Things You'll Need
25 feet of .08 diameter line
While professionals choose a heavy-duty model that is built to handle serious weed whacking on a daily basis, many homeowners find the lightweight, inexpensive and easy-to-operate Featherlite Trimmer from Weed Eater to be perfect for handling their lawn-trimming needs. The unit requires little maintenance other than gas, but occasionally you will have to replace the cutting line. The easiest way to do that is to buy a replacement spool. But with a little effort, you can reload your existing spool and save a few bucks.
Grasp the tap button firmly and pull to remove the spool. Wipe the surface of the hub and spool.
Cut the 25-foot length of .08 diameter line in half with the scissors. Insert 1/2 inch of each line into the small holes on the inside of the spool.
Observe the direction of the arrows located on the spool. Wind the lines tightly into the spool in the direction of the arrows until only 3 to 5 inches remain. Push the lines into the notches on the spool.
Push the end of the lines through the exit holes in the hub. Pull the lines outside the hub to remove slack from the lines.
Line up the notches with the exit holes in the hub. Push the spool back into place in the hub until it snaps into place. Tug the lines firmly to free them from the notches.
Only use manufacturer-approved line. Never use wire, which could break and become a dangerous missile.
