Unscrew your handle knob cap off, and you will see a plastic piece still in the hole. Pull your handle assembly out of your reel from the opposite side. Stick the screw of your cap back in the hole you just unscrewed it out of and jiggle a little to get the plastic piece to come out onto your screw cap. Switch the screw cap with the plastic piece still on it to the other side of the reel. Place the handle assembly in the opposite side. Screw the handle knob back in tight and you are ready to go fishing.
