10. Cleaning, maintenance and storage
m Attention!
Pull out the mains plug before carrying out any clean-
ing and maintenance work! Risk of injury from electric
shock!
m Attention!
Wait until the equipment has cooled down completely!
Danger of burning!
m Attention!
Always depressurise the equipment before carrying
out any cleaning and maintenance work! Risk of injury!
10.1 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 any cleaning
products 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 disconnect-
ed from the compressor before cleaning. The com-
pressor must not be cleaned with water, solvents
or similar.
10.2 Maintenance of the pressure vessel (Fig. 7)
m Attention!
To ensure a long service life for the pressure ves-
sel (8), drain off the condensate after each use by
opening the drain screw (13).
Release the boiler pressure beforehand (see 10.7.1).
26 | GB
The drain screw is opened by turning it counterclock-
wise (when looking at the screw on the bottom of the
compressor) so that the condensate can be complete-
ly drained out of the pressure vessel. Then close the
drain screw again (turn clockwise). Check the pressure
vessel for rust and damage each time before use.
The compressor shall not be operated if the pressure
vessel is damaged or rusty. If you discover damage,
please contact the customer service workshop.
m Attention!
The condensate from the pressure vessel contains oil
residue. Dispose of the condensate in an environmen-
tally friendly manner at a suitable collection point.
10.3 Safety valve (Fig. 5)
The safety valve (14) is set to the maximum permissible
pressure of the pressure vessel. It is not permitted to
adjust the safety valve or to remove the connection lock
(14.2) between the drain nut (14.1) and its cap (14.3).
Actuate the safety valve every 30 operating hours but
at least 3 times a year to ensure that it works when re-
quired. Turn the perforated drain nut (14.1) anti-clock-
wise to open it, then pull the valve stem outwards by
hand via the perforated drain nut (14.1) to open the
safety valve outlet. Now, the valve audibly releases air.
Then turn the drain nut clockwise again to tighten.
10.4 Check the oil level at regular intervals (Fig. 3)
Place the compressor on a level and straight surface.
The oil level must be positioned between the MAX and
MIN of the oil sight glass (12).
Oil change: Recommended oil: SAE 15W 40 or equivalent.
The first oil filling must be changed after 10 operating
hours; afterwards, perform an oil change every 50 op-
erating hours.
10.5 Oil change (Fig. 2, 3)
Switch the motor off and unplug the mains plug from
the power outlet. Remove the oil plug (G). After re-
leasing any air pressure, you can unscrew the oil drain
screw (10) on the compressor pump.
To prevent the oil from running out in an uncontrolled
manner, hold a small metal chute under the opening
and collect the oil in a vessel. If the oil does not drain
out completely, we recommend tilting the compressor
slightly. Once the oil has fully drained out, replace the
oil drain screw (10).
