Carefully read this Manual before proceeding with maintenance, repairs, refuelling or other machine operations. Repairs have to be carried out only by authorized and instructed staff; specific precautions have to be taken when grinding, welding or when using mallets or heavy hammers.

• Non-authorized persons are not allowed to repair or carry out maintenance on this machine. Do not carry out any work on the equipment without prior authorization. Ask your employer about the safety instructions in force and safety equipment.
• Nobody should be allowed in the cab during machine maintenance unless he is a qualified operator helping with the maintenance work. If it is necessary to move the equipment to carry out repairs or maintenance, do not lift or lower the equipment from any other position than the operator’s seat.
• Never carry out any operation on the machine when the engine is running, except when specifically indicated. Stop the engine and ensure that all pressure is relieved from hydraulic circuits before removing caps, covers, valves, etc. All repair and maintenance operations should be carried out with the greatest care and attention.
• Service stairs and platforms used in a workshop or in the field should be built in compliance with the safety rules in force. Any functional disorders, especially those affecting the safety of the machine, should therefore be rectified immediately.
