NYLON CUTTING HEAD

The nylon cutting head is a dual line trimmer head that has bump & feed mechanism 

or auto feed mechanism (ultra auto) (country specific).

The nylon cutting head with bump & feed mechanism feeds out the nylon cord after 

tapping the trimmer head on the ground. The nylon cutting head with auto feed 

mechanism automatically feeds out the nylon cord by the changes in centrifugal 

force.

Operation

The most effective cutting area is shown by the shaded area.

 and tap the nylon cutting head lightly on the ground. With auto feed 

mechanism, trigger action can feed the nylon cord.
If the nylon cutting head does not feed out by tapping, rewind/replace the nylon 

–

cord by following the procedures described under “Replacing the nylon cord.”

Replacing the nylon cord (BUMP & FEED)

WARNING: Make sure that the cover of the nylon cutting head is secured to the 

housing properly as described below. Failure to properly secure the 

cover may cause the nylon cutting head to fly apart resulting in serious 

personal injury.

Press inward on the housing latches and lift upward to remove the cover.

Discard any of the remaining nylon cord.

Hook the middle of the new nylon cord to the notch located at the center of the spool 

between the 2 channels provided for the nylon cord. One side of the cord should be 

about 80 mm longer than the other side.

Wind both ends firmly around the spool in the direction marked on the head for left 

hand direction indicated by LH.

Wind all but about 100 mm of the cords, leaving the ends temporarily hooked 

through a notch on the side of the spool.
