Category 2, 3-point hitch tractors up to 160 HP.
SYMBOLS
This booklet contains three "safety pictograms" which highlight the relevant danger
levels or important information:
It draws the operator's attention to special situations
which may jeopardize people's safety.
It draws the attention to situations which unfavorably
affect the machine efciency, but not people's safety.
It is used for general information, when people's safety
or the efciency of the parts are not at risk.

SAFETY
SAFETY IN THE WORKPLACE
Most of the accidents, which occur while the operator is using the machine or the equipment or
carrying out maintenance and repair activities, are caused by the non-compliance with the main
safety requirements. Therefore the potential risks must be fully understood and special attention
must be paid to the activity which is being executed.
If potentially dangerous situations are known,
accidents can be prevented!
USER'S REQUIREMENTS
The equipment user must have the following:
Physical: good sight, co-ordination and capability to execute all instructions in a safe manner.
Mental: the users must understand and follow the prescribed norms, rules and safety measures.
They must be careful, pay attention to their own safety and the safety of other people and act
properly and in a responsible way.
Training: the users must read and understand this manual, its pictures and charts, and the
identication and hazard plates. They must be specialized, trained and qualied on any use
and maintenance activities.
WORK CLOTHING
The following clothing and personal protective equipment must be used when working and
executing maintenance and repair activities:
• Overalls or any other comfortable outt; make sure that
they are not too loose since they might be caught by
moving parts.
•Protective gloves.
•Goggles or mask to protect the eyes and face.
•Safety helmet.
•Safety shoes.
Wear only personal safety accessories in good

SAFETY
PREPARATION
Preparing For Work:
•Do not drink alcohol, take drugs, or any other substances which may affect your
ability to use the equipment before or when working.
• Make sure that there is sufcient fuel in the tractor to prevent the machine from
stopping during work.
•Do not use the equipment under unsafe conditions, e.g. do not make temporary repairs
just to start or keep working; do not work at night if the area is not well illuminated.
When working or executing maintenance activities, remember:
•The labels and stickers providing instructions on the use of the equipment or
information on dangers must not be removed or hidden, and must be legible.
•Do not remove the safety devices, covers and safety guards, unless maintenance
activities are being carried out. If the safety devices must be removed, turn the engine
off, remove them correctly and re-install them before turning the tractor on.
•Do not lubricate, clean or adjust moving parts.
•Use the appropriate tools to execute maintenance or adjustment activities on the
equipment.
•Do not use damaged or unsuitable tools, e.g. pliers rather than wrenches etc.
•Prior to carrying out activities on hydraulic lines under pressure, or disconnecting their
components, make sure that the line is no longer under pressure and that it does not
contain any hot uids.
• Check all the ttings and make sure that they are well connected before supplying
pressure to the hydraulic lines.
•Make sure that no tools, clothes or any other materials are left in areas where moving
parts are present when the maintenance and repair activities are completed.
•Do not give directions and make signals at the same time during a maneuver.
Maneuver directions and signals must be given from one person only.
•Do not unexpectedly call an operator, if not necessary. Do not startle the operator, e.g.
by throwing objects.
• Pay attention to people in the vicinity of the work area, especially children!
•Make sure that nobody is standing in the working range of the equipment.
•Do not use the equipment to lift people.
• When the equipment is not needed, turn the engine off, leave the vehicle on a at sur-
face, with the rst gear and the parking brake engaged. Disengage the power take off.
•Do not execute any cleaning, lubrication, repair or adjustments when the engine is
running and the equipment is in the raised position.
•Do not work on steep slopes, if the stability of the vehicle can be jeopardized.
Manufacturer shall not assume any responsibilities if these instructions are not
strictly followed.
