line to ensure that it's undamaged.
If it is OK rewind it and insert the

spool hub as shown in figure 13.
Pull 4 in. (10 cm) of the line through
the hole and maintain tension while
placing the spool down into the
hub with the arrow up, as shown in
figure 14.

the tool on. In a few seconds or less
you'll hear the nylon line being cut
automatically to the proper length.

SOLUTION
• Check that the spool housing can rotate
freely. Carefully clean it if necessary.
• Check that the cutting line
does not protrude more than
approximately 5-3/8 inches
(136mm) from the spool. If it
does, cut it off so that it just
reaches the line trimmingblade.
• If the tool still runs slowly, stop using
the tool and take it to a service center.
• More line is fed when the line
shortens to approximately 3 inches
(76.2mm). To determine if the line is
not feeding, let line wear past this point.
• Keep the tabs depressed and
remove the spool from the spool
housing in the trimmer head.
• Ensure that the line is not
crisscrossed on the spool as
