WARNING:
Always be sure that the tool is
switched off and battery cartridge is removed
before attempting to perform inspection or main-
tenance on the tool. Failure to switch off and remove
the battery cartridge may result in serious personal
injury from accidental start-up.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.
Replacing the nylon cord
WARNING:
Use nylon cord with diameter
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
injury.
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.
1. Press on the housing latches inward to lift off the
cover, then remove the spool.

cord. Fold the new nylon cord with one end become
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 (left-hand direction indicated by LH
on the side of the spool).

notch on the side of the spool.

4. 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.
