I have read the instructions on rethreading the twist and edge rte 115 but it still doesn't make any sense. Do you have instructions with pictures?

see the video instructional and proceed with common sense and logically. God bless you

I found this solution on the net. I hope it helps.

Unscrew cap and remove. Remove line guide ring. Note which way to put line guide ring back on, slot to outer edge. Remove the empty spool.

Don't take spool apart unless you need to get inside to remove string. The outer half should be yellow. Cut 25 ft. of .065 line. Start pushing the line inside the spool from the center making sure the string is winding inside in a counter clock direction which should be shown on the spool. Keep pushing until there is about only 6 in. left.

Replace spool. Then the line guide ring, making sure to pull the string through the middle of it. Then hold the string on the slot in the ring while replacing the cap.

You can find the Poulan and Weed Eater instructions and manuals at InstructionSheets.com.

Here is a link to the page where you can download the Weed Eater RTE 115 Trimmer Manual.

The nylon string is simply spun onto the emty spool. There should be an arrow on the top of the spool indicating the direction to wind the line. If the spool is missing a notch to hold the line to get started, use your finger to hold it in place for a few full wraps.
