Craftsman 172.74544 - Manual (Page 20)

/K WARNING: DO NOT grasp the exposed cutting line when picking up
or holding the trimmer.
A single 0.065-inch round cutting line is pre-installed on the trimmer. When the cutting line
needs replacing, install a new pre-wound spool, Craftsman 71-85967.
EXTENDING THE CUTTING LINE (Fig. 13 and 13a)
During operation, cutting lines shorten due to normal wear. For greater convenience and
efficiency, your trimmer has been equipped with a bump feed head that allows you to
simply bump the trimmer head to extend the cutting lines while the trimmer is operating.
Cutting line will wear faster and require more feeding if the cutting or edging is done along
sidewalks or other abrasive surfaces or heavier weeds are being cut.
1. While the trimmer is on and spinning, gently bump the spool housing on a firm surface
(hard ground or sidewalk). This should release additional cutting line from the spool.
2. If no line is released, bump the trimmer head more sharply
or try bumping it on a firmer surface.
If there is no change in the cutting line length,
un-plug the trimmer’s pigtail power cord
from the extension cord. After the trimmer
head stops rotating, gently pull at the cutting
lines manually. Once the lines are pulled out
(extended), plug the trimmer’s pigtail power cord
into the extension cord and resume cutting.
If the cutting line still does not feed from the
spool, the spool might be empty or the
cutting line may be tangled or jammed on
the spool. Un-plug the trimmer’s pigtail
power cord from the extension cord.
After the trimmer head stops rotating,
remove the spool (see steps
1 through 3 in “Removing the
Spool” on page 20).
If the line is tangled or
jammed, untangle and
replace the line (see
page 20). If the spool is
empty, replace the
spool (see
page 20-21
