SAFETY IN THE WORKPLACE:
Most of the accidents which take place while the operator is using the machine or the equipment or during
their maintenance or repair are caused by a lack of compliance with the basic safety precautions. It is
necessary, therefore, to become more and more conscious of the potential risks of one's action by constantly
paying attention to one's own actions and their effects.
If potentially dangerous situations are known, accidents can be prevented!

All operators using the equipment must be competent and necessarily meet the following features:
Physical: good eyesight, coordination and capability of carrying out all functions required for the machine's
use.
Mental: Capable of understanding and applying the established rules and safety precautions. Users must
pay attention and be sensible for their own and other people's safety.
Training: users must have read and studied this manual, any enclosed graphs and schemes and its
identif cation and danger plates. They must be skilled and trained on any use or maintenance activities.
WORK CLOTHING:
When working and especially when executing repair or maintenance activities, it is necessary to wear the
following clothing and safety accessories:
- Overalls or other comfortable clothing, not too loose to prevent the possibility that parts of them
might be caught in the moving parts.
- Accident prevention shoes.
- Protective gloves for hands.
- Protective glasses or faceplate to protect eyes and face.
