6. Clean the air filter or replace it if it is very dirty.
7. Store the generator securely in a dry place that is
inaccessible to children.
8. The unit may not be stored in the open.
9. Cover the unit and the engine to protect against

When re-commissioning after a long period of
storage

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.
