Removing and replacing the trimmer head

If the trimmer head is cracked or broken, it should be removed and replaced with a new one. Also, if there is buildup of clippings between the trimmer head and the guard, it is easier to clean them if the trimmer head is removed first.

Insert a screwdriver into the trimmer head lock above the guard to keep the spindle from turning (Fig. 29).

Important: Make sure all three tabs are in position and that the cover is level and well- seated (Fig. 28).

•Turn the trimmer head by hand and make sure the cover rotates evenly. If it rotates unevenly, remove and replace the cover so it is level with the rest of the trimmer housing.

Turn the trimmer head counter-clockwise until it comes off of the spindle (Fig. 30).

To replace, with the screwdriver still in the hole, thread the head onto the spindle and turn clockwise until it stops.
