5.6 Parts Replacement

• ALWAYS completely disconnect the engraver from its power supply before
replacing any parts.
• Take special care when replacing the laser tube or its power supply, as both
have extremely high voltage connections.
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. 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.
