Note: Emission of airborne noise. The noise produced by the machine varies according to the soil
features at work. Exposure also depends strictly on the noise produced by the tractor. Considering the
data in the literature relating to similar equipment, it can be considered an approximate value of
exposure to the noise determined by the tractor between 90 dB (A) and 95 dB (A).
Verify the level of exposure to the noise with the proper instruments each time any work is performed. Follow the legislative
references of your country to identify the personal protective necessary equipment

4 - Handling and machine transportation.
(*note 3 mod. hi)
- The machine must be handled with lifting equipment Make sure that such equipment (including
the straps and the strings ) have a carrying capacity appropriate to the weight to be lifted and that
they are in good maintenance conditions.
The machine can be anchored:
a) while unpacking it (three point linkage frame not assembled): through the coupling point on
the machine (Fig. 4a).
b) machine completely assembled through the three point pin (Fig. 4b)
Due to the centre of gravity, the machine will lean about 20° while lifting it.
In order to make handling operations safely , always wear safety shoes and
make sure that there are no people or animals nearby while working
- The machine must be transported by professional means of conveyance (trucks, vans, etc.).Do
not use carry the machine in a car. In all cases, before transporting the machine , make sure that it is
well anchored with straps and strings and that it is stable enough. The anchor points can be the
roller group support, the three point linkage pin, the coupling tractor arms, and the front scraper.
Make sure that the scraper adjustment screws are properly tightened.
Always check that any walkways, ramps, etc. that must be crossed are well anchored and have a
capacity capable of supporting the total load of the vehicle + machine + operator. When using ramps
for loading, ensure that the vehicle has the handbrake on and have been positioned the wedges
suitable for locking the wheels
