Bosch 24v SDS drill stops spinning help please

[happyhero]

Hi, can anyone help me please? I have a 24v Bosch SDS drill and when I put a large bit in it so its really having to work, usually on hammer, sometimes it will carry on hammering but stop spinning as if its too much effort and I have to back off and go in with less pressure to keep it spinning.

I thought it was a clutch slipping, maybe its getting old, had it a few years but someone said to me that you use that tube of grease that you get in the case. You put it somewhere round the chuck and it doesn't happen any more.

Can anyone enlighten me? Where's the grease for? Does the grease cure that problem? Why does it seem to slip and not spin?

Any help appreciated.

grease is mainly for the chuck. could be the clutch has worn too much?

Thanks for the links very helpfull but as much as I look I cannot figure out which bit is the clutch to see if what it costs and if its worth replacing.
