Switching Trimmer On and Off (Fig. A)
To turn the appliance on, squeeze the lock-off lever
then the variable speed trigger
release the variable speed trigger and the lock-off lever.

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
forward toward the auxillary handle
position. This mode is best for larger projects that require
more time to complete.
To accelerate the trimmer, pull the speed control switch
back toward the battery housing
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. G, H)
With the trimmer on, angle it and swing side to side as
shown in Figure G.
Maintain a minimum distance of 24 inches (610 mm)
between the guard and your feet as shown in Figure H.
WARNING:

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.

Bump Feed Trimmer Line Feed
Your trimmer uses 0.080 inches (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 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 13 inch (330 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 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 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.
MAINTENANCE (FIG. I)

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.
1. Keep the air intake slots
fig. I
2. 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.
3. Plastic parts may be cleaned by using a mild soap and
a damp rag.
4. The line cutter on the edge of the guard can dull over
time. It is recommended you periodically touch-up the
sharpness of the blade with a file.
Cleaning

WARNING: Blow dirt and dust out of all air vents with
clean, dry air at least once a week. To minimize the risk
of eye injury, always wear ANSI Z87.1 approved eye
protection when performing this.
20 clean to avoid overheating.
