How to Install Weed Trimmer String


Your weed trimmer helps you enhance the appeal of your lawn and provides a crisp cut to fences, sidewalks and around landscaping. Keeping a trimmer running its best requires some routine maintenance. The string inside the trimmer must be changed when it has been reduced to a small stub or there is little left. The string wears down as the trimmer sweeps at weeds and tall grasses in the yard, making loading additional string a frequent task.

Step 1

Remove the spark plug wire from the spark plug to ensure the trimmer cannot start accidentally. Lay the trimmer on a table or flat surface and squeeze the sides of the trimmer head, where the string emerges from. Pull the trimmer head away from the trimmer base while squeezing the notches on the side of the head.

Step 2

Separate the head from the spool reel. The reel sits inside the trimmer head. Inspect the spool reel for the direction the string is loaded. Cut a section of string approximately 9 feet in length.

Step 3

Loop the string in half, placing the center of the string in the middle notch of the spool reel. Wind the string around the spool, placing the top string over the center ridge and the bottom string below the center ridge of the spool.

Step 4

Lock the string in place, pulling the top end into the notch on the outer edge of the spool reel. Repeat this process with the bottom string, pulling it tight to prevent the string from unraveling.

Step 5

Place the spool reel inside the trimmer head. Feed the string ends from the spool into the holes on each side of the trimmer head.

Step 6

Re-attach the trimmer head to the trimmer. Push the head onto the trimmer arm until it clicks, securing it in place. Replace the spark plug wire before starting the trimmer.
