How to fix cavity slider?

Hi there, 

Recently we had new carpet installed in our 20 year old house. The new carpet is thicker than the old and has caused a problem with the cavity slider going into our walk in robe. During the carpet installation, the guys removed the slider to install the carpet. They put the slider back, but now the carpet and the bottom of the door are too close to use without damaging the new carpet. A builder friend came over to help with this problem, but wasn’t able to as he said you need a special type of flat spanner (?) to adjust or remove a cavity slider (He was able to help with another regular swing door that had the same problem). I’ve googled but this spanner doesn’t seem to be an easy thing to buy. 
Does anyone have any ideas about what I should buy? 
Per the photos, the door CAN close but is tighter to the carpet than I like, plus it’s been rehung but not square!
