Maintenance - DeWalt XR LI-ION DCMASST1 Original Instructions Manual


WARNING: Keep the rotating string roughly parallel
with the ground (tilted no more than 30 °). 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 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
380 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.
