Bosch has issued a recall for faulty PSS sanders, Serial No 786xxxxxx - 788xxxxxx (Green Series) due to 'Risk of mechanical failure resulting in injury and electric shock'. http://www.electricalsafetyfirst.org.uk/product-recalls/2016/01/bosch-pss-series-sanders/ https://www.sandercare.com/bundles/app/pdf/sicherheitshinweis_en_UK.pdf
Surprised - the second link states it is ones manufactured in 2007, if they have only now developed a fault it is quite a interesting but also quite impressive that they are still supporting these nearly 10 years on
It wouldn't look good for Bosch, if a few diyer's got frazzled, & Bosch knew about the fault & did nothing about.
More surprised by the timeline -most faults become apparent within the first year. Agreed most DIY's probably don't use them that intensively or frequently. Strange how its only now becoming apparent and widespread enough to warrant a recall
