WARNING
The product may start unexpectedly and cause inju-
ries and burns during cleaning, repair and mainte-
nance work.
– Switch the product off.
– Pull out the mains plug.
– Allow the product to cool.
– De-pressurise the compressor.
Note:
Release overpressure in the compressor by switching off
the compressor and using up the compressed air still in
the pressure vessel, e.g. with a compressed air tool run-
ning at idle or with an air blow gun.
12.1 Cleaning
• Keep protective devices, air vents and the motor
housing as free of dust and dirt as possible. Rub the
product clean with a clean cloth* or blow it off with
compressed air* at low pressure. We recommend that
you clean the product directly after every use.
• Clean the product 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 product. Make sure that no water can pen-
etrate the product interior.
• We recommend that you clean the product directly af-
ter every use.
• The hose and injection tools must be disconnected
from the compressor before cleaning. The compressor
must not be cleaned with water, solvents or similar.
12.2 Maintenance
Tool required:
• Phillips screwdriver*

12.2.1 Maintaining the air filter (1b) (Fig. 5)
DANGER
Risk of fire and explosion!
If not cleaned correctly, fuel may ignite and even ex-
plode. This can lead to severe burns or death.
– Only clean the air filter by knocking it out.
– Never clean the air filter with petrol or flammable
solvents.
ATTENTION
Risk of damage!
Operating the engine without a filter element or with a
damaged filter element can cause engine damage.
– Never run the engine without the air filter element or
with a damaged filter element. This would allow dirt
into the engine, which would result in severe dam-
age to the engine.

ATTENTION
Fouled air filters diminish the engine output
due to reduced air supply to the carburettor.
Regular inspection is therefore essential.
The air filter prevents dust and dirt being sucked in. It is
necessary to clean this filter at least every 300 operating
hours.
1. Remove the air filter cover (1) by removing the screw
(1a).
Use a Phillips screwdriver.
2. Remove the air filter (1b).
3. Only clean the air filter (1b) by knocking it out.
4. Replace a faulty air filter (1b) with a new one.
5. Insert the air filter (1b) and use the screw (1a) to fit the
air filter cover (1).
12.2.2
• The safety valve is set to the maximum permissible
pressure of the pressure vessel.
• It is not permitted to adjust the safety valve or remove
the connection lock 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 re-
quired.
1. To open the outlet of the safety valve (11), turn the
perforated drain nut (11a) anticlockwise. Now, the
valve audibly releases air.
2. Then, tighten the exhaust nut (11a) clockwise again.
12.2.3
ATTENTION
To ensure a long service life for the pressure vessel,
drain off the condensate after each use by opening the
drain screw.
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.
1. Release the vessel pressure beforehand (see 14.1).
2. Open the drain screw (8a) by turning it anti-clockwise
(looking at the screw from the bottom of the compres-
sor).
3. In order to drain the condensation water completely
out of the pressure vessel (8), it must be tilted slightly
to the side so that the drain screw (8a) is the lowest
point.
4. Then close the drain screw (8a) again (turn clock-
wise). Check the pressure vessel (8) for rust and dam-
age each time before use.
5. The compressor shall not be operated if the pressure
vessel (8) is damaged or rusty. If you discover dam-
age, please contact the customer service workshop.
