Troubleshooting - Scheppach SG4500 Betriebsanleitung

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.

Lors de la remise en service après un entreposage prolongé
1
Changer l'huile moteur.
2 Remplir d'essence fraîche avant de démarrer à nou-
veau le moteur après la période d'entreposage.
Si le moteur n'a plus fonctionné plus d'un mois, la quali-
té de l'essence modifiée peut rendre difficile le démar-
rage du moteur ou avoir d'autres conséquences. Pour
empêcher cela, dévisser le bouchon de vidange du car-

robinet d'essence pour que l'essence puisse s'écouler
du réservoir.
