How to Install Trimmer Line


Trimmer line in a weed trimmer requires attention at every usage. The line becomes worn down as it cuts and tears away at tall grass and weeds. A weed trimmer makes landscaping tight areas a breeze when your mower just won't fit. Restringing the trimmer is a must when the line no longer advances during use.

Step 1

Disengage the engine. Remove the spark plug wire from the spark plug.

Step 2

Turn the trimmer head counterclockwise to remove it. Pull it apart from the trimmer base. The line is located inside the trimmer head.

Step 3

Measure and cut 10 feet of replacement trimmer string. Bend the ends of the new trimmer string to form a hook. Loop the hooked ends into the eyelet hole on the trimmer head. One end of the string goes in each eyelet hole. Wind the string around the trimmer head in the direction printed on the side of the head.

Step 4

Pull the string ends into the cut out on each side of the trimmer head, locking the string into place.

Step 5

Place the string ends protruding from the trimmer head through the eyelet holes in the trimmer base. Re-attach the trimmer head to the base, turning it clockwise until it clicks into place. Place the spark plug wire onto the spark plug to restart the trimmer.
