This is about clutch problems. The most "harmless" failure is the clutch adjustment of the clutch. In order to eliminate it, it is sufficient to regulate the drive by itself by means of two ghake on the cable.
It's also possible to get clutch. In such a case, it is necessary to wash it well with the solvent and remove the oil from the box or engine.
If the problems are due to chaining, the basket or sub-unit must be replaced.
