5. Open the rear access door to carefully check the laser bay and bottom left access door for
any leakage. Once all tubes are checked, fill the chiller tank to a level near the top of the green
NORMAL range on the gauge with more laser-safe antifreeze or pure distilled water.
6. You may keep the packaging in case of future return but, if you dispose of it or any accessories,
be sure to do so in compliance with applicable waste disposal regulations (See
§
8.7 Disposal
Instructions on Page 133).
3.4 Electrical Grounding
This engraver employs a powerful laser. As discussed in the Safety Information above, it is
extremely high voltage and potentially dangerous, so users must securely ground it to avoid the
buildup of static electricity.
Using a standard 3-prong outlet will provide sufficient grounding. If you do not have access to
a 3-prong outlet, you MUST ensure the proper connection of a grounding cable. The near end
should be fastened to the ground port at the rear of the engraver. The far end of the cable should
be securely connected to a metal rod driven at least 8 feet (3 m) deep into soil located at least
5 feet (1.5 m) from the machine. The resistance along the line should be no greater than 5
Ω
.
Poor grounding WILL cause equipment failure and create a serious electrical
shock hazard. The manufacturer and/or seller bear(s) no responsibility and
assume(s) no liability for any damage, accidents, or injuries caused by bad
grounding connections.
