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.
Take off cover from housing, pressing two latches which
are slotted section oppositely on side of housing. (Fig. 28)
Cut a nylon line in 3-6 m. Fold the cutting line in two
halves, leave one of half longer 80-100 mm than another.
(Fig. 29)
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.
Wind both ends firmly around the spool in the direction
marked on the head for left hand direction indicated by
LH. (Fig. 30)
Wind all but about 100 mm of the cords, leaving the ends
temporarily hooked through a notch on the side of the
spool. (Fig. 31)
Mount the spool on the cover so that the grooves and
protrusions on the spool match up with those on the
cover. Now, unhook the ends of the cord from their
temporary position and feed the cords through the eyelets
to come out of the cover. (Fig. 32)
Align the protrusion on the underside of the cover with the
slots of the eyelets. Then push the cover firmly onto the
housing to secure it. Make sure the latches fully spread in
the cover. (Fig. 33)
Replacing the blade for plastic blade
(Fig. 34)
Replace the blade when it is worn out or broken.
