Replacing the nylon cord (BUMP & FEED)
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 the latches (1) on the housing (2) inwards and lift upward to remove
the cover (3).
2. Release the nylon cord from the eyelet. And remove the spool (4) from the
cover. Discard any of the remaining nylon cord.
3. Hook the middle of the new nylon cord to the notch (5) located at the center
of the spool between the 2 channels.
One side of the cord should be about 80 mm (3") longer than the other side.
Wind both ends firmly around the spool in the direction of arrow mark on the
spool.
4. Wind all but about 100 mm (4") of the cords, leaving the ends temporarily
hooked through notches (6).
5. Mount the spool in the cover as holding notches meet the eyelets (7).
Unhook the ends of the cord from their temporary position and feed the
cords through the eyelets.
