Onyx 90 Media Cutter
The World’s Best Media Cutter 828-388-5782
Important
In order for the machine to work properly, the cutting beds must be in line. Stand along the side of the
Onyx 90 and look down the cutting beds where the left and right cutting beds are attached to the vertical
axis extrusion. The cutting beds must not be bowed either towards the wall or bowed away from the wall.
Everything must be in line. This next adjustment will ensure that.
1. Loosen the four 1/4” x 20 x 2”screws and nuts located on the back of the vertical axis extrusion. The four screws
are located in the square tube attached to the vertical axis extrusion. Do not remove the screws - just loosen them
making sure that the safety screw & nut are in place.
2. Loosen the 5 mounting screws on the vertical axis extrusion and loosen the 4 screws on the horizontal wall brackets.
3. Using a straightedge placed against the front of the left and right horizontal extrusions, push or pull as necessary to
straighten and remove any gap between the straight edge and the horizontal extrusions.
4. While maintaining the pushing/pulling action, have an assistant tighten the four screws located in the square tube on
the back of the vertical axis extrusion.
Mounting the Media Clamp Assembly
1. Locate the ¼-20 tapped hole in the top mounting bracket of the bearing-tubes and cart assembly unit.
2. Insert the ¼-20 x 2 3/4” screw of the top mat clamp assembly into the tapped hole in the top mounting bracket of
the bearing-tubes and cart-assembly unit. Tighten the ¼-20 x 2 3/4” screw into the hole and jam the nut to secure.
3. Attach the bottom of the media clamp assembly to the T-nut in the left horizontal extrusion using ¼-20 x 1” screw
and lock washer.
4. Adjust the media clamp assembly so that it is the same distance from the vertical axis extrusion at the top and bot-
tom. When the distances are the same, tighten the screw to the T-nut.
5. You have completed the assembly and mounting of your new Onyx 90 Media Cutter.
6. Double check to make sure all screws and nuts are tight.
