Questions from a new Loricraft user

I just took delivery today of a new Loricraft PRC3 RCM. took it out of the box, went through the rough setup and cleaned a couple of records. Very impressed. Now my questions:

some of the nylon thread had come loose from the spool in shipment and I wound it rather sloppily back to the spool in my hurry to try it out. I decided to go back and rewind it evenly on to the spool. In doing so, I managed to pull the thread completely out of the arm. The manual seems pretty vague about how to rethread - merely saying that I should "disconnect the 3mm pipe and use the pump to rethread through the bottom brass tube" Do I disconnect from the arm, or from where the 3mm tube enters the discharge bottle? I've tried it a few different ways and even with the pump running, I can't get it to rethread. Any advice?

Second question: When cleaning, the arm tracks very nicely from the outside to the inside, picking up everything. But if I go from the lable side to the outside, the arm does not track at all, it just sits at the spot I place it. What am I doing wrong there?

Seems like an advanced RCM like this one would come with a better manual.....
