2010 North Rebel Safety Adjustment
In the Euro parts of the world there apparently was a little issue that resulted in the 5th line pull through not releasing easilly. It seems that when seated and not cleaned the 5th can be very dirty above the metal ring and get difficult to pull through.
Pull through the 5th line at the ring end, and tie a knot per the diagram so that it will not pull through and in the position marked in the diagram
then let out the 5th to make up for the line you just shortened per the next diagram. Jobs done, sweet as.
Always wash your Iron Heart III out completely with fresh water and pull the line through to check it is smooth.
As a note check the chicken loop and loop line is not adversly worn, replace if necessary.
