start‑up can cause injury.

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.

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
toward the auxiliary handle
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. J, K)
Maintain a minimum distance of 610 mm between the guard
and your feet as shown in Figure J.
With the trimmer on, angle it and swing side to side as
shown in Figure K.

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.
Bump Feed Trimmer Line Feed
Your trimmer uses 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 350 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 300 mm high.
