Maintenance

Chassis Cleaned and Lubricated: 1/7/18
Mirrors Cleaned: 04/10/18
Lens Cleaned: 4/10/18

Chassis should be lubricated with sewing machine oil. Mirrors should be cleaned using a cotton swab and alcohol. Start in the center of the mirror and rotate out to the edges. The lens can be cleaned in the same manner as the mirrors. Unlike the mirrors, the lens must be removed from the laser in order to clean it. Take care to avoid touching the lens surface with your fingertips, and be sure to reinstall the lens with the correct orientation (concave face should face up).

Usage Notes

  • DO NOT use this machine if you have not been checked out on it. Members who can check you out include Tim, Zak, Avi, and Steve.
  • Running the laser at full power will significantly shorten the laser life. The maximum power setting used should be 80%.
  • Certain materials can release dangerous and damaging fumes when cut or engraved. DO NOT cut any material unless you know exactly what the material is and that it is safe to cut/engrave. See this page for more information. Note that this should not be considered the final authority - it is your responsibility to know what you are cutting and whether it is safe.
