Should I smell clutch burning on brand new 56 RC E weed trimmer?

I put Stihl synthetic oil in it ,ran about 15 min,let it cool,then ran again and was trimming heavy weeds at full power.
Didn't hear motor slipping but smelt the clutch burning a bit and after I shut it down just a minute from first sniff I could smell burnt clutch if I put my nose close to motor.
Smelling the clutch burning has me a bit concerned,especially when it's still on its first tank.
Sometimes brakes seat in and maybe clutch may smell for a while but if it's not normal what other signs should I look for if the clutch is defective in a brand new trimmer.
