THE CUTTING LINE
,A
• t, 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
See Figure 7, page L
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.
[] 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.
[] 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 steps1
through 3 in "Removing the Spool" on page 9).
If the line is tangled or jammed, untangle and replace
the line. If the spool is empty, replace the spool.
A
WARNING: To avoid injury, ALWAYS turn off and
disconnect the trimmer from the power outlet BEFORE
installing parts or cleaning the trimmer or making any
adjustments.
CUTTING TiPS
See Figure 8, page iL
[] Keep the trimmer tilted toward the area being cut; this is
the best cutting area.
[] The string trimmer cuts when passing the unit from left
to right. This will avoid throwing debris at the operator.
Avoid cutting in the dangerous area shown in figure 8.
[] Use the tip of the string to do the cutting; do not force
string head into uncut grass.
[] Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may
wear strings rapidly.
[] Avoid trees and shrubs. Tree bark, wood moldings,
siding, and fence posts can easily be damaged by the
strings.
