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 keeping the cutting device at a distance

from the operator.

• Cutting near fences/foundations (Fig. 13)

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

become worn; if it gets tangled in a fence it could

break abruptly.

In any case, cutting around pavements, founda-

tions, walls, etc. can cause greater wear than nor-

mal in the line.

• Cutting round trees (Fig. 14)

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.

15)

This machine is tted 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 o the excess length.

END OF OPERATIONS

When you have nished your work:

– Switch o the engine as indicated above (Chap.

6).

– Wait for the cutting device to stop and t the

blade guard.

Before tackling a mowing job for the rst time it

is advisable to gain the necessary familiarity with

the machine and the most suitable cutting tech-

niques, nding out how to wear the webbing cor-

rectly, rmly gripping the machine and making the

movements required by the job.

• 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,

foundations, pavements, around trees, etc. or to

completely 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

WARNING!

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 peri-

odically and remove the weeds wound round the

machine, so as to prevent the drive tube from over-

heating due to the grass caught under the guard.

Remove the caught-up grass with a screwdriver to

allow the rod to be properly cooled.

WARNING!

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. 12)

Proceed at a regular pace, with a circular motion

similar 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 dis-

tance from the ground.

For heavier cutting it can be useful to tilt the cutting

line head by about 30°.
