Maintenance Treatments (Fig.J)
• Keep the air intake slots
26
clean to avoid overheating
(Fig.J).
• Your trimmer line can dry out over time. To keep your line
in top condition, store spare line in a plastic, sealable bag
with a tablespoon ofwater.
• Plastic parts may be cleaned by using a mild soap and a
damprag.
MAINTENANCE

WARNING: To reduce the risk of
serious personal injury, turn unit off and remove
the battery pack before making any adjustments or
removing/installing attachments or accessories. An
accidental start-up can causeinjury.
Bump Feed Trimmer Line Feed
Your trimmer uses 0.080" (2.0 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 beingcut.
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 willfeed.
NOTE: Extending nylon line beyond the 14" (355mm)
swath will negatively affect performance, runtime, and the
life of the trimmer due to potential of damaging motor.
Doing so may void thewarranty.
Helpful Cutting Tips
• 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
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" (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 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 thestring.
OPERATION

WARNING: To reduce the risk of
serious personal injury, turn unit off and remove
the battery pack before making any adjustments or
removing/installing attachments or accessories. An
accidental start-up can causeinjury.
To accelerate the trimmer, pull the speed control switch
back toward the battery housing
11
into the "HI" position.
This mode is best to cut through heavier growth and for
applications that need higherRPM.
NOTE: When in "HI" mode, runtime will be decreased as
compared to when trimmer is in "LO"mode.
Trimming (Fig.H, I)
With the trimmer on, angle it and swing side to side as
shown in Fig.I.
Maintain a minimum distance of 24" (610 mm) between the
guard and your feet as shown in Fig.H.

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 serious injury.
Installing and Removing the Battery Pack (Fig. F)
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.
Proper Hand Position (Fig.G)

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.

WARNING: Always use proper eye
protection that conforms to ANSI Z87.1 (CAN/CSA Z94.3)
while operating thisappliance.

WARNING: Remove the battery before
making any assembly, adjustments, or changing accessories.
Such preventive safety measures reduce the risk of starting the
TRIMMERaccidentally.

CAUTION: Before you begin trimming, only
use the appropriate type of cuttingline.

CAUTION: Inspect area to be trimmed
and remove any wire, cord, or string-like objects which could
become entangled in the rotating line or spool. Be particularly
careful to avoid any wire which might be bent outwardly into
the path of the appliance, such as barbs at the base of a chain
linkfence.
Proper hand position requires one hand on the primary
handle
14
and one hand on the auxiliary handle
4
.
Switching Trimmer On and Off (Fig.A)
To turn the appliance on, squeeze the lock‑off button
2
and then the variable speed trigger
1
.
To turn the appliance off, release the variable speed trigger
and the lock‑offbutton.

WARNING: Never attempt to lock the
trigger in the onposition.
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 extend runtime, push the speed control switch
3
forward toward the auxiliary handle
4
into the "LO"
position. This mode is best for larger projects that require
more time tocomplete.
