The contents of this manual are subject to change without notice. If you have any questions about the contents of this manual, or find any errors or omissions in it, please notify Unitek Miyachi Lasers. Unitek Miyachi Lasers is not responsible for any losses due to improper use of this product. - Page 5 Do not look at or touch the beam. Both direct laser beams and scattered laser beams are highly dangerous. If the beam enters the eye directly, it can cause blindness. LM45 Nd:YAG LASER MARKER 990-518...
- Page 6 Do not use a damaged power cable, connecting cable or plug. A damaged cable or a plug can cause electric shock, short circuits and fire. If any part needs to be repaired, consult Unitek Miyachi Lasers. or your distributor. Use only specified cables.
- Page 7 If the cable is pulled to disconnect the plug, it may be broken, and that can cause electric shock and fire. When leaving the laser marker unused for a long time, disconnect the power plug from the power outlet. Deterioration of insulation can cause electric shock, leakage and fire.
