Usage
Don't use the following materials :
- PVC plastic of other material containing chlorine,
- Teflon or other materials containing fluorine,

If you are not sure you can use this diagram to identify the material
ALWAYS keep an eye on your job when the laser is working. Don't leave it unattended.
After each use clean the laser (lens and mirror) with a cotton swab and aceton, do not exert pressure on the lens while cleaning.

Maintenance
Clean the lens and mirror after each job or at least once a day. Use cotton stick with aceton and lightly brush the surface of the mirror/lens.
Keep the rods oiled (no WD-40)
I (Duality) Quote:
Never use wd-40 as a lubricant. The primary ingredients in wd-40 are kerosene and mineral spirits, which can be corrosive and are otherwise not suitable for mechanical lubrication.
Also you don´t want a (wd-40) sprayed mirror ;).
