Step 3. Open the cover in the front of the machine and take out the accessories pack placed on the workbed. Check
that you have received all of the following: a power cord, a ground wire, USB and Ethernet cables, a USB
fl ash drive with engraving software included, a water pump and water piping, an exhaust pipe with a hose
clamp, a set of hex wrenches, a tube of silicone sealant, an acrylic focusing tool, keys, and this manual.
Step 4. CAREFULLY remove the rest of the foam packaging material from around the laser tube, the viewing
window, and the rest of the machine. The laser tube is a highly fragile object and should be handled delicately
and as little as possible.
Step 5. Inside the main bay, remove the nylon cable ties from the X axis and the honeycomb table.
Step 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.
3.4 Electrical Grounding
This device 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 suffi cient grounding. If you do not have access to a 3-prong outlet, you MUST use the
grounding cable and ensure its proper connection. The far end of the cable should be securely connected to a single
metal rod driven at least 8 feet (2.5 m) deep or to two separate metal rods driven at least 4 feet (1.2 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 5Ω.
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.
