NYLON CUTTING HEAD
The nylon cutting head is a dual line trimmer head that has bump & feed
mechanism.
The nylon cutting head feeds out the nylon cord after tapping the trimmer head
on the ground.
Operation
– The most effective cutting area is shown by the shaded area.
– To feed the nylon cord, increase the nylon cutting head speed to approx. 6,000
-1
min and tap the nylon cutting head lightly on the ground.
– 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
– Stop the engine.
– Press the housing latches inward to lift off the cover, then remove the spool.
– Hook the center of new nylon cord into the notch in the center of the spool,
with one end of the cord extending about 80 mm (3-1/8") more than the other.
Then wind both ends firmly around the spool in the direction of the head
rotation (left-hand direction indicated by LH and right-hand direction by RH on
the side of the spool).
– Wind all but about 150 mm (6") of the cords around the spool, leaving the ends
temporarily hooked through the notch on the side of the spool.
