The clutches on greenfields are meant to be set correctly. As they wear they need to be reset to take up the slack. The friction material wears and the gap needs to be taken out.
I have never done it before but there are threads on it in here.
If you are not well equipped and confident i would suggest getting the dealer to do it. I would tend to think that if you are not up for servicing a machine its best to get this dealer done as well. They should know what they are doing and they have to warranty work for 3 months.
Having said that i am wondering why it got through serviceing without it coming to the attention of the servicee that the clutch needed adjustment. A question i would ask if i had to take it back 5 weeks later.
Yes it is possible that it ingested something and the clutch is damaged. Ive never heard of it before but it could be possible.
