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.

WARNING:
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
and
Your trimmer uses 0.080 inches (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 15 inch (380 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 (305 mm) high.
