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.
1. Press on the housing latches inward to lift off the
cover, then remove the spool.

approximately 80 mm (3-1/8") longer than the other
end. Then hook the new nylon cord into the notch in the
center of the spool.
Wind both ends firmly around the spool in the direction
of the head rotation (right-hand direction indicated by
RH on the side of the spool).
