GENERAL SAFETY RULES
It is essential to follow the instructions in this manual to ensure the
safety of persons operating or in the vicinity of the machine.
1. Contact with oil
At the time of oil changes or when working on any components which
may retain hydraulic pressure, ALWAYS wear adequate safety equipment
Body
Protection
Gloves Face
Visor
-In the event of contact with the skin:
If a high pressure jet of oil is applied to the skin there is a danger of the oil penetrating
the surface. The injured person should be taken to hospital even if no wound is apparent.
Remove all contaminated clothing. Wash the suspected area immediately with plenty of soap
and water.
-In the event of contact with the eyes:
Wash immediately with plenty of water. Hold the eyelids apart for at least 15 minutes.
-Ingestion:
Risk of vomiting and diarrhoea. Do not make the person drink to avoid the risk of inhalation by
the respiratory tracts. Do not drink water.
-Aspiration:
If there is a suspicion that the person may have inhaled oil into the lungs (when vomiting for
instance), take them to hospital immediately.
In all cases seek immediate medical attention
2. Noise / dust
Take necessary precautions against the risk
of exposure to noise and dust during working
and travelling periods.

3. Vibrations
To improve safety and health conditions of workers, the decree 2005-746 from July 4th, 2005 forces
the employer to evaluate the levels of exposure of its employees to the vibrations transmitted to the
whole body, and to start protection of the driver beyond exposure limit values.
These daily exposure limit values are precised in the article R 231-119 of the Labour regulation.
Noremat carried out trial runs to evaluate the level of vibrations emitted by a tractor /machine unit and
transmitted to the operator’s seat. As an indication, the median value recorded is 0.45m/s2 per eight
hours base period in normal work conditions as recommended by the manufacturer.
4. Heat
Take necessary precautions against the risks
due to the heat released by the hydraulic
components (hoses, pump, motor, gearbox,
valve block, rotor shaft).
Wear heat
protection
5. Delivery
Observe safety and handling rules, in particular:
-only use designated slinging points for all slings.
-never lift the machine with slings that are in poor condition or are too weak in lifting capacity.
-check that the means of lifting is satisfactory and suitable to lift the load.
-never stand or walk under the load.
-never attempt to remove the delivery supports (blue pieces) before tting
of the machine has been completed.

Precautions for carriage when not tted to a tractor or carrying vehicle:
It is essential to lock the arm with the locking kit (blue supports)
supplied with the machine (Figures 1.02, 1.03, 1.04, 1.05, 1.06).
Contact NOREMAT who can supply you with the correct locking kit.
For safety reasons, the equipment is delivered in the ‘delivery’ position. In this position, machine
movements are locked by supports that serve both for lifting the machine and for anchoring it
to the lorry.
These supports are identied by their unusual blue colour.
When it is delivered, the machine is unloaded and placed on the ground on it’s stands at the correct
height to be tted to a standard tractor.
The supports should not be moved until the machine is tted to the tractor and started.
Observe lifting safety rules. In particular:
-use only designated points to attach slings and lift only at these points shown

2 7Dual-Pressure‘breakback’systempressures
Your machine is equipped as standard with an arm ‘breakback’ system called Dual-Pressure
(gure 1.18) French patent applied for 15th Sept 2004.
Normally, in the event of meeting an obstacle or when the forward speed is too high for the vegetation
being cut, the pressure rises in the orientation cylinder of the machine. When a designated pressure is
exceeded, a regulating valve opens and allows the arm to ‘breakback’ towards the rear.
In the Dual-Pressure system, the opening pressure of the regulating valve depends on the position of
the arm. If the distance from the centre-line of the tractor to the tool is more than the halfway reach
point, the pressure necessary for ‘breakback’ will be increased, or reduced if nearer.
