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.
