General precautions
1 Operate always in a clean and dry environment.
2 Clean carefully the working environment and the machine before carry out the maintenance operations (Fig. 5).
3 Use only cleaning product in agreement with the regulations and always use them in the prescribed way.
4 Do not inhale chemical substances in dangerous concentration for the health care (Fig. 6); ventilate the environments in which sprays and solvents, with volatile chemical substances, are used.
5 Wear suitable clothing and protection such as overalls, safety gloves and ear safety devices (Fig. 7).
WARNING: Safety goggles must always be worn while carrying out every assembling or disassembling operations (Fig. 8).
6 Use suitable ear protection, like ear plugs, to keep out noise and prevent injury to the ears. A prolonged exposure to noise can damage your hearing.
7 The operator must be very careful with the equipment. Do not use headphones to listen music while you are working on the product or on the group.
