Precautions when driving
Tractor handling, stability, performance and braking
efficiency are all affected by weight distribution, trailed or
mounted implements, additional ballast and driving
conditions. It is therefore of great importance that the
operator exercises caution in every given situation.
Groundspeed must be adapted to ground conditions as
well as to roads and paths. Always avoid abrupt changes
of direction.
Be particularly cautious when turning corners, paying
attention to machine overhang, length, height and
weight.
Never use a narrow track tractor on very uneven or
steeply sloping ground.
Never leave the tractor seat while the machine is
operating.
Carrying people or animals on the machine when
working or in transport is strictly forbidden.
Safety
9
Precautions when driving on public roads
Dimensions
Depending on the dimensions of the machine, contact
the relevant authorities to ensure that it can be legally
transported on public roads.
If the machine is over the maximum legal size, follow the
local regulations for special transportation of oversize
equipment.
Gross weight and weight per axle
Check that the tractor's authorized gross weight as well
as its lift capacity and maximum weight per axle are not
exceeded.
The front axle load (1) must never, under any
circumstances, be less than 20% of the tractor's unladen
weight. If necessary, add ballast weights to the front or
to the rear to preserve the steering and braking

Hydraulic circuit
Silo unloader - Straw Spreader
ALTOR 6070
Caution! The hydraulic circuit is under high pressure.
Maximum pressure at work: 215 bar.
Before connecting hoses to the tractor hydraulics,
ensure that tractor and machine circuits are not under
pressure. Before disconnecting a hose, depressurize the
hydraulic circuit.
To avoid making incorrect connectio ns, mark hydraulic
couplers and corresponding hoses with colors.
WARNING! Functions could be reversed (for example:
lift/lower) and cause accidents.
Regularly check the hydraulic hoses. In case of normal
wear, replace the hydraulic hoses every 5 years.
Damaged or worn hoses must immediately be r eplaced.
When replacing the hydraulic hoses, only use hoses with
the specification recommended by the manufacturer of
the machine.
To locate a leak, use appropriate means. Protect body
and hands from liquid under pressure.
Any liquid under pressure (particularly oil from
hydraulics) can penetrate the skin and cause severe
injury. If injured, see a doctor immediately, there could
be danger of infection.
Before any adjustments, maintenance or repairs are
carried out, lower the machine to the ground,
depressurize the hydraulics, turn off the engine, remove
ignition key and wait until all moving parts have come to
a complete stop.

Use only PTO shafts supplied with the machine or
recommended by the manufacturer.
The protective shield of the tractor PTO stub, the PTO
shaft guards and the protective covering of the machine
input shaft must always be in place and in good
condition.
Make sure that the PTO shaft guards are secured with
the safety chains provided.
Any worn or damaged guards must be replaced
immediately. A worn guard or an unpro tecte d PTO shaft
can cause a serious or even a lethal accident.
Do not wear loose clothing that could be caught in the
rotating PTO shaft.
Before attaching or removing a PTO shaft, or before
doing any work on the machine, disengage the PTO
drive, turn off the engine, remove ignition key and wait
for all moving parts have come to a complete stop.
If the primary PTO shaft is equipped with a slip clutch or
a free wheel, these must be fitted on the machine side.
Ensure that the PTO shaft is always correctly fitted and
locked into place.
Before connecting the PTO shaft, ensure that the PTO
speed (rotational frequency) and directions of rotation
are in line with manufacturer's recommendat ion s.
Before engaging the PTO drive, make sure all people
and animals are clear from the machine. Never engage
the PTO drive when the tractor engine is stopped.
When uncoupling the machine, rest the PTO shaft on the

Precautions and prevention of fire risk
Your machine works with moving parts (bale
separator(s), turbine) and highly inflammable products.
There is therefore a real risk of fire resulting from:
- Overheating of the power takeoff friction limiter.
Please do not use this limiter excessively. If smoke
issues from the transmission, stop the machine
immediately and leave the limiter to cool outside the
buildings.
- Winding strink or products at the ends of the bale
separator(s). Each time, before using the machine,
check the ends of the bale separator(s) to remove
products which have become wound round or have
accumulated in this area.
- Worn bearing. Grease bearings regularly and check
their condition.
- Sparks caused by pebbles or metal objects in the
straw.
