part of the tool into aliquid.
Lubrication
Your power tool requires no additionallubrication.
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)
Maintain a minimum distance of 610 mm between the guard
and your feet as shown in FigureH.
With the trimmer on, angle it and swing side to side as shown
in FigureI.

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.
• 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
Your DeWALT power tool has been designed to operate
over a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper tool
care and regularcleaning.
