USING THE MACHINE

11

Choosing the cutting device

Choose the most suitable cutting device for the job to

be done, according to these general indications:

the 3-point blade

is suitable for cutting brush-

wood and small shrubs up to 2 cm in diameter;

the cutting line head

can eliminate tall grass and

non-woody vegetation near fences, walls, founda-

tions, pavements, around trees, etc. or to com-

pletely clean a particular area of the garden;

WORKING TECHNIQUES
a) 3-point blade (Fig. 11)

Start cutting above the undergrowth and then move

down with the scything blade so as to cut the brush

into small pieces.

b) Cutting line head

Use ONLY nylon lines. The

use of metal lines, plasticised metal lines and/or

lines not suitable for the head can cause serious

injuries and wounds.

During use it is advisable to stop the engine periodi-

cally and remove the weeds wound round the ma-

chine, so as to prevent the drive tube from overheat-

ing due to the grass caught under the guard.
Remove the caught-up grass with a screwdriver to al-

low the rod to be properly cooled.

Do not use the machine for

sweeping, tilting the cutting line head. The power

of the engine could throw objects and small

stones 15 metres or more, causing damage and

injuries to people.

Cutting in motion (Scything) (Fig. 13)

Proceed at a regular pace, with a circular motion sim-

ilar to a traditional scythe, without tilting the cutting line

head during the operation.
First try cutting at the right height in a small area, so

as to then achieve a uniform cutting height keeping

the cutting line head at a constant distance from the

ground.
For heavier cutting it can be useful to tilt the cutting line

head by about 30°.

WARNING!

WARNING!

Do not work in this way if

there is the possibility of causing objects to be

thrown, which could harm people and animals

and cause damage.

Precision cutting (Trimming)

Keep the machine slightly tilted so that the lower part

of the cutting line head does not touch the ground and

the cutting line is at the required point, always keep-

ing the cutting device at a distance from the operator.

• Cutting near fences/foundations (Fig. 14)

Slowly approach the cutting line head to fences,

posts, rocks, walls, etc. without hitting them hard.

If the line strikes a solid object it could break or be-

come worn; if it gets tangled in a fence it could break

abruptly.

In any case, cutting around pavements, foundations,

walls, etc. can cause greater wear than normal in the

line.

• Cutting round trees (Fig. 15)

Walk round the tree from left to right, approaching the

trunks slowly so as not to strike the tree with the line

and keeping the cutting line head tilted forward

slightly.

Remember that the nylon line could lop or damage

small shrubs and that the impact of the nylon line

against the trunk of bushes or trees with soft bark

could seriously damage the plant.

Adjusting line length when working (Fig. 16)

This machine is fitted with a “Tap & Go” head.

To release more line, tap the cutting line head against

the round with the engine at top speed: the line will be

released automatically and the knife cut off the excess

length.

END OF OPERATIONS

When you have finished your work:
– Switch off the engine as indicated above (Chap. 6).

– Wait for the cutting device to stop and fit the blade

guard.
