It’s under warranty, don’t take it to bits.
Superstar story- I got a KS i900 from them. Arrived, it didn’t work properly- stuck in position pretty much all the time. They said oh, give it a quick service, it’ll be fine. So I did, and it wasn’t fine, it was exactly the same. So sent it back and they said “You caused the problem when you serviced it, we’ve fixed it now but it’s your fault”. Though as it turned out, they hadn’t fixed it at all.
But! After the second return, they actually did fix it, and since then it’s been brilliant- it’s had one proper service, but other than that it’s just been wipedowns and sprays with lube and occasionally lifting the top ring to clean and grease underneath- 2 minute stuff.
