USE & SAFETY CHECKLIST

Do not operate with cover open.
Do not leave laser unattended when in use. Be on the lookout for fires. Use Emergency Stop Button immediately if you see a flame.
Open vent before turning on laser. Verify chiller is operating.
Learn the location of the emergency stop button (large red button, top right).
NEVER turn off the chiller buttons.
Max 70% power, never increase it over 70% in Lightburn.
Verify material will not be moved or blown away by exhaust. Use small magnets to hold down material if necessary. Place magnets where they will not come in contact with the laser head.
Double-check your settings before starting the cut job. Check Z-axis, location of material on x and y-axes, power, speed, and focus.
Do not cut overly warped material. doing so may damage laser. If there is a small warp, place warp upwards (like a rainbow, not a smile).
If cutting clear, glass-like material, confirm it is acrylic or Plexiglass, not polycarbonate.
Wait for exhaust fan to clear away smoke and fumes before opening the machine to remove your workpiece.
Do not manually move laser head. Do not attempt to calibrate or adjust mirrors without assistance.
Don’t cut high-risk materials that can catch fire or produce toxic fumes.
Allow laser to cool down after a long or intensive job before shutting it off.
