Please follow each instruction carefully to ensure proper installation and avoid damaging your machine. Before beginning, make sure the engraver is powered off and unplugged to ensure your safety.

- Attach one side of belt to laser head and tighten the Phillips screws that hold it in place.
- With one side of the belt fixed in place measure the non-fixed end up to the laser head in order to cut belt to length.
- The new belt should fit all of the way under its clamp while having just a little play from the beam. Tighten up the two Phillips screws.
- Make sure belt runs in the center of the pulleys and does not rub any of the lips on the pulleys.
- Loosen Philips screw on cable tensioner from step 4 and let the spring add tension to belt. Once belt has tension tighten Phillips screw.
- Reinstall theI-beam cover that was removed in step 3.
