Danger Informations
Precautions and warnings for safety are in this manual and in the system, where many warning plates are present, be sure to
make them readable. Every damaged plate must be replaced or cleaned with a cloth.
When replacing a component with plates, be sure that the spare part too has a plate, otherwise put a new plate before installation.
Here are listed the safety labels of the system:

Do not wear big clothes or jewels that can get caught in moving and rotating parts;
•
Wear helmet, gloves and any other protection clothes/devices needed;
