T18 random pitch changes
« on: June 13, 2021, 06:24 AM »
Hi,

Wondering if this is a problem or "they all do that". My t18+3 seems to have a feint change in pitch/sound when driving. Most noticeable at torque 16 and above and doesn't matter what gear or whether I'm even driving a screw.

I don't want to send it in if they all do it...

My older generation c18 doesn't do it at all. And assume they have the same electronics, anyone else had this?

Thanks,
Ben.

It's the electronics that regulate speed and try to maintain a constant speed/torque. It is perfectly normal for Festool drills, as long as it's just a slight change in pitch
