Precautions to take before using the
machine
Do not wear loose clothing which could become caught
up in moving parts.
Wear the appropriate protective clothing for the work in
hand (gloves, shoes, goggles, helmet, ear defenders,
etc.).
Ensure that all operating controls (ropes, cables, rods,
etc) are placed so as they cannot be operated
unintentionally and cause damage or injury.
Before operating the machine, check tightness of nuts
and bolts, particularly on fixing elements (tines, forks,
blades, knives, etc). 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, 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.

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)
