Never use the appliance with bare feet or wet hands or feet.
Never pull the power cable to disconnect the plug from the socket or to move the
compressor.
Never leave the appliance exposed to adverse weather conditions.
Never transport the compressor with the receiver under pressure.
Do not weld or machine the receiver. In the case of faults or rusting, replace the entire
receiver.
Never allow inexpert persons to use the compressor. Keep children and animals at a
distance from the work area.
Do not position flammable or nylon/fabric objects closed to and/or on the compressor.
Never clean the compressor with flammable liquids or solvents. Check that you have
unplugged the compressor and clean with a damp cloth only.
The compressor must be used only for air compression. Do not use the compressor for
any other type of gas.
The compressed air produced by the compressor cannot not be used for pharmaceutical,
food or medical purposes except after particular treatments and cannot be used to fill the
air bottles of scuba divers.
5.3
Things you should know
To avoid overheating of the electric motor, this compressor is designed for intermittent
operation as indicated on the technical dataplate (for example, S3-25 means 2.5 minutes
ON, 7.5 minutes OFF). In the case of overheating, the thermal cutout of the motor trips,
automatically cutting off the power when the temperature is too high. The motor restarts
automatically when normal temperature conditions are restored.
To facilitate restart of the compressor, in addition to the operations indicated, it is
important to return the button of the pressure switch to the OFF position and then to ON
again (figures 2-3-4).
On certain «V» type versions, the reset button on the terminal box of the motor must be
pressed (fig. 5).
On three-phase versions, simply return the button of the pressure switch to the ON
position. (fig. 3).
Single-phase versions are fitted with a pressure switch equipped with a delayed closing air
discharge valve which facilitates start-up of the motor. Therefore venting of air from this
valve for a few seconds with the receiver empty is normal.
All the compressors are fitted with a safety valve that is tripped in the case of
malfunctioning of the pressure switch in order to assure machine safety.
When fitting a tool, the flow of air in output must be switched off.
When using compressed air, you must know and comply with the safety precautions to be
adopted for each type of application (inflation, pneumatic tools, painting, washing with
water-based detergents only, etc.).
6 START-UP AND USE
Fit the wheels and foot (or the suckers according to model) following the instructions
provided in the packaging.
Check for correspondence between the compressor plate data with the actual
specifications of the electrical system. A variation of ± 10% with respect of the rated value
is allowed.
Insert the plug of the power cable in a suitable socket (fig. 6) checking that the button of
the pressure switch located on the compressor is in the OFF «O» position.
For lubricated models, check the oil level using the rod included in the oil fuel plug (figures
7a-7b-7c) or the sight glass (fig. 7d), and if necessary top up.
At this point, the compressor is ready for use.
Operating on the switch of the pressure switch (fig. 3), the compressor starts, pumping air
into the receiver through the delivery pipe.
