speed after turning the tool on.
18. When using a cutting blade, swing the tool
evenly in half-circle from right to left, like
using a scythe.
19.
Hold the tool by insulated gripping surfaces
only, because the cutter blade may contact
hidden wiring. Cutter blades contacting a "live"
wire may make exposed metal parts of the tool
"live" and could give the operator an electric shock.
20. Do not start the tool when the cutting tool is
tangled with cut grass.
21. Before starting the tool, be sure that the cut-
ting tool is not touching the ground and other
obstacles such as a tree.
22. During operation always hold the tool with
both hands. Never hold the tool with one hand
during use.
23. Do not operate the tool in bad weather or if
there is a risk of lightning.
Cutting tools
1. Do not use a cutting tool which is not recom-
mended by us.
2. Use an applicable cutting attachment for the
job in hand.
Nylon cutting heads (string trimmer heads)
and plastic blades are suitable for trimming
lawn grass.
Cutting blades are suitable for cutting weeds,
high grasses, bushes, shrubs, underwood,
thicket, and the like.
Never use other blades including metal

3. Only use the cutting tool that are marked with
a speed equal or higher than the speed marked
on the tool.
4. Always keep your hands, face, and clothes
away from the cutting tool when it is rotating.

5. Always use the cutting attachment guard prop-
erly suited for the cutting attachment used.
6. When using cutting blades, avoid kickback
and always prepare for an accidental kickback.
See the section for Kickback.
7. When not in use, attach the blade cover onto
the blade. Remove the cover before operation.
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.
Fig.2
3. To avoid kickback:
1.
Apply the segment between 8 and 11 o'clock.
2. Never apply the segment between 12 and
2 o'clock.
3. Never apply the segment between 11 and
12 o'clock and between 2 and 5 o'clock,
unless the operator is well trained and
experienced and does it at his/her own
risk.
4. Never use cutting blades close to solids,
such as fences, walls, tree trunks and
stones.
5. Never use cutting blades vertically, for
such operations as edging and trimming
hedges.
