Removing Old Trimming Line and Obstructions
1. When the trimming line runs out, the last piece should
automatically eject from the cutting head. If it does not, push the
bump knob down and pull the remaining line out of the cutting
head.
2. If the line will not come out or the cutting head is otherwise
obstructed:
a. Firmly press a tab on the cutting head with your thumb (Fig. 23).
DO NOT press the tab with a screwdriver or other object.
b. Continue pressing the tab. Insert a flat-head screwdriver into
the gap between the outer spool and tab (Fig. 23).
c. Gently tilt the screwdriver to unlock the tab from the hole (Fig. 24).
d. Repeat the previous steps for the other tab.
e. Remove the spool cover (Fig. 24). DO NOT attempt to remove
any other parts of the cutting head.
f. Remove any old trimming line and/or obstructions.
g. Use a clean cloth to clean the inner reel, outer spool and spool
cover (Fig. 24).
h. Align the tabs on the spool cover with the holes on the outer
spool (Fig. 24). Push the spool cover onto the outer spool until
the tabs securely snap into the holes.
