2.5.5 Risk of optical system
2.5.5.1 Routine operation
The reflector of the optical system is the gold plating silicon reflector, and the focus of the cutting head is made
from zinc selenide. In normal condition, these optical parts are free of danger.
However, polluted focus or focus with damaged coating will cause thermal decomposition by laser beam over 400℃
together with toxic smoke generated. At this time, the laser device must be powered off, mechanical movement
and blowing air to the lens must be stopped. At this moment, cleaning and parts replacement should be
performed.
When gold plating silicon reflector is decomposed by high temperature laser beam due to pollution or damaged
coating, the decomposition will generate dust and smoke containing silicone monoxide, steam of heavy metal. At
this time, it is a must to power the laser device off, stop running the equipment and keep good ventilation. When
all the smoke and dust are removed, it is to perform cleaning and replacement of lens.
2.5.5.2Warning for fire accident
Damaged equipment or improper operation of the equipment will cause risk of fire accident. Fire extinguisher
must be equipped according to fire control regulations prescribed by the state.
2.5.6Other risks
To ensure safety, modification or changing use of the equipment with no consent from the manufacturer is
strictly prohibited; any change of operating software or function to the equipment is strictly prohibited, or it is
strictly prohibited to perform integration of the equipment with other system.
During cleaning, please wear on goggle and gloves. The damaged parts must be sealed in a container and
properly packaged, and then returned to the manufacturer.
Good ventilation is required in case of any damage of the parts.
Atomizer or flammable or explosive substances are strictly prohibited to approach the equipment, make
regular check on the fire extinguishers to ensure a good condition.
