How do you replace line on echo gt200r weed eater?

To replace the line on an Echo GT-200R weed eater, first, turn off the machine and ensure it is disconnected from the power source. Then, remove the spool from the trimmer head by pressing the tabs or unscrewing it, depending on the model. Next, take a new length of trimmer line (typically 0.095 inches in diameter), cut it to the desired length, and insert it into the spool according to the direction indicated on the spool. Finally, rewind the line, reattach the spool to the trimmer head, and you're ready to go.
