If your reel has a drag adjustment knob, you may want to turn it to increase the drag/resistence on the line as you strip it off your reel. If it is an older or less expensive reel without a drag adjustment, you will need to carefully strip the line off and wind it back on under tension.

Hope this helps and welcome to FAOL.
