THE CUTTING LINE

THE CUTTING LINE

EXTENDING THE CUTTING LINESee Figure 7, page i.CUTTING TIPS 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.

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.

EXTENDING THE CUTTING LINE

See Figure 7, page i.

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.

See Figure 8, page ii.TELESCOPING BOOM AND FRONT HANDLESee Figure 9, page ii. 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 ii.

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.
