18) Before releasing the equipment from the third point
attachment, put the hoist command lever into the locked
position and lower the support feet.
19) Only operate when visibility is good.
20) All operations must be carried out by expert personnel,
equipped with protective gloves, in a clean and dust-free
environment.
Tractor hitch
21) Hook the equipment to a suitable, sufficiently-powered tractor
by means of the appropriate device (lifter), in conformity with
applicable standards.
22) The class of the equipment attachment pins must be the
same as that of the lifter attachment.
23) Take care when working within the range of the lifting arms
as this is a very dangerous area.
24) Be very careful when hooking and unhooking the equipment.
25) It is absolutely forbidden to stand between the tractor and
linkage for manoeuvring the lifting controls from the outside
(Fig. 3).
26)It is absolutely forbidden to stand in the space between the
tractor and the equipment (Fig. 3) with the engine running.
Enter between only after having activated the parking brake
and placed a properly-sized jam or rock under the wheels to
block them.
27) The attaching of additional equipment onto the tractor brings
about a different distribution of weight on the axles. Check
the compatibility of the tractor performance with the weight
that the seeder transfers onto the three-point linkage. If in
doubt consult the tractor Manufacturer.
28) Comply with the maximum admissible weight for the axle,
the total mobile weight, transport regulations and the highway
code.
Transport on Road
29) When driving on public roads, be sure to follow the highway
code of the country involved.
30) Any transport accessories must be provided with suitable
signs and guards.
31) It is very important to remember that road holding capacity as
well as direction and braking capacity can be influenced,
sometimes con-siderably, by equipment being either carried
or towed.
32)When negotiating curves, be aware of the variation in
centrifugal force exerted in a position other than that of the
center of gravity, with and without the equipment in tow, and
also take care on the road or sloped terrain.
33) For transport, adjust and fasten the lateral lifting arm chains
of the tractor; check that the seed and fertilizer hopper covers
are closed properly; lock the hydraulic lifting control lever.
34) Road movements must be performed with all tanks empty
35) For displacements beyond the work area, the equipment must
be placed in the transportation position.
36) Upon request the Manufacturer will supply supports and
tables for signaling of dimensions.
37) When the dimensions of carried or partially-carried equipment
conceal the tractor’s signalling and lighting devices, these
must also be installed on the equipment itself, in conformity
with regulations of the highway code of the country involved.
When in operation make sure that the lighting system is in
perfect working order. It is also important to remember that
the correct signalling sequence of the headlights includes
(Fig. 4):
A - Direction indicator;
B - Red position light;
C - Stop light
Maintenance in safety
38) Do not proceed with maintenance and cleaning if the power
take-off has not been disconnected first, the engine power
off, the hand brake pulled and the tractor blocked with a wooden
block or stone of the right size under the wheels.
39) Periodically check that the bolts and nuts are tight, and if
necessary tighten them again. For this it would be advisable
to use a torque wrench, respecting the values of the Table 1.
40) During assembling, main-tenance, cleaning, fitting, etc., with
the seeding machine raised, place adequate supports under
the equipment as a precaution.
41) The spare parts must correspond to the manufacturer’s
specifications. Use only original spares.
