Cleaning steps
Turn off the machine and remove the louver or smoke exhaust pipe from the machine.
Clean the exhaust fan with a tissue or cotton swab moistened with clean water or alcohol.
Install the louver or smoke exhaust pipe back to the machine. Otherwise, laser beams may leak out, and your
hands may get hurt if touching the fan.
Knowledge about parts and accessories
For laser machines, the key is a physical security device used to control processing access. You need to insert it into the
machine to unlock the processing and related functions. You can remove it to prevent others from using the machine
without your consent.
Cleaning the exhaust fan can:
■ Maintain the cooling efficiency: Whether the exhaust fan is clean
affects its rotation speed and cooling effect. If too much dust and
dirt accumulate in the exhaust fan, they will obstruct the airflow
and reduce the heat dissipation efficiency, and may even cause
the laser to overheat, affecting the proper operation of the
machine.
■ Maintain system stability: Keeping the exhaust fan clean and
working properly helps maintain the stability of the thermal
management system in the laser module, preventing the laser
module from degradation or malfunctioning due to heat
dissipation problems.
■ Extend its service life: Keeping the exhaust fan clean prevents it
from being damaged too quickly. Dust and dirt may cause the
exhaust fan to rotate unevenly, increase wear, and shorten its
service life.
■ Keep the key properly. When you don't use the machine, remove the
key and keep it in a safe place to avoid loss or theft. Only authorized
people can possess and use the key.
■ Perform regular checks. Check the status of the key regularly. If it can't
be inserted properly, repair or replace it promptly.
■ Follow the operation instructions when using a laser machine. Use the
key to lock or unlock laser processing functions at the right time.
Emergency stop switches are very important safety devices in mechanical machines. An emergency stop switch cuts off the
power supply of a machine in an emergency and thus protects the operator and the machine.
Generally, they are red buttons and some of them may be labeled "STOP" to warn operators. They may be in the shape of a
mushroom or cylinder, and some of them may come with LEDs to stand out.
How to use
■ When an emergency occurs, press the switch down
hard for a while to cut off the power supply of the
machine.
■ After the emergency is over, turn the button clockwise
about 45° to release it, and then restart the machine.
Cautions
If the exhaustion of smoke slows down during processing, the exhaust fan may have accumulated too much
dust. You need to clean it promptly.
