Brabantia Rotary

I bought a replacement online, but can not work out how to put it. I can not see where the current begins and ends! Any clues??

Looks like a dry-arm 3 or 4. Look carefully at the arms, one arm should have two holes close together, then a gap, then two holes close togerther ... along the arms, while other weapons that single holes. Start over at the center hole on the arm with pairs of holes. then further through the center hole on the arm next, etc., until you return to the arm with pairs of holes. Thread the wire through the second hole of the first pair, the lead line to the center, in the first hole of the second pair, go around again as before. Finally, you arrive at the second hole of the pair of holes (and all holes on all arms line will pass by. Attach firmly to the hole. By the way, I found the plastic coated steel core line that works best (get your DIY store.)

it can be on one line end?
