  1. 1

    Lay your line trimmer down on a working surface.

  2. 2

    Unscrew the knob halfway down the metal shaft. The knob is there to allow the machine to take attachments. If your trimmer doesn't have a knob on the shaft, it cannot take attachments. Pull the two pieces of shaft apart.

  3. 3

    Unplug the two lines inside the shaft. One line is the electric wire that allows the motor to spin the attachment. The other is to help keep the attachment in line. After unplugging the lines, pull the two pieces of shaft apart, carefully. You don't want to damage the wires.

  4. 4

    Rest the brush cutter attachment against the opening of the shaft. Replug the wires into the brush cutter.

  5. 5

    Match the holes up for the knob and screw the knob back in.

Tips and warnings

  • The wires might take a little pulling to remove, especially if you have never unplugged them before.
  • Don't have the motor running while you install the attachment.
