• To return to trimming position, pull the flip-
to-edge collar down and rotate the head
clockwise back to its original position.
NOTE: You will experience faster than
normal cutting line wear if the trimmer line
is positioned directly over the sidewalk or
abrasive surface.
EDGING
WARNING:
Edger, stones, pieces of metal and other
objects can be thrown out at high speed by
the line. The trimmer and guard are
designed to reduce the danger. However,
MAKE SURE that other persons and pets
are at least 100 feet (30m) away. Optimum
cutting results are achieved on edges
deeper than 2 inches (50 mm).
• Do not use this trimmer to create trenches.
• Using the edging wheel (10), guide the
trimmer as shown in figure M.
• Position the edging wheel on the edge of the
sidewalk or abrasive surface so the cutting
line is over the grass or dirt area to be edged.
• To make a closer cut, slightly tilt the trimmer.

SPEED CONTROL & RUNTIME
EXTENSION MODE
This string trimmer gives you the choice to
operate at a more efficient speed to extend the
runtime for larger jobs, or accelerate the trimmer
speed for high-performance cutting (figure N).
• To extend runtime, pull the runtime
extender switch (5) back toward the
battery (13) into position #1. This mode is
best for larger projects that require more
time to complete.
• To accelerate the trimmer, push the

When being used as an
speed-control switch forward toward the
trimmer head (9) into position #2. This
mode is best to cut through heavier growth
and for applications that need higher RPM.
NOTE: When in acceleration mode (#2),
runtime will be decreased as compared to when
trimmer is in extended runtime mode (#1).

HELPFUL CUTTING TIPS
• Use the tip of the string to do the
cutting; do not force string head into
uncut grass. Use edge guide along such
things as fences, houses and flower beds
for best practices.
• Wire and picket fences cause extra string
wear, even breakage. Stone and brick walls,
curbs, and wood may wear string rapidly.
• Do not allow spool cap to drag on ground
or other surfaces.
• In long growth cut from the top down and
do not exceed 12 inches (304.8 mm) high.
• Keep trimmer tilted toward the area being
cut; this is the best cutting area.
• The trimmer cuts when passing the
unit from the right to left. This will avoid
throwing debris at the operator.
• Avoid trees and shrubs. Tree bark, wood
moldings, siding, and fence posts can
easily be damaged by the string.
CUTTING LINE / LINE FEEDING
Your trimmer uses .065 inch (1.65 mm)
diameter, ROUND nylon line. During use,
the tips of the nylon lines will become frayed
and worn and the special self feeding spool
will automatically feed and trim a fresh length
of line. 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. The advanced
automatic line feeding mechanism senses
when more cutting line is needed and feeds
and trims the correct length of line whenever
it's required. DO NOT BUMP unit on ground in
attempt to feed line or for any other purposes.
