Troubleshooting - Scheppach SG3500 Anleitung

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, chan-
ges 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.
