Safety
Precautions to take before using the
machine
Ensure that all operating controls (ropes, cables, rods,
etc) are placed so as they cannot be operated
unintentionally and cause damage or injury.
Prior to each machine use, check tightness of bolts and
nuts, in particular those securing the tools (booms,
wheels...). Retighten if necessary.
Before operating the machine, ensure that all the safety
guards are firmly in place and in good condition.
Immediately replace any worn or damaged guard.
Precautions when driving
Tractor handling, stability, performance and braking
efficiency are all affected by weight distribution, trailedor
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.
When the main tank is full, reduce travel speed to limit
rolling movement in the tank.
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.

Gross weight and weight per axle
Description of symbols
The drawings are not legally binding, their only aim is to illustrate the method to use.
Prior to driving on public roads, check that criteria are met to be in conformity with the countrie's
regulations:
- When coupling a tool to the front and rear 3-point lift linkage, the maximum authorized
payload must not be exceeded.
- When coupling tools to the front and rear 3-point lift linkages, the maximum load on each
axle's tires must not be exceeded.
- The load on the tractor front axle must always represent 20 % of the tractor unladen weight.
For machines with hoppers or tanks:
- If the total unit weight exceeds the tractor Gross Combined Weight Rating in accordance
with the countrie's legislation, empty the hopper to travel on public roads.
- In any case, we recommend to travel on public roads with empty hoppers and tanks.
Description Units Description
T kg Tractor unladen weight
PTAC kg Gross Combined Weight Rating
T1 kg Unladen load on tractor front axle
T2 kg Empty load on tractor rear axle
t kg Axle loads (Tractor + machine)
t1 kg Load on front axle (Tractor + machine)
t2 kg Load on rear axle (Tractor + machine)
t1 max kg Maximum load authorized on the tractor front axle according to the tires

Stage 1:
To measure:
- Tractor tare (T).
Stage 2:
- Couple the machine to the tractor.
To measure:
- Load on front axle (t1):
• Tractor + machine (transport position).
To do:
- If the front axle load (t1) is below 20% of the tractor
tare (T), add ballast weights (M1) to exceed the
minimum load on the front axle.
Example:
• (T) = 7500 Kg (16535 lb)
• The front axle load must be of minimum 1500 Kg
(3300 lb).(20% of T)
• (t1) = 700 Kg (1545 lb).
• 700 Kg (1545 lb) < 1500 Kg (3300 lb).
• Add ballast weights until the minimum front axle
load is exceeded.
• Repeat checking procedure.

Stage 3:
To measure:
- Total weight (t):
• Tractor + machine (transport position).
• Ballast weights.
Checking:
- To go to the next stage:
• Check in the tractor's operator's manual that the
value measured is below the tractor's Gross
Combined Weight Rating.
To do:
- If t < PTAC go to the next stage.
- If the total unit weight exceeds the tractor Gross
Combined Weight Rating in accordance with the
countrie's legislation, empty the hopper to travel on
public roads.
Example:
• (t) = 10000 Kg (24250 lb)
•PTAC = 13000 Kg .
• t < PTAC : Go to the next stage.
Stage 4:
To measure:
- Load on rear axle (t2):
• Tractor + machine (transport position).
• Ballast weights.
Checking:
- Check in the tractor's operator's manual that the value
measured is below the maximum allowed tractor rear
axle load.
- Check that tyre and rim specifiations are in conformity
with the requirements of the tractor manufacturer.
Example:
• Load on rear axle (t2) = 8500 Kg (18740 lb)
• Check in the tractor's operator's manual that the
value measured is below the maximum allowed
tractor rear axle load.
• Check that tyre and rim specifiations are in
conformity with the requirements of the tractor
manufacturer.

Precautions when coupling
Prior to coupling the machine, check that it can't move
unexpectedly (place wedges underneath the wheels or
lock handbrake) and that the parking stand is the the
adequate position.
Never stand between the tractor and the machine when
operating the three point linkage.
Do not stand between the tractor and the machine
without ensuring that the parking brake is applied.
Hydraulic circuit
Caution! The hydraulic circuit is under high pressure.
Maximum pressure at work: 200 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 connections, 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 replaced.
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.
