5.5 Parts Replacement
• Be sure only to use identical or compatible replacement parts with this
engraver. Contact your vendor or our technicians if you have any questions
about fitment. Using incompatible components is highly dangerous and
waives all the manufacturer's liability for any damage or injury caused.
• ALWAYS completely disconnect the engraver from its power supply before
replacing any parts.
The engraver should not be modified or disassembled by anyone except trained and skilled
professionals, but some consumable parts may require replacement after prolonged use.
Take special care when replacing the laser tube or its power supply, as both have extremely high
voltage connections.
If you replace the power supply with an identical model, you will be able to use the same screw
terminal blocks as a unit. If you change to a different laser power supply, refer to the following
