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

•Load trimmer line as described in “Replacing trimmer line”.

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.

•Remove the battery, then disassemble the trimmer head as described in “Disassembling the trimmer head”.

•Insert a standard screwdriver into the slot on the spindle to hold it in place (Fig. 29).

FIG. 29

•Hold the screwdriver steady to prevent the spindle from turning, then turn the trimmer head counter-clockwise until it comes off of the spindle, then remove the screwdriver (Fig. 30).
