To reduce the risk of electric shock, this tool
has a polarized plug (one blade is wider than
the other) and will require the use of a
polarized extension cord. The plug will fit into
a polarized extension cord only one way. If the
plug does not fit fully into the extension cord,
reverse the plug. If the plug still does not fit,
obtain a correct polarized extension cord. A
polarized extension cord will require the use of
a polarized wall outlet. This plug will fit into the
polarized wall outlet only one way. If the plug
does not fit fully into the wall outlet, reverse
the plug. If the plug still does not fit, contact a
qualified electrician to install the proper wall
outlet. Do not change the equipment plug,
extension cord receptacle, or extension cord
plug in any way.
Avoid body contact with grounded surfaces
such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of
electric shock if your body is grounded.
Avoid Dangerous Environments - Don’t e
xpose power tools to rain or wet conditions.
Waterentering a power tool will increase the
risk of electric shock.

condition. When using an extension cord, be
sure to use one heavy enough to carry the
current your product will draw. A wire gauge
size (A.W.G.) of at least 16 is recommended
for an extension cord 50 feet or less in length.
A cord exceeding 100 feet is not
recommended. If in doubt, use the next heavier
gauge. The smaller the gaugenumber, the
heavier the cord. An undersized cord will cause
a drop in line voltage resulting in loss of power
and overheating.
Never use blades or flailing devices. Unit is
designed for line trimmer use only. Use of any
other accessories or attachments will increase
the risk of injury. Inspect area to be cut.

STARTING/STOPPING THE TRIMMER

See Figure 4 - 5, page i.

Attach the outlet end of an extension cord to the plug on
the rear of the string trimmer.

NOTE: Use only approved outdoor extension cords.

Route the extension cord through the slot located on
the rear of the string trimmer housing and place
underneath the cord retainer.

To start the string trimmer, press the switch trigger.
To stop the string trimmer, release the switch trigger.

If any parts are damaged or missing, please call
1-888-266-7096 for assistance.

OPERATING THE TRIMMER

See Figure 6, page i.

Folow these tips when using the string trimer:

Hold the trimmer with your right hand on the rear
handle and your left hand on the front handle.
Keep a firm grip with both hands while in operation.
Trimmer should be held at a comfortable position with
the rear handle about hip height.
Cut tall grass from the top down. This will prevent
grass from wrapping around the shaft housing and
string head.

If grass becomes wrapped around the string head:

Stop the trimmer.
Unplug the string trimmer.
Remove the grass.

THE CUTTING LINE

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.

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.

TELESCOPING BOOM AND FRONT HANDLE

See Figure 9, page ii.

The boom can be extended or shortened for ease of use.
Unplug the string trimmer.
Unscrew telescoping boom coupler and slide to desired
position.
Tighten boom coupler.

The angle of the front handle can be adjusted 180°.

Unplug the string trimmer.
Set the trimmer on a flat surface and turn the knob

counterclockwise to loosen the handle.

For trimming, adjust the handle upward.
For edging, adjust the handle downward.
Turn the knob clockwise until the handle is securely

tightened.

THREE-POSITION PIVOTING HEAD
