5. USE OF THE MACHINE

5.1 Correct use

The brushcutter must be used only to cut grass, bushes
and shrubbery (trunks with a max. diameter of 200
mm can be cut using a machine with elevated power
equipped with both a blade and a trunk-retainer guard
to CE standards).
- Wear the safety belts and adjust them to your height.
- After the engine has started, let it run for 2-3 minutes
Fig. 27
at the minimum level.
- Connect the brushcutter to the safety quick release
clip on the safety belts, or if the brushcutter has been
provided in the backpack version, wear it on your
shoulders.
- Make sure that the weight of the machine is evenly
distributed and perfectly balanced in such way that
the cutting organ is parallel to the ground and does
not require support from the grip (Fig. 25).
- Perform a few accelerations (without reaching the
maximum rpm) without doing work to make sure that
everything is functioning regularly.
Fig. 28
- With the cutting tool stationary in clear sight and con-
stantly under your control, reach the work position by
carrying the machine beneath the level of your waist
far away from your body, making sure that there are
no other people within a 15 meter radius (Fig. 26).
5.2 Use of the machine
You are now ready to begin working. Assume a stable
and balanced position on both feet.
Grass is cut as if operating in corridors 1.5 meters wide
Fig. 29
by moving forward step by step and swinging the machine
right and left. Make sure that you are standing securely
on both feet before taking a new step (Fig. 27).

When using the grass-cutter disks, always cut from
right to left and leave a pile of cut grass on the left for
subsequent recovery.
When using the machine to cut bushes or prun-
ing mount the CE-standard disk saw together with the
2
appropriate safety guard. You will reach the maximum
cutting capacity when the acceleration of the machine
is at its peak rpm and consequently the saw will have
a lower probability of jamming or stopping under these
Fig. 30
operating conditions.
In order to use this type of cutting tool correctly, the blade
must not be used in its critical sector (Fig. 28), given the
risk of the blade's rebounding (known kick-back). This
effect is sometimes strong enough to make you lose
control of both the machine and your balance, with the
consequent risk of injury.
We recommend cutting with side A of the disk saw for
ideal cutting control. Side B can also be used for cutting,
but there is less control because of the counter-clock-
wise rotation of the blade.
