It would appear that Festool doesn't care about their perceived reputation with regards to Kapex.
They seemingly feel:
1. Nothing is wrong
2. You are obviously using it incorrectly if English is your native language.
3. Their sales of Kapex are sufficient , and the line of lambs long , so as to make it unprofitable to address a problem real or perceived. If there is problem.
Which there's not - see number 1.
It's been at least six months, maybe longer since the brass came on here and said they're looking into it. Not one peep from anyone official regarding this , yet people keep reporting this tool's maladies in disproportionate number to anything else on here.
I cannot believe that that a company that has positioned themselves at the top of the heap can't find the engineering prowess to work out what's causing this saw's motor to fail in such a short timespan. I could believe they have and wouldn't want to disclose for fear of breaking the bank.
