Replacing the nylon cord
WARNING: Make sure that the cover of the nylon cutting head is secured
to the housing properly as described below. Failure to properly
secure the cover may cause the nylon cutting head to fly apart
resulting in serious personal injury.
Press inward on the housing latches and lift upward to remove the cover.
Discard any of the remaining nylon cord.
Hook the middle of the new nylon cord to the notch located at the center of the
spool between the 2 channels provided for the nylon cord. One side of the cord
should be about 80 mm longer than the other side.
Wind both ends firmly around the spool in the direction marked on the head for
right hand direction indicated by RH.
Wind all but about 100 mm 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. 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 push cover firmly onto the housing to secure it. Make sure the latches fully
spread in the cover.
