LRQ-C Mounting
Dust Cover Removal and Installation
Use caution handling the shim as the edges are extremely sharp. For disassembly, simply remove the four screws securing the stainless steel dust cover shim and slide the shim out.
In most cases, the shim only needs to be lifted slightly to install the mounting screws and does not require full removal. Take care not to kink or bend the shim.
Move the stage at least 50mm away from one end of the LRQ base and feed the LRQ Dust Cover Shim in from one side. Use a business card as a ramp to help guide the shim over the first rise and under the second. Be careful not to kink the Dust Cover Shim or cut your fingers on the sharp metal!
Carefully feed the Dust Cover Shim through the stage top adapter, making sure that the shim doesn't rub directly on the aluminum of the Stage Top Adapter. Align the mounting holes at each end such that the Dust Cover Shim covers all of the magnet slots in the Sheet Metal Sides.
Take 2x M3x3 screws and thread them through the Dust Cover Shim and into the Dust Cover Shim Mount Away. Pull the shim as far as it can go towards the away end, and hand tighten the screws, ensuring that the Dust Cover Shim does not twist during tightening.
Take the remaining 2x M3x3 screws and thread them through the Dust Cover Shim and into the Dust Cover Shim Mount Home, leaving them loose. Push down on the Dust Cover Shim inside the Stage Top Adapter, and tighten the M3x3 screws.
When properly tensioned, the LRQ Dust Cover Shim should sit below the lid mounting ledge as indicated and should still have a slight bend. The LRQ Dust Cover Shim should be low enough that it does not contact the bottom of the LRQ Dust Cover Adapter Lid when installed, but it should not be so tight that it increases the drag of the stage.
Drive the LRQ stage back and forth through its full length a few times, and visually inspect that the Dust Cover Shim does not bulge anywhere during travel. If the shim bulges, loosen and then re-torque the M3x3 screw nearest the bulge in order to remove it. If loosening both screws on an end, you may need to push down on the shim inside the Stage Top Adapter again to add some tension. Repeat this process until the Dust Cover Shim stays flush with the Sheet Metal Sides through the full length of travel.
Take the LRQ Dust Cover Adapter Lid and place it in position on the Stage Top Adapter, ensuring that the countersink holes are on the top. Take the M2x4 screws and hand tighten them into the Stage Top Adapter.
