Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or

specified in "SPECIFICATIONS" only. Never use
heavier line, metal wire, rope or the like. Use rec-
ommended nylon cord only, otherwise it may cause
damage to the tool and result in serious personal

end. Then hook the new nylon cord into the notch in the
center of the spool.

of the head rotation (left-hand direction indicated by LH

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.
