6. OPERATION
Adjusting the operating pressure
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 pressure regulator turning knob(5) on
the reduction valve.
• By turning clockwise, the pressure will be increased.
• By turning anti-clockwise, the pressure will be reduced.
Note: After starting up, please confirm that if the pressure switch could be able to cut off power
when it reaches the factory maximum closing pressure. When the pressure exceeds 8.8bar,
the safety valve should be able to open the deflation. Otherwise, the pressure switch or safety
valve should be replaced. If needs to be replaced, please contact the service address on the
warranty card, change them by professionals.
The compressor has two pressure gauges and one point to connect an air hose:
• Pressure gauge (7) on the right: outlet pressure. The pressure of this outlet can be regulated
with help of the pressure regulator (5).
• Pressure gauge(8) on the left: tank pressure
Hints for accurate adjustment of the pressure regulation:
• Turn the pressure regulator turning knob (5) anti-clockwise till pressure is fully released
• Connect the air tool you want to use to the quick coupler (6)
Starting up
• Check whether the mains voltage corresponds to that indicated on the electrical
specification plate , the permitted tolerance range should be within 5%.
• Press the switch (3) situated on the upper part into the “0” position according to the pressure
switch type fitted on the device .
• Put the plug in the plug socket and start the compressor up by putting the switch(3) 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 theminimum value. For instance
- The compressor will stop when it reaches 8 Bar (this is the maximum operating pressure)
and will start up automatically when the pressure within the tank has dropped to 6 Bar .
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.
