Make sure that the compressor is
transported in the right way, do not turn it
upside down and don't lift it with hooks or
ropes (fig. 5-6).
Starting up
•
Check whether the mains voltage corresponds
to that indicated on the electrical specification
plate (fig. 10), the permitted tolerance range
should be within 5%.
•
Press the switch situated on the upper part
into the "0" position according to the pressure
regulator type fitted on the device (fig. 11).
•
Put the plug in the plug socket (fig. 9) and start
the compressor up by putting the switch of the
pressure regulator in the "I" position. The
operation of the compressor is fully automatic.
The pressure regulator will stop the
compressor when the maximum value has
been reached and start it up when the
pressure drops below the minimum value.
Normally the difference in pressure is approx.
2 Bar/29 psi between the maximum and the
minimum value. For instance - The
compressor will stop when it reaches 8 Bar
(116 psi) (this is the maximum operating
pressure) and will start up automatically when
the pressure within the tank has dropped to 6
Bar (87 psi).
The head/cylinder/transmission pipe
assembly may reach high temperatures,
so take care when working close to these
parts and do not touch them to avoid
burns (fig. 12 - 13).
Adjusting the operating pressure
Fig. 14
It is not necessary continuously to use the
maximum operating pressure, the compressed-air
tools often require less pressure. With regard to
compressors supplied with a pressure reduction
valve it is necessary to set the operating pressure
properly.
It is possible to set the operating pressure by using
the turning knob on the reduction valve.
•
By turning clockwise, the pressure will be
increased.
•
By turning anti-clockwise, the pressure will be
reduced.
The set pressure can be locked by turning the ring
under the turning knob in the opposite direction
from the turning knob thereby fixing the turning
Ferm
knob. The set pressure is visible on the
manometer of the reduction valve.
4. Maintenance
Make sure that the plug is removed from
the mains when carrying out maintenance
work on the motor.
The machines have been designed to operate
over a long period of time with a minimum of
maintenance. Continuous satisfactory operation
depends upon proper machine care and regular
cleaning. Before interfering in any way whatsoever
with the compressor, please make sure that:
•
The general line switch is in the "0" position.
•
The pressure regulator and the switches on
the switch board are switched off in the "0"
position.
•
The air tank is fully decompressed.
Malfunction
Should the machine fail to function correctly, a
number of possible causes and the appropriate
solutions are given below:
Air loss
•
May be caused by a poor seal of a connection.
•
Check all connections by wetting them with
soap and water.
The compressor runs but does not compress
Fig. 19
•
May be caused by the valves (C-C2) or a
gasket (B1-B2) being broken.
•
Replace the damaged part.
The compressor will not start
•
If the compressor is difficult to start, check:
•
whether the voltage of the mains corresponds
to that on the specification plate (fig. 10)
•
whether electrical extension cables are being
used with a faulty core or length.
•
whether the operating environment is too cold
(below 0°C).
•
whether there is electricity supply (plug
properly connected, magneto-thermal fuses
not broken).
The compressor does not shut off
If the compressor does not shut off when the
maximum pressure has been reached, the safety
valve of the tank will be activated. It is necessary
