How to Thread a Craftsman Sim-Pull Weedwacker®

Craftsman's Sim-Pull Weedwacker® trimmer allows you to trim a yard in the small spaces where you can't use a lawnmower. The Sim-Pull feature makes this model easier to start than other models; you only need to pull the starting rope gently to start the unit. The Craftsman Weedwacker® has a small combustible engine to power the rotating trimmer head that uses trimmer line for cutting grass and weeds. The line is rotated quickly to allow proper cutting action. When the line becomes too short, you tap the head of the trimmer on the ground to release more line. Craftsman's Sim-Pull Weedwacker® will occasionally require new trimmer line as the line is depleted during operation.

  1. 1

    Move the on/off switch to the off position to turn off the trimmer. Locate the spark plug at the rear of the engine. The spark plug will stick out of the unit an inch or more. Gently pull the spark plug wire off the spark plug, using your fingers.

  2. 2

    Tilt the trimmer up so the line spool is easier to access. Pull firmly on the tap button located on the bottom of the spool and remove the spool.

  3. 3

    Replace the spool with a new pre-wound spool, or cut two pieces of trimmer line, using scissors. The line pieces should each be 12 1/2 feet long. Insert one end of each line into the small holes located on the inside of the spool.

  4. 4

    Locate the arrow on the spool, indicating which direction the line should be installed. Wrap the line tightly around the spool until 3 to 5 inches remain. Push the line into the small notches in the spool.

  5. 5

    Insert the line ends into the exit holes on the trimmer hub. Push the spool onto the hub until it locks in place. Pull the lines from the outside of the hub to release them from the spool notches.

  6. 6

    Gently push the spark plug wire onto the spark plug. Start the trimmer to test the new line.

Tips and warnings

  • Only use trimmer line in your trimmer head. Other material such as rope, wire or string can break loose and cause damage to the machine and the operator.
