SAFETY
:
When operating the CNC laser attachment, you should always wear the red
protective glasses supplied with the unit. The laser should be operated with
extreme caution and avoid eye or skin exposure to direct laser light.
OTHER IMPORTANT INFORMATION TO KNOW
All lasers will emit smoke as they burn into the material, while the amount of the
2-watt version is minimal, the 4 and 7-Watt can be considerable. Excessive smoke
can shorten the life of the laser diode by clouding the lens causing it to reflect
back into itself and prematurely burning it out.
We highly recommend using some type of smoke removal system, such as a dust
collector, shop vac with Hepa filter, or an exhaust system like NWA item #20138
Laser Maintenance: After every hour of use, you should lightly clean the laser lens
with a cotton swab and hydrogen peroxide or a camera lens kit.
