Replacing the nylon cord
(For ultra auto 4)
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 80 mm (3-1/8") more than the other.
(left-hand direction indicated by LH and right-hand direction by RH on the side
of the spool).
Wind all but about 100 mm (3-15/16") of the cords, leaving the ends temporarily
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.
Align the protrusion on the underside of the cover with the slots of the eyelets.
