are on each side of the cutting
head. (Fig. 18)
NOTE: It may be easier to press

by letting it pop off, or a
slight wiggle of the cap may
be required to pull it off the
outer spool (Fig. 19)
3. Remove any old line from the
inner reel or obstructions
from the outer spool. (Fig. 20)
4. Place the inner reel back into the
outer spool (Fig. 19).

and press down firmly until
both tabs snap back into
place. (Fig. 21)
