How to rope-threading platinum tail-end 170/190/240

Put rope end 1 through inner hole (direction: inside >> outside)

Tie a knot at the rope end 1 - Attention: leave approx. 10mm rope left after the end of the knot

Pull hard at the other end of the rope so that the knot slipps into the recess of the plastic part

Put rope end 2 through the outer hole (direction: inside >> outside)

Tie two knots at rope end 2 - Attention: leave approx. 10mm space between the knots

Put the rope-loop over the propeller-disk (Attention: use the small recess at the propeller)

Turn the propeller by 180 degree (against clockwise direction) until the rop-loop completely snaps under the propeller
