• 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
other surfaces.
• In long growth, cut from the top down and do not
exceed 13" (330 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.
Cutting Line / Line Feeding
Your trimmer uses 0.065" (1.65 mm) diameter, round nylon
line. During use, the tips of the nylon lines will become
frayed and worn. Cutting line will wear faster and require
more feeding if the cutting or edging is done along sidewalks
or other abrasive surfaces or heavier weeds are being cut.
