It began with the fact that the engine of the mower always had often short dropouts.
At first I thought even that is the cause of the misfire in lawnmowers.
Yesterday the motor stopped permanently.
On closer examination the Schwabe 60262 Rubber extension a loose connection was found just behind the connector as the cause.
That might not actually happen in a highly flexible rubber extension.
After just over 2 years - with a use of a total of about 60 days - the line is already useless!
A disappointing quality.
