If the nylon cord does not feed out proceed as follows:
1. Release the control lever to run the engine idle and then squeeze the
control 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 with the above
procedure, 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 with procedure 2, rewind/replace the
nylon cord by following the procedures described under "Replacing the
nylon cord".
Replacing the nylon cord
– First, stop the engine.
– Press on 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 80mm (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 100mm (3-15/16") of the cords, leaving the ends tempo-
rarily hooked through a notch on the side of the spool.
– Mount the spool in the housing so that the grooves and protrusions on the
spool match up with those in the housing. Keep the side with letters on the
spool visible on the top. Now, unhook the ends of the cord from their
temporary position and feed the cords through the eyelets to come out of the
housing.
