4. Drop the 2 drive heads to the lower position
5. Take off the front panel by grabbing the bottom, pulling down gently
6. Lay the panel flat above the drive heads (be careful the hoses are still connected)
7. Unscrew the handle for the drive head you want to replace
8. Using needle-nose pliers, remove the 2 E-clips above the drive head by lifting the drive head slightly and grabbing the clips from the back side
