NYLON CUTTING HEAD
The nylon cutting head is a dual string trimmer head capable of both automatic
and bump & feed mechanisms.
The nylon cutting head will automatically feed out the proper length of nylon cord
by the changes in centrifugal force caused by increasing or decreasing rpms.
However, to cut soft grass more efficiently, bump the nylon cutting head against
the ground to feed out extra cord as shown in operation section.
Operation
– Increase the nylon cutting head speed to approx. 6,000 min
Nylon cord will not feed out correctly at lower speeds (under 4,800 min
– The most effective cutting area is shown by the shaded area in the diagram to
the right.
If the nylon cord does not feed out automatically, follow the instructions below:
1. Release the throttle lever so that the engine idles, and then squeeze the
throttle lever fully. Repeat this procedure until the nylon cord feeds out to the
proper length.
2. If the nylon cord is too short to feed out automatically using the procedure
above, bump the knob of the nylon cutting head against the ground to feed
out the nylon cord.
3. If the nylon cord does not feed out using procedure 2, 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.
