Titan SDS drill stops working intermittently

[jon92]

I've had a Titan TTB278SDS for about 2 years, has always worked fine but just recently it conked out while I was using it. Strangely, it works if the chuck is pointing upwards but if it is pointing downwards the drill won't start at all and is completely dead (whether rotating or hammering). Anyone guess what needs fixing please? I have already replaced the carbon brushes and the trigger switch which hasn't made any difference.
Thank you.

Flex has a break, most likely where the flex enters the handle of the drill.

Thanks I will give it a wiggle and see what happens.

You were absolutely right, I cut out the dodgy bit of cable and now working perfectly. Thank you very much.

I had a Bosch SDS with the same.

It happened over the years because when I stored the drill.in the case, the flex was curved inside the case.
