Just curious? Did you read the plethora of posts about the Kapex motors failing before you imported such an expensive tool without a warranty?
No, I did not. Can you explain? Which motors are problematic? All? The 50hz in particular?
There has been a lot of reports of failing motors on US model Kapex KS120. Festool does not acknowledge any systematic problem. However, based on anecdotal evidence Kapex stands out among other tools in that respect. So, after all you might be better off with imported model. I would trust Rick with his advise. He is an electrical engineer and a former Festool employee consultant.
I agree 100% that Rick's advice is correct and I wasn't questioning that, but it is a separate and independent point to the faults.
As to the faults I believe it's more than anecdotal, whilst we don't have an official response or numbers, the observed reports of failed Kapex motors on this forum is significantly higher than any other tool and that's a big deal considering it's one of their more expensive tools sold in lower volume than, for example, the TS 55.
To the OP, basically any 110v motor is considered by many to effectively be a ticking time bomb of pending failure. Festool have been mostly silent on the issue apart from one suggestion that repeated quick cuts in thin stock might be the issue, which is a bit of an issue for a highly accurate trim saw, designed for repeat cuts; as opposed to a work horse saw designed for cutting 2x12.
