We have had 2 new Stihl vacs wrecked by dust getting into the engine over the past 18 months. Never had the problem before, used their equipment for many years and carry out the usual maintenance.
The latest machines appear more powerful and the design of the air filter has changed(for the worse?).
Sthil replaced the first machine FOC, the second they rebuilt and we paid them£90.00. They say they have not come across this before and blame us - anyone else had a similar problem?
