Cutting attachments

1. Use an applicable cutting attachment for the job
in hand.
− Nylon cutting heads (string trimmer heads)
are suitable for trimming lawn grass.
− Metal blades are suitable for cutting weeds,
high grasses, bushes, shrubs, underwood,
thicket, and the like.
− Never use other blades including metal multi-
piece pivoting chains and flail blades. It may
result in serious injury.
2. Always use the cutting attachment guard properly
suited for the cutting attachment used.
3. When using metal blades, avoid "kickback" and
always prepare for an accidental kickback. See
the section "Kickback."
Kickback (Blade thrust)
1. Kickback (blade thrust) is a sudden reaction to a
caught or bound cutting blade. Once it occurs, the
tool is thrown sideway or toward the operator at
great force and it may cause serious injury.
2. Kickback occurs particularly when applying the
blade segment between 12 and 2 o'clock to solids,
bushes and trees with 3 cm or larger diameter.
