• To facilitate the restart of the machine, it is          

important to press the pressure switch button so 

that it is first in the off position and then again in the 

on position. The machine is equipped with a pres-

sure switch with a vent valve with delayed closing 

(or a valve located on the non-return valve) which 

simplifies the start of the engine and it is therefore 

normal for air to blow out of the vacuum container 

for a few seconds.
• When connecting a compressed air tool to a     

compressed air hose from the compressor, it is    

absolutely necessary to interrupt the air flow from 

the compressed air hose.
• When using compressed air for different areas of 

use (air pumping, compressed air tools, painting, 

cleaning with water-based cleaners, etc.), the user 

must respect and have good knowledge of the     

applicable safety regulations for each area of   use.

Start and use

• Start by fitting wheels, the air cylinders of both 

cylinders and the crankcase ventilation / oil plug.

• Note before starting that the oil level must be 

checked! Always be sure to check the oil level, it 

should be kept in the middle of the transparent 

inspection glass. On some models, the oil level is 

checked with an oil dipstick. If necessary, top up 

with compressor oil (in cold rooms top up with SAE 

20 oil and in warm rooms top up with SAE 30 oil).
• Check that the electrical installation data matches 

the data specified on the compressor nameplate.
• Check that the button on the pressure switch       

located on the compressor is in the OFF position, 

then connect the plug of the supply cable to a 

grounded electrical outlet.
• In this mode, the compressor is ready for use.
• When you switch on the pressure switch, the    

compressor starts and pumps air into the tank. 

When the value for maximum operating pressure 

(set by the factory during the test run phase) is 

reached, the compressor stops and empties the    

remaining air that is in the block and in the supply 

pipe via a valve located under the pressure switch. 

This simplifies the next start, as there is no pressu-

re. When using air, the compressor restarts automa-

tically when the lower calibration value is reached 

(there is a difference of about 2 bar between the 

upper and lower calibration value). The pressure in 

the air tank can be checked using the manometer.
• The compressor automatically continues to      

operate with this cycle until the pressure switch 

switch is depressed. If you want to start the com-

pressor immediately after it has been switched off, 

wait at least 10 seconds before restarting it.

• The compressor is equipped with a pressure 

regulator. Using the knob (pull it outwards and turn 

clockwise to increase the pressure and turn coun-

terclockwise to reduce the pressure) the air pres-

sure can be regulated to optimize the use of the          

compressed air tools. When the desired value has 

been set, push the knob inwards to block it.
• You can check the set value on the manometer.
• Check that the air consumption and maximum 

operating pressure of the tool match the setting on 

the pressure regulator and the performance of the 

compressor.
• Switch off the machine, unplug it and empty the air 

tank when the work has been completed by opening 

the drain valve.
Corrosion must be prevented, depending on the 

conditions of use, condensation may have accumu-

lated inside the tank, which means that it must be 

emptied every day. You can do this by opening the 

drain valve on the tank.
A periodic service inspection of the air tank must 

be performed as the internal corrosion can reduce 

the thickness of the steel wall, which can lead to the 

tank bursting. All applicable local regulations must 

be followed. When the wall thickness reaches the 

minimum value indicated on the tank type plate (C), 

the lower air tank must not be used.
• The service life of the air tank depends mainly 

on the working environment. Avoid installing the     

compressor in dirty or corrosive environments, as 

this can drastically reduce the life of the vessel.
• Do not anchor the vessel or connected compo-

nents directly on the ground or on fixed structures. 

Equip the pressure with vibration dampers.
