4. Pull the starter rope out slowly so that the oil
distributes itself in the engine and screw the spark
plug back in.
5. Remove all dirt, deposits and dust from the engine
and the cylinder head ridges.
6. Clean the air filter or replace it if it is very dirty.
7. Disconnecting the battery
8. Store the power generator securely in a dry place
that is inaccessible to children.
9. The unit may not be stored in the open.
10. Cover the unit and the engine to protect against
dust and store in a clean, dry place.
When re-commissioning after a long period of
storage
1. Change the engine oil.
2. Fill with fresh petrol before starting the motor after
the storage period.
If the engine is not used for more than one month,
changes to the petrol quality may result in difficulties
starting the engine or in other issues. To prevent this,
loosen the carburettor's drain screw and allow the
petrol to run out. Also open the fuel valve so that the
petrol drains from the tank.

Dispose of the drained oil properly at a local used oil
collection point. Dumping used oil in the soil or mixing
it with waste is prohibited.

Switch off the engine and allow it to cool.
Caution! Danger of burning
Clean or replace spark plug as required:
1. Remove the spark plug connector (d) and clean
any dirt from the spark plug area.
2. Unscrew the spark plug and check it.
3. If there is any damage, e.g. cracks or chips,
replace the spark plug.
4. Clean the spark plug electrodes with a wire brush.
5. Check and set the electrode gap.
6. Screw the spark plug in and tighten with the spark
plug spanner.
7. Place the spark plug connector (d) on the spark
plug.
When replacing, ensure that no dirt gets into the
cylinder head.
Check the fit of the spark plug. A loose spark plug can
cause damage to the engine by overheating.
Pulling too hard can damage the thread in the cylinder
head.
The manufacturer is not responsible for the resulting
damages; the user solely bears the risk. Only use the
recommended spark plugs or identical spark plugs.
Clean the air filter (fig. 1 + 9)
1. Release the brackets (b)
2. Remove the air filter cover (9).
3. Clean the foam pre-filter (c) a non-flammable
solvent.
Attention: Do not use petrol or cleaning solvents with
a low flash point to clean the air filter element. This
could result in fire or explosion.
4. Squeeze the pre-filter in order to remove the
solvent/soapy water.
5. Rinse the washed filter element with clean water.
6. Allow the filter elements to dry thoroughly.
7. Replace the filter cover and tighten the clamps (b).
If the engine is operated in very dusty environments,
clean the air filter daily or after every ten operating
hours.
Never run the engine without an air filter or with a
damaged air filter. This would allow dirt into the engine,
which would result in severe damage to the engine.
