I bought the brand new Festool planer with a curved knife. The knife left its housing after 10 'of use. No injuries, luckily. Notified by email on June 18, Festool Belgium's customer service, foresaw to examine the machine, considers it unnecessary to answer me until then.
I have a new plane HL 850 EB-Plus model which nobody dares to use ...
Congratulations again
However the representative ended up introducing himself, and convincing me of the conformity of the product. Without being able to explain the damage observed.
Also I change my rating.
