor on a flat surface, or with a slope
of no more than 10°, in a well-ventilated place, protect-
ed against atmospheric agents and in a non-explosive
environment.
• MAKE SURE THAT THE COMPRESSOR IS TRANSPORT-
ED PROPERLY, DO NOT OVERTURN IT OR LIFT IT WITH
HOOKS OR ROPES.
• If positioned on an inclined plane, make sure that the
compressor does not move and, if necessary, block the
wheels with appropriate means. If placed on a bracket
or shelf top, make sure that the support can bear the
weight and secure it properly so that it cannot fall.
• To ensure proper ventilation and effective cooling, the
compressor must be at least 50 cm away from any wall
or obstacle.
2.2 ELECTRICAL CONNECTION
The compressors are supplied with an electrical cable
and a two-pole + earth plug. The compressor must be
connected to grounded power socket protected by a
suitable differential switch (magneto-thermal).
2.3 START-UP
Check that the mains power matches the power indicat-
ed on the electrical data-plate. The permissible tolerance
range is +/-5%.
• Insert the plug into the power outlet and start the
compressor by turning the pressure switch knob
(5)
to
the “I / ON” position.
• The compressor is fully automatic, and is controlled by
the pressure switch which stops it when tank pressure
reaches the maximum value and restarts it when it
falls to the 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
– maximum operating pressure) and restarts automat-
ically when the pressure in the tank drops to 6 bar (87
psi).
After connecting the compressor to the power line, load
it to maximum pressure and check that the machine
works properly.
Some models are equipped with a head discharge valve,
which facilitates the subsequent start-up. In this case, a
puff of air is normal when the motor stops.
