How to String a Double String Trimmer


String trimmers provide the finishing touches to a well-manicured lawn. The string trimmer's cutting line tackles the hard work as it tears down weeds and grass. Thin lines have less cutting power and thicker lines can work a trimmer's motor too hard. Double lines cut more at a faster rate than single lines and can trim heavier areas of growth. When it's time to replace the line, usually as soon as you notice the trimmer not cutting as cleanly, it only takes a few minutes to re-thread two lines through the spool.

Step 1

Unscrew the spool by holding the string head and turning the spool counterclockwise.

Step 2

Grab and pull the old string from the spool to remove it.

Step 3

Cut two pieces of new string, measuring about 9 feet long, with a pair of scissors.

Step 4

Push the end of one string into the top spool's anchor hole. Turn it counterclockwise to wind it around the spool. Turn until only 6 inches of the string remains. Keep this string extending from the spool and place the string in the spool flange.

Step 5

Push the end of the other string into the bottom spool's anchor hole. Turn it counterclockwise to wind it. Turn until 6 inches of the string remains. Place the string in the spool flange.

Step 6

Place the spool and its retainer back on the trimmer.
