your body. Correct positioning of the tool allows for
maximum control and will reduce the risk of serious
personal injury caused by kickback. (Fig. 26)

until a click is heard. Make sure that it cannot be taken off
with pulling it off. Hang the tool as shown.
Adjust the strap length so that the cutter blade will be kept
parallel with the ground at the level of 10 to 30 cm above
the ground.

Replacing the nylon cord
WARNING:
• Always be sure that the tool is switched off and
battery cartridge is removed before attempting to
perform inspection or maintenance on the tool.
Failure to switch off and remove the battery cartridge
may result in serious personal injury from accidental
start-up.
• 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. (Fig. 33)
Press inward on the housing latches and lift upward to
remove the cover. Discard any of the remaining nylon
cord. (Fig. 34)
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 80mm longer than the other side.
Wind both ends firmly around the spool in the direction
marked on the head for left hand direction indicated by
LH. (Fig. 35)
Wind all but about 100 mm of the cords, leaving the ends
temporarily hooked through a notch on the side of the
spool. (Fig. 36)
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. (Fig. 37)
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.
