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 disconnected
from the compressor before cleaning. The com-
pressor must not be cleaned with water, solvents
or similar.
10.2 Maintaining the pressure vessel (fig. 1)
Attention! To ensure a long service life for the
pressure vessel (8), drain off the condensate af-
ter each use by opening the drain screw (10).
Release the boiler pressure beforehand (see 10.7.1).
The drain screw is opened by turning it counter-
clockwise (when looking at the screw on the bottom
of the compressor) so that the condensate can be
completely 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 environ-
mentally friendly manner at a suitable collection point.
10.3 Safety valve (fig. 3)
The safety valve (17) is set to the maximum permissi-
ble pressure of the pressure vessel. It is not permitted
to adjust the safety valve or remove the connection
lock (9b) between the exhaust nut and its cap.
Actuate the safety valve every 30 operating hours but
at least 3 times a year to ensure that it works when
required. Turn the exhaust nut counterclockwise to
open it and pull the valve rod outwards over the ex-
haust nut to open the outlet of the safety valve. 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. 11)
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 equiv-
alent.
The first oil filling must be changed after 10 operat-
ing hours; afterwards, perform an oil change every
50 operating hours.
10.5 Oil change (fig. 1, 10, 11)
Switch the motor off and unplug the mains plug from
the power outlet. Remove the oil plug (15). After re-
leasing any air pressure, you can unscrew the oil
drain screw (12) on the compressor pump (13).
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 recom-
mend tilting the compressor slightly. Once the oil has
fully drained out, replace the oil drain screw (12).
Dispose of the old oil at a drop-off point for old oil.
To fill in the correct quantity of oil, make sure that the
compressor stands on an even surface. Fill the new
oil into the oil filler hole (18) until the oil level reaches
the maximum fill quantity. This is marked with a red
dot on the oil-level window (12) (fig. 11). Do not ex-
ceed the maximum filling quantity.
Overfilling the equipment may result in damage. Re-
insert the oil plug (15) into the oil filler hole (18).
10.6 Cleaning the intake filter (fig. 3, 12, 13)
The intake filter prevents dust and dirt being sucked
in. It is necessary to clean this filter at least every 300
operating hours. A blocked intake filter significantly
reduces the compressor power.
Remove the intake filter (2x) by opening the screw
(E).
Then pull off the filter cover (D). You can now remove
the air filter (F). Carefully knock out the air filter, fil-
ter cover and filter housing. These components must
then be blown out with compressed air (approx. 3 bar)
and reassembled in reverse order.
10.7 Storage
m Attention!
Pull out the mains plug and ventilate the equip-
ment and all connected pneumatic tools. Store
the compressor in such a way that it cannot be
used by unauthorised persons.
m Attention!
Store the compressor only in a dry location
which is not accessible to unauthorised per-
sons. Always store upright, never tilted! Oil may
leak out!
10.7.1 Releasing overpressure
Release overpressure in the compressor by switch-
ing off the compressor and using up the compressed
air still in the pressure vessel, e.g. with a compressed
air tool running at idle or with an air blow gun.
10.8. Transport
Use the transport handle (1) to transport the device,
and drive the compressor with it.
When lifting the compressor, note its weight (see
Technical data).
Ensure that the load is well secured when transport-
ing the compressor in a motor vehicle.
