Notes:
•
All hazards due to electrical discharges must be avoided. Never use the compressor if the
power cord or extension is damaged. The cables must be checked at regular intervals. Never
use the compressor in or near water or in the vicinity of hazardous environments that may
cause electrical discharges.
•
Avoid low temperatures below 0°C as this may prevent the engine from starting due to inertia.
Operation
•
Place the compressor close to the consumer to avoid long air and supply lines.
•
Make sure that the oil level is correct and that the air filter has been installed.

Pressure switch
Set the button
(1)
in the upper part of the pressure switch mounted on the unit to “off.” Insert the plug
into the socket and press the button
(1)
to “on.” The rubber or spiral hose must be attached to the con-
nector
(2)
next to the pressure switch.
Attention:
Make sure that compressed air lines are suitable for the maximum operating pressure of
the compressor. Never attempt to repair damaged/broken lines.
The operation of the compressor is fully automatic and controlled by the pressure switch. The pressure
switch stops the compressor when the maximum pressure in the tank is reached and restarts it when
the minimum pressure is reached. Normally the pressure difference between the maximum and min-
imum value is approx. 2 bar.
Example: The compressor stops when reaching 8 bar (maximum operating pressure) and starts auto-
matically when the pressure inside the tank has dropped to 6 bar. Check the correct function of the
pressure switch after connecting the compressor to the power line by means of a charging procedure.
Adjustment of the working pressure
It is not always necessary to work at maximum pressure. In most cases, the
pneumatic tool used requires less pressure.
For compressors equipped with pressure reducers, a correct adjustment of
the working pressure is required. This sets the desired pressure: Turn clock-
wise (+) to increase the pressure and counter-clockwise (-) to decrease it.
