Things You'll Need
0.065-inch string
Knife or scissors
Tape measure
The Weed Eater RTE115C is an electric-powered weed trimmer. You can replace the string by reloading the old spool with new trimmer string or by installing a pre-loaded spool. Reloading an old spool is cost effective but takes more time. The process for replacing the string is not overly difficult regardless of the method you choose. If you use replacement string, only use 0.065-inch string or else you could damage your trimmer.
Pre-wound Spool
Step 1
Twist the cap off the spool by turning it counterclockwise. This cap holds the spool and trimmer guide onto the trimmer shaft.

Step 2
Remove the string guide and then pull the spool off the trimmer shaft.
Step 3
Discard the old spool and slide the new spool onto the trimmer shaft.
Step 4
Unwind 4 to 6 inches of string from the spool and thread it through the guide.
Step 5
Place the guide onto the spool and thread the cap into place to lock both the guide and spool onto the trimmer shaft.
