breakage. Stone and brick walls, curbs, and wood may wear
string rapidly.
• In long growth, cut from the top down and do not exceed
12" (305 mm) high.
• Keep brush cutter head tilted toward the area being cut; this
is the best cutting area.
• The brush cutter cuts best 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 blade.
