(For Bump & Feed type)
First, stop the engine.
Press on the housing latches (1) inward to lift off the cover (2), then remove the
spool.
Hook the center of new nylon cord into the notch in the center of the spool (1),
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 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.
Then pu sh cover firmly onto the housing to secure it.
