OPERATION
Use the tip of the line to do the cutting; do not force bump
head into uncut grass.
Wire and picket fences cause extra line wear, even
breakage. Stone and brick walls, curbs, and wood may
wear line rapidly.
Avoid trees and shrubs. Tree bark, wood moldings,
siding, and fence posts can easily be damaged by the
line.
SAFETY GUARD LINE TRIMMING CUT-
OFF BLADE (FIG. 7)
This trimmer is equipped with a line trimming cut-off blade (49)
on the safety guard. For best cutting, advance line until
it is trimmed to length by the cut-off blade. Advance line
whenever you hear the engine running faster than normal.
This will maintain best performance and keep line long
enough to advance properly.
