DESCRIPTION OF THE PROTECTIONS AND OF THE SAFETY SYSTEM
The dangerous working element of this machine is the spiral-shaped tool.
The access to such element is prevented by a movable protection.
The protection is completely made of stainless steel and has a grating (to
allow possible additions and to control the working cycle).
Its sizes comply with the PREN 953 - MPL 5 ED EN 294 standards.
When lifting the protection, a limit switch acts to switch the machine off
according to the directions of the EN 60204-1 and EN 60947-5-1 standards.
In any case, it is strictly forbidden to remove, to change or to damage the
protections of the machine in any way.
