Operation
1. Only use the machine in good light and visi-
bility. Use in the dark or poor visibility area may
cause unexpected accident.
2. Avoid using the machine when it is hard to
keep your balance, for example, working on a
steep surface or windy day.
3. During operation, never stand on an unstable
or slippery surface or a steep slope. During
the cold season, beware of ice and snow and
always ensure secure footing.

thrown or become entangled in the cutting
attachment. Foreign particles may damage the
cutting tool and can cause dangerous kickback.
6. To control the machine steadily, do the follow-
ing during operation:
—
on your right side.
— Hang the machine on your shoulder(s)
with the shoulder harness.
— Ensure a safe footing. Never work on a
ladder or in a tree.
— Avoid over-reach.
— Keep cutting tool below waist level.
— Keep all parts of your body away from the
rotating cutting tool and hot surface.

the cutting tool attains enough speed for cut-
ting. It reduces the risk of kickback and entangling
weeds.
13. Take a rest to prevent loss of control caused
by fatigue. We recommend to take a 10 to
20-minute rest every hour.

16. Do not operate the tool in bad weather or if
there is a risk of lightning.
Cutting Tools
1. Use a suitable cutting tool for your work.
— 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.
Always use the cutting tool guard properly
suited for the cutting tool used.
2. When using a nylon cutting head, use only
manual. Never use wire or wirerope. They can

manual.
4. When handling the metal blade, always wear
gloves and put the blade cover on the blade.
The blade can cut bare hands.
5. When using metal blades, avoid “kickback”
and always prepare for an accidental kickback.
See the section Kickback.
Kickback (blade thrust)
Kickback (blade thrust) may occur when the spin-
-
diately cut. It can be violent enough to cause the
unit and/or operator to be propelled in any direc-
tion, and possibly lose control of the unit, resulting
-
ing if the blade snags, stalls or binds and is more
material being cut.
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.1
To avoid kickback:
1. Apply the segment between 8 and 11 o’clock.
2. Swing the tool evenly in half-circle from right
to left, like using a scythe. This allows the
proper segment of blade to contact plants to be
cut.
3. Never apply the segment between 12 and 2
o’clock.
4. 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.

5. Never use cutting blades close to solids, such
as fences, walls, tree trunks and stones.
6. Never use cutting blades vertically, for such
operations as edging and trimming hedges.
