The Automatic Feed Spool (AFS) is the technologically advanced line feed system found on Black & Decker string trimmer products. Using centrifugal force, the system monitors the amount of line being used and feeds more line automatically as the cutting line shortens.
How do you remove electric trimmer heads?
Pull the trimmer line spool out of the trimmer head. Observe your trimmer head to see if it has a small hole in the inner and outer portions. If so, insert a small Phillips screwdriver into the two holes to hold it in position, remove the center nut with an adjustable wrench and pull the head off.
