12.1 Cleaning
• Keep the device as free of dust and dirt as possible.
Rub the device clean with a clean cloth or blow it off
with compressed air at low pressure.
• We recommend that you clean the device directly
after every use.
• Clean the device at regular intervals using a damp
cloth and a little soft soap. Do not use aggressive
cleaning agents or solvents; they could attack the
plastic parts of the device. Make sure that no water
can penetrate the device interior.
• The hose and injection tools must be disconnected
from the compressor before cleaning. The com-
pressor must not be cleaned with water, solvents or
similar.
12.2 Maintaining the pressure vessel (fig. 1)
Attention!
To ensure a long service life for the pressure vessel (2),
drain off the condensate after each use by opening the
drain screw (1).
Release the vessel pressure beforehand (see 12.6.1).
Open the drain screw (1) by turning it counterclock-
wise (when looking at the screw from the bottom of the
compressor) so that the condensate can be completely
drained out of the pressure vessel (2).
Then close the drain screw (1) again (turn it clockwise).
Check the pressure vessel (2) for rust and damage
each time before use.
Do not use the compressor with a damaged or rusty
pressure vessel (2). If you discover damage, please
contact the customer service workshop.

12.3 Safety valve (fig. 1)
The safety valve (15) has been set for the highest
permitted pressure of the pressure vessel (2). It is not
permitted to adjust the safety valve (15) or remove the
connection lock (15b) between the exhaust nut (15a)
and its cap (15c). Actuate the safety valve (15) every
30 operating hours but at least 3 times a year to ensure
that it works when required.
Turn the perforated exhaust nut (9a) counterclockwise
to open it and use your hands to pull the valve rod out-
wards over the perforated exhaust nut (9a) to open the
outlet of the safety valve (9). Now, the valve audibly
releases air. Then, tighten the exhaust nut (9a) clock-
wise again.
12.4 Cleaning the air filter
The air filter (13) prevents dust and dirt being sucked
in. It is essential to clean this air filter (13) after at least
every 300 hours in service. A blocked air filter (13) sig-
nificantly reduces the compressor power.
Turn the air filter (13) counterclockwise to remove it.
Open the filter cover and remove it. You can now take
out the filter element. Carefully tap out the filter element
, the filter cover and the filter housing. These compo-
nents must then be blown out with compressed air (ap-
prox. 3 bar) and reassembled in reverse order.
