 6.4  OPERATION

NOTE

    Before starting any tasks for 

the first time, get to know the machine, 

learn the most suitable cutting techniques, 

make sure your are wearing the harness 

correctly, grip the machine firmly and make 

the movements required by the job.

To use the machine proceed as follows:

• 

always keep the machine connected to the 

correctly worn harness (see par. 6.1.1).

• 

when working, the machine must always 

be firmly held in both hands, keeping the 

power unit on the right of the body and the 

cutting unit below the line of the belt.

 6.4.1 

Work techniques

6.4.1.a 

Cutting line head

  Use ONLY nylon lines. The use of 

metal lines, plastic coated metal lines and/

or lines that are not suitable for the head 

can cause serious injuries and wounds. 

Do not use the machine for sweeping, 

tilting the cutting line head. The engine 

is powerful enough to throw objects and 

small stones 15 metres or more, causing 

damage to objects and injury to people; 

a. 

Cutting motion (Scything) 

Proceed at a regular pace, with a circular motion 

similar to a traditional scythe, without tilting the 

cutting line head during the operation (Fig. 17). 

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 to the left by about 30°.

  Do not work in this way if there 

is the possibility of causing objects 

to be thrown, which could harm 

people, animals or cause damage. 

b. 

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 

means at a distance from the operator.

c. 

Cutting near fences/foundations

Move the cutting line head slowly 

towards fences, posts, rocks, walls, etc. 

without hitting them hard (Fig. 18). 

If the line strikes a solid object it could 

break or become worn; if it gets tangled 

in a fence it could break suddenly.

In any case, cutting around pavements, 

foundations, walls, etc. can cause 

greater wear than normal to the line.

d.  Cutting around trees

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 (Fig. 

19

).

Remember that the nylon line could lop off 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.

6.4.1.b 

3 point, 4 point and 8 point blades:

Start cutting from above the vegetation and then 

descend with the mowing blade to cut branches 

by chopping them into small pieces (Fig. 

20

).

6.4.1.c 

Saw blade (if allowed):

Where permitted, the saw blade 

must be used with the specific guard 

always fitted (section 4.4.2). The blade 

should always be well sharpened 

to reduce the risk of kickbacks. 

When felling small trees, assess the 

direction of fall of the tree when cut, taking 

wind direction also into consideration. 

To obtain good results when felling small 

trees, make the cut with rapid movements 

towards the branch or trunk to be cut 

with the engine at maximum rpm.

Avoid using the right side of the blade since their 

is a high risk of kickback or jamming the blade 

in view of the direction of rotation (Fig. 

21

).

 6.4.2 

Adjusting the length of the 

cutting line head during work

This machine is fitted with a semi-

automatic wire release head.
