Speed Control Switch (Fig. A)
This Grass 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.
To extend runtime, push the speed control switch
4
forward
toward the auxiliary handle
5
into the "LO" position. This mode
is best for larger projects that require more time tocomplete.
To accelerate the trimmer, pull the speed control switch back
toward the battery housing
12
into the "HI" position. This mode
is best to cut through heavier growth and for applications that
need higherRPM.
NOTE: When in "HI" mode, runtime will be decreased as
compared to when trimmer is in "LO"mode.
Trimming (Fig. A, E, F)
With the trimmer on, angle it and swing side to side as shown
in FigureE.
Maintain a minimum distance of 610 mm between the guard
and your feet as shown in FigureF.
WARNING: Keep the rotating string roughly
parallel with the ground (tilted no more than 30 degrees).
This trimmer is not an edger. DO NOT TILT the trimmer so
that the string is spinning near a right angle to the ground.
Flying debris can cause seriousinjury.
Bump Feed Trimmer Line Feed
Your trimmer uses 2.032 mm diameter nylon line. Cutting line
will wear faster and require more feeding if the cutting is done
along sidewalks or other abrasive surfaces or heavier weeds are
beingcut.
As you use the trimmer, the string will get shorter due to wear.
Gently bump the trimmer on the ground while running at
normal speed and the line willfeed.
NOTE: Extending nylon line beyond the 330mm swath will
negatively affect performance, runtime, and the life of the
trimmer due to potential of damaging motor. Doing so may
void thewarranty.
Helpful Cutting Tips
• Use the tip of the string to do the cutting; do not force string
head into uncutgrass.
• Wire and picket fences cause extra string wear, even
breakage. Stone and brick walls, curbs, and wood may wear
stringrapidly.
• Do not allow spool cap to drag on ground or othersurfaces.
• In long growth, cut from the top down and do not exceed
304.8 mmhigh.
• Keep trimmer tilted toward the area being cut; this is the
best cuttingarea.
• The trimmer cuts when passing the unit from the left to
right. 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 thestring.
