* S3 = intermittent operation without the impact of
the start-up. This means that during a period of 10
minutes, the maximum operating time is 50% (e.g.
5 minutes of work and 5 minutes of rest) , under
optimal environmental conditions (max. temp
25°C). Respecting these guidelines and the prescri-
bed maintenance intervals will allow the product to
work properly over time.

Mounting the air filter (Fig. A, B)
1. Remove the transport lid and replace them with
the supplied air filter (13) before using the com-
pressor.
2. Mount the air filter (13) by screwing the air filter
(13) clockwise into the air inlet (12) as shown
on figure B.
Installing the compressor
• The compressor should be installed in ventila-
ted and dry environment.
• Make sure the compressor is placed on the
horizontal and stable ground.
• Place the compressor on a flat surface or at a
maximum slope of 10°, in a well ventilated area,
protected against atmospheric factors and not
in explosive surroundings.
• If the surface area is sloping and smooth, make
sure that the compressor will not move when in
operation.
• For proper ventilation and effective cooling, it is
important that the compressor is positioned at
least 50 cm away from any wall or obstacle.
• 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.
