3. It is easier to start the compressor again when the pump first becomes depressurised.
Once the air begins to be consumed, the compressor will start automatically when the lower
calibration value is reached (there are approximately 2 bar between the upper and lower
limit). The pressure inside the tank can be read on the gauge (picture 4).
4. The compressor will automatically stop and start alternately in this manner until the pressure
switch is pressed (pictures 5a, 5b, 5c and 5d). Wait at least 10 seconds after the compressor
has stopped before restarting.
5. Use the compressor’s pressure reducer to regulate air pressure and optimise the use of
pneumatic tools. Air pressure is controlled by using the knob which opens the valve (pull up
and turn clockwise) to increase pressure and closes it (pull up and turn counter-clockwise)
to reduce pressure (picture 7). Once the air pressure is set correctly, press the knob again.
6. The set value can be read on the pressure gauge (picture 8).
7. Check that the air consumption and maximum working pressure of the compressed air
tool conforms to the set pressure of the pressure regulator and the amount of air that the
compressor can deliver.
8. When the work is completed, turn the compressor off, disconnect the compressor from the
mains supply and empty the air from the tank.
MAINTENANCE
NB Before maintenance begins, set the pressure switch to the off position, disconnect the compressor
from the mains supply, remove the plug and drain the air from the tank completely.
• The lifetime of the compressor is dependent on the manner in which maintenance is performed.
• Make sure all screws (especially on the pump) are secure and tight (picture 9). This check must
be performed before starting the compressor for the first time, and then before the first
strenuous use. This is important as the tightening torque of the screws can change due to
thermal expansion.

• Clean the suction filter as often as is necessitated by the working environment, but at least every
100 hours. Replace the filter if necessary (a clogged filter reduces compressor capacity, while an
ineffective filter increases wear) (Pictures 10a and 10b).
• Change the oil after the first 100 hours and then every 300 hours. Check the oil level regularly.
