Helpful Cutting Tips (Fig.I)
• 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.
Line Feed Button (Fig.A)
The line feed feature allows you to advance the length of
cutting line available whiletrimming.
• To extend the cutting line, fully depress the line feed
button
16
while trimming and thenrelease.
NOTE: The trimmer will stop cutting when the line feed
button is pressed and will resume cutting whenreleased.
NOTE: For maximum line length, press the button multiple
times until you hear the cutting line hitting the guard. Do not
continue to press the line feed button once the maximum
length is reached. This will result in overfeeding and will
consume stringquickly.
Speed Control Switch (Fig.A)
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.
To accelerate the trimmer, push the speed control
switch
3
forward toward the auxillary handle
4
into the "HI"
position. This mode is best to cut through heavier growth
and for applications that need higherRPM.
To extend runtime, pull the speed control switch back
toward the battery housing
11
into the "LO" position. This
mode is best for larger projects that require more time
tocomplete.
NOTE: When in "HI" mode, runtime will be decreased as
compared to when trimmer is in "LO"mode.
Edging Mode Operation (Fig. A)

WARNING: When being used as an 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' (30 m) away. Optimum cutting results are achieved on
edges deeper than 2" (50mm).
• Do not use this trimmer to createtrenches.
• Using the edge guide
17
, guide thetrimmer.
• Position the edging guide 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.
2. To return to trimming position, Press the convert‑to‑edge
button
15
and rotate the motor housing
5
180°
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.
Convert to Edging Mode (Fig.A)

CAUTION: The edge guide should only be
used when in the edging mode.

WARNING: Remove the battery pack from
the power source before making anyadjustments.
The trimmer can be used in trimming mode or edging mode
to trim overhanging grass along lawn edges and flowerbeds.
To convert the trimmer to edging mode:
1. Press the convert‑to‑edge button
15
and rotate the
motor housing
5
180° counterclockwise, until the motor
housing snaps into edgeposition.
Trimming (Fig.J, K)
With the trimmer on, angle it and swing side to side as
shown in FigureJ.
Maintain a cutting angle of 5° to 10°. Do not exceed 10°.
Cut with the tip of the line.
Maintain a minimum distance of 24" (610 mm) between the
guard and your feet as shown in FigureK.
Switching Trimmer On and Off (Fig.A)

WARNING: Never attempt to lock the
trigger in the onposition.
To turn the appliance on, squeeze the lock‑off button
2
and then the trigger
1
. Once the unit is running, you may
release the lock‑off button. To turn the appliance off, release
thetrigger.
Proper Hand Position (Fig.I)

WARNING: To reduce the risk of serious
personal injury, ALWAYS use proper hand position
asshown.

WARNING: To reduce the risk of serious
personal injury, ALWAYS hold securely in anticipation
of a suddenreaction.
Proper hand position requires one hand on the main
handle
14
and one hand on the auxiliary handle
4
.
Installing and Removing the Battery Pack
(Fig.H)
NOTE: For best results, make sure your battery pack is
fullycharged.
To install the battery pack
12
into the tool handle, align the
battery pack with the rails inside the tool’s handle and slide it
into the handle until the battery pack is firmly seated in the
tool and ensure that it does notdisengage.
To remove the battery pack from the tool, press the release
button
13
and firmly pull the battery pack out of the tool
handle. Insert it into the charger as described in the charger
