  • Tim from HOLLISTER, CA
  • Really Easy
  • 30 - 60 mins
  • Socket set
Removed the 2 bolts holding the gear head to shaft. On my model I had to remove the complete trimmer head, then using 2 wrench take the trimmer head adapter off the gear heD. One video showed simply putting a screwdriver in the notch behind trimmer head and unscrewing complete head. Mine of course was slightly more involved but still qui te easy once I saw what needed to be done.
