Mcculloch Chainsaw Trimmer Head

This is a replacement knob for a trimmer. The plastic bump knob, which is connected to a spring, is used to secure the spool. A bump knob on a trimmer may get stuck or seized and will need a replacement. Before replacing the bump knob, remove the wire from the spark plug to avoid the accidental starting of the engine. Pull off the trimmer head housing and then use a flat head screwdriver to detach the old knob. Rotate it and then remove the component. Make sure the spring is in place then align the knob before rotating and snapping it in place. Take note that pulling the knob off may take extreme force when pulling. Some knobs are screw-mounted and a counterclockwise turn is necessary to unscrew it.
