take the cowling cover off (it should twist off backwards) then put the handle in a upright position then grip both the handle and reels stem firmly take hold of the winder cap and twist away from you (clockwise)and remove it then grip the spool and turn it backwards to release it stick a pencil through the hole and pull the old line off,pass the loose end of your new line through the cowling & tie it onto your spool,put the spool back onto the reel (twist to lock) re-grip the handle and reels stem and screw the winder cap back on (anti-clockwise) don't over tighten just hand tight will do ! re-fit the cowling with the line passing through it,put the reel onto a rod butt,get some one to hold the new lines spool with a pencil through its hole and wind on the new line.
