CONTROLLING TRIMMER HEAD SPEED
The throttle trigger controls the speed at which
the trimmer head turns Squeeze the throttle
trigger more firmly for faster cutting speed
Use the lowest pressure required to cut the
material This helps to maximize the amount of
cutting time per battery charge and reduces the
number of charging operations required
ADVANCING TRIMMER LINE
The GSL disk lasts longer than typical trimmer
lines However, the trimmer line will wear down
over time Advance the line by bumping the
head against the ground to get more line out of
the disk
With the motor running and the trimmer head
turning, bump the trimmer head on the ground
(Fig 14) More trimmer line comes out of the
disk, and excess trimmer line is cut off by the
line cutting blade on the bottom of the guard
FIG. 14
If the trimmer line does not come out, the disk
may be empty Turn off the trimmer/edger and
replace the disk as described in "Replacing the
GSL Disk"

Operating the Trimmer/Edger
Trimming
Trimming cuts grass and weeds that are
close to walls, fences, and other areas too
small to reach with a lawn mower, down to a
manageable height but not down to soil level
Assume proper grip and stance, then start the
trimmer Squeeze the throttle trigger until the
trimmer head achieves the minimum speed
necessary to cut the grass or weeds
Angle the trimmer head slightly toward the
direction of the cut (Fig 15)
FIG. 15
Push the trimmer head slowly from the side
into the grass or weeds to be cut, and move
the trimmer head back and forth so that the
end of the trimmer line contacts the material
to be cut
Do not allow the trimmer line to touch the
ground
5–10°
